API document writing tablelevel and pattern library. An agent skill from revfactory/harness-100.

  • Tasks that involve Technical documentation
  • SKILL.md covers REST API document required…, endpoint document template, error tablelevel and HTTP status code mapping, plus 5 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Tasks that involve OpenAPI specifications

What it does

API Doc Standards is an agent skill from revfactory/harness-100. API document writing tablelevel and pattern library. doc-writer agent REST/GraphQL/gRPC API document writingto do when reference tablelevel. 'API document tablelevel', 'API reference writing' request when usage. However, OpenAPI Spec specialist creation API test execution scope outside.

Its SKILL.md is about 920 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 Backend & APIs, covering Technical documentation, OpenAPI specifications and gRPC and Protobuf. It works with gRPC, OpenAPI and GraphQL. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Technical documentation
  • Tasks that involve OpenAPI specifications
  • Tasks that involve gRPC and Protobuf

Example prompts

  • “API document tablelevel”
  • “API reference writing”
  • “/api-doc-standards”

What it can do on your machine

Read from SKILL.md and the folder at commit 8e8d35c. 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 and json).

    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 Doc Standards loads about 915 tokens when it runs. Until then it costs about 76 tokens; SKILL.md has 184 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~76
When it runs · the whole SKILL.md, loaded when a task matches
~915

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.
