Jamdesk Docs

Use when user-facing code changes need documentation — after implementing APIs, CLI commands, UI components, or config options. Triggers on 'update docs', 'document this', 'add to jamdesk docs', 'write docs', 'docs are outdated', 'the docs don't mention X', or any request to create/update Jamdesk documentation pages. Also use proactively after feature work that changes user-facing behavior, even if the user doesn't explicitly ask for docs — suggest it.

Update Jamdesk

Updates customer-facing documentation in external repositories (not CLAUDE.md). Locates docs via .jamdesk-docs-path, asks clarifying questions, writes documentation, and verifies with the jamdesk CLI. Learn more about Jamdesk on the Jamdesk homepage.

Announce: "I'm using the update-jamdesk skill to update your documentation."

Use when: User-facing changes to APIs, CLI commands, UI, config options, component behavior, or docs.json schema/features.

Skip when: Internal refactors, test-only changes, build/CI config, performance work without behavior change.

Right-size it: Not every change deserves a new page — a renamed config key is one edited line in an existing page, not a new doc.

Common mistake: Changes to docs.json format or config handling are user-facing. Even if the change was made inside the docs repo itself, ask: "Does this introduce or change a config pattern that customers use?" If yes, document it.

Critical Rules

Always	Never
Include frontmatter (title ≤ 60 chars, description 120-160 chars)	Create stub pages with "TODO"
Use built-in components first	Use mint.json (use docs.json)
Ask clarifying questions before writing	Skip verification
State prerequisites up front	Include secrets, tokens, or real customer data
Use active voice and action-oriented headings	Promise guarantees ("always works", "instant")
Include explicit warnings for destructive steps	Use "click here" link text

Flags

Flag	Behavior
(none)	Full workflow: locate → clarify → analyze → write → verify → commit
--preview	Phases 1-3 only, describe changes without making them. Skip first-time config creation (report what you would create) and the branch-strategy question

Phase 1: Locate Documentation

Find .jamdesk-docs-path by walking up from current directory to git root. It is a YAML file that lives at the git root of the code repo:

yaml

docs_path: ../customer-docs    # Required - relative or absolute path
docs_branch: main              # Optional - base branch for new feature branches, default: main

First-time setup: If config doesn't exist, ask user for their docs repo path and create the file at the git root. This only happens once per project. Point users to https://jamdesk.com/docs for help getting started with Jamdesk.

Preflight checks — resolve each failure before writing anything:

Check	On failure
docs_path exists	Re-ask the user for the path, update the config
Contains docs.json	If only mint.json exists, stop — tell the user to migrate to docs.json first
which jamdesk	CLI missing — continue, but use the manual verification checklist in Phase 5
Docs working tree is clean	Stop and ask: stash, commit existing work, or proceed anyway. Never proceed silently onto a dirty tree

Same-repo docs: If the docs live in the same git repo as the code, skip separate git operations entirely — stay on the current branch, include doc changes alongside the code change, and skip the branch-strategy question (Phase 2) and the commit menu (Phase 6).

Phase 2: Clarify Scope

Review conversation to identify what changed, then ask:

1. Branch strategy (external docs repo only — skip if same-repo): Feature branch created from docs_branch (recommended), main, or current branch? If an unmerged docs branch from a previous run exists, surface it instead of silently creating a second one.
2. Scope confirmation: "I plan to [create/update] these pages: ... Any changes?"
3. Additional context (if needed): Terminology, related features, edge cases

Principle: Ask first, write later. 30-second clarification prevents 10-minute rework.

Phase 3: Analyze Existing Docs

Search docs repo for existing coverage of the feature. Present findings:

text

Existing: getting-started.mdx mentions feature briefly
Missing: No dedicated page

Recommended:
1. Create: features/new-feature.mdx
2. Update: getting-started.mdx (add link)

Decision matrix:

Scenario	Action
New feature	Create new page
Behavior change	Update existing page describing that behavior
Small addition	Add section to existing page
Major capability	New standalone page
Deprecation/removal	Update existing + add migration notes
Advanced usage	Add <Accordion> to existing page (keeps the page scannable for beginners)
New docs.json config/pattern	Update docs.json reference and/or navigation docs

Phase 4: Write Documentation

The rules below are the load-bearing standards — fetch https://jamdesk.com/docs only if you need something not covered here.

