Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

ship-feature 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 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.

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 — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ship-feature

Follow the canonical workflow in ~/.config/ship-feature/WORKFLOW.md (installed by this project). It is the single source of truth — do not restate or fork it here. Read it before your first change in a session.

Pick the lane first

The careful lane is only for: payments and subscriptions; ad consent and ad-revenue paths; authentication and account deletion; database migrations and data deletion; security fixes; store-policy changes (permissions, SDKs that collect data); and any change the human puts there.

Everything else is the light lane. Say which lane you picked, and why, in one line.

The light lane (default)

  1. Work in a git worktree off the default branch (never the main tree). Stage explicit paths.
  2. Implement, with tests at the level you touched. Commit.
  3. Review once, with the configured panel, on the branch diff: ship-feature review --author <self> --base origin/<default>. No --reviewers: the panel is REVIEWERS in ~/.config/pr-review-relay/config, and its seats run in parallel. Name the seats that ran: a seat whose CLI is not installed is skipped and the round still exits 0; a seat that fails (timeout, quota, no usable review), or a round where no seat ran, exits 3. If the same seat fails twice, run the other seats with --reviewers and say which seat you dropped.
  4. Fix only what breaks the change for a real user, loses money, or leaks data. Record the other findings in the merge message (-m "Not fixed: …"). No second round, unless the fix was large.
  5. ship-feature land [-m <message>]... from inside the worktree. The pre-push hook runs on the exact merged tree. If it refuses, nothing landed: fix what it reported, or run land again.
  6. Ship it if the change needs a release or a deploy. Done means live: report the version or the deployed commit, not "merged".

No plan, no plan review, no PR, no human merge gate.

The careful lane

  1. Write a short plan in ~/.config/ship-feature/plans/<repo>-<slug>.md (mkdir -p it if missing; never the repo, never /tmp, which a reboot can wipe).
  2. ship-feature plan-review <that file> — one round, no --reviewers (the config is the panel). Read the startup lines and say which reviewers actually ran: a benched seat is dropped and the run still exits 0. Fix the blockers in the plan.
  3. 🚦 Stop for the human to approve the plan.
  4. ship-feature preflight, implement in a worktree, open a PR.
  5. ship-feature relay --author <self> --context-file <plan> --max-rounds 2 — two rounds at most: round 1 the full panel; round 2, only if round 1 raised a qualifying finding, the full panel on the SHA that will merge. Post dispositions before round 2. Whatever is still open after round 2 goes to the merge gate as an open item, not into a round 3.
  6. 🚦 Stop for the human to merge. Never self-merge in this lane.
  7. Verify the tests on the merge commit.

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.
