## framework-upgrade

Upgrades the Exosuit framework to a newer version while preserving all project-specific customizations (skills, rules, hooks, settings).

### Phase 0: Validate & Discover

1. **Fetch new framework version:**
   - **Default (no argument or `--branch <branch>`):** Clone the framework repo from GitHub into a temp directory. Use `main` branch unless `--branch` specifies otherwise.
     ```bash
     FRAMEWORK_REPO="https://github.com/joris887/exosuit.git"
     TEMP_DIR=$(mktemp -d)
     git clone --depth 1 [--branch <branch>] "$FRAMEWORK_REPO" "$TEMP_DIR"
     ```
   - **Local path override:** If `$ARGUMENTS` is a directory path, use it directly (for testing local changes before pushing).
   - **Validate:** The source (cloned or local) must contain `.claude/skills/`, `.claude/hooks/`, `CLAUDE.md`.
1. **Current version** — Read `SKILLS_INVENTORY.md`, extract `Framework Version:` line. Record as `CURRENT_VERSION`.
1. **New version** — Read `<source>/CHANGELOG.md` or `<source>/.claude/skills/SKILLS_INVENTORY.md` for version. Record as `NEW_VERSION`.
1. **Git safety** — Verify working tree is clean (`git status --porcelain`). If dirty, HALT: "Commit or stash changes before upgrading."
1. **Report**: "Upgrading framework: v{CURRENT} → v{NEW}. Source: {GitHub main | GitHub branch | local path}. Branch: {branch}."
1. **Parse Version Log:**

   Read `CHANGELOG.md` from the new framework version. Find all version entries between `CURRENT_VERSION` and `NEW_VERSION`.

   For each version entry, collect:
   - `CORE_REPLACE` files — will be replaced automatically
   - `CORE_MERGE` files — will be merged (preserve project-specific sections)
   - `PROJECT_UPDATE_INSTRUCTIONS` — manual steps for project-specific files

   Also read `core/MANIFEST.md` from the new framework version for file classification reference.

   Present a targeted upgrade plan based on the changelog:

   ```markdown
   ## Targeted Upgrade: v{CURRENT} → v{NEW}

   ### Automatic (CORE files to replace/add)
   - [file]: [new/changed] (from version X.Y.Z)

   ### Merge Required (CORE files with project sections)
   - [file]: [what to merge] (from version X.Y.Z)

   ### Manual Steps (project-specific updates)
   - [instruction from PROJECT_UPDATE_INSTRUCTIONS] (from version X.Y.Z)
   ```

   This targeted plan supplements the full inventory in Phase 1. If `CHANGELOG.md` does not contain the structured `CORE_REPLACE`/`CORE_MERGE` blocks (older versions), fall back to Phase 1's full diff-based inventory.
1. **Cleanup note**: If a temp directory was created, delete it at the end of Phase 3 (after verification).

### Phase 1: Inventory & Classify

Run 4 parallel exploration agents to build a complete diff inventory:

**Agent 1 — Skills diff**: Compare `.claude/skills/` between current and new. For each skill directory:

- EXISTS IN BOTH → check SKILL.md + references/ for content differences → classify as `UPDATE` or `IDENTICAL`
- ONLY IN NEW → classify as `ADD`
- ONLY IN CURRENT → classify as `PRESERVE` (project-specific)

**Agent 2 — Hooks diff**: Compare `.claude/hooks/` (*.sh, rules/*.patterns, rules/*.conf, *.json, lib/). Classify each file.

**Agent 3 — Agents + Prompts + Commands diff**: Compare `.claude/agents/`, `.claude/prompts/`, `.claude/commands/`. Classify each file.

**Agent 4 — Rules + Docs diff**: Compare `.claude/rules/`, `docs/reference/` (TESTING_STRATEGY, MCP_INTEGRATION, CODING_STANDARDS, GROUND_RULES, GIT_WORKFLOW, WORKFLOW), `docs/context/` template structure, `scripts/pm/`, `llms.txt`.

Compile results into a structured upgrade plan:

```
## Upgrade Plan: v{CURRENT} → v{NEW}

### REPLACE (take new version as-is)
- [file]: [reason]

### MERGE (new framework + project customizations)
- [file]: [what to preserve from current]

### ADD (new files from framework)
- [file]: [purpose]

### PRESERVE (project-specific, no changes)
- [file]: [reason]

### POPULATE (templates that need project content)
- [file]: [what content to write]
```

<HARD-GATE>
Present the upgrade plan to the user. Do NOT proceed until they approve.
Ask: "Approve this upgrade plan? I'll preserve all project-specific customizations listed under PRESERVE."
</HARD-GATE>

### Phase 2: Execute Upgrade

Work through the approved plan in dependency order:

