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 | $0.00012 | $0.00334 |
| Opus 5 | $0.00006 | $0.00167 |
| Sonnet 5 | $0.00002 | $0.00067 |
| Haiku 4.5 | $0.00001 | $0.00033 |
Grade A, and why
chain-a 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 it actually says
chain-a
The head of the only multi-hop chain in this repository. Installing it must
pull in requires/chain-b and requires/chain-c.
What this fixture covers:
- The strict, namespaced
skillkeeper.requiresfield, which is the spelling every new skill should use. - Transitivity. One hop would be satisfied by a resolver that only looked
at direct references; two hops are not.
chain-a -> chain-b -> chain-cis the shortest chain that proves the install order is a closure rather than a single lookup. - A reference naming a skill's resolved identity (
requires/chain-b), not its directory path. The two happen to coincide here because this repository has noskillkeeper.repo.yaml; anameorgroupoverride would move the identity and the reference would have to follow it.
Expected behaviour
skillkeeper skill install requires/chain-a --agent claude installs three
skills and prints one line per dependency:
Skill installed: requires/chain-a -> ...
Skill installed as a dependency: requires/chain-b -> ...
Skill installed as a dependency: requires/chain-c -> ...
repo lint reports nothing for any member of the chain. It is the positive
control the negative fixtures in this group are read against.
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.

chain-a is a skill published in the GitHub repository lorem-dev/skillkeeper-test-repo (2 stars, last pushed 11d ago), licensed MIT. It adds 12 tokens to every session and 334 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.
