batch

Execute batch operations on multiple files in parallel. Automatically discovers files, splits into chunks, and processes with parallel worker agents. Use `/batch` followed by operation and file pattern.

Quality

Content

65%

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

The body is highly actionable with concrete templates and clear sequencing, but it carries redundancy (a duplicated constraints table), lacks a verification feedback loop for a batch operation, and is monolithic rather than progressively disclosed.

Suggestions

Add a post-batch verification step (e.g., re-run lint/typecheck or confirm files still parse) before reporting success, creating a validate→fix→retry loop for this destructive/batch operation.

Remove the 'Constraints and Limits' table or replace it with a one-line pointer to Step 2, since it duplicates the chunking and size limits already stated there.

Move the worker-agent prompt template, full usage examples, and dry-run block into reference files (e.g., references/prompt-template.md, examples.md) and link to them from the overview to enable progressive disclosure.

Dimension	Reasoning	Score
Conciseness	The content is instruction-dense and not padded with basic concepts, but the 'Constraints and Limits' table duplicates Step 2 rules and the three full usage-example flows add length that could be tightened.	2 / 3
Actionability	Provides copy-paste-ready guidance — a concrete chunking table, a full worker-agent prompt template, explicit glob/exclusion lists, and an exact output format — well beyond pseudocode.	3 / 3
Workflow Clarity	The 5-step sequence is clear with discovery checkpoints (empty-batch abort, 50/100-file warnings), but as a batch/destructive operation it lacks a post-modification validation/verification feedback loop, capping it at 2.	2 / 3
Progressive Disclosure	Sections are well-organized, but the ~295-line skill is monolithic with no bundle files — content like the prompt template, exclusions, and examples is all inline rather than split into one-level-deep references.	2 / 3

Description

67%

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 specific and distinct, naming several concrete actions and occupying a clear niche, but it provides invocation syntax rather than explicit 'use when' trigger guidance and lacks coverage of natural phrasing variations.

Suggestions

Add an explicit 'Use when...' clause with scenario-based triggers, e.g. 'Use when applying an operation across many files at once or when the user asks to batch-process files.'

Broaden trigger terms to include natural variations users would say, such as 'apply to all files', 'across many files', or 'in bulk'.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'discovers files, splits into chunks, and processes with parallel worker agents' — matching the top anchor for listing several specific concrete actions.	3 / 3
Completeness	Clearly states what the skill does, but the 'when' is given only as invocation syntax ('Use `/batch` followed by operation and file pattern') rather than an explicit scenario-based trigger, capping completeness at 2 per the missing-'Use when' guideline.	2 / 3
Trigger Term Quality	Has relevant natural terms ('batch operations', 'files in parallel') but is tied to the `/batch` invocation syntax and lacks common variations like 'apply to all files' or 'across many files'.	2 / 3
Distinctiveness Conflict Risk	The parallel-worker-agent framing plus the explicit `/batch` invocation carve a clear niche unlikely to trigger for the wrong skill.	3 / 3