**Step 1 — Infrastructure** (hooks, settings, lib/)

- REPLACE files: Read from new framework, Write to project
- MERGE files: Read both versions, combine (new framework base + project-specific additions)
- For hooks: preserve project-specific safety rules (e.g., custom blocking patterns)
- For settings.json: keep project paths, adopt new hook structure
- For session-start.sh: keep project-specific tool checks, add new framework features

**Step 2 — Agents + Prompts + Commands**

- REPLACE: copy new versions (preserve project-only agents)
- ADD: create new files from framework

**Step 3 — Rules**

- MERGE: adopt new framework patterns + paths, preserve project-specific sections (e.g., custom security rules, project verification commands, technology-specific patterns)

**Step 4 — Skills**

- UPDATE: copy new SKILL.md + references/ from framework for each shared skill
- ADD: create new skill directories
- PRESERVE: leave project-specific skills untouched

**Step 5 — Documentation**

- UPDATE: TESTING_STRATEGY.md, MCP_INTEGRATION.md, CODING_STANDARDS.md (if changed)
- POPULATE: Any new `docs/context/` templates → write project-specific content
- ADD: new directories (docs/solutions/, docs/brainstorms/, scripts/pm/)
- UPDATE: llms.txt with current project stats

**Step 6 — Inventory & Config**

- Regenerate SKILLS_INVENTORY.md with all skills (updated + new + preserved)
- Update skills-registry.json
- Update CLAUDE.md: framework version, new skills in tables, new docs references

### Phase 3: Verify

1. Run the project's test command (from CLAUDE.md Commands): verify all tests pass
1. Run `/doctor` to validate framework health
1. Show summary:

```
## Framework Upgrade Complete: v{CURRENT} → v{NEW}

### Changes
- X files updated
- Y files added
- Z project-specific files preserved
- Tests: [PASS/FAIL]

### New Capabilities
- [list new skills added]
- [list new agents added]
- [list key improvements]
```

### Merge Strategy Reference

For detailed merge patterns (which sections to preserve, which to replace), consult `references/merge-strategy.md` — search for the relevant component type.

### Critical Operational Constraints

These constraints were discovered during real upgrades and MUST be followed:

#### 1. NEVER use Write/Edit tools for `.claude/` paths

Claude Code protects its own configuration directory. The Write and Edit tools **always prompt for user approval** when targeting files inside `.claude/`, even with `--dangerously-skip-permissions` enabled. This means every file write during the upgrade would require manual approval — defeating automation.

**Solution**: Use Bash tool with `cp` for file copies and shell commands for generated content:

```bash
# Copy from framework
cp "$NEW/.claude/skills/foo/SKILL.md" "$CUR/.claude/skills/foo/SKILL.md"

# Generate content
printf '%s\n' "line 1" "line 2" > .claude/rules/my-rule.md
```

#### 2. NEVER use `__PROJECT_ROOT__` in settings.json

The framework's `settings.json` template uses `__PROJECT_ROOT__` as a path placeholder. This placeholder may not be supported in all Claude Code versions. When unsupported, every hook command fails (file not found), which causes Claude Code to **prompt for permission on every tool call** — even with `--dangerously-skip-permissions`.

**Solution**: Use the runtime git-based path resolution pattern:

```json
"command": "cd \"$(git rev-parse --show-toplevel 2>/dev/null || echo .)\" && sh .claude/hooks/pre-tool-use.sh"
```

This resolves the project root reliably at runtime. When writing settings.json during upgrade, always use this pattern instead of `__PROJECT_ROOT__`.

#### 3. Safety hooks block their own content in Bash commands

The PreToolUse safety hook checks the **entire Bash command string** against blocked patterns. This means heredocs, printf statements, or Python code containing pattern text (e.g., the string "git push --force" in a message field) will trigger the safety block.

**Solution**: When writing files that contain safety pattern text (like `safety.patterns` itself), copy the base file with `cp` and append project-specific rules from a separate temp file:

```bash
# Copy base patterns from framework
cp "$NEW/.claude/hooks/rules/safety.patterns" .claude/hooks/rules/safety.patterns

# Append project-specific rules from a prepared file
cat project-safety-rules.txt >> .claude/hooks/rules/safety.patterns
```

Or use `base64` encoding to avoid the literal text appearing in the command.

#### 4. hooks.json changes can break the session

If Claude Code reads `.claude/hooks/hooks.json` alongside `settings.json`, replacing hooks.json mid-session can cause hook failures that cascade into permission prompts. During upgrade:

- Copy shell scripts FIRST (they sit inert until settings.json references them)
- Update settings.json to point to new scripts
- Update hooks.json LAST (or not at all — it's for plugin distribution, not project use)
