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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00602 | $0.00602 |
| Opus 5 | $0.00301 | $0.00301 |
| Sonnet 5 | $0.00120 | $0.00120 |
| Haiku 4.5 | $0.00060 | $0.00060 |
Grade A, and why
aquiles-skill 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 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.
How it starts
The opening of the file, as written. The whole thing — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Aquiles Skill repository guidance
This repository packages a reusable agent skill. Keep this file small, durable, and repository-specific; put detailed workflow knowledge inside skills/aquiles/references/ and enforce repeatable checks in scripts/CI.
Source routing
| Concern | Source of truth |
|---|---|
| Skill activation and lifecycle | skills/aquiles/SKILL.md |
| Phase / specialist detail | skills/aquiles/references/*.md |
| 2026 artifact requirements and sources | skills/aquiles/references/artifact-standards.md |
| Generated product files | skills/aquiles/assets/ |
| Deterministic behavior | skills/aquiles/scripts/ and scripts/validate.py |
| Installation | install.sh |
| Public repository contract | root README/community files and .github/ |
Editing rules
- Preserve progressive disclosure: keep
SKILL.mdfocused and link optional detail directly. - Keep only
nameanddescriptioninSKILL.mdfrontmatter. - Write imperative workflow steps with explicit inputs, outputs, owner, evidence, and gate.
- Put reusable generated content in
assets/; put repeated deterministic operations inscripts/. - Treat template headings, stable IDs, CLI flags, safe defaults, and overwrite behavior as compatibility surfaces.
- Update
artifact-standards.mdwhen a material artifact contract changes; cite primary, maintained sources and record review date. - Do not make generated products inherit this repository's MIT license; licensing remains explicit opt-in.
- Keep technical access distinct from mutation authorization for Git, GitHub, Vercel, domains, environment variables, billing, and destructive actions.
- Never add live secrets,
.envvalues, cookies, customer data, or private repository contents.
Required verification
Run before commit:
python3 scripts/validate.py
Also perform the change-specific check:
- installer change: fresh isolated install from a clean clone;
- template or bootstrap change: generate a disposable product and inspect every artifact;
- workflow or safety change: forward-test representative prompts without remote mutation;
- release-gate change: test allow, deny, missing-access, and mismatched-target cases;
- documentation link change: verify links where network access is available.
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.

aquiles-skill AGENTS.md is an instructions file published in the GitHub repository luizvb/aquiles-skill (2 stars, last pushed 1mo ago), licensed MIT. It adds 602 tokens to every session, about $0.0030 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.
