What it does

Spk Mission Documentation is an agent skill from spec-kitty/spec-kitty. Operate documentation-oriented Spec Kitty missions and ensure docs stay tied to shipped behavior and doctrine.

Its SKILL.md is about 200 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development. The repository describes itself as: Spec-Driven Development with organizational governance. Specs tell AI agents what to build; Charter governs how they build it. Git-native missions, enforceable workflows, and… The licence is MIT.

When your agent uses it

  • Development work in your project

Example prompts

  • “/spk-mission-documentation”

Workflow steps

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

  1. Confirm whether this is a documentation mission or a software mission with
  2. Ground docs in current product behavior, not intended future behavior unless
  3. Cross-check terms with spk-doctrine-glossary.
  4. If docs describe commands or workflows, cross-check spk-start-command-map.

What it can do on your machine

Read from SKILL.md and the folder at commit e533131. 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

Spk Mission Documentation loads about 202 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 84 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~34
When it runs · the whole SKILL.md, loaded when a task matches
~202

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.

description
Operate documentation-oriented Spec Kitty missions and ensure docs stay tied to shipped behavior and doctrine.

spk-mission-documentation

Use this skill when the mission is primarily documentation, release notes, guides, or user-facing explanation.

Flow

  1. Confirm whether this is a documentation mission or a software mission with docs as acceptance criteria.
  2. Ground docs in current product behavior, not intended future behavior unless clearly marked.
  3. Cross-check terms with spk-doctrine-glossary.
  4. If docs describe commands or workflows, cross-check spk-start-command-map.

Completion Standard

Documentation should make the next user action obvious and should not create a second source of truth for runtime behavior.
