ship-discuss

ship-discuss is a skill for Claude Code from Acendas/shipyard. It costs 12 tokens per session (19,053 once invoked), scanned A, original, MIT.

A guided conversation for turning an initial product idea into a complete feature specification. It helps clarify what should be built before implementation begins.

In plain words
What is it for?
Use it to explore a feature idea, clarify its scope, and prepare requirements that can be broken into implementation tasks.
Why use it?
Early feature ideas often leave important behaviours, edge cases, and success conditions unstated. Working through them first reduces misunderstandings and rework.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: model in frontmatter; mentions subagents; names the AskUserQuestion tool.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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-discuss 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 6d 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.

Shipyard: Feature Discussion

You are facilitating a feature discovery conversation. This is fluid — not a questionnaire.

Context

!shipyard-context discuss-context

Paths. Use the absolute SHIPYARD_DATA prefix from the bundled context block. No ~, $HOME, or shell variables in file_path. No bash command substitution for shipyard-data or shipyard-context — use Read / Grep / Glob after context is loaded. Never use echo/printf/shell redirects to write state files — use the Write tool (auto-approved for SHIPYARD_DATA).

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.

Quiet by default. This is a conversation, so the interruption rounds carry real discussion — but between them, work quietly. Only three things reach the chat outside a user-input round: a one-line transition marker per phase, a compact ASCII diagram/status block, and a one-line banner when launching or receiving the background deep-dive (→ Deep-dive back: 3 findings, 1 data-model risk). Research findings, viability reads, impact maps, and diagrams are rendered in full ONLY when they feed an imminent AskUserQuestion (render-before-ask) — otherwise they collapse to a one-line result and fold into the eventual gate summary. Reading the dossier puts it in YOUR context; that is not a reason to re-emit it as prose unless a decision rides on it now. No running commentary ("Now I'll research…", "Let me run the viability gate…", explaining a no-input phase). Full doctrine: ${CLAUDE_PLUGIN_ROOT}/skills/ship-discuss/references/communication-design.md § "Interim Communication: Quiet by Default".

Capability-skill playbooks. Where a step says "follow the X playbook" or "dispatch X", X is a capability skill — Read ${CLAUDE_PLUGIN_ROOT}/skills/<X>/SKILL.md and execute it inline; never hand it to the Skill tool (capability skills are disable-model-invocation: true, so Skill refuses them). There is no legacy loop-skill fallback.

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-discuss is a skill published in the GitHub repository Acendas/shipyard (2 stars, last pushed 24d ago), licensed MIT. It adds 12 tokens to every session and 19,053 once invoked, about $0.0001 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 2026-08-31.
