agents

agents is an instructions file for GitHub Copilot from metagit-ai/metagit-cli. It costs 408 tokens per session, scanned A, original, MIT.

A set of project instructions that tells an agent where to find the project’s identity, rules, commands, and broader context. It points the agent to a router file that serves as the starting map for the project.

In plain words
What is it for?
Use it at the start of a coding session to load project context, then to record changes, update reusable runbooks, and log important decisions.
Why use it?
It reduces the risk of making changes without knowing the project’s conventions or required checks. It also defines what should be recorded after meaningful work.

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 4d 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 This Is

Non-Negotiables

Commands

After Every Task

After meaningful work, run GROW:

  • Ground: what changed in reality?
  • Record: update .mex/ROUTER.md and relevant .mex/context/ files
  • Orient: create or update a .mex/patterns/ runbook if this can recur
  • Write: bump last_updated on changed scaffold files and run mex log when rationale matters

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.

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.
