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 | $0.00017 | $0.00415 |
| Opus 5 | $0.00009 | $0.00208 |
| Sonnet 5 | $0.00003 | $0.00083 |
| Haiku 4.5 | $0.00002 | $0.00042 |
Grade A, and why
script-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 2d 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
script-skill
What this fixture covers:
- The
executablesmanifest field. Paths are skill-relative, not repository-relative:bin/run.sh, neverscript-skill/bin/run.sh. - Selective
+x. After install,bin/run.shandbin/check.pymust be executable, andlib/shared.shmust not be - it is deliberately left out of the list. That contrast is the whole point of shipping a third script. +xbeing applied, not inherited. All three scripts are committed with mode644, so the executable bit on the two declared paths can only come from install acting on theexecutableslist. Keep them644in the repository: a755source mode would make this fixture unable to tell the two mechanisms apart.- Two files in one subdirectory plus one file in another, so the uninstall path has more than one empty directory to prune.
RULES.mdas the fallback. This skill shipsRULES.mdand noGUIDE.md, soRULES.mdis what reaches the agent's guidance file. Compare withdocumented-skill, whereGUIDE.mdwins because both exist.
Note that the configured executable globs are a separate mechanism: a path can
also become executable by matching a glob from SkillKeeper's own configuration,
without being named here. lib/shared.sh stays non-executable only as long as
no configured glob matches it.
The scripts do nothing but print a line. Running a skill is the agent's job; SkillKeeper only installs files and edits config regions.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

script-skill is a skill published in the GitHub repository lorem-dev/skillkeeper-test-repo (2 stars, last pushed 8d ago), licensed MIT. It adds 17 tokens to every session and 415 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.
