competition-race-condition-state-drift

Internal downstream skill for ctf-sandbox-orchestrator. CTF-sandbox workflow for race windows, ordering bugs, idempotency failures, lock gaps, concurrent worker drift, and state inconsistencies that produce decisive effects. Use when the user asks to reproduce timing-sensitive bugs, concurrent state corruption, duplicate actions, stale reads, or privilege or balance drift caused by request ordering. Use only after `$ctf-sandbox-orchestrator` has already established sandbox assumptions and routed here.

Quality

Content

80%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is concise and well-structured, with a clean three-phase workflow and a properly signaled single-level reference. The main weakness is workflow clarity: concurrent-state reproduction lacks explicit validation/verification checkpoints and a feedback loop.

Suggestions

Add an explicit validation checkpoint and a fix-and-retry loop after reproducing the race window (e.g., verify reproduced drift matches expected effect, then iterate on the minimal sequence if it does not).

Insert one concrete example sequence (request A/B ordering, the resulting stale check, and the conflicting write) inline so the Reduce step is copy-paste-ready rather than abstract.

Tie the 'What To Preserve' evidence list back to the workflow steps so each phase has a named output artifact.

DimensionReasoningScore

Conciseness

Lean and efficient with no padding or explanations of concepts Claude already knows; every section and bullet earns its place.

5 / 5

Actionability

Provides concrete, specific guidance (deterministic concurrent inputs with controlled delays, one-variable baseline-vs-race comparison, an explicit race-chain template), but as an instruction-only skill it lacks copy-paste-ready code or commands.

4 / 5

Workflow Clarity

The Map / Reproduce / Reduce sequence and 5-step Quick Start are clear, but validation checkpoints are implicit (only "Prove final state drift from a clean reset") with no validate-fix-retry feedback loop for concurrent-state reproduction.

3 / 5

Progressive Disclosure

The body is a concise overview with a single, clearly signaled one-level-deep reference to references/race-condition-state-drift.md, which exists as a real bundle file.

Description

87%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is strong: it states concrete capabilities, gives explicit natural trigger phrases, answers both what and when, and uses an explicit downstream-gating clause to stay distinct from sibling skills. Minor room remains to expand action specificity and trigger synonyms.

DimensionReasoningScore

Specificity

Lists several concrete capability areas ("race windows, ordering bugs, idempotency failures, lock gaps, concurrent worker drift, and state inconsistencies") and reproduction actions, with only minor gaps versus a fully comprehensive action list.

4 / 5

Completeness

Explicitly answers both what (CTF-sandbox workflow for race/ordering/idempotency/state-drift issues) and when ("Use when the user asks to reproduce timing-sensitive bugs..."), with concrete trigger phrases.

5 / 5

Trigger Term Quality

Includes natural trigger phrases users would say ("reproduce timing-sensitive bugs, concurrent state corruption, duplicate actions, stale reads, or privilege or balance drift"), with good but not exhaustive synonym coverage.

4 / 5

Distinctiveness Conflict Risk

Occupies a clear niche (race conditions / state drift in a CTF sandbox) and the explicit downstream-gating clause ("Use only after $ctf-sandbox-orchestrator has already established sandbox assumptions and routed here") minimizes wrong-skill triggering.
