evolve

evolve is a command for coding agents from sangrokjung/claude-forge. It costs 13 tokens per session (1,165 once invoked), scanned A, original, MIT.

A command that groups related learned working preferences, called instincts, into higher-level skills, slash commands, or agents. It uses the pattern of each instinct to suggest the appropriate structure.

In plain words
What is it for?
Finding clusters of related instincts and generating or suggesting skills, commands, and multi-step agents.
Why use it?
It helps turn many small observations into reusable automation instead of leaving them as disconnected rules.

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.

npx agentmods add commands/sangrokjung/claude-forge/evolve
Clone the repo
git clone --depth 1 https://github.com/sangrokjung/claude-forge

Or install claude-forge, the plugin that ships this one along with the rest of its 33 skills, 39 commands, 17 agents.

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 today.

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.

Evolve Command

Implementation

python3 ~/.claude/skills/continuous-learning-v2/scripts/instinct-cli.py evolve [--generate]

Analyzes instincts and clusters related ones into higher-level structures:

  • Commands: When instincts describe user-invoked actions
  • Skills: When instincts describe auto-triggered behaviors
  • Agents: When instincts describe complex, multi-step processes

Usage

/evolve                    # Analyze all instincts and suggest evolutions
/evolve --domain testing   # Only evolve instincts in testing domain
/evolve --dry-run          # Show what would be created without creating
/evolve --threshold 5      # Require 5+ related instincts to cluster

Evolution Rules

→ Command (User-Invoked)

When instincts describe actions a user would explicitly request:

  • Multiple instincts about "when user asks to..."
  • Instincts with triggers like "when creating a new X"
  • Instincts that follow a repeatable sequence

Example:

  • new-table-step1: "when adding a database table, create migration"
  • new-table-step2: "when adding a database table, update schema"
  • new-table-step3: "when adding a database table, regenerate types"

→ Creates: /new-table command

→ Skill (Auto-Triggered)

When instincts describe behaviors that should happen automatically:

  • Pattern-matching triggers
  • Error handling responses
  • Code style enforcement

Example:

  • prefer-functional: "when writing functions, prefer functional style"
  • use-immutable: "when modifying state, use immutable patterns"
  • avoid-classes: "when designing modules, avoid class-based design"

→ Creates: functional-patterns skill

→ Agent (Needs Depth/Isolation)

When instincts describe complex, multi-step processes that benefit from isolation:

  • Debugging workflows
  • Refactoring sequences
  • Research tasks

Example:

  • debug-step1: "when debugging, first check logs"
  • debug-step2: "when debugging, isolate the failing component"
  • debug-step3: "when debugging, create minimal reproduction"
  • debug-step4: "when debugging, verify fix with test"

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 sangrokjung/claude-forge (822 stars, last pushed yesterday), licensed MIT. It adds 13 tokens to every session and 1,165 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 2026-09-03.
