Getting it into your agent

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 | $0.00048 | $0.01300 |
| Opus 5.5 | $0.00019 | $0.00520 |
| Sonnet 5.5 | $0.00010 | $0.00260 |
| Haiku 4.5 | $0.00005 | $0.00130 |
Grade A, and why
skill-git:delete scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 145 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are running /skill-git:delete. Follow these steps exactly.
Tool Loading
Before doing any work, load all required tools in a single ToolSearch call:
select:TaskCreate,TaskUpdate,TaskList,AskUserQuestion
Do not issue multiple ToolSearch calls.
Task Tracking
You MUST create a task for each item below and update each task's status as you progress (pending → in_progress → completed):
- Select skill — parse arguments or present interactive list
- Confirm deletion — show warning and wait for explicit user confirmation
- Execute deletion — call sg-delete.sh --execute
- Report result — display outcome to user
Prelude
!bash "${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 (e.g. a typo or implicit default).
- If STATUS is
not_initializedand INITIALIZED_AGENTS is non-empty, suggest/skill-git:init -a <agent>. - If STATUS is
not_initializedand INITIALIZED_AGENTS is empty, tell the user to run/skill-git:initfirst. - If STATUS is
error, display REASON as a plain-language error and stop.
Use AGENT, GLOBAL_BASE, and SKILLS_JSON from prelude output for all subsequent steps.
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>.
Step 1 — Select Skill
If a skill name is provided in $ARGUMENTS:
Run:
bash "${CLAUDE_PLUGIN_ROOT}/scripts/sg-delete.sh" --info "<skill_name>" "<global_base>" '<skills_json>'
If STATUS=not_found, tell the user:
Skill "<skill_name>" is not registered.
Run /skill-git:list to see all registered skills.
Then stop.
Use the returned SKILL_PATH, SKILL_VERSION, IS_SYMLINK, IS_DIRTY, DIRTY_SUMMARY for the next step.
If no skill name is provided:
Run:
bash "${CLAUDE_PLUGIN_ROOT}/scripts/sg-delete.sh" --list "<global_base>" '<skills_json>'
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:delete is a command published in the GitHub repository KnowledgeXLab/skill-git (42 stars, last pushed 6mo ago), licensed MIT. It adds 48 tokens to every session and 1,300 once invoked, about $0.0002 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.
