What it does
Reference Builder is an agent skill from aiskillstore/marketplace. Creates exhaustive technical references and API documentation. Generates comprehensive parameter listings, configuration guides, and searchable reference materials. Use PROACTIVELY for API docs, configuration references, or complete technical specifications.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `skill-report.json`).
It sits in Development, covering Technical documentation. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
When your agent uses it
- Tasks that involve Technical documentation
Example prompts
- “Use the reference-builder skill to create exhaustive technical references and API documentation”
- “/reference-builder”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Exhaustive Coverage: Document every parameter, method, and configuration option
- Precise Categorization: Organize information for quick retrieval
- Cross-Referencing: Link related concepts and dependencies
- Example Generation: Provide examples for every documented feature
- Edge Case Documentation: Cover limits, constraints, and special cases
What it can do on your machine
Read from SKILL.md and the folder at commit ad8daf7. 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
Reference Builder loads about 1.3k tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 497 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 497 words (~1,326 tokens).
“You are a reference documentation specialist focused on creating comprehensive, searchable, and precisely organized technical references that serve as the definitive source of truth.”
