What it does

Writing Docs is an agent skill from c15t/c15t. Author or edit c15t documentation in docs//.mdx — the source for both the c15t.com site and the docs bundled into published packages. Use when writing guides, integration pages, reference docs, changing package-bundled docs (packages//docs, packages//AGENTS.md), or fixing docs lint failures.

Its SKILL.md is about 870 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 Agent Workflows, covering Markdown, Linting and formatting and Agent instruction files. It works with React and Next.js. The repository describes itself as: The Developer-First Cookie Banner. The licence is Apache-2.0.

When your agent uses it

  • Integration pages
  • Changing package-bundled docs (packages//docs
  • Packages//AGENTS.md)
  • Fixing docs lint failures

Example prompts

  • “/writing-docs”

Workflow steps

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

  1. c15t.com — the docs site app is private and maintainer-only. External contributors only edit MDX and preview via the PR docs-preview action.
  2. Package-bundled docs — scripts/generate-package-docs.ts compiles subsets of docs/ into a docs/ folder and AGENTS.md for six packages…

What it can do on your machine

Read from SKILL.md and the folder at commit f2b2318. 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:

    • bun

    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

Writing Docs loads about 872 tokens when it runs. Until then it costs about 78 tokens; SKILL.md has 360 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~78
When it runs · the whole SKILL.md, loaded when a task matches
~872

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
Author or edit c15t documentation in docs/**/*.mdx — the source for both the c15t.com site and the docs bundled into published packages. Use when writing guides, integration pages, reference docs, changing package-bundled docs (packages/*/docs, packages/*/AGENTS.md), or fixing docs lint failures.

Writing c15t Docs

docs/ is the single source of truth for two outputs:

  1. c15t.com — the docs site app is private and maintainer-only. External contributors only edit MDX and preview via the PR docs-preview action.
  2. Package-bundled docs — scripts/generate-package-docs.ts compiles subsets of docs/ into a docs/ folder and AGENTS.md for six packages (c15t, @c15t/react, @c15t/nextjs, @c15t/backend, @c15t/scripts, @c15t/cli), which ship in their npm tarballs.

Never edit packages/*/docs/** or packages/*/AGENTS.md directly — they are generated. Edit the MDX source, then regenerate with bun run generate:package-docs (or bun run --cwd packages/<pkg> build:docs).

The docs pipeline (generation, docs/docs.config.ts, MDX components, lint schema) is built on leadtype — use the leadtype skill for its components, config, conversion, and lint APIs rather than guessing.

Where content lives

DirectoryFeeds
docs/frameworks/{javascript,react,next,...}/Framework quickstarts and guides; javascript→c15t, react→@c15t/react, next→@c15t/nextjs bundled docs
docs/shared/Content reused across frameworks; bundled into core/react/nextjs
docs/integrations/GTM, GA4, PostHog, Meta Pixel, etc.; bundled into core/react/nextjs/scripts
docs/self-host/Bundled into @c15t/backend
docs/cli/Bundled into @c15t/cli
docs/oss/, docs/contributing/, docs/legals/, docs/comparisons/Site only

Navigation, groups, and page ordering are defined in docs/docs.config.ts. New pages usually need an entry there (see the leadtype skill for the config schema).

MDX rules

  • Frontmatter is required: title and description. The description doubles as the intro paragraph.
  • Never start with an H1 — the frontmatter title renders as the page H1. Begin content at ## and nest properly (H2 → H3 → H4).
  • Use <Callout> for warnings/notes and <PackageCommandTabs command="..." /> / package-install code blocks for install commands so all package managers render.
  • Fenced code blocks always carry a language identifier.
  • Lists use - bullets (remark enforces consistency).

Style

  • Simple, direct, active voice; second person ("you"). Define jargon and acronyms on first use, then stay consistent (don't mix "endpoint" and "route").
  • Show working code before explaining it. Every key concept gets a runnable snippet.
  • Match the document type: tutorials are sequential and confirm success at each step ("You should now see…"); how-to guides are numbered steps that assume the basics; reference pages are exhaustive, scannable, and neutral; explanations discuss trade-offs and may be opinionated ("We recommend X because…").
  • Be honest about limitations ("works well for small datasets, but…").

Verify

bash
bun run lint:docs   # remark lint (MDX + frontmatter + consistency)
bun run fmt:docs    # remark autoformat
bun run generate:package-docs   # refresh packages/*/docs and AGENTS.md if your pages are bundled

CI's autofix workflow also runs fmt:docs and commits fixes to your branch.
