What it does
Jsdocs is an agent skill from foldkit/foldkit. Public API JSDoc. Use when authoring or reviewing Effect API documentation, refining a module's documentation, or fixing documentation related diagnostics.
Its SKILL.md is about 450 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `categories.md`, `declarations.md` and `examples.md`).
It sits in Development, covering Technical documentation. The licence is MIT.
When your agent uses it
- Reviewing Effect API documentation
- Refining a modules documentation
- Fixing documentation related diagnostics
Example prompts
- “/jsdocs”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Inspect the declaration, implementation, nearby JSDoc, tests, and call sites.
- Select every applicable branch and load its reference before editing
- Make a focused API fix or module refinement. Preserve verified facts and
- For module refinement or APIs with close alternatives, audit @see links
- Run pnpm jsdocs --check and every applicable root validation command.
What it can do on your machine
Read from SKILL.md and the folder at commit 49dc36e. 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
Shell commands in SKILL.md call:
pnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pnpm, which can reach the network depending on how they are called.
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
Jsdocs loads about 445 tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 207 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.

Workflow
- Inspect the declaration, implementation, nearby JSDoc, tests, and call sites.
- Select every applicable branch and load its reference before editing:
- tags, modules, or links: declarations.md;
- categories: categories.md;
- examples: examples.md.
- Make a focused API fix or module refinement. Preserve verified facts and valuable examples rather than rewriting mechanically.
- For module refinement or APIs with close alternatives, audit
@seelinks and inspect implementation and tests for concrete**Gotchas**. - Run
pnpm jsdocs --checkand every applicable root validation command.
@internal declarations and default exports are outside public JSDoc
authoring. Checked files do not support exported enums or empty export
declarations.
Public declarations use a multiline block with one self-contained practical
description paragraph. Start functions and methods with a present-tense action;
match nearby noun-family phrasing for values. Optional non-empty sections appear
once in this order: **When to use**, **Details**, **Gotchas**. Separate
descriptions, sections, examples, and tags with one blank line. **When to use** states a positive use case distinct from the description; reserve
**Gotchas** for concrete caveats and failure modes.
The task is complete when every changed public declaration satisfies each applicable reference, the checker passes, runnable examples pass their targeted doctest, and all other applicable root checks pass or are reported as not run.
