Development · By garrytan

Investigates bugs, errors and stack traces in phases and requires a root-cause hypothesis to be confirmed before any fix is written.

garrytan/gstack

Builds a weekly engineering retrospective from git history: commit counts, per-person contributions, work patterns and code quality numbers over a chosen window.

garrytan/gstack

Traces a factual error the user points out back to its source (a brain page, a memory file, SOUL.md or USER.md, or a hallucination) and fixes that source instead of just noting the correction.

garrytan/gbrain

Turns an English description or Mermaid source into a diagram set: the source, an editable .excalidraw file and rendered SVG and PNG images.

garrytan/gstack

Tests a site or service for bugs, fixes what it finds with one atomic commit per fix, and reports fix evidence and a ship-readiness summary at one of three depths.

garrytan/gstack

Calls the OpenAI Codex CLI from your agent in three modes: a pass or fail review of your diff, an adversarial attempt to break it, and open consultation.

garrytan/gstack

Tests a product's developer experience live in a browser: follows the docs and getting-started flow, times it, captures errors and produces a scorecard.

garrytan/gstack

Writes missing documentation from scratch for a feature, a module or a whole project, organized as tutorial, how-to, reference and explanation pages.

garrytan/gstack

Debugs in four phases (investigate, analyze, hypothesize, implement) under one rule: no fix is made until the root cause is found.

garrytan/gstack

Read-only dashboard of the ship queue: which VERSION slots open PRs hold, which sibling workspaces have work about to ship, and the next slot to claim.

garrytan/gstack

Reviews a plan for a developer-facing product by profiling developer personas, benchmarking rivals and scoring friction, in expansion, polish or triage mode.

garrytan/gstack

Produces a weekly engineering retrospective from commit history, work patterns and code quality metrics, with trend tracking and per-person breakdowns.

garrytan/gstack

Takes finished code to a pull request: merges the base branch, runs tests, reviews the diff, bumps VERSION, updates the CHANGELOG, commits, pushes and opens the PR.

garrytan/gstack

Converts a vague idea into a precise, executable spec in five phases, files it as an issue and can start an agent on it in a fresh worktree.

garrytan/gstack

Lift a proven skill from a host repo (e.g. An agent skill from garrytan/gbrain.

garrytan/gbrain

Audits project docs against what shipped, updating README, ARCHITECTURE, CONTRIBUTING and CLAUDE.md, tidying the changelog and listing documentation debt in the PR.

garrytan/gstack

Runs a project's own type checker, linter, test runner, dead-code detector and shell linter, combines them into a weighted 0-10 score and tracks the trend.

garrytan/gstack

Merges a pull request, waits for CI and the deploy, then verifies production health with canary checks, picking up where /ship leaves off.

garrytan/gstack

Reviews an execution plan or design doc before coding, covering architecture, data flow, edge cases, test coverage and performance, one issue at a time.

garrytan/gstack

Reviews your diff against the base branch before merge, looking for SQL safety problems, LLM trust boundary violations, conditional side effects and other structural issues.

garrytan/gstack

Extract a sanitized shared team/company brain from a personal brain.
