Included Skills10

blindskills/blind/SKILL.md

Two-pass blind vs informed hypothesis test; the difference between the rankings is the finding.

diagnoseskills/diagnose/SKILL.md

Diagnose something broken, hanging, flaky, or slower than before — or a bug that already resisted one fix. Builds a red feedback loop before ranking hypotheses. Skip when the cause is already visible.

landskills/land/SKILL.md

Deploy the current work into Docker for system testing. Use when asked to land, deploy, or bring up the change, or to see it working in the real app rather than in tests.

psskills/ps/SKILL.md

Park a tangential idea mid-task and return immediately. Use when the user says p.s., "remind me later," or "note that down," or raises an aside worth keeping that would derail the current work.

simplifyskills/simplify/SKILL.md

Over-engineering review: reports what to delete from a diff or repo.

sol-budgetskills/sol-budget/SKILL.md

Speed-of-light performance budgeting for a hot path. Use to optimize, profile, or benchmark a stage; when asked if it's fast enough; on a slow frame-rate, latency, or throughput report; or when a diff touches perf/budget.md.

upstreamskills/upstream/SKILL.md

Decide where a feature belongs: our tree, the dependency, or both, in order.

verify-generated-diffskills/verify-generated-diff/SKILL.md

Verify a diff whose tests were written alongside it, so tests can't be trusted as spec. Use to review, audit, or sanity-check AI-generated code, when tests pass but aren't trusted, or a diff is too large or unfamiliar to read.

wizardskills/wizard/SKILL.md

Generate a bash wizard for a step only a human can perform — credentials, hardware, or a migration. Reach for it the moment you hit one. Skip anything the agent can do.

writing-for-agentsskills/writing-for-agents/SKILL.md

Writing documents for agents, fires when creating or editing a skill, command, rule, CLAUDE.md, or a memory file.
