The bin skills were the only plugin without per-skill READMEs, so a reader
had to open SKILL.md — an agent-facing contract, not an explainer — to learn
what a skill does and when it fires. Each README states purpose, triggers and
boundaries for a human audience, leaving SKILL.md free to stay terse.
diagnose read its feedback-loops reference unconditionally, so every
invocation paid for guidance most runs never used; the read is conditional
again and the per-invocation cost drops from 1,278 to 831 words. Its HITL
template moves to assets/ because it is copied out, not read as reference.
prototype's two branch flows move into references/ for the same reason —
only one branch is ever taken.
research could not search the codebase it was asked to research without Grep
and Glob. caveman's description had grown into a paragraph where one sentence
carries the trigger. Four references pointed at things that do not exist: a
to-prd skill, a /setup-matt-pocock-skills command, two cross-skill ../ links
that only resolve in the source tree, and two places calling this project's
Gitea host GitHub.
Addresses #114.
Sets `disable-model-invocation: true`, so the host withholds caveman from
the model-visible skill listing. It stops paying preload tax and can only
be reached by typing /caveman.
The reason is not the 287 characters. caveman's description was almost
entirely a trigger list -- "caveman mode", "talk like caveman", "less
tokens", "be brief" -- and "be brief" is a false-positive magnet: a user
asking for brevity wants short answers, not dropped articles and
`Respond terse like smart caveman`. Removing the skill from the router
deletes the bad trigger. User's call, made explicitly.
Safe to flag because the flag also hard-blocks the Skill tool, so any
inbound route from another skill would break. Re-checked all 39
descriptions and bodies after four waves of retrofit rewrites: every
mention of caveman is documentation, research notes or the lockfile.
Nothing routes to it.
The description is rewritten as human-facing text, since it is no longer
a routing surface -- it now says how to turn the mode on and off rather
than listing phrases for a reader that can no longer see it.
The two remaining SUGGESTIONs are #108: the boundary-clause check fires on
hand-invoked skills, which ADR-0020 contractually exempts. Advisory, and
not to be "fixed" in the skill.
Preload tax 10,002 -> 9,732 chars across 37 model-visible skills.
