What it does

Bug Repro Plan is an agent skill from proflead/codex-skills-library. Create a minimal, repeatable reproduction plan for a bug. Use when a junior developer needs clear steps to reproduce and capture evidence.

Its SKILL.md is about 220 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Codex Skills Library is a curated library of reusable Codex skills for developers, individuals, and teams.

When your agent uses it

  • A junior developer needs clear steps to reproduce and capture evidence

Example prompts

  • “/bug-repro-plan”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Ask for environment details and exact versions.
  2. List numbered steps to reproduce with inputs and preconditions.
  3. Record expected vs actual behavior and any logs or screenshots.
  4. Suggest a minimal test or script to lock the repro.

What it can do on your machine

Read from SKILL.md and the folder at commit a05260c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Bug Repro Plan loads about 219 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 98 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~38
When it runs · the whole SKILL.md, loaded when a task matches
~219

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 98 words (~219 tokens).
