Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00066 | $0.01374 |
| Opus 5.5 | $0.00026 | $0.00550 |
| Sonnet 5.5 | $0.00013 | $0.00275 |
| Haiku 4.5 | $0.00007 | $0.00137 |
Grade A, and why
skill-git:init 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 2mo 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.

Task Tracking
You MUST create a task for each item below and update each task's status as you progress (pending → in_progress → completed):
- Resolve agent — detect or prompt for the target agent (claude, gemini, codex, openclaw)
- Explain what will happen — summarize the init steps to the user before executing
- Verify git is installed — check
git --version - Run initialization — execute
sg-init.shand display the full output
Step 1 — Resolve agent
Parse $ARGUMENTS for a -a <value> flag.
If -a was provided: use that value as agent. Validate it against the known agents:
| value | base_dir |
|---|---|
claude |
~/.claude |
gemini |
~/.gemini |
codex |
~/.codex |
openclaw |
~/.openclaw/skills, ~/.openclaw/workspace/skills/ |
If the value is not in the table, respond:
Unknown agent: "<value>"
Supported agents: claude, gemini, codex, openclaw
Then stop.
If -a was not provided: auto-detect using the following steps in order:
Step A — Check parent process:
Run ps -p $PPID -o comm= and match the output:
- contains
claude→claude - contains
gemini→gemini - contains
codex→codex - contains
openclaworclaw→openclaw
If matched, set agent and note: (agent auto-detected from process: <agent>)
Step B — Check user config (if Step A fails):
Read ~/.skill-git/config.local.md and look for a default_agent field:
---
default_agent: gemini
---
If found, set agent from that value. Note: (agent from config: <agent>)
Step C — Prompt user (if Step B also fails):
Tell the user that the CLI tool could not be detected automatically, then use the AskUserQuestion tool:
- question: "Which agent are you initializing skills for?"
- header: "Agent"
- options:
- label: "claude", description: "~/.claude/skills/"
- label: "gemini", description: "~/.gemini/skills/"
- label: "codex", description: "~/.codex/skills/"
- label: "openclaw", description: "~/.openclaw/skills/ + ~/.openclaw/workspace/skills/"
- multiSelect: false
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.

skill-git:init is a command published in the GitHub repository KnowledgeXLab/skill-git (42 stars, last pushed 6mo ago), licensed MIT. It adds 66 tokens to every session and 1,374 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-08-30.
