Mine the architecture rules your repo already enforces, with the evidence attached.

Every codebase has unwritten rules. "Pages never talk to the database directly." "Shared code never reaches back into the app." Nobody wrote them down, but the code follows them, until one day someone (or an AI assistant) breaks one without noticing.
Archprint reads a TypeScript project, finds the rules its code already follows, and shows you the proof for each one: how many files follow it, which files break it, and how sure it is. The rules you trust become automatic checks in the tools your team already runs, so a break is caught the next time lint runs (in your editor, a pre-commit hook or CI), not weeks later in review.
Think of it as a building inspector who surveys the house first and writes down how it was actually built, instead of handing you a rulebook from somewhere else.
init, connected with wire, and removed with eject.archprint check flags only the rule breaks a pull request introduces, inline on GitHub,
never the existing backlog.Your CLAUDE.md is guidance. Your lint rules are enforcement. Archprint closes the gap by generating the
enforcement from patterns your codebase already demonstrates, so you adopt rules you can trust instead of
authoring them by hand.
The recordings below use archprint-demo, a small Next.js API whose routes reach the database only through a service layer.
1. Find the rules your code already follows. Each rule comes with its evidence.
2. See why one rule is trusted. The confidence check, step by step.
3. Turn the rules on, watch a break get caught, and remove it all again. Archprint writes its files, adds one
line to your ESLint config, lint flags a route that imports the database directly, and eject restores your
project exactly.
Try it yourself, nothing to install: open the demo in StackBlitz. The scan runs as soon as it opens, and the demo's README walks through enforcing a rule in ESLint, breaking it, and asking for the rules over MCP.
AI coding agents can ask Archprint for a project's rules through MCP, an open standard that lets agents use outside tools. You ask in plain words; the agent calls Archprint on its own and answers with the evidence. Archprint only reports. Enforcement still runs in your linter.
Claude Code lists the rules with what is enforced and what is held for review, then adds a route and checks its own change with archprint before it reports back:
Cursor works the same way. In these recordings Cursor was set to Grok 4.7, not Claude. In the desktop app's chat, its agent called Archprint's scan tool on its own; this screenshot shows the tool result and the answer:
In the terminal (cursor-agent), it does the same: lists the rules, then adds the route and checks it with
archprint_check:
We asked Claude Code (Opus 5.5) "What architecture rules does this repo already follow?" on the demo app (70 files), five runs each way. Median [range]:
What the answers showed:
lib/services/.lib/db.ts
reads process.env outside the config layer). No run without it noticed that.Read these numbers with care: about 50k of the tokens read in both columns are Claude Code's own system prompt, and this is one small repo; larger ones are not measured yet. Method, harness and every answer.
Setup for Claude Desktop, Claude Code, Cursor and other clients is in MCP setup.
Requires Node 20 or newer. Run these in a folder with a tsconfig.json. In a monorepo, scan and recommend
also accept the root and cover every app, while init and generate work on one app at a time (for example
apps/web); at a root with several apps they stop, list the apps, and ask you to rerun with one.
# 1. See the rules your code already follows, with the evidence. Changes nothing.
npx archprint scan .
# 2. Ask why one rule is trusted (use a rule label from the scan)
npx archprint explain AP-001 .
# 3. Set up enforcement for the rules your code already follows cleanly,
# and record what to review or adopt next in .archprint/config.json
npx archprint init .
# 4. Connect the generated rules to your ESLint / dependency-cruiser config (one managed line)
npx archprint wire
# 5. Run your linter as usual. Your code passes today; a new import that breaks a rule fails.
npx eslint .
# To undo everything, exactly:
npx archprint eject
See it catch something. After step 4, break a rule on purpose: for example, make a route file import your database client directly, then run your linter. That is the whole loop the demo walks through in the browser.
To keep it in the project instead of using npx: npm install --save-dev archprint.
