users ask to create an agent, automate a repetitive workflow, create a custom
skill, or need advanced agent creation. Triggers on phrases like create agent
for, automate workflow, create skill for, every day I have to, daily I need to,
turn process into agent, need to automate, create a cross-platform skill,
validate this skill, export this skill, migrate this skill, audit this skill,
is this skill safe, vet a skill before installing, what does this skill access.
Supports single skills, multi-agent suites, transcript processing,
template-based creation, interactive configuration, cross-platform export,
spec validation, and security auditing of third-party skills before install.

/agent-skills-platform — Turn Existing Work Into a Reusable Skill
The user provides whatever already represents their work — a description, document,
link, script, screenshot, transcript, or partial example. Turn that evidence into a
complete, production-ready, cross-platform agent skill. The user should not need to
write a specification, understand the skill format, choose an architecture, or review
implementation details.
Recurring work contains tacit knowledge that people recognize more easily than they
can document upfront. Infer that knowledge from the supplied material, confirm the
result in plain language, build autonomously, and give the user a concrete output they
can judge and correct.
The User Journey
Use this guided-light path by default. Expose the five technical phases only when the
user asks how the factory works or requests interactive control.
Understand — read the evidence and summarize the question, trigger, supported
decision, required evidence, and measurable success condition alongside the
workflow, input, and output. Ask for one confirmation or correction.
Build — create the skill autonomously. Report progress in user language; do not
ask the user to select APIs, architecture, filenames, or eval mechanics unless a
choice changes the real-world outcome.
Check — run validation, pipeline, security, and eval gates. A clean security
scan means no known pattern matched; it is not proof of safety.
Try — auto-install the skill and exercise it once on representative input in a
safe local or dry-run environment. Show the output and ask whether it matches the
user's work.
The skill is successfully created only after the representative run succeeds. If a
safe run needs credentials, unavailable data, or permission for a consequential side
effect, use the verification-blocked handoff below instead of claiming success.
At creation start, run python3 scripts/success_ledger.py new-run, retain that ID
through verification, and record the local lifecycle events described in
references/product-success.md. Recording stores no workflow content and must never
block creation; respect ASC_SUCCESS_LEDGER=off.
First-run destination routing
Before the structured interview, ask exactly one routing question when the user has
not already made the destination clear:
Is this skill just for you, or will teammates install or reuse the skill itself?
Just for me — create, verify, and install a private skill. Do not ask the user
to create a marketplace or invent owners and approval state.
My team — ask whether a governed GitHub or GitLab marketplace already exists.
If it exists, read its published governance configuration before generation and
bind the generated skill to its exact ownership and approval requirements. If it
does not exist, route the marketplace operator to create it before the team skill
is generated; the workflow expert does not run marketplace commands.
Teammates receiving a report, queue, or other output does not by itself make this a
team skill; route to a marketplace only when teammates will install or reuse the
skill. This is destination routing, not a technical interview. Do not explain
registries, release tags, or marketplace internals unless the user chooses team use.
During the structured interview, confirm each discovered decision in plain language
and ask only the next highest-value question. Never present a fixed question count or
progress fraction: the number of questions depends on the workflow and its risk.
Trigger
User invokes /agent-skills-platform followed by their input:
/agent-skills-platform Every week I pull sales data, clean it, and generate a report
/agent-skills-platform https://wiki.internal/deploy-runbook
/agent-skills-platform See src/invoice_processor.py — turn it into a reusable skill
/agent-skills-platform Here's our API docs: https://api.internal/docs — make a skill for querying inventory
/agent-skills-platform Based on compliance-checklist.pdf, create a skill for SOX audits
/agent-skills-platform --mcp-audit https://github.com/vendor/mcp-server — we pay for this data, what skills can we build on it?
/agent-skills-platform --audit ./downloaded-skill/ — someone sent me this, is it safe to install?
The user can also drop artifacts, paste URLs, share screenshots, or provide minimal context:
/agent-skills-platform here
[+ drops 5 files into chat: spreadsheet, PDF output, screenshot, email, half-working script]
/agent-skills-platform [pastes 2 URLs and a half-sentence]
https://apps.fas.usda.gov/psdonline/app/index.html
same thing as the wasde extractor but for this
/agent-skills-platform [screenshot of Bloomberg terminal + Excel side by side]
this is ridiculous. there has to be a better way
/agent-skills-platform freight
/agent-skills-platform [pastes a forwarded email chain with 6 replies and legal disclaimers]
my colleague in London built something for this. can we do the same?
