What it does

Repo Harness Product is an agent skill from Ancienttwo/repo-harness. Draft requested product requirements, order a Sprint backlog, or prepare a native Goal session. Exclude ordinary code tasks.

Its SKILL.md is about 210 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/goal.md`, `references/prd.md` and `references/sprint.md`).

It sits in Product & Project Management, covering PRD writing. The repository describes itself as: File-backed workflow harness for reliable Claude Code and Codex sessions. The licence is MIT.

When your agent uses it

  • Tasks that involve PRD writing

Example prompts

  • “/repo-harness-product”

What it can do on your machine

Read from SKILL.md and the folder at commit 461e054. 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

Repo Harness Product loads about 208 tokens when it runs, and up to ~5.2k if it reads all its reference files. Until then it costs about 36 tokens; SKILL.md has 79 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~36
When it runs · the whole SKILL.md, loaded when a task matches
~208
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5.2k

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.

when_to_use
repo-harness-product

repo-harness-product

Bot entrypoint. Confirm the product goal and source requirements.

Mode Selection

  • A real new product needs a PRD: references/prd.md.
  • A requested backlog needs ordering: references/sprint.md.
  • A requested bounded Goal session needs preparation: references/goal.md.

Boundaries

Use a short worker brief or PR description for ordinary tasks. Do not mark artifacts Approved on the user's behalf. Preserve existing approval. Keep tasks/todos.md as the deferred-goal ledger. Product planning does not install ChatGPT or execute backlog work. Delegate execution within named scope.
