perl-security

Comprehensive Perl security covering taint mode, input validation, safe process execution, DBI parameterized queries, web security (XSS/SQLi/CSRF), and perlcritic security policies. Use when reviewing Perl input handling, process execution, DBI queries, or web-facing code.

Quality

Content

78%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 highly actionable, well-organized security reference with excellent executable examples and a useful checklist, slightly held back by a few concept re-explanations and by keeping all ~490 lines inline rather than offloading detail sections to one-level-deep reference files.

Suggestions

Split detail-heavy sections (perlcritic policy catalog, framework-specific web/session security, anti-patterns) into references/ files linked one level deep from SKILL.md, keeping the core patterns and checklist inline.

Drop explanations of concepts Claude already knows, e.g., the definitional sentences about what taint mode and catastrophic backtracking are, keeping only the pattern guidance.

Remove the 'When to Activate' section, which duplicates the frontmatter description's 'Use when' clause.

DimensionReasoningScore

Conciseness

The body is dominated by lean Good/Bad code pairs with minimal framing, but includes a few explanations of concepts Claude already knows ('Perl's taint mode (-T) tracks data from external sources...', 'Catastrophic backtracking occurs with nested quantifiers...') and a 'When to Activate' section that duplicates the frontmatter description — minor instances that could be trimmed.

4 / 5

Actionability

Fully executable, copy-paste-ready guidance throughout: complete validation subs, safe_open/safe_path/run3 examples, a full .perlcriticrc configuration, CI commands, and an anti-patterns catalog with concrete vulnerable lines.

5 / 5

Workflow Clarity

The 'How It Works' section gives a clear application order ('Start with taint-aware input boundaries, then move outward...') and the Quick Security Checklist plus perlcritic CI integration serve as verification checkpoints, but no explicit validate-fix-retry feedback loop is laid out.

4 / 5

Progressive Disclosure

The ~490-line body is well-organized with clear headers, but no bundle files exist and everything is inlined in SKILL.md; content that naturally belongs in separate reference files (the perlcritic policy catalog, framework-specific web security, the anti-patterns catalog) is not split out.

Description

92%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: specific, comprehensive, in third person, with an explicit and concrete 'Use when' trigger clause. The only weakness is modest synonym/extension coverage (e.g., .pl, CGI, framework names) in the trigger terms.

DimensionReasoningScore

Specificity

The description enumerates multiple concrete capabilities — 'taint mode, input validation, safe process execution, DBI parameterized queries, web security (XSS/SQLi/CSRF), and perlcritic security policies' — with no notable coverage gaps relative to the skill body, matching the comprehensive multi-action anchor.

5 / 5

Completeness

Both 'what' (the six enumerated security capability areas) and 'when' (an explicit 'Use when reviewing...' clause with concrete trigger phrases) are clearly and explicitly stated.

5 / 5

Trigger Term Quality

'Use when reviewing Perl input handling, process execution, DBI queries, or web-facing code' provides good natural keywords, but common variations users might say (.pl/.pm files, CGI, Mojolicious, 'Perl script') are absent, placing it at good-but-not-comprehensive coverage.

4 / 5

Distinctiveness Conflict Risk

Perl-specific tooling names (taint mode, DBI, perlcritic) establish a clear niche with distinct triggers and minimal risk of firing for non-Perl skills.
