agents

A collection of rules that defines the project’s identity, required practices, commands, and navigation instructions. It is loaded automatically and points agents to the project’s broader context.

In plain words
What is it for?
Reading project instructions, following required quality checks, updating project state after tasks, and refreshing the code index when work is complete.
Why use it?
It gives agents a shared starting point and records required checks before work is handed over.

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.

Made for: Cursor.

Per session 30 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 387 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

agents 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 2d 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.

What it actually says

Metagit

After Every Task

After completing any task: update .mex/ROUTER.md project state and any .mex/ files that are now out of date. If no pattern existed for the task you just completed, create one in .mex/patterns/.

Before you tell the user the work is done — if this conversation introduced or edited project files under this repo — run task qa:prepush from the repository root (scripts/prepush-gate.py via scripts/prepush-gate.zsh). Fix failures and re-run until green. Only skip when the task was strictly read-only (no writes) or the user explicitly waived the QA gate in this thread.

Last step before hand-off — after QA passes (or when QA was skipped for read-only work), run task gitnexus:analyze from the repository root so the GitNexus index stays current for MCP tools and agents.

Commands (minimum)

  • QA gate before hand-off / “work complete”: task qa:prepush (format, lint, tests, integration tests, context-aware pip-audit/bandit; optional gitleaks when installed)
  • GitNexus index refresh (always last): task gitnexus:analyze
  • Full unit tests only: task test

At the start of every session, read .mex/ROUTER.md before doing anything else. For full project context, patterns, and task guidance — everything is there. Use the GitNexus MCP tools to understand code, assess impact, and navigate safely.

Changes

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.

agents is a cursor rule published in the GitHub repository metagit-ai/metagit-cli (2 stars, last pushed 4d ago), licensed MIT. It adds 30 tokens to every session and 387 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
