Create Doc Skill for Claude
Use when the user wants to save knowledge as a file so others don't have to rediscover it — \"turn this into a doc\", \"write this up\", \"document how X works\", \"we figured this out and want to capture it\", \"nobody should have to figure this out again\". Covers any request to create or update durable written artifacts: onboarding guides, runbooks, ADRs, API docs, architecture notes, postmortems, changelogs, setup guides. The trigger: user wants knowledge captured in a file for future reference, not just a conversation. Do NOT use when still making decisions (→ give-plan), just asking for explanation without a file (→ ask), or writing code (→ cook).

Process
Check conversation context and skip completed steps.
1. Identify the doc job
Figure out the document type, audience, purpose, whether to update an existing doc or create new, and what source material it draws from. If any of these would materially change the output and are unclear, ask.
If the request is still evaluating options, stop and discuss — drafting docs before a decision is made locks in the wrong answer.
If the doc type is a recognized structured format (runbook, ADR, postmortem, onboarding guide, API/architecture doc), read references/doc-types.md now — it has the required sections for each type.
2. Ground in evidence
Before writing factual claims, read relevant sources — existing docs, code, config, tickets, PRs, prior discussion. Don't present guesses as fact. Label uncertain details explicitly, or collect them in an "Open questions" section rather than hedging every sentence.
3. Choose destination
Prefer updating the canonical existing doc when one exists.
For new documents, MUST default to docs/ at the repo root (create it if missing). Only deviate when:
- A more specific existing doc home clearly fits (ADR directory, changelog, README section, established project docs tree) — use it
- The repo already follows a convention of keeping docs next to the code they explain — match that
- The doc is event-like (postmortem, incident note) — use a timestamped filename
When you need a fresh timestamp, use date +%Y%m%d%H%M%S.
4. Outline first when substantial
For large or structurally ambiguous docs, propose a title and section outline before drafting. For small or routine docs, write directly.
5. Write the artifact
Write the file at the path from Step 3 — don't paste in chat without creating the file. Adapt structure to the document type (ADRs, runbooks, postmortems, API docs, etc.) and include only sections that earn their keep.
A strong document is accurate, concise, audience-aware, scannable, explicit about *why* something matters, and clear about what is current behavior vs. decision vs. open question. Write for the intended reader, not for completeness theater. Prefer concrete repo-specific details over generic filler. When sources conflict, name the conflict instead of quietly picking one.
6. Report and stop
Report the path, whether you updated or created, what was captured, and any assumptions or gaps. Do not drift into implementation unless explicitly asked.

Convert Markdown files to HTML similar to `marked.js`, `pandoc`, `gomarkdown/markdown`, or similar tools; or writing custom script to convert markdown to html and/or working on web template systems like `jekyll/jekyll`, `gohugoio/hugo`, or similar web templating systems that utilize markdown documents, converting them to html. Use when asked to "convert markdown to html", "transform md to html", "render markdown", "generate html from markdown", or when working with .md files and/or web a templating system that converts markdown to HTML output. Supports CLI and Node.js workflows with GFM, CommonMark, and standard Markdown flavors.
Write and maintain technical documentation. Trigger with "write docs for", "document this", "create a README", "write a runbook", "onboarding guide", or when the user needs help with any form of technical writing — API docs, architecture docs, or operational runbooks.
Translate visa application documents (images) to English and create a bilingual PDF with original and translation
Write, review, and edit documentation files with consistent structure, tone, and technical accuracy. Use when creating docs, reviewing markdown files, writing READMEs, updating `/docs` directories, or when user says "write documentation", "review this doc", "improve this README", "create a guide", or "edit markdown". Do NOT use for code comments, inline JSDoc, or API reference generation.
Real-time Constitution compliance checker for devflow documents. Blocks partial implementations and hardcoded secrets during file editing.
Write self-documenting code with minimal, evergreen comments that explain complex logic without describing recent changes or temporary fixes. Use this skill when writing code comments, documentation strings, explaining complex algorithms, clarifying business logic, or deciding whether code needs comments. Apply when working with any source code files where comments or documentation might be added, ensuring comments remain relevant, helpful, and focused on explaining why rather than what the code does, while preferring clear code structure and naming over excessive commenting.
Use when writing technical documentation that needs to be readable by both humans and AI models, converting existing docs to HADS format, validating a HADS document, or optimizing documentation for token-efficient AI consumption.
Draft a structured investment committee memo for PE deal approval. Synthesizes due diligence findings, financial analysis, and deal terms into a professional IC-ready document. Use when preparing for investment committee, writing up a deal, or creating a formal recommendation. Triggers on "write IC memo", "investment committee memo", "deal write-up", "prepare IC materials", or "recommendation memo".
