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.

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 | $0.00078 | $0.00560 |
| Opus 5.5 | $0.00031 | $0.00224 |
| Sonnet 5.5 | $0.00016 | $0.00112 |
| Haiku 4.5 | $0.00008 | $0.00056 |
Grade A, and why
compose-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.
What it actually says
Compose AGENTS.md Skill
Help the user create an AGENTS.md for their project.
Step 1 — Understand the Project
Ask (if not already known):
- What language(s) does the project use?
- What architectural pattern (hexagonal, microservices, BFF, monolith)?
- What is the primary purpose of the project?
- Which AI vendors are used on this project?
Step 2 — Recommend a Profile
Check just list-profiles to show available profiles.
Match the user's answers to an existing profile. If a match exists:
just compose {profile-name} {/path/to/target-project}
If no profile matches closely enough, offer to: a) Compose from individual fragments (guided selection) b) Create a new profile for this project type
Step 3 — Fragment Selection (if no profile matches)
Guide the user through selecting fragments:
Base fragments (always recommended):
git-conventions— always includesecurity— always includecode-review— include if team does code reviewstesting-philosophy— include if testing standards matterdocumentation— include if docs standards matter
Language: pick from agents/languages/
Architecture: pick from agents/architecture/
Practices: pick from agents/practices/
Domain: pick from agents/domains/ if a match exists
Step 4 — Compose and Deploy
Run the compose and vendor-gen commands:
just compose {profile-or-custom} {target-path}
just vendor-gen {target-path}
Step 5 — Verify
Open {target-path}/AGENTS.md with the user and confirm:
- The content accurately represents the project's standards
- Build/test/lint commands are correct
- No placeholder tokens (
{{TOKEN}}) remain unfilled
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.

compose-agents-md is a skill published in the GitHub repository soulcodex/agentic (10 stars, last pushed 2d ago), licensed MIT. It adds 78 tokens to every session and 560 once invoked, about $0.0003 per session on Opus 5.5. 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.

skill-navigator
A skill that recommends which already-installed local agent skill matches a described task. It uses the machine's skill catalogue and does not perform the task itself.
repo-hygiene
Use when the scheduled repo-hygiene workflow runs from GitHub Actions (or an operator dry-run) to scan the repository for small, certain docs/test/code hygiene issues and fix them as one batched branch.
opencli-usage
Discover and invoke OpenCLI capabilities for websites and Chrome. Find commands, inspect schemas, interpret results and choose browser or adapter tools.
test-failure-explorer
Import and query an existing Vitest 3.2 JSON report to explore test failures, file-level errors and original diagnostic evidence.
find-simplifications
Use for a periodic repo-wide sweep of qwen-code for accumulated excess surface — dead components and files, orphaned locale keys, exports nothing consumes, added-then-removed scaffolding — filing candidates on a tracking issue and landing only what a maintainer has said yes to.
