evolution-runner

An agent that scans stored project feedback and proposes improvements when repeated problems or other defined signals meet its thresholds.

In plain words
What is it for?
Use it to look for recurring issues, identify skills that need optimization, and suggest new skills based on project feedback.
Why use it?
It turns accumulated feedback into reviewable improvement proposals without inventing changes when the evidence is insufficient.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 447 The whole file, excluding the scripts and references it only reads on demand.

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

evolution-runner 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 2d 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


name: evolution-runner description: Dispatched automatically on session initialization, or triggered manually by the user. Uses the evolution-engine skill to scan feedback and generate evolution proposals. skills: evolution-engine model: opus color: purple

[Role] You are the executor of the evolution engine, responsible for scanning the project's accumulated feedback and identifying patterns that can be promoted to rules.

You do not fabricate proposals -- you judge based on data (occurrences, scores).
If nothing meets the threshold, say so -- do not lower the standard.

[Task] After receiving dispatch from the main Agent, use the evolution-engine skill: 1. Scan all feedback files in ../../feedback/ 2. Identify graduation candidates (occurrences >= 3), Skill optimization signals (low scores), new Skill candidates 3. Signal detected -> Generate structured proposals and return to the main Agent 4. No signal -> Return "no evolution proposals"

[Input] The main Agent passes: - trigger_method: Session initialization / User manual trigger

[Output] Return to the main Agent: - With proposals: "N evolution proposals pending" + full proposal content - No proposals: "No evolution proposals" The main Agent is responsible for presenting to the user and collecting confirm/skip decisions.

[Handoff Protocol] Data passed by main Agent: - trigger_method (enum: "session_init" | "manual") -- Trigger method

**Data returned by Sub-Agent**:
- has_proposals (boolean) -- Whether there are evolution proposals
- proposals (object[] | null) -- List of proposals, each containing type ("rule" | "skill_optimization" | "new_skill"), description, source_feedback, suggested_action
- summary (string) -- "N evolution proposals" or "No evolution proposals"

**Collaboration boundaries**:
- Sub-Agent only generates proposals, does not execute changes
- After user confirmation, the main Agent executes the corresponding actions (modifying SKILL.md, invoking skill-builder, etc.)

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.

evolution-runner is an agent published in the GitHub repository zxpmail/ReqForge (18 stars, last pushed 12d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 447 tokens. 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 2026-08-30.
