evolve

evolve is a skill for Claude Code, Codex from alexmond/alexmskills. It costs 119 tokens per session (1,894 once invoked), scanned A, original, MIT.

A role-maintenance checker for persona files stored in `.claude/roles/`.

In plain words
What is it for?
Use it to audit role files and propose consolidations, updates, or moving lessons from an individual role into the shared team rules. Proposed changes require user approval.
Why use it?
It finds repeated lessons, outdated references, and growing differences between a role's instructions and how it is actually used.

Skill for Claude CodeCodex

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Token cost

What it costs to keep this loaded

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.

Security

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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Evolve Roles

Try it: /roles:evolve — or say "audit the roles and propose refinements".

Graduation gets a learning into the role file. Evolution is the loop that keeps it useful afterwards: learnings consolidate as the same lesson recurs in new forms; entries go stale when the artifact they cite is renamed or removed; the Charter and Body drift out of date when the cumulative learnings have effectively re-shaped how the role behaves. Without this loop a role file calcifies — every new run appends, nothing refines, and after enough sessions the file is a layered archaeology no future reader will trust.

This skill runs that loop. Never silently rewrites a role file. Every proposal is shown to the user with the evidence; the user accepts, edits, or rejects each one.

Proactive runs and non-goals

Beyond the say-it phrases (in the description), run this when the SessionStart roles-init-audit.py hook surfaces high solo-learning counts (>15 per role) or cross-orchestrator usage signals — those are reactive nudges; this is the deeper pass that acts on them.

Not for one-off "add this learning to the role" edits: the orchestrator that produced the lesson appends directly, and a single new entry needs no audit.

The four audit dimensions

For each role file in .claude/roles/ (skipping consumer registries crew.md / panel.md / research.md / registry.md), run all four:

1. Consolidation candidates

When the same topic appears in ≥3 Learnings (core) entries — same artifact, same failure mode, same recurring critique — propose a single merged rule that captures the load-bearing pattern, and a proposed strike-through of the three originals.

Detection signal: clustering of backticked artifacts (same ClassName.method or path/to/file cited across multiple entries), or repeated lead phrases ("always", "never", "remember that").

Threshold: 3+ entries on one topic. Below that, individual entries still carry distinct nuance worth keeping.

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 skill published in the GitHub repository alexmond/alexmskills (6 stars, last pushed today), licensed MIT. It adds 119 tokens to every session and 1,894 once invoked, about $0.0006 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.
