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 | $0.00036 | $0.00710 |
| Opus 5 | $0.00018 | $0.00355 |
| Sonnet 5 | $0.00007 | $0.00142 |
| Haiku 4.5 | $0.00004 | $0.00071 |
Grade A, and why
evolve 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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/guild:evolve — self-maintenance (Guild-on-Guild)
Kicks off skill evolution. Maps to skill guild:evolve-skill.
Canonical grammar
/guild:evolve <id> [--auto]
<id>(positional, required) — the skill or evolvable instance to evolve. This is the same single positional the legacy[skill]form named; it is widened, not duplicated —<id>covers a base skill name and an instance id.--auto— run the promotion pipeline unattended; the promotion gate is still respected (gate criteria must pass, no regression), unchanged.
Gates
Promotion gate I (manual) / A (--auto, gate-respected). Never
auto-edits a skill without passing the promotion gate; rejected attempts are
archived, not deleted.
Output
.guild/evolve/<run-id>/**, version bump on promote.
Run-start preflight (settings-control-and-tmux U3/U6)
Before the evolve-skill pipeline runs — and before run-trace start — the run-trace CLI runs this preflight for you — you do not
call runStartPreflight yourself.
Since wave 2, run-trace.js start (below) is the sole caller of
runStartPreflight (scripts/lib/runstart-preflight.ts; canonical contract in
guild.md §Run-start preflight): on start the CLI resolves the 7-source
inheritance chain, validates closed keys, probes tmux, detects providers, and
writes .guild/runs/<id>/resolved-settings.json (+ a compact settings_ref in
run.yaml) automatically before the run opens. If this command needs the
resolved config — e.g. the dispatch backend effective.agent_mode — read the
snapshot back with readResolvedSettingsSnapshot(runId, { cwd }); never
re-resolve.
Run recording
Before the evolve-skill is invoked, start a run (SC-B, §435):
node ${GUILD_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT:-$HOME/.local/share/guild/dist/claude-code}}/hooks/dist/run-trace.js start \
--command=/guild:evolve \
--cwd "$(pwd)"
run-class default (full). Records the run before the promotion gate so
the complete session — shadow evaluation and promotion decision — is
replayable from the entrypoint. Writes to
.guild/evolve/ — not .guild/initiatives/ (NN#5 unaffected). No
--initiative flag.
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.

evolve is a command published in the GitHub repository lookatitude/guild (7 stars, last pushed yesterday), licensed MIT. It adds 36 tokens to every session and 710 once invoked, about $0.0002 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.
