ship-backlog

ship-backlog is a skill for Claude Code, Codex from Acendas/shipyard. It costs 12 tokens per session (4,772 once invoked), scanned A, original, MIT.

A tool for viewing and organising a Shipyard project backlog. A backlog is a prioritised list of planned work.

In plain words
What is it for?
Use it to view backlog items, groom the list, and manage feature priorities and statuses in Shipyard.
Why use it?
It keeps feature details and priorities in one place and helps teams decide which work should come first.

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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-backlog 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 3d 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 — 277 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Shipyard: Backlog Manager

Manage the prioritized backlog. Default sort is by RICE score (Reach x Impact x Confidence / Effort — higher means more valuable).

Data model: BACKLOG.md is an ordered index of feature IDs. All feature data (title, RICE, points, status, complexity) is read from feature files on display. Never duplicate feature data into BACKLOG.md. See ${CLAUDE_PLUGIN_ROOT}/project-files/rules/shipyard-data-model.md (rules live in the plugin in 2.0).

Context

!shipyard-context backlog-context

Paths. All file ops use the absolute SHIPYARD_DATA prefix from the context block. No ~, $HOME, or shell variables in file_path. Bash is for shipyard-context (reads) and shipyard-data feature|backlog|idea ... (state mutations) ONLY — no other shell. Never use echo/printf/shell redirects to write state files — use the Write tool (auto-approved for SHIPYARD_DATA). Never hand-Edit feature-file frontmatter or BACKLOG.md IDs/last_groomed — those are CLI-owned (feature set, feature set-status, backlog add|remove|rank|set). Feature/epic bodies and the BACKLOG.md Overrides section remain Edit-tool surface.

Onboarding gate. If the bundled context contains SHIPYARD_ONBOARDING_REQUIRED=true, run the exact SHIPYARD_ONBOARDING_COMMAND once with Bash, report the CLI output to the user, and STOP. Do not infer setup state by reading or writing Shipyard state files; onboarding decisions are CLI-owned.

Execution rules (load-bearing):

  • Do every read yourself with Read/Grep/Glob. NEVER dispatch a subagent (Agent/Explore/Task) to gather board data. Data gathered in a subagent never lands in this context, and the board cannot be rendered from data you do not hold. (Incident 2026-07-21: a delegated gather produced a blind AskUserQuestion with no board rendered.)
  • Render before asking. Render the full board as text output BEFORE the first AskUserQuestion. The ask at the end of the board is the ONLY entry into the interactive loop; an AskUserQuestion with no board above it is always a bug. Board data existing only in a Read result, a subagent return, or the question/option strings does not count as rendered (the UI shows a compact card) — only assistant chat text above the ask does.
  • Quiet by default. The board and the drill-down/grooming summaries ARE the render-before-ask content — render those in full. But between them, work quietly: read feature files, stage grooming decisions, and run shipyard-data mutations without narrating each read or each staged change. Surface a one-line result after a batch of mutations (→ Applied: 3 reprioritized, 1 archived), not a play-by-play. No running commentary ("Now I'll read F004…", "Let me check the next one…"). Full doctrine: ${CLAUDE_PLUGIN_ROOT}/skills/ship-discuss/references/communication-design.md § "Interim Communication: Quiet by Default".

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.
