hunt-source-leak

Hunt source code and build artifact leakage — JavaScript source maps (.js.map) reconstructing TypeScript/ES6 source, Swagger/OpenAPI JSON endpoint discovery, .env/.git exposure, webpack chunks with hardcoded secrets, robots.txt/security.txt recon, build-info files, asset-manifest.json API route discovery, .DS_Store file listing. Use at the START of every recon session — these findings often unlock the entire attack surface.

Content

65%

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-structured recon playbook that is held back by repeated scan-loop boilerplate, missing inline feedback loops for batch operations, and a monolithic layout with no progressive disclosure.

Suggestions

Extract the repeated curl-status scan loop (Phases 1, 3, 5) into a single reusable shell function so each phase only supplies its path list.

Add inline per-phase validation/error-recovery checkpoints (e.g. what to do when a 200 returns an HTML login page rather than the expected JSON) instead of only a terminal checklist.

Move the long path-wordlists (DEBUG_PATHS, SWAGGER_PATHS) and the Tools section into reference files referenced one level deep from SKILL.md to apply progressive disclosure.

DimensionReasoningScore

Conciseness

Mostly lean executable bash with minimal conceptual filler, but the curl-status path-scan loop boilerplate is repeated nearly verbatim across Phases 1, 3, and 5 and could be collapsed into a shared function.

2 / 3

Actionability

Copy-paste-ready bash commands and complete embedded Python scripts (e.g. source-map reconstruction, swagger path extraction) give concrete, executable guidance throughout.

3 / 3

Workflow Clarity

Phases are clearly sequenced with a 'Run First' directive and an end-of-doc validation checklist, but batch path-scans lack inline error-recovery feedback loops, capping this dimension at 2 per the rubric's batch-operation note.

2 / 3

Progressive Disclosure

Sections are well-organized (crown jewels, phases, chain table, tools, validation), but the ~275-line body is monolithic with no external references, and path lists / tool detail that could be split out are inline.

Description

100%

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: third-person, specific, with an explicit use-trigger and a well-scoped niche. Its only weakness is verbosity — the single long enumeration could be trimmed without losing capability information.

DimensionReasoningScore

Specificity

Lists many concrete actions — 'reconstructing TypeScript/ES6 source', 'Swagger/OpenAPI JSON endpoint discovery', '.env/.git exposure', '.DS_Store file listing' — across distinct leak vectors rather than vague language.

3 / 3

Completeness

Answers both what (the enumerated leak types) and when via the explicit trigger 'Use at the START of every recon session — these findings often unlock the entire attack surface'.

3 / 3

Trigger Term Quality

Natural recon terms a user would say are well covered: 'source maps', '.js.map', 'Swagger/OpenAPI', '.env', '.git', 'webpack', 'robots.txt', 'security.txt', 'build-info', 'asset-manifest.json', '.DS_Store'.

3 / 3

Distinctiveness Conflict Risk

A clear niche (source/build-artifact leakage within recon) with distinct, specific triggers unlikely to collide with other skills.
