Moved to phuryn/product-engineering, where it is maintained in the ai-shipping plugin; this copy says where it went and how to install it. Use when asked to review changes, find bugs, audit a codebase, or check whether a fix is safe.

Moved to phuryn/product-engineering, where it is maintained in the ai-shipping plugin; this copy says where it went and how to install it. Use when asked to find where the code does something other than its docs say.

Moved to phuryn/product-engineering, where it is maintained in the ai-shipping plugin; this copy says where it went and how to install it. Use when asked to document an AI-built app so it can be reviewed before it ships.

Create a lean, decision-ready Product Requirements Document with an 8-section template: summary, contacts, background, objective, market segments, value propositions (6-part JTBD template), solution, and release. Lean by default (about one to two pages), with…

Red-team a PRD, roadmap, or strategy by attacking its load-bearing assumptions before reality does. Steelmans then attacks each claim, ranks failure modes by impact × likelihood × cheapness-to-test, and returns the cheapest test and kill criteria for each.…

Analyze A/B test results with statistical significance, sample size validation, confidence intervals, and ship/extend/stop recommendations. Use when evaluating experiment results, checking if a test reached significance, interpreting split test data, or…

Perform cohort analysis on user engagement data — retention curves, feature adoption trends, and segment-level insights. Use when analyzing user retention by cohort, studying feature adoption over time, investigating churn patterns, or identifying engagement…

Generate SQL queries from natural language descriptions. Supports BigQuery, PostgreSQL, MySQL, and other dialects. Reads database schemas from uploaded diagrams or documentation. Use when writing SQL, building data reports, exploring databases, or translating…

'Ask Claude', 'have Claude build or review this': drive Claude Code headless (claude -p) from another agent as a peer, builder or fresh reviewer.

Before 'ship it', a deploy or release, for 'an independent review', and after each fix until a round is clean: a fresh reviewer that never saw the build.

Is this safe to ship? Documents the app, wires the agent's context, runs the correctness, security and performance reviews and an independent unsteered pass, maps test coverage, and compiles one reviewer-ready shipping packet. Started by name only:…

Planning a SaaS stage, 'what's next', 'where are we', calling a stage done: the detailed path from an idea to production, each stage with its done-when.

Adding analytics, session recordings, heatmaps, 'what did users do', Clarity or PostHog: behaviour analytics without analytics cookies, read back by the agent, and what changes when a cookie comes in.

Before 'push it', 'ship it', a deploy, release or go-live, or calling a stage done: the gate, the owner's preview, go/no-go, promote, prove it serves, roll back.

A Supabase query, RPC or migration, 'db push', 'supabase link', RLS or grants, a Supabase error: server-only keys, deny-all RLS, migrations via the CLI.

Adding a variable or secret, 'set up production', a domain or a provider token, 'which database is this', a leaked key: dev and production for an AI-built app, backups, incidents.

Deploy, run, list, or tear down the agents in this repo's .managed-agents/ folder on Anthropic Managed Agents. Use when the user says "deploy my agents", "ship this agent to the cloud", "run the deployed agent", or asks about managed-agent deployment.

Use whenever you state a fact. End the answer with a short Sources list mapping each claim to a file, URL, or reasoning. Shared across agents.

Edit AI-sounding text so it reads like a careful person wrote it, without changing what it says. Two modes. Rewrite: edit the text you are given (posts, emails, docs, release notes, replies, landing pages). Interview: when a draft is AI-composed and thin, ask…

Use OpenAI Codex CLI as a peer collaboration partner — same standing as Claude, not a one-shot tool. Bring Codex in EARLY (ideation, framing decisions, stuck moments), not only for late peer-review. Hand it strategic context (target, research, draft,…

DON'T USE THAT SKILL. IT'S JUST AN EXAMPLE. Summarize today's Gmail inbox by category with anonymized senders and subjects, then surface the top 3 emails to focus on next. Run only when the user types /email-summary.

Scan Gmail (default: today's inbox), produce an anonymized summary with action points, then export each email to Linear as an issue with a sensible priority. No personal details — names, email addresses, or company identifiers — ever leave the summary or…

Spawn a new Claude Code session with remote control enabled (default: a detached background session — via screen on macOS/Linux, via a minimized PowerShell Start-Process on Windows — fully remote-safe, no approvals/windows), so it appears in the mobile Claude…

Initialize a PM Brain — a markdown-native second brain for a product operator (PM, product lead, founder, or anyone accountable for one product or initiative) doing judgment-heavy work with scattered inputs. Detects greenfield vs. migration mode, runs a…

Review a Python solution against a markdown spec, run it, and report bugs.

Embed Claude agents in a web app with the Claude Agent SDK. One server-side wrapper runs any agent kept as a directory under .claude/agents/<name>/ (its AGENTS.md, knowledge files, skills and MCP servers), isolated from the repo and the machine, streamed to a…
