| description | The genome's lifecycle and hygiene, all in one place. Fire on "review the skills", before adding/splitting/merging any skill, when docs/state/miss-log.md has entries, or periodically when no pass has run for a while. ALSO fire the moment a lesson lands (a root cause found, a tool swapped, a convention decided, a default overridden, a mistake repeated) - load references/evolve.md; and on "absorb/steal from <repo>" or "spawn a project from this one" - load references/absorb.md. Owns abstraction altitude, consolidation, the skill cap, authoring standards, and decay. |
skill-manager — the one skill that is aware of all the others
Individual lessons enter through the evolve procedure, one reviewed diff at a time.
Somebody still has to see the whole genome: whether the pieces are at the right
altitude, whether gaps and corpses are accumulating. That somebody is this skill, and
the periodic pass runs with FRESH context — the writer of a skill never grades it.
Nested-skill architecture (policy, decided 2026-07-11)
- Few top-level skills, lazy references inside. A skill's body is the always-loaded
front door; variants and less-common procedures live in
references/ files loaded
only when their trigger row matches. Do not rely on separate sibling skills
auto-triggering for sub-procedures.
- Hard cap: 10 top-level skills; prefer 5-7. At the cap, adding a skill requires
first consolidating two related ones (merge into core + references). Current
top-level set (4):
workflow, skill-manager, socials, bootstrap.
- Portability. Embed the external knowledge the genome needs (e.g. authoring
standards in
references/authoring.md) so any coding agent operating this repo has
it — never depend on a specific tool's plugin being installed.
The structural rules (load-bearing, not style)
- Skills exist per task-shape, never per incident. A recurring bug becomes one
appended procedure in an existing skill, not a new skill.
- Variants of one shape are
references/ inside one skill (bootstrap +
references/python.md; workflow + references/scale.md), never sibling skills.
- Altitude smells: the same diff recurs after a fix → it was patched too low; one
edit forces rewriting siblings → it lives too high.
- Bodies stay under ~500 lines (alarm at 150). A bloated skill fails silently — it
stops being read carefully. Push volatile detail down into references; push behavioral
rules up into CLAUDE.md only when truly session-wide.
- No version numbers in skill bodies. Decision procedures survive years; pins go
stale invisibly. Dated observations are allowed in references, marked with their date.
- Authoring standards (descriptions as triggers, progressive disclosure, eval method):
references/authoring.md.
The lifecycle procedures (lazy parts)
The miss-log
docs/state/miss-log.md, one line per event: a task arrived that matched no skill, and
the agent free-styled it. Logging the miss is how the system notices a hole in itself —
an unlogged miss is the system silently deciding it is complete. Any skill (or none)
being active, when you catch yourself working without a matching skill: log one line,
keep working.
The periodic pass (run it fresh; output = proposed diffs, human approves)
- Firing audit — has each skill fired in the last N sessions? Never fires: is the
description too shy (fix the description) or the skill dead (archive it)?
- Rot scan — any line encoding a version number or a stale claim? Hand those to
workflow/references/rot-check.md.
- Altitude audit — is one skill doing two stages' work (split), or two skills doing
one stage's (merge)? Apply the smells above, and the cap.
- Miss-log triage — entries that recur have earned a procedure; where does it live
(existing skill vs new)? Entries that never recurred get pruned.
- Threshold review — N sessions, line limits, staleness windows: the manager sets
its own thresholds and adjusts them, through the same reviewed-diff door as
everything else. Current thresholds live at the bottom of this file.
Current thresholds (self-set, reviewed like everything else)
- Firing audit window: 10 sessions.
- Body size alarm: 150 lines (hard ceiling 500).
- A raw claim older than 6 months is stale until re-verified.
- A miss-log entry that recurs twice has earned a home.
- Top-level skill cap: 10 hard, 5-7 preferred (2026-07-11).
