From a35b5b3c6d4ae3df7009058f1069f4f65720128f Mon Sep 17 00:00:00 2001 From: Garry Tan Date: Tue, 17 Mar 2026 23:01:10 -0700 Subject: [PATCH] feat: add /canary, /benchmark, /land-and-deploy skills (v0.7.0) Three new skills that close the deploy loop: - /canary: standalone post-deploy monitoring with browse daemon - /benchmark: performance regression detection with Web Vitals - /land-and-deploy: merge PR, wait for deploy, canary verify production Incorporates patterns from community PR #151.

Always run `touch` to mark as seen. This only happens once. + +## AskUserQuestion Format + +**ALWAYS follow this structure for every AskUserQuestion call:** +1. **Re-ground:** State the project, the current branch (use the `_BRANCH` value printed by the preamble — NOT any branch from conversation history or gitStatus), and the current plan/task. (1-2 sentences) +2. **Simplify:** Explain the problem in plain English a smart 16-year-old could follow. No raw function names, no internal jargon, no implementation details. Use concrete examples and analogies. Say what it DOES, not what it's called. +3. **Recommend:** `RECOMMENDATION: Choose [X] because [one-line reason]` — always prefer the complete option over shortcuts (see Completeness Principle). Include `Completeness: X/10` for each option. Calibration: 10 = complete implementation (all edge cases, full coverage), 7 = covers happy path but skips some edges, 3 = shortcut that defers significant work. If both options are 8+, pick the higher; if one is ≤5, flag it. +4. **Options:** Lettered options: `A) ... B) ... C) ...` — when an option involves effort, show both scales: `(human: ~X / CC: ~Y)` + +Assume the user hasn't looked at this window in 20 minutes and doesn't have the code open. If you'd need to read the source to understand your own explanation, it's too complex. + +Per-skill instructions may add additional formatting rules on top of this baseline. + +## Completeness Principle — Boil the Lake + +AI-assisted coding makes the marginal cost of completeness near-zero. When you present options: + +- If Option A is the complete implementation (full parity, all edge cases, 100% coverage) and Option B is a shortcut that saves modest effort — **always recommend A**. The delta between 80 lines and 150 lines is meaningless with CC+gstack. "Good enough" is the wrong instinct when "complete" costs minutes more. +- **Lake vs. ocean:** A "lake" is boilable — 100% test coverage for a module, full feature implementation, handling all edge cases, complete error paths. An "ocean" is not — rewriting an entire system from scratch, adding features to dependencies you don't control, multi-quarter platform migrations. Recommend boiling lakes. Flag oceans as out of scope. +- **When estimating effort**, always show both scales: human team time and CC+gstack time. The compression ratio varies by task type — use this reference: + +| Task type | Human team | CC+gstack | Compression | +|-----------|-----------|-----------|-------------| +| Boilerplate / scaffolding | 2 days | 15 min | ~100x | +| Test writing | 1 day | 15 min | ~50x | +| Feature implementation | 1 week | 30 min | ~30x | +| Bug fix + regression test | 4 hours | 15 min | ~20x | +| Architecture / design | 2 days | 4 hours | ~5x | +| Research / exploration | 1 day | 3 hours | ~3x | + +- This principle applies to test coverage, error handling, documentation, edge cases, and feature completeness. Don't skip the last 10% to "save time" — with AI, that 10% costs seconds. + +**Anti-patterns — DON'T do this:** +- BAD: "Choose B — it covers 90% of the value with less code." (If A is only 70 lines more, choose A.) +- BAD: "We can skip edge case handling to save time." (Edge case handling costs minutes with CC.) +- BAD: "Let's defer test coverage to a follow-up PR." (Tests are the cheapest lake to boil.) +- BAD: Quoting only human-team effort: "This would take 2 weeks." (Say: "2 weeks human / ~1 hour CC.") + +## Contributor Mode + +If `_CONTRIB` is `true`: you are in **contributor mode**. You're a gstack user who also helps make it better. + +**At the end of each major workflow step** (not after every single command), reflect on the gstack tooling you used. Rate your experience 0 to 10. If it wasn't a 10, think about why.

Maybe our contributor will help make us better! + +**Calibration — this is the bar:** For example, `$B js "await fetch(...)"` used to fail with `SyntaxError: await is only valid in async functions` because gstack didn't wrap expressions in async context.
