Conciseness

The body is dense and operational — API endpoints, exact query strings, script invocations, and an output template with almost no concept explanations Claude already knows. Not 5: the 10-bullet 'Anti-Patterns To Reject' section substantially duplicates the Error Handling table, and the maintainer footer (source spec, build pattern, '/cs-grill-with-docs' re-grill note) is internal bookkeeping that earns no runtime tokens. Not 3: the padding is minor relative to the whole — no multi-paragraph explanations of known concepts.

Actionability

Fully executable guidance throughout: exact API calls ('reddit.com/search.json', 'search?query=<topic>&numericFilters=created_at_i><timestamp>&tags=story'), concrete script commands with flags ('scripts/time_window_calculator.py --window <Nd>', 'citation_tracker.py --action record_sent --session NAME --query "..."'), a copy-paste-ready output template, and a runnable Phase-4 import command. Not 4: the common cases are covered end-to-end with specific commands, not just patterns.

Workflow Clarity

Phases 0–4 are explicitly sequenced with parallel/sequential boundaries stated, stop conditions ('After Q4 (or earlier with dependency skips)... Max 4 questions, never bundle'), a retry policy with failure ceilings, a three-count audit validation loop, and a comprehensive Error Handling table with recovery behavior per failure mode. Not 4: validation checkpoints and feedback loops (retry once → stop after 3 failures, refuse-mush pushback, never deliver an empty file) are explicit and pervasive.

Progressive Disclosure

SKILL.md is an operational overview with well-signaled, one-level-deep references — 'See references/research_pack_conventions.md for the canon', 'See references/cross_platform_synthesis.md for detection heuristics' — plus a Tooling table and a References section describing each file's role; all six referenced files exist in the bundle. Not 4: every reference is signaled at point of use, listed with roles, exactly one level deep, and the remaining inline content (queries, output template) is core workflow that belongs in the main file.

Specificity

The description lists multiple concrete actions: 'takes the pulse of any topic across Reddit, Hacker News, the open web, and optionally X/Twitter', 'clarifies topic specificity, angle (trend/sentiment/problems/opportunities/comparison), time window, and platform scope before searching', and 'Returns a synthesized briefing with citations, engagement metrics, and cross-platform pattern analysis' — comprehensive coverage in third-person voice. Not 4: there are no minor gaps in the action coverage; sources, intake behavior, and output form are all specified.

Completeness

It explicitly answers both questions: 'what' is a multi-source recency research skill producing a synthesized briefing with citations and cross-platform pattern analysis, and 'when' is an explicit 'Use when the user requests...' clause with concrete trigger phrases and example phrasings. Not 4: the 'when' is not merely present — it enumerates seven concrete trigger phrases, matching the anchor-5 example pattern.

Trigger Term Quality

Natural user phrasings are comprehensively covered with synonyms: 'pulse on [topic]', 'what's happening with [topic]', 'what are people saying about [topic]', 'current conversation about [topic]', 'take the pulse of [topic]', 'trending: [topic]', 'find me info on [topic]', plus use cases ('competitor research, trend discovery, tool comparisons, and audience sentiment analysis'). Not 4: virtually no natural variation a user would say for this intent is missing.

Distinctiveness Conflict Risk

The recency-focused, multi-platform-briefing niche is clearly distinct, but generic triggers like 'find me info on [topic]', 'trending: [topic]', and 'tool comparisons' could overlap with general web-research or search skills. Not 5: those catch-all phrasings create minor conflict risk with broader research skills; not 3: the core triggers ('pulse on', 'take the pulse of', 'what are people saying about') are distinctive to this skill.
