QUICK START

How to use this skill

Bring this guide into your coding agent with a prompt tailored to the tool you use.

Open your project in Codex.
Copy and paste the prompt below.
Review files and risks before approving any action.

Prompt to paste

Inspect the Agent Skill at https://github.com/oliver-kriska/claude-elixir-phoenix/blob/HEAD/.claude/skills/cc-changelog/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/cc-changelog, but wait for my approval before writing files or running scripts.

Copying this prompt does not install or run the skill. Review third-party files before use.

Claude Code Changelog Assistant

Tracks Claude Code releases against the plugin. Fetches the CC changelog, extracts entries newer than last check, and analyzes impact on plugin components (agents, skills, hooks, config).

Usage

/cc-changelog                  # Check for new CC versions, analyze impact
/cc-changelog --full           # Re-analyze all versions (ignore last check)
/cc-changelog --set=2.1.85     # Reset last checked version (then re-run)

Execution Flow

Step 1: Fetch & Extract New Entries

bash "${CLAUDE_PROJECT_DIR}/scripts/fetch-cc-changelog.sh"

If output starts with STATUS: UP_TO_DATE → report "No new CC versions" and stop.

If STATUS: NEW_VERSIONS → continue with the changelog content below the header.

For --full: run bash "${CLAUDE_PROJECT_DIR}/scripts/fetch-cc-changelog.sh" --all For --set=X: run bash "${CLAUDE_PROJECT_DIR}/scripts/fetch-cc-changelog.sh" --set=X, then re-run without flag.

Step 2: Analyze Impact

Read the new changelog entries. For EACH entry, classify into one of:

Category	Meaning	Action
BREAKING	May break existing plugin functionality	Immediate fix required
OPPORTUNITY	New CC feature the plugin could use	Add to backlog/plan
RELEVANT FIX	CC fixed a bug we worked around	Check if workaround can be removed
DEPRECATION	CC removing something we use	Plan migration
INFO	Good to know, no action needed	Log in memory update

Cross-reference against plugin components using rules in ${CLAUDE_SKILL_DIR}/references/analysis-rules.md.

Step 3: Generate Report

Output a structured report:

## CC Changelog Analysis: v{last_checked} → v{latest}

### BREAKING (action required)
- [version] description → **Impact**: which plugin file/component
  **Fix**: specific action needed

### OPPORTUNITY (new features)
- [version] description → **Use case**: how plugin could benefit
  **Files**: which plugin files to update

### RELEVANT FIX (workaround removal)
- [version] description → **Current workaround**: what we do now
  **Action**: can we simplify?

### DEPRECATION (migration needed)
- [version] description → **We use this in**: file:line
  **Migration**: what to change

### INFO (no action)
- [version] brief summary (collapsed)

Step 4: Update State

After user reviews the report, ask:

"Update last checked version to {latest}? This also updates the CC internals memory file. [Yes/No]"

If yes:

Run bash "${CLAUDE_PROJECT_DIR}/scripts/fetch-cc-changelog.sh" --set={latest}
Update memory file reference_cc_source_internals.md with new findings
If BREAKING or DEPRECATION items found, offer to create a plan

Iron Laws

ALWAYS fetch before analyzing — never analyze stale cache
NEVER auto-update state — user must confirm after reviewing report
ALWAYS cross-reference plugin files — don't just summarize, map to impact
BREAKING changes are BLOCKERS — surface first, prominently
Track the audit version — state file is the source of truth
