first-officer

first-officer is a skill for Claude Code, Codex from iamcxa/kc-claude-plugins. It costs 68 tokens per session (517 once invoked), scanned A, original, MIT.

A step-by-step workflow for delivering a batch of work from dispatch through review, user acceptance testing, and closure. It uses scripts to check evidence and move the batch between stages.

In plain words
What is it for?
Use it to run the documented batch process, accept worker evidence, open and resolve reviews, run end-to-end checks, hand work to user testing, and close the batch.
Why use it?
It prevents work from being shipped before the required review and checks are complete. User acceptance testing means confirming that the result works for its intended users.

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

first-officer 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 2d 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.

What it actually says

kc-ship-flow first officer

docs/ship/README.md's ## Local Profile table is this skill's declared input before resolving or dispatching a batch, not the full README as a policy bundle. local-profile-check.py below verifies the table's required rows; nothing checks what else this skill reads.

Refuse before dispatch

Run:

python3 kc-ship-flow/scripts/local-profile-check.py docs/ship/README.md

A non-zero exit names the missing row on stderr. Do not dispatch a batch while this refuses — most commonly the Runtime row, which selects local subagent or Conductor cloud dispatch for the stage that follows.

Run the station chain

Advance one commissioned docs/ship batch entity through its six stages in order, calling each stage's installed script from docs/ship/README.md's per-stage lines:

  1. dispatchedkc-ship-flow/scripts/fenced-dispatch.sh
  2. acceptedkc-ship-flow/scripts/accept-evidence.sh
  3. reviewedkc-ship-flow/scripts/open-pr.sh, then kc-ship-flow/scripts/disposition.py
  4. uat (gate) — kc-ship-flow/scripts/e2e-gate.py, kc-ship-flow/scripts/uat-doc.py, kc-ship-flow/scripts/notify.sh
  5. merged — no kc-ship-flow script; observe the GitHub merge through Spacedock's pr-merge mod
  6. closedkc-ship-flow/scripts/dev-debrief.py, then kc-ship-flow/scripts/ship-debrief.py

Write and check each stage's pin with kc-ship-flow/scripts/pin.py write --station <name> / check --station <name> before advancing past it. Validate the closed stage's close receipt with docs/plan-flow/schema/validate-receipt.py <plan-receipt.json> <approval.json> <close-receipt.json> before terminalizing the entity.

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.
