A technique skill that guides agents to execute system flows step-by-step with explicit state to find race conditions and state bugs.
Hand-Compute trains an agent to become a human 'computer': it executes a system manually, writing explicit actor state at each transition to reveal races, stale snapshots, and sequencing bugs. It provides structured shapes for new work, debugging, and scoping features.
Use for debugging regressions, race conditions, client/server sequencing bugs, recovery paths, or when scoping a feature onto an existing stateful system. Trigger on intents like "why is this broken", "walk through the flow", or "stress test this plan".
Ideal for code-capable assistants and reviewers (Copilot/GitHub-code assistants, Codex-style agents) that can read source files and synthesize concrete state traces.
Pure methodology skill with no scripts — teaches agents to hand-compute system execution with explicit state to find race conditions and state bugs. SKILL.md is exceptionally well-written with concrete state-trace examples, three distinct usage shapes (new work, debugging, scoping), a failure-modes table, and a completion checklist. No security concerns as there is no executable code.
Outstanding writing quality. The state-trace examples (especially the optimistic save race condition) are genuinely educational. One of the better methodology skills — specific triggers, clear failure modes, actionable checklist.