More commands for a deliberate, step-by-step setup:
# Inspect the evidence behind one rule
archprint explain AP-002 apps/web
# Write the auto-trusted (mechanical) rules to .archprint/, only for the linters your repo uses.
# Structural-inference rules are held for review; add --include-structural to emit them too.
archprint generate apps/web
# Confirm the generated rules pass on your repo before wiring
archprint generate apps/web --check
# Generate a single rule by id after reviewing it (including a SUGGEST rule)
archprint generate apps/web --rule AP-001
# Adopt only the rules you choose, including reviewed layer boundaries
archprint generate apps/web --include-structural --rules AP-002,no-utils-to-app
# Recommend a rule set from the evidence and the detected stack (fresh repos too)
archprint recommend apps/web
# Upgrading from 0.5.x? Move an older archprint-rules/ setup to the .archprint layout

Archprint is deliberately cautious: one wrong rule hurts more than no rule. Every candidate rule passes two checks before it is turned on for you.
1. Is there enough evidence? Seeing 5 of 5 files follow a pattern is not proof; 40 of 40 is. Archprint scores each rule with a Wilson score lower bound, a standard statistical measure that combines how often the rule holds with how many files it was checked on. Each rule lands in one of three groups:
2. Could the rule itself be wrong? A rule can pass the numbers and still be wrong if Archprint guessed a
folder's purpose incorrectly. So only the mechanical families, which rest on unambiguous signals, are trusted
without review: forbidden imports (AP-001, AP-002), circular dependencies, test isolation, import style, console
isolation, and public-API barrels. An adversarial correctness audit (three rounds over four real repositories)
found zero false positives in these every round. All of them except circular dependencies are written as lint
rules; a cycle-free codebase with enough files for the gate adopts "no circular dependencies", which
archprint check enforces on each pull request (cycles need the whole import graph, so there is no lint rule for
them).
The structural families infer a "layer" or "role" from paths, which can be wrong (layer and role boundaries,
UI/data separation, entry purity, server/client, feature-slice and app isolation, env access, workspace package
API, stories isolation). Dependency hygiene, whose enforcement can over-flag, and dependency declaration are held
back too. All of these are held for your review by default and written as enforcement only with
--include-structural, regardless of their statistical score, until they earn the same clean record. Nothing
that could be wrong is enforced without you opting in.
Generated rules are green by construction: each one lets through the few known exception files it was inferred
from, so adopting it keeps your lint green while new violations are still caught, and a self-consistency check
refuses to write a rule whose evidence does not hold together. To run the generated rules against your code before
connecting them, use archprint generate --check.
Ships as: Auto = turned on as enforcement (mechanical families). Review = held for your review by
default; emit with --include-structural. Check = enforced by archprint check on each pull request. Report =
shown only, never enforced.
Archprint recognizes the stack (Next.js, Nest, SvelteKit, Nuxt, Remix) and classifies UI components across React
(.tsx), Angular (.component.ts, .directive.ts), and Vue and Svelte single-file components (it reads the
<script> block of .vue/.svelte files), so the component-aware rules apply regardless of framework.
recommend (and init) sort every rule family into tiers: rules your code already follows (enforce now), rules
your code follows that Archprint reports but does not write, rules with thin
evidence (review and adopt), and rules that comparable repos commonly follow but yours does not yet (adopt from day
one). Each recommendation carries the share of comparable repos (your detected stack, else
overall) that already enforce that rule, mined from a census of tens of thousands of public TypeScript
repositories. So even a fresh repo, with little code to learn from, gets a stack-aware baseline backed by what the
ecosystem actually does rather than hand-picked defaults.
archprint generate (and init) writes .archprint/config.json plus one file for each linter your repo already
runs that has rules to enforce. A typical ESLint project gets two files, config.json and eslint.mjs; a repo
whose dependency-cruiser rules are adopted too gets a third. archprint detects ESLint and dependency-cruiser, so
you are never left with config for a tool you do not have. --emit <eslint|dependency-cruiser|all> forces the
format.
