magent-evolve

magent-evolve is a command for coding agents from gobing-ai/superskill. It costs 13 tokens per session (1,071 once invoked), scanned A, original, Apache-2.0.

A command for tracking and improving a coding agent’s configuration over time. It can analyze quality changes, draft or apply proposals, list saved versions, and restore an earlier version.

In plain words
What is it for?
Use it to review evaluation trends, create improvement proposals, apply low-risk fixes, inspect configuration history, or roll back a change.
Why use it?
It helps when an agent’s results drift or repeated review comments show that its instructions need updating. Backups and version snapshots make applied changes reversible.

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

magent-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 yesterday.

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 — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Magent Evolve

Wraps cc:cc-magents skill.

Analyze main agent config quality over time, persist refine-backed proposals, apply deterministic proposals, and inspect or rollback applied versions. Magents are frontmatter-OPTIONAL plain markdown (AGENTS.md/CLAUDE.md/GEMINI.md), so proposals on a frontmatter-less config target the body rather than a frontmatter.description field. Delegates to cc:cc-magents skill.

When to Use

  • Print a longitudinal analysis (trend table, score, data sources) without writing a proposal
  • Generate proposals after evaluation drift or repeated review feedback
  • Apply low-risk fixes through deterministic refine flow with backup and version snapshot
  • List applied versions or rollback to a prior version snapshot

Arguments

Argument Description Default
<name> Name or path of the config (required)
--analyze Print analysis summary (trends, score, data sources) without writing a proposal 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 (e.g. magent-evolve-2026-06-22-001) -
--reject <id> Reject a saved proposal -
--history List applied proposal versions from the store false
--rollback <id> Rollback to a prior version by proposal_id (requires --confirm) -
--confirm Confirm a destructive operation (required for --rollback) false
--json Output machine-readable JSON (envelope-out with --propose-only) false
--ingest <file> Consume agent-authored proposal JSON (ingest-in mode) -
--margin <n> Δ-margin gate threshold for accept 0.05
--eval-gate Enable the empirical behavior gate when eval cases exist false
--target Target platform claude

Examples

# Print longitudinal analysis (no proposal written)
/cc:magent-evolve AGENTS.md --analyze
# Generate persisted proposals
/cc:magent-evolve AGENTS.md --propose-only
# Apply a proposal
/cc:magent-evolve AGENTS.md --accept magent-evolve-2026-06-22-001
# List applied versions
/cc:magent-evolve AGENTS.md --history
# Rollback to a prior version
/cc:magent-evolve AGENTS.md --rollback magent-evolve-2026-06-22-001 --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.

magent-evolve is a command published in the GitHub repository gobing-ai/superskill (5 stars, last pushed yesterday), licensed Apache-2.0. It adds 13 tokens to every session and 1,071 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.
