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.

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 | $0.00018 | $0.00249 |
| Opus 5 | $0.00009 | $0.00125 |
| Sonnet 5 | $0.00004 | $0.00050 |
| Haiku 4.5 | $0.00002 | $0.00025 |
Grade A, and why
readme-skill 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 5d 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
readme-skill
The smallest grouped skill: a description but deliberately no version
and no license.
What this fixture covers:
- A grouped skill with a partly-filled manifest, so the desktop Skills tree has a row with an empty version column under a group.
- Update detection with nothing to fall back on. Because
versionis absent, the install manifest records no version, and staleness is decided purely by comparing the skill's content hash against the one recorded at install. Edit this file, then check the skill reports an available update - and check that editing it back clears the update, since the hash returns to its original value. - The second skill of the
docs-writinggroup, which keeps the group alive for MCP group discovery even ifchangelog-skillis removed.
The content hash covers this file only, and .skid.yml is always excluded from
it by basename - so the hash a skill records is the same before and after that
file is written.
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.

readme-skill is a skill published in the GitHub repository lorem-dev/skillkeeper-test-repo (2 stars, last pushed 11d ago), licensed MIT. It adds 18 tokens to every session and 249 once invoked, about $0.0001 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.