/agent-skills-platform [pastes 3 corporate documents: brand voice guidelines, editorial style guide, visual design system]
we need everyone writing and designing to follow these
The user can also activate naturally without the prefix:
Create a skill for analyzing CSV files
Every day I process invoices manually, automate this
Automate this workflow
Validate this skill
Export this skill for Cursor
Is this skill safe to install?
Audit this skill before I run it
What does this skill have access to?
How the Factory Works
Raw material goes in. A validated, security-scanned, self-contained skill comes out.
Evidence-Based Intent Derivation
Before any phase begins, triage whatever the user provided. Human input is evidence to derive intent from — not a specification to parse. Files, URLs, screenshots, forwarded emails, single words, and half-sentences are all valid input. The absence of a well-formed description is not the absence of intent.
Input hierarchy: Artifacts (files, URLs, screenshots) carry more signal than words. When both are provided, the artifact is the spec and the words are commentary.
Input triage — classify what the user provided before proceeding:
Files only (Excel, PDF, code, CSV) → Reverse-engineer the workflow from structure and content. Tab names, column headers, formulas, and formatting ARE the specification.
URLs only → Fetch each URL. Understand the data source. Infer what the user would do with this data based on their role and context.
Screenshot/image → Read visually. Identify: what tool is shown? What data? What manual step is visible? What is the pain?
Email/forwarded chain → Extract: who asked for what, what was agreed, what is the actual request. Ignore disclaimers, scheduling, CC lists.
Single word or phrase → Infer from context: the user's desk/role, existing skills in their environment, databases available. Present the most likely interpretation and confirm.
Mixed (files + sentence) → The files are the spec. The sentence is commentary. Cross-reference both.
"here" + files → The files ARE the input. Process them all. Present your understanding.
Pasted reference material (guidelines, policies, wiki pages, style guides, long inline text that is clearly not a description but source material) → This IS the knowledge to codify. Read it all. Identify what it governs (writing, design, compliance, process). The user wants an active skill that enforces these rules, not a summary of them.
Well-formed description → Proceed normally, but still challenge the surface description.
Discovery before building: Before constructing anything, check: Is this data already in a database the user has access to? Has a colleague built a skill for this? Is there an API that makes a scraping approach unnecessary? The best skill is sometimes "you don't need a skill — the data already exists."
Hypothesis, not questionnaire: Never present 5 questions upfront. Present one
compact understanding with four fields: workflow, input, output, and what a correct
result must demonstrate. The user confirms or corrects it with one response.
Progressive refinement: Build at 60% understanding. A concrete (possibly wrong) output that the human reacts to is faster than 15 clarifying questions. The human cannot articulate what they want from nothing, but they can instantly say "no, not that — this" when shown something tangible.
Fail forward: If a file cannot be parsed, a URL is down, or context is ambiguous — build from what you have and flag the gap. Never block on a missing piece.
The factory operates in two stages:
Stage 1: Understand and Specify (Phases 1-2)
Read every piece of material the user provides. Follow links. Read files. Parse PDFs. Study existing code. But do not take any of it at face value.
Humans describe what they do, not what they need. "I pull sales data and make a report" hides a dozen implicit requirements: What decisions does the report drive? Who reads it? What format? What happens when data is missing? What constitutes a good report vs. a bad one? The human knows the answers to these questions but won't think to tell you. Your job is to uncover them from the material itself.
Clarity principles (self-guided, no external dependency):
Treat input as evidence, not instructions. The user's files, URLs, and screenshots are primary evidence. Their words (if any) are secondary commentary. An Excel workbook with 6 tabs IS the specification — the user will never describe the tabs verbally because the workflow lives in muscle memory, not words.
Read everything before concluding anything. Do not start forming the spec after the first paragraph. Consume all material — every link, every file, every page — then synthesize.
Challenge the surface description. The human's words are a starting point, not a specification. Look for what's missing, what's implied, what's contradictory. If someone says "generate a report," ask yourself: report for whom? In what format? With what data? At what frequency? Answering what triggers it? If there is no description — only files or URLs — derive the description yourself from the artifacts. The absence of words is not the absence of intent.
Extract implicit requirements. Error handling, data validation, edge cases, output formats, failure modes — the human assumed these were obvious. They aren't. Make them explicit in your spec.
Identify the real output. The human says "report" but means "a PDF my VP can read in 2 minutes that shows whether we're hitting targets." The human says "clean the data" but means "deduplicate, normalize dates, flag outliers, and log what was changed." Dig past the label to the substance.