.archprint/config.json (always): the exact definition of each rule you adopted, with the
evidence recorded at adoption and the resolution mode it was generated in (archprint check reads it, so a check
never re-infers a rule), the exceptions you allowed with a reason, what is enforced, followed but only reported,
held for review, and worth adopting, and the list of managed outputs eject removes..archprint/eslint.mjs (when ESLint is present): one self-contained ESLint flat-config file that inlines
every inferred ESLint rule (marker-based forbidden imports, no-restricted-imports import-style boundaries,
console isolation, and, when you include structural rules and do not use dependency-cruiser, layer boundaries,
undeclared (phantom) dependencies, the server/client boundary, package internals and entry purity)
and needs no extra plugins: it adds rules to your existing ESLint setup, which already parses your TypeScript.
So you can commit it, publish it, or hand it to another repo and adopt it in one line
(import archprint from './.archprint/eslint.mjs'). Layer boundaries are the exception: they find your app
relative to the file, so they only apply where it was generated. It self-ignores **/.archprint/**. The
forbidden-import (AP-) rules and those structural rules ship as a generated local eslint plugin inside it, so
wiring the eslint config enforces them too, no extra install..archprint/dependency-cruiser.json (when dependency-cruiser is present): one forbidden ruleset with the
mechanical boundaries (public-API deep-import, test-isolation); the review-held ones (layer, role-layering,
feature-slice, app-isolation, entry-purity, dependency-internals, phantom deps, server/client) are added only with
--include-structural, after you review them.README.md summarizing what is enforced now, followed but only reported, held for
review, and worth adopting (written by init, or generate --readme), plus a managed .prettierignore entry so
the generated files stay out of your formatter.--expand additionally writes the granular artifacts inside .archprint/: the per-family ESLint and
dependency-cruiser JSON, per-rule cards (.md) with passing and failing fixtures, the eslint-plugin-boundaries
element-types config, ts-arch tests, and the Mermaid and Graphviz DOT layer graph.
Staying in sync, and leaving cleanly. Re-running generate (or init) refreshes .archprint/ and drops any
rule the evidence no longer supports, so the output never drifts from the code. wire inserts a single managed
reference into each enforcement tool your repo uses (a flat eslint config, a .dependency-cruiser.json), one that
survives those regenerations; for a config it cannot safely edit (a JS dependency-cruiser config, say), it prints
the exact snippet to paste. eject removes Archprint's files and every wired reference, restoring each config
exactly. generate --check runs the generated ESLint rules against your repo and reports whether they pass, so you
can confirm before wiring. Upgrading from 0.5.x? archprint migrate moves an older archprint-rules/ setup to
this layout and rewires your configs in place.
archprint check reports only the violations a change introduces, compared with a base branch, for the rules
your team adopted with init or generate. The existing backlog never shows up, and every finding carries its
evidence. It works in any CI, and on GitHub it shows each finding inline on the pull request
(see it on a demo pull request).
On GitHub, use the archprint check Action (on the GitHub Marketplace):
# .github/workflows/archprint.yml
name: archprint
on: pull_request
permissions:
contents: read
jobs:
check:
runs-on: ubuntu-latest
steps:
- uses: Tommkruix/archprint-action@v1
It checks out the pull request itself, so it needs no checkout step. The same check in plain steps, without the Action:
# .github/workflows/archprint.yml
name: archprint
on: pull_request
permissions:
contents: read
jobs:
check:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v5
with:
ref: ${{ github.event.pull_request.head.sha }}
fetch-depth: 0
- uses: actions/setup-node@v5
with:
node-version: 22
- run: npm ci
- run: npx archprint check --base ${{ github.event.pull_request.base.sha }} --format github
Warning by default. Add --fail-on new (or the Action's fail-on: new) to fail the job on a new
violation, then mark the job a required status check in your branch protection so a pull request that adds one
can't merge.
Only adopted rules. check reads the adopted rules in .archprint/config.json, written by init and
generate, and checks only the rules recorded there: the mechanical rules, plus layer boundaries once you adopt
them with --include-structural. Rules adopted in the same
pull request are listed but never counted against it.
Imports that resolve to nothing are TypeScript's job. Run tsc --noEmit in CI, or rely on the type check
next build runs by default: it reports a missing module (TS2307) with your project's own module resolution.
