Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents); mentions Codex; $skill-name invocation.

This is butgo/butgo-specdrive-lab's own configuration. It tells Claude Code and Codex how to work on butgo-specdrive-lab itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything butgo-specdrive-lab configures →

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.

ModelPer sessionOnce invoked
Fable 5.1 $0.00042 $0.00263
Opus 5.5 $0.00017 $0.00105
Sonnet 5.5 $0.00008 $0.00053
Haiku 4.5 $0.00004 $0.00026

Security

Grade A, and why

specdrive-skills 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.

What it actually says

Specdrive Skills

Use this skill to show the repo-local specdrive Codex skills available in this repository.

Read First

Read this registry first:

.agents/skills/specdrive-skills/skills.json

Use the registry command and description values for the displayed list.

If the registry is missing or invalid, fall back to reading the SKILL.md files under:

.agents/skills/*/SKILL.md

In the fallback path, use each skill's frontmatter name and description.

Output

Reply with a concise list using this shape:

$skill-name - short description

Keep the descriptions short and user-facing.

Boundaries

  • Do not edit files.
  • Do not install global skills.
  • Do not include system skills unless the user explicitly asks for them.
  • Do not perform the listed skills; only list them.
  • Treat skills.json as display metadata; each SKILL.md remains the execution source.
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