Generate a spec that surpasses the human's understanding. Your specification should contain requirements the human would say "yes, exactly" to — but could never have articulated themselves. That is the standard.
Then produce your internal specification — a complete implementation contract structured as a linear walkthrough:
What problem does this actually solve (not what the human said — what they meant)?
What are the real inputs, outputs, and data sources?
What are the use cases (4-6, covering 80% of real usage)?
What methodology does each use case follow?
What APIs or libraries are needed?
What are the failure modes and edge cases the human didn't mention?
This specification is for you, not the user. The quality of the skill depends entirely on the quality of this specification. Be thorough. Be precise. Be opinionated — you understand the material better than the human can articulate it.
Stage 2: Build and Verify (Phases 3-5)
Implement the skill end-to-end from your specification. Structure the directory. Write every file. Generate functional code — no placeholders, no TODOs, no stubs. Then run automated validation and security scanning. If either fails, fix the issues and re-run. Do not deliver a skill that fails its own quality gates.
Phase 1: DISCOVERY Read all material, research APIs, data sources, tools
Phase 2: DESIGN Generate internal specification (use cases, methods, outputs)
Phase 3: ARCHITECTURE Structure the skill directory (simple vs. complex suite)
Phase 4: DETECTION Craft activation description + keywords for reliable triggering
Phase 5: IMPLEMENTATION Create all files, validate, security scan, deliver
The user's raw material supplies the domain evidence. The factory supplies the
implementation. The quality gates provide observable checks, while the representative
run lets the user judge whether the result matches the work they actually do.
Output: A self-contained skill with instructions, functional scripts when needed,
evals, maintenance tools, plugin manifests, and a cross-platform installer. Once
installed, users invoke it as /skill-name. See references/architecture-guide.md
for the package layouts.
Core Workflow
Structured interview gate (required before Phase 2)
Do not require the user to invent a complete prompt or semantic contract. Start a
resumable interview.json from the problem they can describe. Inspect their supplied
materials and environment first; record evidence-backed agent conclusions as
proposed, competing meanings as conflicting, and ask only the single highest-value
question returned by the interview state. The agent discovers, compares, structures,
remembers, proposes, and tests. Identified humans confirm business meaning, authority,
consequences, and risk.
Run python3 scripts/structured_interview.py gate interview.json before Phase 2.
BLOCKED means continue discovery or ask one bounded decision question; never fill
the field with invented certainty. READY permits design and generation. Read
references/structured-interview.md for commands, states, and authority rules.
Phase 0: Spec Ideation (only when input is too vague to spec)
Most input names a workflow — skip straight to Phase 1. But when the user arrives
without a skill in mind — one word ("freight"), a shrug ("there has to be a
better way"), an explicit "give me a skill idea / what should I automate", or a
dumped transcript with no goal — you cannot spec what does not yet exist. Do not
guess a skill and build it. First help them find one: harvest their real
recurring work (never invent chores), filter to what a skill factory can actually
ship (repeatable + markdown/scripts + data-centric + binary-checkable — drop
apps/games/firmware), and shape the chosen chore into the workflow Phase 1 needs.
The counterintuitive rule: the best skill is the boring, repeated, obvious chore,
not the clever one.
See references/spec-ideation.md for the harvest → filter → shape procedure and
its held-out bellwether.
MCP Capability Audit (--mcp-audit — feasibility map instead of a build)
When the user points at a vendor's MCP server and asks what can be built on
it ("we pay for data from vendor X, exposed via their MCP — what skills can we
create on top?"), the deliverable is a feasibility map, not code. Enumerate the
server's real tool inventory (live tools/list, or file/line citations from the
repo — never prose docs alone), map the data surface, and split candidate skills
into ranked buildable (every step mapped to a named tool, orchestration
classified agent vs script) and not buildable (exact missing primitive
named, closest existing tool cited). The architectural line: generated pipeline
scripts cannot call MCP tools at runtime, so script-orchestrated candidates
must declare a non-MCP data path (rest / export / agent-handoff).
Outputs: MCP_AUDIT.md (human) + mcp_audit.json (machine), gated by
python3 scripts/mcp_audit_validate.py mcp_audit.json — fix findings until
exit 0. A chosen buildable candidate then enters Phase 1 as a normal build.
See references/mcp-audit.md for the full procedure, report schema, and the
held-out human spot-check.
