What is skills AGENTS.md?

A project instruction file template for documenting commands, architecture boundaries, constraints, and logging expectations. It gives contributors a shared reference for how to work in a repository.

Use it to define smoke, check, test, and CI commands; record project entry points and runtimes; document architecture rules; and set expectations for parsing, typing, responsibilities, and run identifiers.

It reduces uncertainty about which checks to run and where code or documentation should belong. It also encourages consistent validation and structured logs.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00402	$0.00402
Opus 5.5	$0.00161	$0.00161
Sonnet 5.5	$0.00080	$0.00080
Haiku 4.5	$0.00040	$0.00040

Security

Grade A, and why

skills AGENTS.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 1mo 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.

Project Overview

Project: <project-name>
Primary runtime(s): <runtime>
Main entrypoint(s): <entrypoints>

Harness Commands

Run from repository root:

Goal	Command
Fast sanity check	`make smoke`
Static checks	`make check`
Full test suite	`make test`
CI-equivalent local run	`make ci`

Constraints And Guardrails

Prefer deterministic scripts over interactive/manual steps.
Keep command names stable (smoke, check, test, ci).
Update docs and scripts in the same change when workflow behavior changes.
Avoid side effects outside the repo unless explicitly required.

Architecture Boundaries

Parse and validate external data at boundaries.
Keep internal data models typed and normalized.
Keep each module focused on one responsibility.
Document boundary ownership in docs/ARCHITECTURE.md.

Observability Expectations

Include trace_id and run_id in long-running workflow logs.
Emit structured event names for major transitions (start, step, success, failure).
Keep event fields stable for querying and alerting.
Maintain field definitions in docs/OBSERVABILITY.md.

Execution Plans

For tasks expected to exceed ~30 minutes, create/update PLANS.md before coding.
Track scope, constraints, milestones, and verification steps.
Update status checkpoints during execution and after major decisions.

Static Analysis And Quality Gates

Run make check before make test.
Run make ci before pushing large refactors.
Treat lint/type failures as blocking.

Entropy Management

Remove stale scripts/docs quickly.
Keep templates and real workflows in sync.
Run periodic harness audits:
- scripts/audit_harness.sh .

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.
