Shipkit claude md

shipkit-claude-md

Update CLAUDE.md so future sessions and subagents automatically inherit learnings and context.

---

When to Invoke

Explicit triggers:

• /claude-md <content> — with inline content
• /claude-md — prompts for what to add
• /shipkit-claude-md

Natural language triggers:

• "Update CLAUDE.md"
• "Add to CLAUDE.md"
• "Update my claude md"
• "Remember this"
• "Save this for next time"

Important: Never auto-suggest. Only act when user explicitly requests persistence.

---

Prerequisites

Required:

• Root CLAUDE.md exists (installed by Shipkit)
• CLAUDE.md has ## Working Preferences and ## Project Learnings sections

Optional:

• Subfolder CLAUDE.md files for folder-specific learnings

Important distinction:

• CLAUDE.md → User-editable (preferences, learnings) — THIS skill edits this file
• .claude/rules/shipkit.md → Framework-managed (skills reference, core rules) — DO NOT edit

---

Process

Step 1: Get the Learning

If invoked with content:

/teach use date-fns instead of moment.js

→ Learning = "use date-fns instead of moment.js"

If invoked without content:

/teach

→ Ask: "What would you like me to remember?"

Step 2: Classify Type

Learning About...	Type	Target Section
How Claude behaves	Style	## Working Preferences
Code patterns/libraries	Technical	## Project Learnings

Examples:

• "Be more concise" → Style → Working Preferences
• "Use date-fns not moment" → Technical → Project Learnings
• "Always confirm before deleting" → Style → Working Preferences
• "API returns {data:[]} wrapper" → Technical → Project Learnings

Step 3: Determine Scope

Check for existing CLAUDE.md files:

Glob("**/CLAUDE.md")

Present options:

Where should this apply?

  [1] Project-wide (root CLAUDE.md)
  [2] frontend/ (frontend/CLAUDE.md)
  [3] Other path: ___

If user picks a folder without CLAUDE.md, offer to create one.

Step 4: Read Target File

Read(<path>/CLAUDE.md)

Find the target section:

• For Style → find ## Working Preferences
• For Technical → find ## Project Learnings

Step 5: Check for Duplicates

Scan existing learnings in the section. If similar exists:

Similar learning already exists:
  - "Prefer date-fns over moment"

  [1] Skip (already covered)
  [2] Add anyway (more specific)
  [3] Replace existing

Step 6: Append Learning

Add new bullet to the end of the target section.

Before:

## Project Learnings

- Use date-fns instead of moment.js

After:

## Project Learnings

- Use date-fns instead of moment.js
- API responses wrap data in { data: [] }

Step 7: Confirm

Added to CLAUDE.md → Project Learnings:
  - API responses wrap data in { data: [] }

This will apply to all future sessions.

If folder-specific:

Added to frontend/CLAUDE.md → Project Learnings:
  - Use Tailwind instead of CSS modules

This will apply when working in frontend/.

---

Creating Subfolder CLAUDE.md

If user wants folder-specific learning but no CLAUDE.md exists:

No CLAUDE.md found in frontend/. Create one?

  [1] Yes, create frontend/CLAUDE.md
  [2] Add to root CLAUDE.md instead

If yes, create minimal structure:

# Frontend

Frontend-specific context and learnings.

---

## Working Preferences

<!-- Style preferences for frontend work -->

---

## Project Learnings

<!-- Frontend-specific patterns and corrections -->

Then append the learning.

---

Important Rules

1. Never auto-suggest — Don't ask "Should I remember this?" Only act when user explicitly requests
2. Always confirm — Show what was added and where
3. Respect structure — Append to existing sections, don't reorganize
4. Check duplicates — Avoid redundant entries
5. Never edit .claude/rules/ — Framework rules are managed by /shipkit-update, not this skill

---

Removing Learnings

No special handling needed. User says:

Remove the learning about moment.js

Claude reads CLAUDE.md, finds the line, removes it, confirms.

When This Skill Integrates with Others

Before This Skill

Skill	Relationship
Any skill	User may want to persist a learning discovered during any workflow

After This Skill

Skill	Relationship
All future sessions	Learnings auto-loaded via CLAUDE.md
Subagents in subfolders	Folder-specific learnings auto-loaded via lazy loading

Related Skills

Skill	Relationship
/shipkit-project-context	Reads CLAUDE.md; teach writes to it
/shipkit-codebase-index	Different purpose (structure vs. learnings)

---

Context Files This Skill Reads

File	Purpose
CLAUDE.md	Root project instructions (find target section)
<folder>/CLAUDE.md	Subfolder instructions (if folder-specific)
**/CLAUDE.md	Glob to find existing CLAUDE.md files for scope options

---

Context Files This Skill Writes

File	Action
CLAUDE.md	Append to ## Working Preferences or ## Project Learnings
<folder>/CLAUDE.md	Create if needed, append learning

Write Strategy: APPEND-ONLY to existing sections. Never reorganize or overwrite.

<!-- SECTION:after-completion -->

After Completion

Confirm to user:

• What learning was added
• Which section (Working Preferences or Project Learnings)
• Which file (root or subfolder CLAUDE.md)
• When it takes effect (all future sessions, or when working in folder)

No follow-up skill needed — learnings are immediately active for current session and persist to future sessions.

<!-- SECTION:success-criteria -->

Success Criteria

• Learning captured from user
• Type classified (Style vs Technical)
• Scope determined (root vs folder)
• Duplicates checked
• Learning appended to correct section
• User confirmed what was added and where