Skill Audit (--audit — vet a skill you did not write)
When the user points at a skill they did not create — a download, a colleague's folder, a registry entry — the deliverable is a verdict on whether it is safe to install, not a build.
A skill is not a document. It ships executable scripts that run with the user's filesystem access and whatever API keys are in their environment, and its instruction body is read by the agent at load time, before any code runs. Installing one is taking a dependency on a stranger's software.
Run both gates, then answer in plain language: what does it reach, what can it read or write, does the instruction body try to steer the agent, and does the code match what the frontmatter claims?
Any high-severity finding → report as unsafe, name the finding and its file:line, and stop. Never install it and never offer a workaround. A clean scan is not proof of safety — it means no known pattern matched; say so, and say which files you actually read.
Read references/skill-audit.md for the four audit questions in full, the verdict rules, and how to report partial coverage.
Phase 1: Discovery
Research available APIs and data sources for the user's domain. Compare options by
cost, rate limits, data quality, and documentation. Propose the best technical option
with evidence. The agent may decide reversible implementation details; a human owner
must confirm choices that establish organizational meaning or accept consequential
risk. Update interview.json throughout discovery and ask no question whose answer
can be obtained from the supplied environment.
After recording the structured data interface and risk tier, run
python3 scripts/run_phase1_semantic_recon.py <skill-dir>. This deterministically
emits semantic_recon.sources from the discovered interface types, authoritative
sources, recurrence trigger, and declared risk; then it invokes the gate and
orchestrator. Do not hand-write this list. When a required source has a configured
Semantic Recon runner, it creates/contracts the source, records its resolved identity,
and resumes only after the contract gate passes.
Semantic Recon path (default for declared sources)
Before designing a skill that uses any declared live or structured source, run
Semantic Recon by default. This applies to:
A source is a DATA_API, DATABASE, MCP_SERVER, CODEBASE, or remotely
served DATA_FILE.
The source is required by the workflow, regardless of whether reuse or blast
radius has already been proven.
--semantic-recon is retained as a compatibility flag; it no longer opts into the
gate because the gate is automatic. Only a workflow with no external or structured
source may omit Semantic Recon.
Never silently skip the path because probing is inconvenient: if the target qualifies
but access, the blast-radius decision, or the out-of-scope boundary is unavailable,
record verification-blocked and do not generate a direct source client.
When this path applies, invoke /semantic-recon before Phase 2. Its target profile
must name the blast radius and out-of-scope boundary; freeze holdout questions before
discovery; then use the completed contract rather than re-deriving source behavior.
The generated skill must load exactly one registered data_contract_<id>, run its
health check, route requests through validate_query(), preserve its provenance
formatter, and treat a refusal or drift report as a safe stop. Add both success and
refusal cases to the generated evals. Record the contract id, resolved path, target
type, required operations, and freshness check in discovery.json as a
semantic_recon dependency block. Semantic Recon establishes what the source does;
the authorized domain owner still establishes organizational meaning.
See references/pipeline-phases.md for detailed Phase 1 instructions.
Phase 2: Design
Define 4-6 priority analyses covering 80% of use cases. For each: name, objective, inputs, outputs, methodology. Always include a comprehensive report function.
See references/pipeline-phases.md for detailed Phase 2 instructions.
Phase 2 includes an Artifact Opportunity Assessment step. After the
domain is identified, the creator runs scripts/artifact_detector.py on
the description. If the output is visualizable (time series, comparison,
KPIs, or structured rows), one of four bundled React templates is inlined
into the generated SKILL.md along with Claude's artifact emission
protocol. The artifact renders in Claude environments; in other hosts the
component source appears as fenced code and the markdown analysis is
unchanged. See references/phase2-artifact-assessment.md for details.
Override flags — parse the user's prompt for these tokens BEFORE calling the detector:
--no-artifact anywhere in the user's prompt: skip the assessment entirely and generate the skill without any artifact template, exactly as v4 did. Strip the token from the prompt before passing it to Phase 1.
--artifact <name> (where <name> is line-chart, bar-chart, kpi-cards, or data-table): skip the detector and inline the named template directly. If <name> is not one of the four valid names, reject with an error listing the four valid values and stop. Strip the flag and value from the prompt before passing it to Phase 1.
--no-eval anywhere in the user's prompt: skip the Eval Criteria Definition step (below); the generated skill carries no evals/ directory and no run_evals.py. Strip the token from the prompt before passing it to Phase 1.
When neither flag is present, call the detector and let it decide.
