verifying-wave-completion

verifying-wave-completion is a skill for Claude Code, Codex from Acendas/shipyard. It costs 14 tokens per session (2,155 once invoked), scanned A, original, MIT.

A completion check for a wave, meaning a verified group of related sprint tasks. It checks several conditions together, including the build, tests, code changes, merged work, and completion records.

In plain words
What is it for?
Use it at the end of each implementation wave before advancing the sprint to confirm that all required verification conditions hold.
Why use it?
A single passing test can miss a dropped commit, flaky behavior, or unfinished work. This check reduces the chance of moving to the next wave too early.

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

verifying-wave-completion 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 4d 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 — 132 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Verifying Wave Completion

Render before asking. Before any AskUserQuestion, render the decision context as assistant chat text. Content that exists only in a Read result, a subagent/Agent return, or the question/option strings does not count as rendered (the UI shows a compact card) — restate it in chat first.

A passing wave-scoped probe is necessary but not sufficient. The wave is fully complete only when six invariants hold simultaneously. This capability skill runs that composite check after the existing wave-boundary steps (rebase + ff-merge, wave-scoped build, REFACTOR + MUTATE, wave-scoped tests, wave VERIFY) and gates advance-to-next-wave on the result.

The check exists because the structured return contract makes false completion structurally hard at the subagent boundary, but the wave boundary is one level up — and pre-this-skill, the only gate there was a single probe pass. A flaky test, a dropped commit, or a subagent that exited mid-flight without writing its completion event could all slip through.

When to Invoke

/ship-execute Step 4 calls this skill as the final gate before advancing the wave counter, AFTER the existing in-line checks have all reported green. Job: confirm the composite picture matches the per-step verdicts.

Other entry points:

  • /ship-review Stage 1 (sprint-level) may invoke this as a per-wave audit when re-running review on an archived sprint.
  • Manual invocation when a user wants to confirm a specific wave is truly complete before advancing.

Inputs

  • wave_number — e.g., 2
  • task_ids — list of task IDs dispatched in this wave, e.g., ["T-042", "T-043", "T-044"]
  • data_dir — literal <SHIPYARD_DATA> path
  • working_branch — git branch
  • wave_base_sha — working-branch HEAD BEFORE the wave started (set by /ship-execute at wave entry)
  • wave_head_sha — working-branch HEAD AFTER the wave's merges (set after the rebase + ff-merge step)
  • wave_probe_capture — path to the wave-scoped test capture file
  • wave_probe_exit_code — exit code from the wave-scoped test run
  • wakeup_budget — number of recovery wakeups before escalation. Default 3.
  • wakeup_delay_seconds — delay per wakeup. Default 180 (warm-cache window — see schedule-wakeup-discipline.md).

Changes

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.
