agent-evolve

A tool for reviewing how an AI agent changes over time and managing proposed improvements to its saved versions.

In plain words
What is it for?
Use it to inspect evaluation trends, create proposals, accept or reject changes, view version history, and roll back an agent to an earlier version.
Why use it?
It helps identify quality decline or repeated weaknesses and keeps accepted changes backed by saved versions that can be restored.

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

agent-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.

Agent Evolve

Wraps cc:cc-agents skill.

Analyze agent quality over time, draft heuristic proposals for declining/flat-low dimensions, apply proposals through the double-loop gate, and rollback to prior versions via saved snapshots. Delegates to cc:cc-agents skill.

When to Use

  • Analyze trends, data sources, and patterns without writing a proposal (--analyze)
  • Generate proposals after evaluation drift or repeated review feedback (--propose-only)
  • Apply proposals through the deterministic double-loop gate with backup and rollback (--accept, --rollback)
  • Track applied versions over time (--history)

Arguments

Argument Description Default
<name> Name of the agent (required)
--analyze Print trend table, score/grade, data-source inventory, and pattern summary false
--from <date> Analyze evaluations since date (ISO 8601) latest
--propose-only Draft proposals without applying false
--accept <id> Apply a saved proposal by ID -
--reject <id> Reject a saved proposal by ID -
--history List applied proposal versions from the store false
--rollback <id> Restore a prior version by proposal_id (requires --confirm) -
--confirm Confirm a destructive operation (required for --rollback) false
--ingest <file> Agent-authored proposal JSON (ingest-in mode) -
--json Output machine-readable JSON (envelope-out with --propose-only) false
--margin <n> Δ-margin gate threshold for accept (default 0.05) 0.05
--eval-gate Enable the empirical behavior gate when eval cases exist false
--target Target platform claude

Examples

# Generate persisted proposals
/cc:agent-evolve ./agents/my-agent.md --propose-only
# Analyze trends without writing a proposal
/cc:agent-evolve ./agents/my-agent.md --analyze
# Apply a proposal
/cc:agent-evolve ./agents/my-agent.md --accept agent-evolve-2026-06-21-001
# List applied versions
/cc:agent-evolve ./agents/my-agent.md --history
# Rollback to a prior version
/cc:agent-evolve ./agents/my-agent.md --rollback agent-evolve-2026-06-21-001 --confirm

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.

agent-evolve is a command published in the GitHub repository gobing-ai/superskill (5 stars, last pushed 6d ago), licensed Apache-2.0. It adds 13 tokens to every session and 891 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 2026-08-31.
