prelaunch

prelaunch is a skill for Claude Code, Codex from VoxTechnologies/transmute-framework. It costs 83 tokens per session (3,302 once invoked), scanned A, original, MIT.

A pre-launch verification workflow that checks whether a complete product is ready for production deployment, meaning release to real users.

In plain words
What is it for?
Use it to run final launch checks, validate deployment readiness, and produce a launch checklist.
Why use it?
It catches unresolved problems in areas such as security, accessibility, performance, documentation, implementation completeness, and production configuration before launch.

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

prelaunch 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.

Stage 6H: Final Check Before Production Deployment

Read the detailed guide at ${CLAUDE_SKILL_ROOT}/references/prelaunch-detailed-guide.md for the complete verification procedures, checklist templates, and report format.

Lead a multi-agent pre-launch verification project. Perform a comprehensive final check of the COMPLETE product before it goes live. This is the last gate between development and real users.

Stage Sequence (recommended ordering): Stage 5B → 6A/6B/6C (parallel) → 6E → 6F → 6G → 6D (Documentation) → 6H (this stage) → 6V (Verification) → [6R] → 6P or 6P-R → 7 (Deploy) → 7V → 7D

Prerequisites

Verify before starting — this stage has the strictest prerequisite checks:

  1. ./plancasting/_audits/implementation-completeness/report.md exists with PASS or CONDITIONAL PASS. If missing, STOP — 5B is a prerequisite gate. CONDITIONAL PASS requires each Category C issue to have a documented workaround. FAIL means STOP.
  2. ALL Stage 6 audit reports exist:
    • ./plancasting/_audits/security/report.md (6A)
    • ./plancasting/_audits/accessibility/report.md (6B)
    • ./plancasting/_audits/performance/report.md (6C)
    • ./plancasting/_audits/documentation/report.md and ./docs/ (6D) — mandatory for software products; skip only if plancasting/tech-stack.md indicates non-software product or documentation explicitly marked N/A
    • ./plancasting/_audits/refactoring/report.md (6E)
    • ./seed/README.md and ./plancasting/_audits/seed-data/report.md (6F) — skip if plancasting/tech-stack.md indicates N/A
    • ./plancasting/_audits/resilience/report.md (6G) For any missing report (except 6D/6F if skipped), STOP — prerequisite not completed. For each existing report, read its ## Gate Decision heading and verify the gate passed. If any shows FAIL, STOP. If CONDITIONAL PASS, verify the conditions are acceptable for launch.
  3. Check for unfixable violation files from prior stages (not all stages produce these): ./plancasting/_audits/security/unfixable-violations.md, ./plancasting/_audits/accessibility/unfixable-violations.md, ./plancasting/_audits/performance/unfixable-violations.md, ./plancasting/_audits/refactoring/unfixable-violations.md, ./plancasting/_audits/resilience/unfixable-violations.md, ./plancasting/_audits/documentation/unfixable-violations.md, ./plancasting/_audits/seed-data/unfixable-violations.md. If any exist, read them and treat CRITICAL items as launch blockers. If a file does not exist, that stage had no unfixable violations — skip it.
  4. Read ./CLAUDE.md and ./plancasting/tech-stack.md for project conventions.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

prelaunch is a skill published in the GitHub repository VoxTechnologies/transmute-framework (4 stars, last pushed 1mo ago), licensed MIT. It adds 83 tokens to every session and 3,302 once invoked, about $0.0004 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.
