mache CLAUDE.md

mache CLAUDE.md is an instructions file for coding agents from agentic-research/mache. It costs 1,914 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for Mache, a Go project that organizes structured data such as JSON, SQLite databases, and source code.

In plain words
What is it for?
Use them when developing Mache, especially for running tests, linting, building the program, or understanding its data and graph structure.
Why use it?
They provide the project's build, test, formatting, and validation commands so changes can be checked consistently.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mache CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Build & Test Commands

All commands use Task.

task build          # Build binary + codesign (macOS)
task test           # Run all tests (go test -v ./...)
task lint           # golangci-lint run ./...
task fmt            # gofumpt -w -extra .
task vet            # go vet ./...
task check          # full CI-equivalent: fmt + vet + lint + parity + test + validate + docs/actions/yaml lints + smells + gates:preflight + server-json
task validate       # SQLite ingestion tests only
task test-go-schema # Self-hosting smoke test (ingests mache's own source)
task tidy           # go mod tidy

Run a single test: task test -- -run TestName or go test -v -run TestName ./graph/.

Integration tests require real SQLite databases and are gated behind env vars (MACHE_TEST_KEV_DB, MACHE_TEST_NVD_DB) — they skip automatically when unset.

Architecture

Mache projects structured data (JSON, SQLite, source code) as a filesystem driven by declarative JSON schemas.

Three Presentation Paths

.db files  →  SQLiteGraph (zero-copy, lazy scan, direct SQL)  →  GraphFS (NFS) or MCP
other files →  Engine (walkers + loaders)  →  MemoryStore       →  GraphFS (NFS) or MCP
any source →  Engine → MemoryStore/SQLiteGraph                 →  MCP (Streamable HTTP or stdio)

The .db path (SQLiteGraph + internal/template) is pure Go — no CGO, no tree-sitter. The source code path (Engine + SitterWalker) requires CGO for tree-sitter grammars. When ley-line pre-parses source into .db files with _ast tables, ASTWalker replaces SitterWalker and the entire pipeline is pure Go.

The mache serve command exposes the graph as MCP tools without mounting a filesystem. Two transports: Streamable HTTP (--http :PORT, default, always-on) and stdio (--stdio, subprocess mode). HTTP mode uses stateful sessions — each client gets its own session ID mapped to the projected graph. Prefer HTTP over stdio to share one daemon across all sessions (avoids per-client FD leaks).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
