The body is dense with executable commands and task-specific operational knowledge (e.g., the buffer-flush gotcha, CRM-field causality warning) that Claude would not already know, and detail has been aggressively pushed to references (changelog notes a 650→~250 line trim). It is not level 2 because there is little padding to tighten, and not level 1 since no generic concepts are re-explained.

Every step ships copy-paste-ready commands (`deepline enrich ...`, `python3 scripts/analyze_signals.py ...`, a concrete CSV format and a dedup Python snippet), matching the level-3 anchor of fully executable, specific examples. It is not level 2 because guidance is complete rather than pseudocode, and not level 1 since nothing is merely described.

Steps 0–7 are explicitly sequenced with validation checkpoints — the Step 3 wc -l row-count gate, Step 3.5 red-flag review, and mandatory user approval before paid/batch steps — giving the feedback loops the level-3 anchor requires. It is not level 2 because checkpoints are explicit and recovering, not implicit; not level 1 because the sequence and validation are present.

The body is an overview that signals one-level-deep references ("Read `references/...`") and lists all 12 real bundle files (9 references + 3 scripts) with one-line descriptions in a References section; every referenced path exists on disk. It is not level 2 because content is appropriately split and clearly signaled, and not level 1 since references are a single level deep with easy navigation.

"Discover niche first-party signals that differentiate Closed Won vs Closed Lost accounts... build account scoring models and prospecting criteria" names multiple concrete actions (signal discovery, differentiation, model/criteria building) and uses third-person voice, matching the level-3 anchor listing several specific actions. It is not level 2 because the actions are comprehensive rather than partial, and there is no vague filler to drop it to 1.

It states the "what" (discover/build scoring models and prospecting criteria) and an explicit "when" ("Use when the user provides won/lost customer domain lists and wants differential signals..."), satisfying the level-3 anchor requiring both with explicit triggers. It is not level 2 because the trigger clause is explicit rather than implied, and not level 1 because neither what nor when is missing.

"Triggers: ICP analysis, niche signals, won vs lost analysis, differential signals, signal discovery, ICP signal report, account scoring signals, lead scoring, first-party signals, buyer signals" gives broad coverage of natural terms a user would say. It is not level 2 because both common phrasings and variations are present, and not level 1 since none of it is generic jargon.

"Niche first-party signals... Closed Won vs Closed Lost accounts for ICP analysis" carves a clear niche with distinct triggers unlikely to fire for unrelated skills. It is not level 2 because the triggers are specific rather than broadly overlapping; the prerequisite pointer to deepline-gtm is complementary, not a conflict.
