andreessen

Marc Andreessen-mode decision and productivity skill. A blunt, market-first operator that pressure-tests ideas, ventures, features, and career bets through Andreessen's actual frameworks — market dominates team and product; the only milestone that matters is product/market fit; bias to build over deliberate. Use when the user says 'andreessen', 'pmarca mode', 'should I build this', 'is there a market', 'are we at product/market fit', 'pmf check', 'pressure-test this idea', 'be brutal about this venture', 'market-first take', or wants a no-disclaimers, no-hedging, confidence-leveled verdict on whether something is worth pursuing. Also provides the 3x5-card + Anti-Todo personal productivity routine. Runs on a fixed anti-sycophancy operating prompt: leads with the strongest counterargument, never validates premises, uses explicit confidence levels, never apologizes for disagreeing. Not for polite brainstorming — this skill exists to tell you the market is dead when it is.

Quality

Content

63%Weight 40%Scale 1-5

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

The body is well-structured and actionable with concrete commands and a clear sequenced workflow, but it suffers from restated rules across multiple sections (conciseness) and — more seriously — references 12 bundle files that are absent from the skill, breaking progressive disclosure and the runnability of the tool commands.

Suggestions

Ship the referenced bundle files (references/operating_prompt.md, the canon files, scripts/*.py, assets/*.md) so the progressive-disclosure structure actually resolves and the CLI commands run.

Collapse the Hard Rules and Anti-Patterns sections into the Operating Prompt / Workflow where the rules are already stated, eliminating the repeated counterargument-first, confidence-level, and no-sycophancy rules.

Verify the script argument flags documented in the examples (e.g. --ellis-pct, --must-do) match the actual scripts' interfaces once they are added.

DimensionReasoningScore

Conciseness

Mostly efficient persona-specific content Claude would not already know, but the same rules are restated across three sections — "Lead with the strongest counterargument" appears in Operating Prompt, Workflow step 4, and Hard Rules #3, and the no-sycophancy / confidence-level rules are repeated verbatim in Operating Prompt, Hard Rules, and Anti-Patterns — which is padding that could be tightened.

3 / 5

Actionability

Provides concrete executable CLI commands with real arguments (e.g. "python scripts/market_first_evaluator.py --size 8 --growth 7 --timing 9 --pull 8 --team 6 --product 5") and a numbered interrogation with recommended answers; the gap is that the referenced scripts/ files are not present in the bundle, so the commands are not actually runnable as-is.

4 / 5

Workflow Clarity

A clearly sequenced four-step workflow (route → interrogation one-at-a-time → score with tools → verdict in voice) with deterministic checkpoints (sub-4 market hard kill gate, Sean Ellis 40% gate, 3-5 cap); minor validation gaps keep it below a 5.

4 / 5

Progressive Disclosure

The body describes a well-signaled, one-level-deep structure across references/, scripts/, and assets/ with one-line descriptions for each file, but none of those 12 referenced files actually exist in the bundle — so navigation leads to missing files and the disclosure structure does not resolve in practice.

Description

95%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

An excellent description: concrete capabilities, comprehensive natural trigger phrases, explicit what-and-when, and a clearly distinct persona niche. The only flaw is a minor second-person slip ("tell you") in the closing line.

Suggestions

Rephrase "this skill exists to tell you the market is dead when it is" to third person (e.g. "tells the user the market is dead when it is") to fully comply with the third-person voice convention.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — "pressure-tests ideas, ventures, features, and career bets", "verdict on whether something is worth pursuing", "3x5-card + Anti-Todo personal productivity routine" — with comprehensive coverage; docked one point because the closing phrase "this skill exists to tell you the market is dead" slips into second-person voice, which the rubric penalizes.

4 / 5

Completeness

Explicitly answers both what ("market-first operator that pressure-tests ideas... Also provides the 3x5-card + Anti-Todo routine") and when ("Use when the user says...") with concrete trigger phrases.

5 / 5

Trigger Term Quality

Comprehensive coverage of natural trigger phrases a user would actually say — "andreessen", "pmarca mode", "should I build this", "is there a market", "pmf check", "pressure-test this idea", "be brutal about this venture", "market-first take" — including synonyms and persona-specific variants.

5 / 5

Distinctiveness Conflict Risk

Clear niche — a Marc Andreessen persona with distinct triggers ("andreessen", "pmarca mode", "pmf check") — that is unlikely to fire for unrelated skills; minimal conflict risk.
