abstract-trace-summarizer

Performs abstract interpretation to produce summarized execution traces and high-level program behavior representations. Highlights key control flow paths, variable relationships, loop invariants, function summaries, and potential runtime states using abstract domains (intervals, signs, nullness, etc.). Use when analyzing program behavior, understanding execution paths, computing loop invariants, tracking variable ranges, detecting potential runtime errors, or generating program summaries without concrete execution.

Quality

Content

46%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 well-structured and uses progressive disclosure with real reference files, but it is heavily padded with concepts Claude already knows and offers illustrative pseudocode rather than executable guidance, with no validation checkpoints in its workflow.

Suggestions

Trim or move the conceptual exposition (abstract-domain catalogues, lattice-operation definitions, widening/narrowing theory) into references/abstract_interpretation.md so SKILL.md stays a lean overview Claude can act on.

Replace placeholder pseudocode in the Output Format and Analysis Patterns with concrete, copy-paste-ready examples or reference specific runnable snippets from references/examples.md.

Add explicit validation checkpoints to the Core Workflow, e.g. 'confirm fixpoint has converged before extracting invariants' and 'verify the summary over-approximates by spot-checking a concrete path', to lift workflow clarity above 3.

Dimension	Reasoning	Score
Conciseness	At ~480 lines the body extensively teaches concepts Claude already knows (lattice operations, widening/narrowing, CFG construction, abstract-domain catalogues), matching the 'noticeably verbose; several unnecessary explanations or padded sections' anchor rather than the mostly-efficient anchor 3.	2 / 5
Actionability	Provides structured examples and an output template, but the runnable content is illustrative pseudocode with placeholders like '[Abstract state at this point]' and '[Number of execution paths]', fitting the 'some concrete guidance but incomplete; pseudocode' anchor.	3 / 5
Workflow Clarity	Seven numbered workflow steps give a clear sequence, but there are no explicit validation checkpoints (e.g. confirming fixpoint convergence, verifying summary soundness), which caps this at anchor 3 per the validation-cap guideline.	3 / 5
Progressive Disclosure	Clear overview with well-signaled, one-level-deep references to real files (references/abstract_interpretation.md, references/examples.md, both verified present), but large conceptual sections are inlined that could live in the reference files, fitting 'good structure; minor organization gaps' anchor 4.	4 / 5

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.

The description is specific, trigger-rich, and complete, with an explicit 'Use when' clause and concrete capabilities. It is slightly below top marks on specificity and distinctiveness due to minor coverage gaps and some overlap with general program-analysis skills.

Dimension	Reasoning	Score
Specificity	Lists several concrete actions ('produce summarized execution traces', 'Highlights key control flow paths, variable relationships, loop invariants, function summaries, and potential runtime states'), matching the 'several specific actions; minor gaps' anchor rather than the fully comprehensive anchor 5.	4 / 5
Completeness	Explicitly answers 'what' (abstract interpretation producing summarized traces) and includes a concrete 'Use when analyzing program behavior, understanding execution paths...' clause, matching the anchor-5 example pattern.	5 / 5
Trigger Term Quality	Provides good natural keyword coverage ('analyzing program behavior, understanding execution paths, computing loop invariants, tracking variable ranges, detecting potential runtime errors'), though a few common synonyms are missing, fitting anchor 4 over 5.	4 / 5
Distinctiveness Conflict Risk	Occupies a distinct niche (abstract interpretation / static analysis) with clear triggers, but could overlap with broader program-analysis skills, so it sits at anchor 4 rather than the minimal-conflict anchor 5.	4 / 5
	Total	17 / 20 Passed
