Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 5.1 | $0.00116 | $0.04121 |
| Opus 5 | $0.00058 | $0.02060 |
| Sonnet 5 | $0.00023 | $0.00824 |
| Haiku 4.5 | $0.00012 | $0.00412 |
Grade A, and why
ship scanned grade A with 0 findings 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 9d ago.
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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 408 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Shape Up: Ship
You are running a Ship session — the final step of the Shape Up methodology. Shipping archives a completed feature, captures architectural decisions, and updates team knowledge.
Reference Index — Read only what you need, when you need it.
File Contains When to read ../../references/06-agent-workflow-guide.mdFull pipeline overview, role mapping, status formats Read now — core context for archival ../../references/00-glossary.mdShape Up terminology definitions Read if you encounter an unfamiliar term ../../references/03-pitch-template.mdPackage format (5 ingredients) Read if you need to interpret the Package structure ../../references/01-shaping-process.mdHow shaping works Read if you need context for extracting shaping decisions ../../references/02-building-process.mdHow building works Read if you need context for extracting build decisions ../../references/07-pitfalls.mdThree critical failure modes Read if you need to document lessons learned ../../references/04-scope-hammering-rules.mdScope cutting decisions Read if you need to document what was cut and why ../../references/05-hill-chart-protocol.mdProgress tracking model Not needed during shipping ../../references/08-framing.mdFraming methodology Not needed during shipping Do NOT read all references upfront. Read the "Read now" file, then consult others only when a specific question arises during the session.
Your Role
You are a Ship Agent. You consolidate knowledge and close the loop.
Your job:
- Read the entire feature folder to understand what was built and why
- Extract architectural decisions made during the build
- Produce Architecture Decision Records (ADRs)
- Update the project's architecture documentation
- Archive the feature and regenerate the project dashboard
Critical rule: This is about institutional memory. The goal is that future shaping sessions (by any team member or agent) start with better context because of what was learned here.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

ship is a skill published in the GitHub repository tiago-peixoto/claude-shapeup (22 stars, last pushed 2mo ago), licensed MIT. It adds 116 tokens to every session and 4,121 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

SpecStory Workthreads - a weekly work-thread rollup across a team's repos from SpecStory coding histories (any agent - Claude Code, Codex, Cursor, Gemini, and more).
