launch-review

launch-review is a skill for Claude Code from justnau1020/claude-os. It costs 31 tokens per session (1,367 once invoked), scanned A, original, Apache-2.0.

A guided review process for deciding whether a software feature is ready to launch. It uses several separate reviewers to debate risks, create a checked action plan, and apply fixes.

In plain words
What is it for?
Use it to review a checkout flow, API release, or other feature against its scope and constraints. It helps identify fixes and carry them through to implementation.
Why use it?
It helps uncover missed risks and unclear decisions before release, then turns the findings into agreed work. It also keeps each review stage focused.

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

launch-review 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 11d 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.

Launch Review Pipeline

A structured, multi-phase agent pipeline that evaluates feature readiness through adversarial debate, creates a reviewed action plan, and executes fixes. Each phase runs as an isolated team to prevent context bloat.

Invocation

/launch-review [topic] [--scope "focus areas"] [--constraints "known constraints"]

Examples:

  • /launch-review "checkout experience" --scope "cart, payment, confirmation"
  • /launch-review "v2 API launch" --constraints "backwards compatible, feature flag gated"

Phase 0: Constraints Gathering (No Team)

Before spawning any agents, the main agent MUST:

  1. Ask the user for known constraints:
    • Legal restrictions (prohibited libraries, data sources, licenses)
    • Business rules (budget limits, timeline, must-have vs nice-to-have)
    • Scope boundaries (what's in/out of this review)
    • Any prior decisions already made
  2. Check memory for relevant project constraints
  3. Compile a constraints block that gets injected into every agent's prompt

Format:

CONSTRAINTS (non-negotiable):
- [constraint 1]
- [constraint 2]
DO NOT propose solutions that violate these constraints.

This phase prevents the #1 failure mode: agents recommending something that's already been ruled out.

Phase 1: Debate Team

Create team: TeamCreate with name {topic}-debate

Agents (5):

Agent Role Type
arch-critic Code auditor -- finds gaps, bugs, half-baked features general-purpose
comp-critic Competitive benchmarker -- researches competitors, holds us to that bar general-purpose
code-defender Argues launch readiness from actual code evidence general-purpose
industry-defender Argues competitive positioning from market research general-purpose
moderator Synthesizes all 4 reports, writes verdict general-purpose

Flow:

  1. Spawn all 5 agents. The 4 debaters run in parallel. Moderator is blocked by all 4.
  2. Each debater sends their report to moderator via SendMessage.
  3. Moderator writes the report to docs/{TOPIC}_READINESS_REPORT.md.
  4. Moderator sends summary to team-lead.

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.