Phase 2 also includes an Eval Criteria Definition step. After the use
cases are defined, derive the skill's loss function: 3–6 binary checks (each
graded by a shell command or flagged llm-judge) plus at least 3 golden
cases — seeded from the user's artifacts when available, otherwise synthesized
as input-only pending-first-green cases. Present them for a one-word
thumbs-up. The spec is written in Phase 5 to evals/<name>.eval.md and ships
with the skill as an instant regression test, formatted so
autoresearch-universal consumes it directly (its rule 18). Eval generation is
on by default; --no-eval opts out. See
references/phase2-eval-assessment.md for criteria rules, the golden-case
strategy, the JSON spec format, and the optimize handoff.
Phase 2 also classifies software mutation. If the generated skill creates or
modifies application code, schemas, models, persistence, serialization, caches,
synchronization, migrations, or stateful features, review the affected representation
before designing the implementation. Name the affected structures, invariants, single
sources of truth, invalid states that must be unrepresentable, and allowed state
transitions. Unknown invariants block implementation; do not substitute a generic
checklist. Non-software skills declare that this conditional review does not apply.
Read references/discovery-metadata.md for the schema, then record the result in
discovery.json.
Phase 2 also classifies structured data interfaces. If the generated skill reads
an API, MCP tool/resource, database, structured file, event stream, or schema
registry, establish the data contract before designing its processing logic. Inspect
authoritative documentation and, when safely accessible, one representative sample;
record entities, identifiers, relationships, field semantics, invariants, freshness
and pagination, nullability, and blocking readiness checks. Do not infer undocumented
semantics from field names or treat a successful connection as schema proof. Missing
authority or unresolved ambiguity blocks useful execution. Non-structured workflows
declare that this conditional contract does not apply. Read
references/discovery-metadata.md for the schema.
For a source that qualified for the Phase 1 Semantic Recon path, the completed
Semantic Recon contract is the data contract. Do not replace it with a one-sample
inventory or duplicate its rules in prose; reference its identity and enforce its
validator at runtime.
Phase 2 also classifies organizational semantics. When a correct answer depends
on business definitions, scope, grain, units, time interpretation, or which source
wins, require the human domain owner to approve a versioned semantic contract. Record
ordered source precedence, owner, validity and review dates, exact dependencies, and
the legitimate answer, ask, and refuse_unknown outcomes. The agent may draft and
document this representation but cannot establish authority. Unresolved meaning must
ask the declared clarification or refuse. Skills with no organizational interpretation
declare that this conditional contract does not apply. Read
references/discovery-metadata.md for the schema.
Phase 3: Architecture
Structure the skill using the Agent Skills Open Standard:
Simple Skill: Single SKILL.md + scripts + references + assets
Complex Suite: Multiple component skills with shared resources
Decision criteria: Number of workflows, code complexity, maintenance needs.
See references/architecture-guide.md for decision logic and directory structures.
Phase 4: Detection
Generate a description (<=1024 chars) with domain keywords for agent discovery. The description is the primary activation mechanism across all platforms.
See references/pipeline-phases.md for detailed Phase 4 instructions.
Phase 5: Implementation
Create all files in this order:
Create directory structure
Write SKILL.md — starts with # /skill-name, includes trigger section with invocation examples, spec-compliant frontmatter
Write AGENTS.md — companion instruction file for maximum cross-tool reach (~15 tools read AGENTS.md). Contains skill purpose, activation triggers, usage instructions, and a reference to SKILL.md for full details. Follows the AAIF-governed AGENTS.md format
Implement Python scripts (functional, no placeholders, no TODOs). For a multi-script pipeline, also emit a single scripts/run_pipeline.py orchestrator that runs the steps in order and wires output→input in code — so the agent runs one command instead of sequencing steps from prose. Skip for genuinely interactive/branching skills. If any pipeline step invokes an LLM, follow the LLM-step contract in references/phase5-orchestration.md: model id resolved from --model argv / $EVAL_MODEL env with a pinned default, and runtime-reported usage written to the {output}.usage.json sidecar — so run_evals.py --rollout --model A --model B can price the task per model. See references/phase5-orchestration.md
Write references (detailed documentation the skill loads on demand)
Write assets (templates, configs)
Emit the eval spec (skip if --no-eval): write evals/<name>.eval.md (the binary checks + golden cases derived in Phase 2, one marked "split": "test" as the holdout, plus a judge block with a pinned model and known-bad canary when any criterion is llm-judge) and copy scripts/run_evals_template.py → the generated skill's scripts/run_evals.py. See references/phase2-eval-assessment.md
Also write evals/caliper/<name>.eval.yaml from references/templates/caliper-eval-template.yaml (happy path, edge case, silence probe; asserts mirror the criteria above) so the marketplace operator's agent can measure the skill inside a real agent with team_marketplace.py reliability. See docs/CALIPER.md
7.5. Write discovery.json with the required decision contract (question,
trigger, decision, evidence, and success_measure), plus the real-world
outcome, intended users, input types, output artifacts, use cases, invocation
examples, permissions/systems, typical completion time, declared platform
compatibility, environment discovery/readiness, risk and mutation boundaries,
the conditional software-mutation representation review, the conditional structured
data-interface contract, the conditional governed semantic contract,
and the conditional Semantic Recon dependency block when that path ran,
positive/negative routing tests, and support tier. Read
references/discovery-metadata.md. Never
generate a skill without the five decision-contract fields; do not invent
compatibility certification during creation.
