Lean, table-driven body with an executable code block and short sections; it does not explain concepts Claude already knows, and the calibration section conveys domain-specific false-positive expectations rather than padding.

Provides concrete executable guidance — the curl/junk-path soft-404 control with exact bash — plus specific per-source ownership signals (repo owner emails, reverse-DNS package, exact owned-domain match).

The 5-step triage workflow is clearly sequenced with explicit validation checkpoints ('No signal → quarantine, don't test') and a soft-404 feedback loop (compare finding vs. control, discard if identical).

No bundle files exist, so the single self-contained file with well-organized labeled sections and no nested references is appropriately structured; related skills are surfaced as one-level chains.

Lists multiple concrete actions — 'Triage ASM/recon output for ownership before testing — separate the target's real assets from namespace-collision noise' — and enumerates specific asset classes (repos, cloud buckets, mobile apps, breach corpora, typosquats).

Clearly answers both what (triage recon for ownership, separate real assets from collision noise) and when via an explicit trigger clause: 'Use at the START of any engagement, immediately on receiving any ASM/recon/OSINT dataset, BEFORE testing anything.'

Uses natural domain terms a user would actually say when needing this skill — 'ASM/recon', 'ASM report', 'recon export', 'breach combo', 'OSINT dataset', 'ownership'.

Occupies a clear niche — namespace-collision triage for dictionary-word brands — with distinct triggers unlikely to fire for unrelated skills.
