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 | $0.01117 | $0.01117 |
| Opus 5.5 | $0.00447 | $0.00447 |
| Sonnet 5.5 | $0.00223 | $0.00223 |
| Haiku 4.5 | $0.00112 | $0.00112 |
Grade A, and why
ship AGENTS.md 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 1mo 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.

Architecture
Ship has one opt-in workflow layer. It fires only during user-triggered Ship
workflows, especially /ship:auto:
session-start.shinjects only a small/ship:use-shiprouting hint; no docs index or artifact content./ship:use-shipchooses the smallest useful standalone skill, phase bundle, or full workflow.- Full workflow runs write raw input to
.ship/tasks/<task_id>/input/requirement.md. - The runner owns exactly one state surface: the frontmatter of
.ship/ship-auto.local.md. There is no side-state; agents may create task-specific notes under the task dir if useful. - Markdown artifacts and repository code are the output plane.
- Bulk artifacts move between agents as file paths, never pasted prompt text: story briefs, implementer reports, and review packages live in the self-ignoring
.ship/scratch/. - Durable production artifacts may be organized under
docs/ship/<task-id-or-req-id>/when the repo lacks an existing convention. stop-gate.sh— blocks session exit while.ship/ship-auto.local.mdis active (with fast-path for terminal phases)auto-orchestrate.sh— code-driven state machine for staged workflows (init, resume, complete, status commands)phase-guardrail.sh— PreToolUse hook enforcing artifact access rules per phase (QA independence, review read-only, state file protection)- Claude Code loads hooks through plugin
hooks/hooks.json(${CLAUDE_PLUGIN_ROOT}). Codex loadshooks/codex-hooks.json(${PLUGIN_ROOT}) via the explicit"hooks"pointer in.codex-plugin/plugin.json— the pointer is REQUIRED: without it Codex falls back tohooks/hooks.json, whose variable does not expand there.

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.
