CogZ gives a coding agent persistent memory, contextual retrieval, and continuous cognition about a software repository — all running locally on your machine, no cloud services required.
Works with Claude Code, Cursor, Codex, Gemini CLI, GitHub Copilot, Devin, and any MCP-compatible agent.
Real output from CogZ running on its own codebase:
$ cogz context --mode task "token budget estimation and context pack compression"
Context pack (mode: task)
Query: token budget estimation and context pack compression
Search mode: hybrid
Sections: 91
Token estimate: 8188
Dropped: 6 sections over token budget

## 1. [rule] New expansion channels: emit early, filter before seen-mark, sort deterministically, never displace directs (relevance: 0.5148)
Conventions proven across the sibling and co-change channels:
1. Emit before the generic expansion loops — candidates emitted
later get claimed-and-floored by graph traversal …
2. Apply entity-type/test filters BEFORE `seen.insert` …
…
## 2. [rule] cfg-gated code must be typechecked per-target before release (relevance: 0.4690)
Code behind #[cfg(unix)]/cfg(target_os = ...) is invisible to host
builds, tests, and clippy — a compile error in a cfg'd branch ships
silently until a real target build sees it. The v0.5.0 Windows leg
failure is the canonical example.
## 3. [rule] Degradation must be loud, never silent (relevance: 0.3680)
Every degraded or failed code path must surface a signal …
## 4. [identity] CogZ (relevance: —)
Project: CogZ
## 5. [file] assemble.rs (relevance: 0.6993)
//! Context pack assembly — the tiered-push pipeline.
//! Tier 0 (baseline: identity + top rules) always ships for task and
//! escalation packs …
… 86 more sections …
That's not a text chunk from a vector search. The pack leads with validated rules — one learned from a release failure on this very project — plus the identity baseline and the actual source file, all ranked, traceable, and budgeted.
This repository already contains real dogfooding knowledge — CogZ has been used on its own codebase throughout development. You can clone it, install CogZ, and try the commands above against it directly.
CogZ maintains a project-specific knowledge layer that connects what an agent learns to the code it is working with.
Memory
CogZ stores three kinds of project knowledge:
These are stored as Markdown files with YAML frontmatter, linked to each other and to code entities in the repository. The files are the canonical source of truth — SQLite is a derived index, disposable and rebuildable. Your knowledge is portable, version-controlled, and editable by hand.
Context
Instead of giving an agent everything it knows, CogZ builds scoped context packs for the current situation. A context pack combines relevant rules, observations, knowledge, and code structures — ranked by relevance, traceable through the code graph, and limited by a token budget so the agent gets what matters for the task rather than the entire project history.
Cognition
CogZ periodically consolidates what has been learned: deduplicates entries, detects contradictions, promotes well-supported observations to rules, merges superseded entries, and flags knowledge as stale when the code it references changes.
Linux / macOS / Windows (Git Bash):
# Install
curl -fsSL https://raw.githubusercontent.com/balaianu/CogZ/master/install.sh | bash
# Initialize in a repo (add --configure auto to wire MCP + hooks for detected agents)
cd ~/your-project
cogz init
# Index (downloads models on first run, or use --no-download for FTS-only)
cogz index
# Verify it's working — entity counts, model status, DB stats
cogz status
Windows (PowerShell):
# Install
irm https://raw.githubusercontent.com/balaianu/CogZ/master/install.ps1 | iex
# Initialize in a repo
cd your-project
cogz init
cogz index
See Getting Started for the mental model and a complete walkthrough.
CogZ runs as a stateless MCP server over stdio. Every tool call specifies which repo it targets via a required repo parameter — no Roots, no session state, no fallbacks.
{
"mcpServers": {
"cogz": {
"command": "cogz",
"args": ["mcp-stdio"]
}
}
}
The server exposes 15 tools: create_entity, update_knowledge, verify_knowledge, reject_entity, query_entities, search, get_context, get_status, list_entities, consolidate, capture_event, get_callers, get_impact, find_orphans, suggest_observations.
See MCP Tools for full parameter reference and example responses. See Agent Setup for per-agent config files, hook formats, and verified capability notes for all six supported agents — or just run cogz configure auto.
Hooks capture lifecycle events and inject context packs into agent sessions. CogZ's binary is the hook handler — no wrapper scripts needed.
{
"hooks": {
"SessionStart": [{
"matcher": "",
"hooks": [{
"type": "command",
"command": "cogz capture-event session_start --hook-json",
"timeout": 15
}]
}]
}
}
See Hooks for all 7 event types and per-agent wiring guides.
Normal operation is automatic: hooks fire on lifecycle events, the agent drives CogZ through MCP. The CLI is not needed for day-to-day use — it's available for setup, manual exploration, and automation if you want or need it.
See CLI Reference for all flags and options.
Works without ONNX Runtime or model downloads. All hooks, FTS search, context packs, consolidation, doctor, and prune are functional. Vector search, embedding-based dedup, and contradiction detection are not available.
Full functionality including vector search, semantic dedup, and NLI contradiction detection. Models auto-download on first use and auto-unload after 5 min idle (RAM drops back to ~11 MB). See Evaluations for the full resource consumption profile.
CogZ ships a reproducible suite (benchmark/) run on pinned public corpora — httpx, cobra, clap, each injected with memory seeds mined from its real git history — plus this repository's own .cogz corpus. Seeded ground truth:
Channel ablations on commit queries: removing graph expansion costs 3–15pt recall@20; FTS-only mode is competitive on commit-intent queries (0.34–0.47 R@20 vs hybrid's 0.31–0.47) — the vector channel's lift concentrates on semantic queries while expansion dilutes under the row cap (tracked as the top ranking issue). Context packs keep 0.49–0.89 expected-entity recall at the default 8K budget. Reruns are byte-identical. Full methodology, per-phase numbers, and the raw artifacts: benchmark/README.md.
What using it buys (measured): in a 14-task agent replay, the seeded-knowledge arm finished ~2x faster than bare (871s vs 1748s average) and completed more runs (14/14 vs 10/14) at equal correctness. Consolidation machinery is precise: dedup precision/recall 1.0, NLI contradiction detection 4/4 with zero false alarms, drift marking exact.
Honest limits: top-5 precision is weak on mixed corpora (P@5 <= 0.20; code entities outrank knowledge at the top of the ranking), commit-intent queries reach 0.31–0.53 recall@20, adjacent-domain negative queries still leak confident hits (silence-gate clean rate 0.47–0.73 across corpora), and at n=14 tasks there is no measurable task-correctness lift yet.
See Architecture for the full system design.
macOS Intel is not supported because Microsoft dropped ONNX Runtime macOS Intel binaries after v1.22. Intel Mac users can run the arm64 binary under Rosetta 2 (with a compatible ORT build) or use cargo install cogz for FTS-only mode.
Windows 10+ is required (bsdtar is bundled since build 17063, needed for ONNX Runtime auto-extraction).
Cross-platform team collaboration is supported: code entity UUIDs use forward-slash path normalization so the same source file produces the same entity ID on all platforms.
