evolve

A command for pausing during a coding task to recall relevant past results, reflect on the current work, and save lessons learned.

In plain words
What is it for?
Use it to review recent task outcomes, record what worked or failed, or run a fuller evolution review when the Evolver tool is installed.
Why use it?
It helps prevent useful experience from being lost between tasks and makes failures or successes easier to learn from.

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.

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 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

/evolve

Trigger a deliberate evolution step for the current task.

  1. Recall. Look at the evolution memory the SessionStart hook injected (or read the tail of the memory graph at ~/.evolver/memory/evolution/memory_graph.jsonl, or the project's memory/evolution/memory_graph.jsonl if present). Summarize any recent outcome — success or failure — that is relevant to what we're working on.

  2. Reflect. Given the current diff / task state, state in one or two lines: what worked, what didn't, and what the durable lesson is.

  3. Record. The Stop hook records outcomes automatically at task end. If the user wants to run the full engine now, and @evomap/evolver is on PATH, run:

    evolver run
    

    to execute a full evolution cycle (or use /evolver:run). If it is not installed, tell the user the outcome will still be captured automatically by the Stop hook, and that npm install -g @evomap/evolver unlocks the full review-and-solidify cycle.

Keep this lightweight — /evolve is for an explicit checkpoint, not a ceremony on every turn.

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 command published in the GitHub repository EvoMap/evolver-claude-code-plugin (12 stars, last pushed 12d ago), licensed MIT. It adds 22 tokens to every session and 310 once invoked, about $0.0001 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 2026-08-30.
