Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00031 | $0.06279 |
| Opus 5 | $0.00015 | $0.03139 |
| Sonnet 5 | $0.00006 | $0.01256 |
| Haiku 4.5 | $0.00003 | $0.00628 |
Grade A, and why
shipkit-update scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 725 lines — stays where its author put it; the contents beside it link to each section on GitHub.
shipkit-update - Install & Update Shipkit
Purpose: One skill to install Shipkit fresh or update an existing installation. Archives previous versions safely and intelligently merges user content.
Role: Bootstrap/update skill. Can be fetched directly from GitHub even before Shipkit is installed.
Why This Skill Exists
Updates are tricky without version tracking and safe migration.
This skill provides:
- Detection - Finds all Shipkit variants (current + legacy naming)
- Safe archiving - Never deletes, always preserves
- Clean install - Fresh framework files from source
- Intelligent merge - Claude merges user content into new structure
When to Invoke
User-invoked:
- "Install Shipkit" / "Update Shipkit" / "Upgrade Shipkit"
/shipkit-update(explicit)- "Reinstall Shipkit from GitHub"
Bootstrap scenario:
- User pastes GitHub link + "install this"
- Claude fetches this skill directly and executes
Prerequisites
For installation:
- Access to GitHub (WebFetch or gh CLI)
- Write access to project root
For update:
- Existing Shipkit installation (any version)
Process
Completion Tracking (MANDATORY)
After getting user permission (Step 0), create tasks for every remaining step:
TaskCreate: "Detect existing installation"TaskCreate: "Archive existing installation + write MANIFEST.md"TaskCreate: "Run npx installer"TaskCreate: "Merge CLAUDE.md (+ subfolder CLAUDE.md files)"TaskCreate: "Merge settings.json"TaskCreate: "Scan settings.local.json for stale refs"TaskCreate: "Migrate user content from archive"TaskCreate: "Cleanup deprecated .md files"TaskCreate: "Output comprehensive summary"
Rules:
TaskUpdateeach task tocompletedonly after the step is fully done- The installer completing (Step 3) is NOT the finish line — 5 more steps remain
- Do NOT present the final summary until ALL tasks show completed
- The CLAUDE.md merge task includes subfolder CLAUDE.md files, not just root
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