If the user has named a target governed marketplace and its published governance
configuration identifies the responsible owners and required intake state, also
write those exact values as metadata.owners and metadata.approval_status in
SKILL.md. Do not guess an owner, approver, department, or approval status when
no target marketplace is known; leave organizational assignment to intake.
7.6. Copy the ready interview.json into the generated skill root. Run
python3 scripts/structured_interview.py gate <skill>/interview.json immediately
before copying it. A blocked state stops generation; never downgrade a confirmed
field to a proposal or remove conflicts to pass the gate.
Generate both installers deterministically with python3 scripts/render_installers.py <skill-directory>. Never copy the factory's root install.sh or install.ps1; the renderer binds the generated skill name and version into the canonical templates and marks install.sh executable.
8.5. Generate .claude-plugin/plugin.json + marketplace.json from scripts/claude-plugin-template/ (placeholders from frontmatter — makes the skill installable via /plugin marketplace add), and ship the evolution toolkit and local success ledger: copy scripts/evolve_template.py → scripts/evolve.py, scripts/success_ledger.py, plus the staleness/drift/dep-health modules. Also copy scripts/wiki_maintenance_template.py → scripts/wiki_maintenance.py, then run python3 <skill>/scripts/wiki_maintenance.py init. This creates an optional, non-runtime raw/ + wiki/ learning layer: evidence is captured before a maintainer drafts a pattern; only an atomic candidate that passes existing evaluation, security, and pipeline gates may change an active skill. The runtime agent must receive approved skill files only—never wiki/. See references/pipeline-phases.md Steps 6.5–6.6
Write README.md (multi-platform install instructions showing the /plugin marketplace add path for Claude Code and git clone to each tool's native path)
9.5. Build the normalized IR with python3 scripts/skill_graph.py build <skill> --output <skill>/skill.graph.json. This typed artifact/dependency graph is the validation source of truth; the five phases remain its user-facing projection. Read references/skill-graph.md for its schema and invariants.
Run python3 scripts/skill_graph.py run <skill> --jobs 4. It blocks unreachable expected outputs and missing deterministic orchestrators, then runs spec, security, pipeline, and eval-schema gates concurrently with content-addressed caching. All constraints and gates must pass. Record gates_passed with the creation run ID.
Auto-install on the current platform (see below)
Run one safe representative use case using a supplied artifact when possible,
otherwise a local fixture. Never send messages, write production data, purchase,
publish, or trigger another consequential action merely to verify a skill; use a
dry run or sandbox. If safe execution needs missing credentials, data, or authority,
stop with verification-blocked and one exact setup action. Set
ASC_RUN_EVENT=representative_run_passed and ASC_RUN_ID=<creation-run-id> so
the instrumented pipeline records the first result without double-counting it as
an ordinary run.
12.5. Generate VERIFICATION.md from the completed quality evidence. Run
python3 scripts/generate_verification.py <skill> --run-kind representative --environment <current-platform>;
use --run-kind live only after a real external workflow succeeds. The report
is an evidence artifact, not marketing prose: it records gate states, eval counts,
installed environments, the 17-environment compatibility declaration, and a bound
skill version, Git commit, and content fingerprint. Publication must reject a
missing, failed, or stale report.
Report the result using the handoff contract below, including one invocation and
one correction command. Put eval/optimization details behind an advanced label.
Auto-Install After Creation
After the skill passes validation and security scan, install it immediately on the user's current platform. Do not ask the user to run install.sh manually — you are already running inside their environment and can detect their platform.
