parallel-execution-optimizer

Speed up a task by turning it into a dependency graph of parallel lanes with a lane matrix, batched reads and checks, write surfaces isolated by file, worktree, branch, or service, and a final verification table. Use when the user wants a task done much faster through parallel work, concurrent agents, batched tool calls, isolated worktrees, or many independent verification lanes without losing correctness.

Quality

Content

82%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.

A tight, well-structured instruction-only skill body: an explicit step sequence, a concrete lane-matrix and output template, real validation gates, and a useful failure-modes list, all with no wasted tokens. Its only real gap is the absence of any executable example (commands or batched tool-call patterns) that would move the guidance from specific-but-abstract to copy-paste ready.

Suggestions

Add one small executable example of a batched read/check (e.g., a single multi-tool-use style block or a concrete shell command batching several searches) to raise actionability.

Add an explicit fix-and-retry rule for failed verification entries in the final verification table (what to do when a lane's check does not pass) to complete the workflow's feedback loop.

Consider moving the lane-matrix and output-shape templates into a references/ file to slim the body further and strengthen progressive disclosure.

DimensionReasoningScore

Conciseness

The 75-line body is lean with zero padding: every section (Core Pattern, Lane Matrix, Execution Rules, Output Shape, Failure Modes) adds guidance Claude does not already know, and nothing explains general concepts. Matches anchor 5 (every token earns its place).

5 / 5

Actionability

Concrete, specific guidance throughout — a filled-in lane-matrix template, an output-shape template, and exact rules like 'Only run lanes in parallel when their write surfaces do not collide'. As an instruction-only skill code absence is not penalized, but there are no executable command examples (e.g., a concrete batched tool call or worktree command), leaving minor gaps at anchor 4 rather than 5.

4 / 5

Workflow Clarity

The 7-step Core Pattern is clearly sequenced with validation checkpoints — 'End with a verification table', 'Merge only after evidence shows the lanes are compatible' — and an error-recovery loop ('If a lane discovers a blocker... pause dependent lanes and update the matrix'). It sits at anchor 4 rather than 5 because recovery from a failed verification is not spelled out as an explicit fix-and-retry loop.

4 / 5

Progressive Disclosure

Well-organized sections with clear headers and a self-contained ~75-line body; nothing that clearly belongs in a separate file is inlined and no references are buried. It does not qualify for the under-50-line exception to anchor 5, and the lane-matrix/output templates could conceivably live in references, so anchor 4 fits best.

Description

83%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.

A strong description: it answers what and when explicitly, uses natural trigger language, and stays concise without padding. Its main limitation is reliance on the skill's own vocabulary ('lane matrix', 'write surfaces') rather than plain, user-recognizable action terms, and its trigger list misses a few common phrasings users would naturally say.

DimensionReasoningScore

Specificity

The description lists several concrete actions — 'lane matrix, batched reads and checks, write surfaces isolated by file, worktree, branch, or service, and a final verification table' — but the actions are framed in skill-internal jargon ('dependency graph of parallel lanes', 'write surfaces') rather than plain operations. Falls between anchor 4 (several specific actions, minor gaps) and anchor 5 (comprehensive, plainly concrete).

4 / 5

Completeness

Both parts are explicit: the 'what' enumerates concrete capabilities and the 'when' opens with 'Use when the user wants a task done much faster through parallel work, concurrent agents, batched tool calls, isolated worktrees...'. This matches anchor 5 (clear what AND when with concrete trigger phrases).

5 / 5

Trigger Term Quality

Natural phrases users would say are present: 'parallel work', 'concurrent agents', 'batched tool calls', 'isolated worktrees', 'done much faster'. Common variations like 'run these at the same time', 'spawn agents', or 'in parallel' are missing, so it does not reach anchor 5 but clearly exceeds anchor 3's partial coverage.

4 / 5

Distinctiveness Conflict Risk

It carves a distinct niche (parallelization strategy with isolated write surfaces and verification lanes) with trigger terms unlikely to fire for unrelated skills. Minor overlap risk with general agent-orchestration or code-review skills keeps it at anchor 4 rather than 5.