Content quality:

• Explain why, not just what
• Show the simplest working example first
• Use concrete, realistic values in examples, not placeholders (readers learn faster from examples they can copy-paste) — but anything secret-shaped (API keys, tokens, passwords) must be obviously fake, e.g. sk_test_xxxx
• Show expected output after commands so readers can confirm they're on track
• One concept per section, 3-7 subsections per page
• Define terms once and reuse consistently

Writing quality:

• Active voice, direct instructions
• Short sentences, avoid idioms (global audiences)
• Action-oriented headings ("Configure X", "Verify Y", "Troubleshoot Z")
• Descriptive link text (never "click here")
• Include <Warning> for destructive/irreversible steps
• No description echo: The opening paragraph MUST say something different from the frontmatter description. The description is for SEO meta tags; the opening paragraph should complement it with context, prerequisites, or what the reader will accomplish -- not repeat it.

Page structure:

1. Opening paragraph (what + why + target audience)
2. Prerequisites (tools, access, versions)
3. Quick Start (simplest example)
4. Configuration/Details
5. Examples (basic → advanced)
6. Troubleshooting (optional — common errors and fixes; errors hit while building the feature are good candidates)
7. What's Next (2-4 related links)

Page types:

• Task pages: Step-by-step procedure with numbered steps
• Reference pages: Minimal example first, then expand with details
• Concept pages: Explain how something works and why (architecture, mental models) — link to task pages for the steps

Heading structure: Single H1 (page title in frontmatter), body sections start at H2.

Minimal template:

mdx

---
title: Feature Name
description: SEO description (120-160 chars, unique per page)
lastUpdated: YYYY-MM-DD  # Optional, for frequently-changing features - replace with today's actual date
---

What this does and why it's useful. Target audience: developers who need X.

## Prerequisites

- Node.js 18+
- API key from [Settings](/settings)

## Quick Start

\`\`\`bash
command --example
\`\`\`

## What's Next?

<Columns cols={2}>
  <Card title="Related Feature" href="/related">
    Continue with this
  </Card>
  <Card title="API Reference" href="/api">
    Full API details
  </Card>
</Columns>

Components: <Tabs>, <Steps>, <Accordion>, <Columns>, <Card>, <Note>/<Warning>/<Tip>, <CodeGroup>. There is no <Cards> component -- use <Columns cols={2}> with <Card> children. If you need a component not listed here, check https://jamdesk.com/docs/components

Images: Add screenshots when they aid understanding (UI walkthroughs, visual states) — skip them when text or code alone is clear. Store in /images/<feature>/, use absolute paths, always include alt text, avoid color-only cues.

Links: Relative paths, no .mdx extension, avoid orphan pages, link to source of truth (API spec, release notes).

API docs: Prefer OpenAPI auto-generation when available.

Navigation: Add new pages to docs.json navigation in alphabetical order unless the user has specified a different ordering or the existing structure suggests intentional grouping.

Maintenance: Use lastUpdated frontmatter for frequently-changing features. Mark or remove deprecated guidance promptly.

Phase 5: Verify

With CLI (recommended):

bash

jamdesk validate     # Check docs.json schema
jamdesk broken-links # Find broken links

jamdesk dev starts a long-running local preview server — never run it in the foreground yourself. Offer it to the user for a visual check, or run it as a background command.

Without CLI (detected in Phase 1 preflight): Verify manually - code examples have language tags, frontmatter has title/description, links use correct paths (no .mdx), new pages added to docs.json.

Test code examples: Run commands and snippets where feasible before publishing — broken copy-paste examples are the most common docs complaint.

Fix errors before proceeding. If the user dislikes the changes, revert only the files this skill touched: git checkout -- <files you wrote>. Never suggest git checkout . — it discards all uncommitted work, including changes the user had in progress.

Phase 6: Commit

Same-repo docs: Skip this menu — the doc changes ride along with the code change's normal commit flow.

External docs repo: Present summary of changes, then ask user preference:

1. Commit to feature branch
2. Show diff first
3. Make additional changes

After commit, offer to push and create PR.

Commit format: docs: [action] [what] (e.g., docs: add webhook configuration guide)

Quick Reference

Situation	Action
No config file	Ask user, create .jamdesk-docs-path
External repo	Feature branch, separate git ops
Same-repo docs	No separate git ops needed
--preview flag	Analyze only, no changes
CLI unavailable	Manual verification checklist