Archprint does not generate this rule, and on a TypeScript app import/no-unresolved or dependency-cruiser's
not-to-unresolvable tend to report false errors on paths aliases, package exports and bundler suffixes such
as ?raw.
A justified exception needs a reason. When a file has a real reason to break a rule, record it:
npx archprint allow AP-001 app/api/health/route.ts --reason "Health check queries the database directly".
It goes in the allowed list of .archprint/config.json, check stops counting it and lists it with its reason
in the pull request, and the next archprint generate stops the generated rules flagging it. An entry without a reason is
rejected, and an entry the code no longer needs is pointed out. Rules enforced through dependency-cruiser (public
API) are not covered on that side yet.
Removing rules is never silent. If a pull request deletes .archprint/config.json, or the rules in it,
that the base branch has, check warns and lists every rule that stops being checked. It does not
fail the job, because dropping a rule can be a deliberate team decision. To make that decision need a reviewer,
add a CODEOWNERS
entry and turn on "Require review from Code Owners" in branch protection:
/.archprint/ @your-team
/.github/workflows/ @your-team
Upgrading: from 0.8.x or earlier, run archprint generate once to record the adopted rules. Until you do,
check posts a notice that it did not run and exits 0. Setups from 0.9.0 to 0.11.x keep working as they are:
check still reads their rules.json and allow.json, and the next generate moves both into config.json.
Other CI systems: --format json gives version-keyed output, and the exit code is the contract: 0 ok, 1
new violations with --fail-on new, 2 the CI setup is wrong (for example a shallow clone without the base
commit). Check out the full history (fetch-depth: 0 or your CI's equivalent).
Safe on pull requests from forks. It needs only read access, uses no secrets, and never runs your code.
archprint mcp runs Archprint as an MCP server over stdio, so an agent can ask
what architecture rules your repo already follows, with the evidence, before it writes code. It exposes four
read-only tools: archprint_scan, archprint_recommend, archprint_explain, and archprint_check. Each rule
comes back stated in plain words, with its evidence, the files that break it, and whether archprint enforces it,
holds it for review, or only reports it. archprint_explain takes any rule label from the scan (for example
AP-002 or env-access). archprint_check reports the adopted rules the agent's current change breaks,
uncommitted edits included, so it can fix them before it finishes. Point Claude Desktop, Claude Code, Cursor, or
any MCP client at it:
{
"mcpServers": {
"archprint": { "command": "npx", "args": ["-y", "archprint", "mcp"] }
}
}
Things to ask your agent. You do not name the tools; the agent picks them:
Your code stays on your machine. This default is a local server: it reads your local checkout, so it is the one to use for private code, and your source never leaves your machine, whichever git host you use.
If the server will not start. If the client says the server failed to start or npx was not found, it cannot
see your shell's PATH. Desktop apps opened from the Dock or Start menu do not load it, which is common when Node
comes from nvm or Homebrew. A full path to npx alone is not enough, because npx itself needs node on the
PATH. Point both at the folder that dirname "$(which node)" prints, for example /opt/homebrew/bin:
{
"mcpServers": {
"archprint": {
"command": "/opt/homebrew/bin/npx",
"args": ["-y", "archprint", "mcp"],
"env": { "PATH": "/opt/homebrew/bin:/usr/bin:/bin" }
}
}
}
Starting the editor from a terminal also works, because it then inherits your shell's PATH.
One-line installs. In Claude Code:
claude mcp add archprint -- npx -y archprint mcp
In Cursor, put the JSON above in .cursor/mcp.json in your project (or ~/.cursor/mcp.json for every project),
then enable archprint under Settings > MCP.
Scanning a public repo by URL. archprint mcp --http runs a remote server instead. It clones the repo shallow
to a temp dir, runs the same read-only analysis, returns the result, and deletes the clone (only public
github.com, gitlab.com, and bitbucket.org URLs; nothing is written or kept). The tools then take a repo URL
(and an optional ref). It listens on 0.0.0.0:8848/mcp by default (set --host 127.0.0.1 to keep it to your
own machine, or --port/$PORT to change the port) and answers health checks at /health (use this one on Cloud
Run, which reserves /healthz) and /healthz. Every request clones and scans, so a server anyone can reach spends
compute on anyone's behalf: keep it behind authentication, such as Cloud Run's IAM, unless you accept that cost.
