Rusty Update

/rusty-update

Consolidated Claude Code sync and parity tracking skill for RustyClawd.

What This Skill Does

This skill consolidates three previously separate tools into one unified workflow:

1. Feature Discovery - Fetches Claude Code's CHANGELOG.md and README.md from GitHub
2. Gap Analysis - Compares discovered features against .claude/data/feature_inventory.yaml
3. Reporting - Summarizes what's new, what's missing, and what's drifted
4. Issue Creation (optional) - Creates GitHub issues for gaps via the sync ledger

Additionally supports: 5. Deep Analysis - Deminifies installed Claude Code cli.js for pattern research

Modes

Quick Check (default)

Fetches Claude Code sources and compares against inventory. No side effects.

/rusty-update
/rusty-update check

Full Sync (creates GitHub issues)

Runs the Rust SyncMonitor which also creates GitHub issues for gaps.

/rusty-update sync

Requires: GITHUB_TOKEN environment variable.

Deep Analysis

Deminifies the installed Claude Code cli.js and creates searchable indices.

/rusty-update analyze

Requires: prettier and js-beautify (must be installed manually; skill will check and abort with instructions if missing).

Inventory Update

Interactively update the feature inventory after implementing new features.

/rusty-update inventory

Underlying Tools (Consolidated)

Data Files

• Docs Inventory (primary): docs/feature_inventory.yaml - Most comprehensive, with test evidence
• Sync Monitor Inventory: .claude/data/feature_inventory.yaml - Used by Rust sync monitor (may lag behind docs version)
• Sync Ledger: .claude/data/sync_ledger.json - Issue deduplication tracking

Important: The docs/ inventory is the more complete and up-to-date source. The .claude/data/ version is consumed by the Rust sync monitor. Both should be kept in sync.

Architecture

/rusty-update (skill)
    |
    +-- check: WebFetch CHANGELOG.md + README.md -> compare with inventory -> report
    |
    +-- sync:  cargo run claude_code_sync_cli -> full sync with issue creation
    |
    +-- analyze: scripts/analyze-claude-code.sh -> deminify + index cli.js
    |
    +-- inventory: Interactive inventory update workflow

Execution

When this skill activates, follow this procedure:

For check mode (default):

1. Fetch the official Claude Code CHANGELOG.md and README.md:

   • https://raw.githubusercontent.com/anthropics/claude-code/main/CHANGELOG.md
   • https://raw.githubusercontent.com/anthropics/claude-code/main/README.md

2. Read both local feature inventories:

   • docs/feature_inventory.yaml (primary, most comprehensive)
   • .claude/data/feature_inventory.yaml (sync monitor source)
   • Flag any drift between them

3. Compare features found in the changelog against the inventory:

   • New features not in inventory = Missing
   • Features marked partial = Incomplete
   • Features that may have changed = Drift

4. Report findings as a summary table with:

   • New Claude Code features since last check
   • Gaps (missing/incomplete/drift)
   • Recommended actions

For sync mode:

1. Verify GITHUB_TOKEN is set in environment. If not, abort with clear error.
2. Run the Rust sync monitor (pass token via environment, not CLI arg if possible):

   cargo run --package rustyclawd-tools --example claude_code_sync_cli -- \
     --inventory .claude/data/feature_inventory.yaml \
     --ledger .claude/data/sync_ledger.json \
     --token $GITHUB_TOKEN \
     --repo rysweet/RustyClawd
   

3. Report created issues

For analyze mode:

1. Check prerequisites: claude, prettier, js-beautify must be installed. Abort with install instructions if missing.
2. Run: echo "n" | bash scripts/analyze-claude-code.sh (pipe "n" to skip interactive VS Code prompt)
3. Report location of deminified files and indices

For inventory mode:

1. Read both inventory files: docs/feature_inventory.yaml (primary) and .claude/data/feature_inventory.yaml
2. Flag any drift between them
3. Ask what features to add/update
4. Write updated inventory to BOTH files to keep them in sync
