web2-recon

Web2 recon pipeline — subdomain enumeration (subfinder, Chaos API, assetfinder), live host discovery (dnsx, httpx), URL crawling (katana, waybackurls, gau), directory fuzzing (ffuf), JS analysis (LinkFinder, SecretFinder), continuous monitoring (new subdomain alerts, JS change detection, GitHub commit watch). Use when starting recon on any web2 target or when asked about asset discovery, subdomain enum, or attack surface mapping.

Content

77%Weight 40%Scale 1-3

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

Highly actionable and well-sequenced recon pipeline with strong decision checkpoints, but it is a long monolithic document with some duplicated commands and no progressive disclosure into reference files.

Suggestions

Split the self-contained monitor scripts (subdomain alerts, GitHub commit watch) and the GitHub-dorking/target-scoring reference material into files under references/ and link to them one level deep, reducing the SKILL.md body length.

De-duplicate the SecretFinder and subdomain-enumeration blocks that appear in both the main pipeline and the later sections — reference the canonical block instead of restating it.

Tighten the commentary around the scoring tables and "Why this matters" notes so every line earns its place, lifting conciseness toward the lean anchor.

DimensionReasoningScore

Conciseness

Mostly efficient command-driven content that does not lecture on basics, but it repeats itself — SecretFinder commands appear in both "JS ANALYSIS" and "SECRET SCANNING IN JS BUNDLES", and subdomain enumeration is restated in "CONTINUOUS MONITORING" — and the ~430-line body could be tightened.

2 / 3

Actionability

Nearly every section is copy-paste-ready bash (e.g. the numbered Steps 0-6 pipeline, the ffuf invocations, the cron monitor scripts) with concrete flags and output paths — fully executable guidance.

3 / 3

Workflow Clarity

Multi-step processes are explicitly sequenced (Steps 0-6, the time-boxed "30-MINUTE RECON PROTOCOL") with decision checkpoints acting as validation gates — the "5-MINUTE RULE" kill signals, "Pre-Dive Hard Kill Signals", and the "TARGET SCORING — GO / NO-GO" threshold table.

3 / 3

Progressive Disclosure

The body is well sectioned with clear headers, but it is a single ~430-line monolithic file with no bundle/reference files at all, so content that could live one level deep (continuous monitoring scripts, GitHub dorking, target scoring) is all inline rather than split out.

Description

100%Weight 40%Scale 1-3

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: concrete capabilities with tool names, an explicit trigger clause, and a clearly distinct recon niche. Third-person voice is maintained throughout.

DimensionReasoningScore

Specificity

Names six concrete capability areas plus the specific tools for each ("subdomain enumeration (subfinder, Chaos API, assetfinder)", "JS analysis (LinkFinder, SecretFinder)"), listing multiple specific concrete actions rather than vague language.

3 / 3

Completeness

It explicitly answers both halves: the what (the enumerated pipeline stages) and the when (an explicit "Use when starting recon... or when asked about asset discovery, subdomain enum, or attack surface mapping" clause).

3 / 3

Trigger Term Quality

The "Use when..." clause surfaces natural terms a user would actually say — "starting recon on any web2 target", "asset discovery", "subdomain enum", "attack surface mapping" — giving good coverage of common phrasings.

3 / 3

Distinctiveness Conflict Risk

"Web2 recon pipeline" carves a clear niche (asset discovery/attack-surface mapping) distinct from exploitation or web3 skills, with triggers unlikely to fire for unrelated skills.