The tools are read-only (they never write to the repo); use the CLI's generate/wire to actually emit and
enforce rules.
Established TypeScript tools (dependency-cruiser, eslint-plugin-boundaries, Nx, Sheriff, ts-arch) all enforce architecture rules you write by hand. Archprint infers them from the actual import graph and gates each one on statistical evidence before proposing it. It then emits into those tools' formats, so it complements your stack rather than replacing it.
Verified against each tool's documentation (TypeScript ecosystem). The two columns that matter are the ones no other TypeScript tool fills:
Honest caveat: in other ecosystems, Tach (Python) and ArchLint (Java) do auto-infer module boundaries, so Archprint's specific niche is auto-inference plus statistical evidence gating in the TypeScript ecosystem. Archprint also overlaps in detection with dependency-cruiser (cycles, orphans, reachability) and knip (dead code); rather than compete, it writes the rules it generates in those tools' formats.
archprint init [path]: zero-config setup. Detects the stack, enforces the rules the code already follows,
and writes .archprint/ plus a managed README section. Options: --expand, --include-structural,
--out <dir>, --fast, --force.archprint scan [path]: reports the rules the repo already follows, with evidence. Changes nothing.
--deep resolves through barrels and aliases.archprint explain <id> [path]: shows the gate breakdown for one rule, with a codeframe per exception plus
how to fix, when not to use it, and how to enforce it.archprint recommend [path]: recommends a rule set from the repo's evidence and detected stack (works on a
fresh repo too), and names the installed tool that will enforce each rule it can write.archprint generate [path]: writes the auto-trusted mechanical rules to .archprint/ for the linters your
repo uses; structural rules are held for review. --emit <eslint|dependency-cruiser|all> forces the format,
--only <family> and --rules <ids> narrow the output (--rules keeps only the rules it names, such as
AP-002, import-style or the layer rule no-lib-to-app), --check runs the generated rules against your repo,
--readme adds the README section, --expand also writes the per-family files, cards, fixtures and graph, and
--rule <id> emits one reviewed rule. Also --include-structural, --no-graph, --out <dir>, --fast.archprint check [path]: reports the violations of your adopted rules that a change introduces, compared
with --base <branch or commit>. Warning only unless --fail-on new. --format text|json|github,
--out <dir>. See Use in CI.archprint allow <rule> <file> --reason "...": accepts one adopted rule being broken in one file, with a
reason, recorded in .archprint/config.json. check stops counting it and lists it in the pull request;
generate stops the generated rules flagging it. --remove takes it back out.archprint wire: references the generated rules from the enforcement tools your repo uses (flat eslint
config, .dependency-cruiser.json) through a managed, reversible reference. --out <dir>, --dry-run.archprint eject: removes Archprint's generated files, its config, the managed README section, and any
wired references, restoring each config exactly. --out <dir>, --dry-run.archprint migrate (alias upgrade): moves an older archprint-rules/ setup to the .archprint/ layout
and rewires your configs in place. --dry-run.archprint mcp: runs Archprint as an MCP server so Claude, Cursor, and other agents can call the read-only
scan, recommend, explain, and check tools. Serves over stdio by default; --http runs a remote server
that scans a public repo by URL (scan, recommend, and explain).scan --json, recommend --json and check --format json emit stable, version-keyed JSON for scripting. Exit
codes are the contract: 0 on success, 1 on error (for check: new violations with --fail-on new), 2 for a
check that could not run because of the CI setup.
A real scan of inbox-zero (apps/web at commit 11281be, 2,232 TypeScript
files), trimmed to the first rules of each section:
Scanned 2,232 TypeScript files
Workspace aliases: 18 resolved
GENERATED RULES
AP-002 no-ui-layer-in-server-entry confidence 97%
A request handler must not import UI components.
