SPEC-based development interview -- generates a detailed SPEC.md specification through in-depth questioning.

  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Spec is an agent skill from jh941213/my-cc-harness. SPEC-based development interview -- generates a detailed SPEC.md specification through in-depth questioning. Triggers on: spec, spec, specification, interview, feature design. NOT for: immediate implementation, simple fixes, code writing.

Its SKILL.md is about 660 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

Example prompts

  • “/spec”

Requirements

  • Pre-approved tools (allowed-tools): Read, Write, Edit, AskUserQuestion

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Check or Create SPEC.md
  2. In-Depth Interview
  3. Question Rules
  4. Specification Writing
  5. Guidance

What it can do on your machine

Read from SKILL.md and the folder at commit e9210e2. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • AskUserQuestion

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    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

Spec loads about 661 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 215 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~61
When it runs · the whole SKILL.md, loaded when a task matches
~661

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 215 words (~661 tokens).