This path is for skills the factory just built. A skill that came from anywhere else — a download, a colleague, a registry, a repo — must clear --audit first (see above). Auto-install never runs on an unscanned imported skill: the scan is what makes the install safe, and a skill this factory did not produce has not been scanned yet.
Detect the platform by which config directory exists (~/.claude/, ~/.copilot/, .cursor/, ~/.gemini/, and ten more), install to that tool's native path, then symlink into ~/.agents/skills/ so tools reading the universal path find it too. Some platforms need the SKILL.md adapted to their own format.
Read references/distribution-guide.md for the full detection table, the per-platform paths, the confirmation message to show the user, and the install.sh fallback when detection fails.
Share With Your Team (Post-Creation)
After the representative run succeeds and the user can see the result, ask whether
they want to share the skill with their team. Sharing is a separate next step, not
part of first-skill completion.
Corporate users don't know what a registry is, how to git push, or what skill_registry.py does. They just want their colleague to have the same skill. If they say yes, you do all of it: git init, create the remote with whichever CLI is authenticated (gh or glab), tag it agent-skill for org-wide discoverability, and hand back a one-line git clone command they can paste into Slack.
If they say no, that is fine — the skill is installed and working, and they can share later.
After a successful share, record skill_shared; do not record an offer, declined
share, failed publication, recipient identity, repository name, or organization.
Read references/distribution-guide.md for the git/gh/glab procedure, the platform-detection fallback, the shareable one-liner template, team-registry setup, and the update-check flow.
For governed GitHub or GitLab organizations whose primary client is VS Code Copilot Agent
Mode, run python3 scripts/team_marketplace.py instead of using the legacy flat registry. It
creates department namespaces, bundle manifests, CODEOWNERS, provider-native review/release workflows,
schema-v2 quality evidence, and exact version-pinned installs. Runtime
shell access must never be pre-approved in a marketplace skill. Read the governed
marketplace section of references/distribution-guide.md before initializing or
migrating a team repository.
For an organizational readiness decision, run the blind four-role protocol in
docs/ORGANIZATIONAL_ACCEPTANCE.md. Keep administrator, creator, operator, and
consumer contexts and workspaces isolated. Give each role only public documentation
and artifacts legitimately published by the prior role. Any implementation hint or
direct assistance makes that run a failure rather than a successful demonstration.
Completion Handoff Contract
Use exactly one of these states:
verified — gates passed, installation succeeded, and a representative safe run
produced an inspectable result.
verification-blocked — build and gates passed, but a representative run needs
missing credentials, data, or user authority. State the blocker and one exact action.
installed — installation succeeded but the user explicitly declined the run.
failed — a build, gate, installation, or representative run failed. State the
failing check and the next repair action; never use success wording.
For verified, lead with what now works. Then show the result location or short
preview, the exact /skill-name invocation, a compact list of gates passed, and:
python3 <skill>/scripts/evolve.py --correct "what the result got wrong"
Do not lead with file counts, architecture, or internal phase names. Put those under
Advanced details only when useful. After the handoff, ask the user to judge the
result before offering team sharing.
Generated SKILL.md Format
Generated names must end with -skill, match the directory, and use lowercase
kebab-case. Frontmatter carries name, an activation-focused description, license,
author, version, creation/review dates, and any external dependency or schema
expectations. The body starts with # /skill-name, includes trigger examples and a
## Gotchas section, and stays under 500 lines. Read references/pipeline-phases.md
Phase 5 for the maintained template.
Every generated skill carries a ## Gotchas section. It holds the environment-specific facts that defy reasonable assumptions: the field that is a string with commas, the endpoint that returns 200 on failure, the step that must run twice. Sources are the Phase 1 quirks list and every correction made while verifying the skill in Phase 5. None known is a valid value; inventing gotchas to fill the section is not — a fabricated gotcha teaches the agent a false constraint it will then work around. validate.py warns when the section is missing. Full guidance in references/pipeline-phases.md (Phase 5, Step 2).
Critical: Every skill the factory produces must be invocable with /skill-name on any platform. The generated skill is software that gets installed and used — not a document to read.
Architecture Decision
Use a simple skill for one or two related workflows. Use a suite for three or more
genuinely distinct workflows or separate team ownership. Read
references/architecture-guide.md for the full decision framework and layouts.
