evolve

A skill for turning Skill Autopilot’s recorded usage patterns into a small set of personalized working rules.

In plain words
What is it for?
Use it when Autopilot announces an evolution window or when you want to review usage events and update learned preferences.
Why use it?
It helps the autopilot adapt to repeated habits while requiring consistent evidence before changing its guidance.

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 3d 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

Evolution pass (prompt-space gradient descent)

You are updating this system's weights: the personalized rules injected into every prompt. Be conservative — a wrong learned rule costs the user on every message.

Procedure

  1. Read ~/.claude/command-autopilot/events.jsonl. Also read learned.json if present (schema below).
  2. Cluster events by task-type × command/skill. Look for consistent patterns, for example:
    • a command suggested repeatedly and consistently dismissed → candidate negative rule
    • a skill invoked on the same kind of task again and again → candidate positive rule ("invoke X early for Y-type tasks")
    • a habit self-used regularly → mastered, teaching for it should stop
  3. Apply the discipline:
    • Promote only patterns with ≥3 consistent observations and no contradicting evidence → status: "in_force".
    • Demote existing in_force rules contradicted by new evidence (decrement evidence; at 0, set status: "candidate").
    • Decay: rules not reconfirmed for ~60 days → delete.
    • Max 5 in_force rules; each text ≤ 25 tokens, English, imperative, generic phrasing ("research-type tasks: offer /fork early").
    • NEVER write rules that override the safety net (/rewind) or the one-suggestion contract.
  4. Write learned.json:
{
  "updated": "<ISO>",
  "rules": [
    {"text": "...", "evidence": 4, "first": "<ISO>", "last": "<ISO>", "status": "in_force"}
  ]
}
  1. Archive processed events — rotate FIRST to avoid racing concurrent appends: rename events.jsonl to events-archive-<timestamp>.jsonl, and only then read the renamed file for the distillation. New events land in a fresh events.jsonl untouched. (If you already read before rotating, rotate anyway and accept the tiny overlap.)
  2. Report to the user in their language: what was learned (each rule + its evidence), what was demoted or deleted, and one line on what will change. If nothing met the bar, say so plainly — no fabricated learnings.
Changes

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 WinterDDo/claude-code-skill-autopilot (6 stars, last pushed 2mo ago), licensed MIT. It adds 59 tokens to every session and 540 once invoked, about $0.0003 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.