Evidence: 216 of 217 files it applies to follow it (99.5%)
Exceptions: 1
LAYER BOUNDARIES (review before enforcing)
utils !-> app layer boundary confidence 99%
Evidence: 650/653 utils files conform (99.5%); 451 app file(s) depend on utils
Exceptions: 3
utils !-> components layer boundary confidence 99%
Evidence: 650/653 utils files conform (99.5%); 160 components file(s) depend on utils
Exceptions: 3
hooks !-> app layer boundary confidence 94%
Evidence: 65/65 hooks files conform (100%); 121 app file(s) depend on hooks
AP-002 is a mechanical family, so it auto-generates as enforcement. The layer boundaries are inferred, so they
are shown for review, not written as enforcement unless you pass --include-structural. Every number is measured
from the import graph, not estimated.
A layer boundary is held for review because a folder name can be misread as a layer. Once you have read the
evidence, adopt the boundaries you agree with by id: utils !-> app becomes the rule no-utils-to-app.
# 1. Read the boundaries and their evidence
archprint scan apps/web
# 2. Write the rules you chose: AP-002 plus two of the boundaries above
archprint generate apps/web --include-structural --rules AP-002,no-utils-to-app,no-hooks-to-app
# 3. Reference the generated rules from your ESLint config (once)
archprint wire
Without dependency-cruiser, each boundary becomes an ESLint rule in .archprint/eslint.mjs, such as
archprint/no-utils-to-app, with no extra plugin; with dependency-cruiser, it goes there instead. The rule
exempts the files that already break the boundary, so your lint stays green, and it catches a new import across
the boundary, by relative path or alias. archprint check reports a new break in a pull request, and
archprint allow records a justified exception. --rules keeps only the rules it names, so list every rule you
want in the same run. If your CI pins archprint (for example the GitHub Action's archprint-version), use 0.13.0
or later there first. The rules reference
says exactly which imports and files the rule reads.
Fast and deep modes. scan defaults to a fast specifier-level pass (no type checker). generate defaults
to a deep pass that resolves through barrels and workspace aliases, since generation is the commitment point.
Structural analysis (cycles, orphans, reachability, public-API) always uses the fast graph: it is faithful to deep
resolution for those, and public-API detection in fact requires it (deep resolution would resolve through a barrel
and erase the barrel-versus-deep signal).
Determinism. The same repo at the same version produces the same output. Analysis is pure and sorted; there is no randomness, and the analysis engine is pinned to an exact version.
Published on npm and safe to run on your real repo. Every rule is review-gated by default, reversible in one
command (archprint eject), and deterministic, and generated rules are green by construction on the code they
were inferred from.
scan over 92,861 public
TypeScript repositories with no crashes; 494 (0.5%) could not be fetched or timed out, most of them deleted or very
large repositories. The full workflow (init, check, allow, generate, check, wire, eject) ran on a
2,019-repo stratified sample: it found one bug, exceptions in route folders like Next.js [id], fixed in 0.12.3, and
all 2,012 repositories it ran on came back exactly as they were after eject.scan and recommend, check for pull requests, and auto-enforcement of the
mechanical families, with a self-consistency check at generate time, an init scaffolder for fresh repos, and
framework coverage across React, Angular, Vue, and Svelte. The engine (twenty detectors, the confidence gate, and
emitters for a self-contained ESLint file, dependency-cruiser, ts-arch, and the layer graph) is in place and
tested..archprint/ layout arrived in 0.6.0, and
archprint migrate upgrades an older setup in place.A companion benchmark, AgentRuleBench, measures the guidance-vs-enforcement question directly (a pre-registered, honest null result on the boundary it tested).
Full docs live at tommkruix.github.io/archprint and in
docs/: getting started, concepts (the confidence
gate, mechanical vs. structural, fast vs. deep, the generate/wire/eject lifecycle), and the
rule-family reference (what each rule detects, how it ships, and when not to use it).
See CONTRIBUTING.md. The project lints, type checks, and tests itself; every change keeps coverage above its thresholds and ships a changeset.
