What it does
API Documentation is an agent skill from revfactory/claude-code-harness. Write accurate and complete library API documentation. Use when creating API docs, README files, or function reference documentation. Ensures all signatures, parameters, return types, and examples are precise.
Its SKILL.md is about 260 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/format-tokens.md`).
It sits in Development, covering Technical documentation.
When your agent uses it
- Creating API docs
- Function reference documentation
Example prompts
- “/api-documentation”
Workflow steps
6 steps, taken from the first numbered list in SKILL.md.
- 소스 코드에서 모든 public 함수 시그니처 추출
- 각 함수의 파라미터 (필수/선택) 및 반환값 타입 확인
- 함수 문서 템플릿에 맞춰 작성
- format 토큰 등 열거형 값은 전수 나열
- 예제 코드는 실제 동작과 일치하도록 작성
- 정확성 체크리스트로 최종 검증
What it can do on your machine
Read from SKILL.md and the folder at commit 267005c. 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 (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
API Documentation loads about 263 tokens when it runs, and up to ~548 if it reads all its reference files. Until then it costs about 57 tokens; SKILL.md has 85 words of instructions outside code blocks.
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 85 words (~263 tokens).

Questions about API Documentation
What does API Documentation do?
Write accurate and complete library API documentation. An agent skill from revfactory/claude-code-harness. API Documentation is an agent skill from revfactory/claude-code-harness. Write accurate and complete library API documentation.
When should I use API Documentation?
API Documentation fits situations like: creating API docs; function reference documentation.
How do I install API Documentation in Claude Code?
Run `npx skills add revfactory/claude-code-harness --skill api-documentation -a claude-code`. Or copy the skill folder (experiments/results/case-004/harness/.claude/skills/api-documentation in revfactory/claude-code-harness) into .claude/skills/api-documentation in your project. Claude Code loads it when a task matches its description.
How do I install API Documentation in Codex?
Run `npx skills add revfactory/claude-code-harness --skill api-documentation -a codex`. Or copy the skill folder (experiments/results/case-004/harness/.claude/skills/api-documentation in revfactory/claude-code-harness) into .agents/skills/api-documentation in your project. Codex loads it when a task matches its description.
Can I use API Documentation in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add revfactory/claude-code-harness --skill api-documentation -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/api-documentation, .gemini/skills/api-documentation, .github/skills/api-documentation and .opencode/skills/api-documentation in your project.
What does API Documentation need to run?
SKILL.md names no scripts, command-line tools or credentials: API Documentation is instructions for the agent only.
Does API Documentation access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is API Documentation safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does API Documentation use?
No licence was found for API Documentation or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does API Documentation use?
About 263 tokens (SKILL.md is roughly 1.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 285 tokens, read only when the agent opens those files.
