iterate-post-launch

iterate-post-launch is a skill for Claude Code, Codex from kensaurus/cursor-kenji. It costs 69 tokens per session (2,237 once invoked), scanned A, original, MIT.

A post-launch workflow for reading production errors, logs, and the live app, then choosing and applying the next fixes.

In plain words
What is it for?
It helps triage issues, rank a small improvement plan, fix bugs or polish problems, and check the live result.
Why use it?
It replaces guesswork about what to improve with evidence from real users and verifies that fixes work in production.

    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

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

iterate-post-launch 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 5d 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.

iterate-post-launch — Production Signal → Prioritised Fix Loop

Degree of freedom: MIXED. Triage and sprint plan [HIGH freedom]; signal pulls, confirmation-before-edit, and live verify [LOW freedom — run exactly].

You shipped. That is the beginning, not the end. Real users hit real paths you did not test. Sentry, Supabase logs, and the live UI tell you exactly what to fix next — if you know how to read them. This skill turns those signals into a ranked, actionable improvement plan and then implements it.

Plan → Signal → Triage → Fix → Verify. Do not guess what to improve. Let production data point to the highest-impact work first.

Before ANY browser action, read protocol-browser-anti-stall.

How to reason

  1. Observe — Sentry, Supabase logs/advisors, and a headed walkthrough in parallel
  2. Interpret — impact × effort from those signals, not a guessed redesign
  3. Classify — Critical / High / Medium / Low; present the sprint before editing
  4. Verify — live Playwright (or the failing query) before resolving the Sentry issue

Worked example

Observe: Sentry TypeError on /checkout 2.4k events / 14d; advisor missing index on orders(user_id); live empty cart has no message. Interpret: checkout crash blocks paying users — outranks the index and the empty state. Classify: Critical = crash fix; High = index; Medium = empty-cart copy. Present that sprint; do not start a homepage rewrite. Verify: headed -s=post-launch replay of checkout → 2xx; then sentry:update_issue resolved.

Self-critique before reporting

  • Signal-backed — every fix traces to Sentry, logs, advisors, or the walkthrough
  • Live before resolve — Playwright or the query, then Sentry resolved
  • Rows ask first — asked-for schema ships; DELETE/UPDATE on real rows waits
  • Right owner — one named bug → workflow-fix-and-ship

Phase 0: Context [LOW freedom — run exactly]
