skill-git:merge

A command that combines two or more similar skills into one skill with their rules and supporting files brought together.

In plain words
What is it for?
Use it after finding duplicate or related skills, when you want one consolidated skill and a single name and location for it.
Why use it?
It reduces overlap between skills while requiring you to review conflicts and approve destructive changes.

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 C, and why

skill-git:merge scanned grade C with 1 finding 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

How it starts

The opening of the file, as written. The whole thing — 537 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are running /skill-git:merge. Follow these steps exactly.

Merge never overwrites anything silently. Every destructive action requires explicit user confirmation before execution.

Task Tracking

You MUST create a task for each item below and update each task's status as you progress (pending → in_progress → completed):

  1. Resolve skills to merge — parse arguments or select from latest scan results
  2. Load topics and show overlap — extract/cache rules, cluster into topics, display summary
  3. Resolve conflicts — present each conflicting topic and record user decisions (skip if none)
  4. Choose name and base folder — prompt for merged skill name and which folder to use as base
  5. Synthesize merged SKILL.md — generate draft, show for approval, iterate on edits
  6. Write files — write SKILL.md, copy non-SKILL.md files, update config.json, delete sources
  7. Commit merged skill — pre-flight check, confirm, run git add/commit/tag

Prelude

!bash "${CLAUDE_PLUGIN_ROOT}/scripts/sg-prelude.sh" $ARGUMENTS

If STATUS is not ok:

  • Re-examine RAW_ARGUMENTS — check if the user expressed an agent name or intent that can be semantically resolved.
  • If you can determine intent, note the resolution and proceed.
  • If STATUS is not_initialized and INITIALIZED_AGENTS is non-empty, suggest /skill-git:init -a <agent>.
  • If STATUS is error, display REASON as a plain-language error and stop.
  • If intent cannot be resolved, display a clear error and stop.

Use AGENT, GLOBAL_BASE, and SKILLS_JSON from prelude output for all subsequent steps. The skills map referred to throughout this document is the parsed content of SKILLS_JSON.

Agent name in positional position: If $ARGUMENTS contains a known agent name (claude, gemini, codex, openclaw) as a standalone positional token not preceded by -a, silently treat it as -a <agent>: override AGENT, re-read GLOBAL_BASE and SKILLS_JSON from ~/.skill-git/config.json for that agent. Do not pass it to requested_skills.

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.