Cross-Platform Support
Generated skills work across 17 tools in 3 tiers. Every generated skill outputs both SKILL.md (skill definition, ~15 tools) and AGENTS.md (instruction file, ~15 tools) to maximize reach.
Tier 2 — auto-adapted (Cursor .mdc, Windsurf and Trae .md rules, Junie guidelines.md). install.sh rewrites SKILL.md into the native format.
Tier 3 — manual integration (Zed, Augment, Aider, Continue.dev). The user copies the body into the tool's own config file.
scripts/platforms.py is the canonical registry of all 17 platforms and their paths; the installers are checked against it in CI.
Read references/cross-platform-guide.md for the per-platform path tables, install commands, and adaptation rules.
Companion AGENTS.md
Every generated skill also outputs an AGENTS.md alongside SKILL.md, extending reach to tools that prioritize it over SKILL.md (Codex CLI, Augment, Continue.dev, Zed). It carries the skill's purpose, activation triggers, usage, and its ## Gotchas entries in full — those tools never open SKILL.md.
Validation and Security
After generating a skill, run:
Spec validation: Checks frontmatter, naming, structure, line count
Security scan: Checks for hardcoded API keys, .env files, dangerous code patterns, instruction-body prompt injection (override/concealment/exfiltration phrases, hidden unicode, encoded blobs), and undeclared network endpoints in scripts
For factory-created skills, prefer the unified graph gate; the individual commands
above remain useful for focused diagnosis:
python3 scripts/skill_graph.py run path/to/skill/ --jobs 4

Learning & Evolution
Every generated skill ships its own learning loop — the eval harness plus a self-maintenance command:
run_evals.py --rollout runs the skill on its golden inputs and scores real output
--promote captures first-green baselines; later runs are compared against them (regression gate)
--judge grades llm-judge criteria with a judge pinned in the spec (model + temperature); a known-bad canary must fail every criterion or the judge run is invalid
A "split": "test" holdout case is scored only at release, never fed to an optimization loop
evolve.py runs staleness/dependency/drift checks + the rollout in one command; every failure appends its raw evidence to the skill's EVOLUTION.md, which feeds a regenerate pass
evolve.py --correct "<what it got wrong>" turns a correction into a proposed SKILL.md edit, an executable knowledge-retention regression under evals/corrections/, and a versioned patch recommendation in EVOLUTION.md
success_ledger.py records only pseudonymous lifecycle metadata and reports verified creation, reuse, durable activity, correction recovery, and sharing locally. Run python3 scripts/success_ledger.py summary; read references/product-success.md for the privacy boundary and formulas
Tell the user about --correct when you hand over a skill. The deepest expertise in any workflow is never stated up front — people cannot describe a process they run from muscle memory, which is why this factory reads artifacts instead of interviewing. But the same person recognizes a wrong output instantly. --correct is the capture point for that moment, and it is how a skill's ## Gotchas accumulates real knowledge over its life instead of being frozen at whatever could be extracted on day one.
Read references/agentdb-integration.md as a design sketch only — it describes a future episodic learning layer that is NOT implemented; never present it as current behavior.
Quality Standards
Always:
Complete, functional code (no TODOs, no pass)
Detailed docstrings and type hints
Robust error handling
Real content in references (not "see docs")
A ## Gotchas section carrying the environment-specific facts that defy reasonable assumptions
Explicit "run this" / "read this" labels — every scripts/ mention leads with a run command, every references/ mention with a read cue
Configs with real values
Never:
Placeholder code or empty functions
api_key: YOUR_KEY_HERE without env var instructions
SKILL.md over 500 lines
Restating what the model already knows — generic error-handling advice, definitions of standard formats, "validate inputs". Every such line spends context to teach the agent something it already has.
Platform-specific hacks
See references/quality-standards.md for complete standards.
Naming Convention
Every generated skill name must end with -skill. This suffix makes skills instantly discoverable across GitHub and GitLab organizations — teams can search *-skill and find every skill in their org.
Format: {domain}-{objective}-skill
Rules:
Must end with -skill
1-64 characters total, lowercase letters, numbers, and hyphens
Suites: {domain}-suite (suites are not suffixed with -skill — they contain skills)
The -skill suffix also serves as a signal to the agent: when it sees a repo or directory ending in -skill, it knows this is installable, invocable software — not documentation or a regular project.
Gotchas
Generated skills end with -skill; this factory retains the historical
agent-skills-platform name for invocation and installation compatibility.
A representative verification run must use dry-run, sandbox, or local fixtures when
the real workflow has consequential external effects.
