What it does

Evolve is an agent skill from softspark/ai-toolkit. Analyzes agent/skill failures, drafts prompt/permission fixes. Triggers: improve agent, refine skill, system prompt, optimize agent.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in AI & LLM Engineering, covering Prompt engineering. The repository describes itself as: Professional-grade AI coding toolkit: 94 skills, 44 agents, multi-platform (Claude, Cursor, Windsurf, Copilot, Gemini, Cline, Roo Code, Aider, Augment, Antigravity, Codex CLI… The licence is Apache-2.0.

Requirements

Pre-approved tools (allowed-tools): Read, Edit, Grep, Glob

Workflow steps

4 steps, taken from the step headings in SKILL.md.

Analyze

Report

What it can do on your machine

Read from SKILL.md and the folder at commit d64db2b. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
- Read
- Edit
- Grep
- Glob
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Evolve loads about 1k tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 439 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~35
When it runs · the whole SKILL.md, loaded when a task matches: ~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Evolve Command

$ARGUMENTS

Triggers the Meta-Architect to improve agent and skill definitions based on observed patterns.

Usage

bash

/evolve [source]
# /evolve learnings        : analyze kb/learnings/ for recurring failure patterns
# /evolve last-failure     : analyze the most recent error log
# /evolve agents           : audit all agent definitions for gaps

Protocol

1. Analyze

Read the input source and extract actionable patterns:

learnings: grep kb/learnings/ for entries tagged failure, retry, timeout, or inefficiency
last-failure: read the most recent file in kb/learnings/ and identify root cause
agents: scan all .md files in app/agents/ for missing tools, vague prompts, or mismatched model tiers

2. Design

Draft changes targeting the identified patterns:

Target	File Location	Change Type
Agent definitions	`app/agents/*.md`	Frontmatter (tools, model), system prompt text
Skill definitions	`app/skills/*/SKILL.md`	Description, workflow steps, allowed-tools
Rules	`app/rules/`	New or updated rule files

Show the proposed diff to the user before applying.

3. Implement

Apply approved changes. After each edit:

Run python3 scripts/validate.py to confirm structural integrity
Verify YAML frontmatter parses without errors
Confirm no forbidden patterns (eval, exec, shell=True)

4. Report

Create a summary documenting what evolved:

markdown

## Evolution Report
- **Source**: [learnings | last-failure | agents]
- **Pattern found**: [description of failure/inefficiency]
- **Changes applied**:
  - `app/agents/[name].md`: [what changed and why]
- **Validation**: passed / failed

Rules

MUST delegate file edits to the meta-architect agent — this command is the trigger, the agent owns the changes
MUST have a concrete failure signal (recurring error, named incident, repeated correction) before evolving — do not mutate based on vibes
NEVER evolve an agent based on a single failure instance — evolution is pattern-matching, not reaction
NEVER touch .claude/agents/* files directly from this skill; meta-architect is the only agent with that authority
CRITICAL: every evolution names the trigger, the change, and the expected measurable shift (e.g., "reduces false routing of /debug to /fix")
MANDATORY: run scripts/validate.py --strict after every applied change; roll back if the score drops

Show full SKILL.md (186 more words)Show less

Gotchas

Small changes to an agent's description can silently re-route a dozen adjacent queries. After an evolution, run the skill router against a saved set of representative queries to confirm no drift.
kb/learnings/ entries without a status: final frontmatter field are often drafts — aggregating them treats speculative observations as validated patterns. Filter by status before mining.
"Last-failure" often points at the symptom, not the root cause. A route-to-wrong-agent failure may actually be a description-field ambiguity; fix the description, not the router.
Changes to agent frontmatter fields (tools, model) propagate to the installed global config only after ai-toolkit update. A locally-evolved agent still runs old behavior until the user reinstalls.
Evolution in isolation invites regression. Keep a changelog (kb/learnings/ entries or CHANGELOG.md) so future sessions can see what was tried and reverted.

When NOT to Use

For a specific, known agent edit — call meta-architect directly
For fixing a failing test — use /fix or /debug
For auditing current skill/agent quality — use scripts/evaluate_skills.py and scripts/audit_skills.py --ci
For creating a new agent — use /agent-creator
When no recurring pattern exists (single data point) — wait and observe; do not over-fit to noise

Questions about Evolve

What does Evolve do?

Analyzes agent/skill failures, drafts prompt/permission fixes. Evolve is an agent skill from softspark/ai-toolkit. Analyzes agent/skill failures, drafts prompt/permission fixes.

When should I use Evolve?

Evolve fits situations like: tasks that involve Prompt engineering.

How do I install Evolve in Claude Code?

Run `npx skills add softspark/ai-toolkit --skill evolve -a claude-code`. Or copy the skill folder (app/skills/evolve in softspark/ai-toolkit) into .claude/skills/evolve in your project. Claude Code loads it when a task matches its description.

How do I install Evolve in Codex?

Run `npx skills add softspark/ai-toolkit --skill evolve -a codex`. Or copy the skill folder (app/skills/evolve in softspark/ai-toolkit) into .agents/skills/evolve in your project. Codex loads it when a task matches its description.

Can I use Evolve in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add softspark/ai-toolkit --skill evolve -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/evolve, .gemini/skills/evolve, .github/skills/evolve and .opencode/skills/evolve in your project.

What does Evolve need to run?

Going by SKILL.md and its folder, Evolve needs the command-line tools its instructions call (python3). Our summary lists: Python 3. Its frontmatter pre-approves these tools: Read, Edit, Grep, Glob.

Does Evolve access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Evolve safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Evolve use?

Evolve is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Evolve use?

About 1k tokens (SKILL.md is roughly 4.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Evolve?

Skills that share tags, products or a category with Evolve: Prompt Improver (severity1/claude-code-prompt-improver, 1.9k stars), Prompt Engineering Patterns (ynulihao/AgentSkillOS, 617 stars), Patch Creation (Piebald-AI/tweakcc, 2.5k stars) and LLM Application Dev (MoizIbnYousaf/ai-agent-skills, 1.1k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Evolve?

softspark (a GitHub user) maintains it in softspark/ai-toolkit, which has 179 GitHub stars. The repository holds 112 skills in this directory. The repository was last updated on October 7, 2026.
