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

78%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.

A well-built operational skill: deterministic scoring tools, a defined workflow with routing, and exemplary progressive disclosure with a clean one-level-deep bundle. The main cost is redundancy — the voice rules are enforced in three separate sections, which inflates token cost without adding new guidance — and the workflow lacks an explicit recovery path for ambiguous inputs or disputed scores.

Suggestions

Merge 'Hard Rules' 3–7 and the overlapping 'Anti-Patterns' entries into the Operating Prompt section (or cut the restatements down to a single cross-reference) — the voice rules currently appear three times, which is the body's largest avoidable token cost.

Trim the positioning prose in the intro ('Where a generic advisor balances and reassures...') and the 'Andreessen-lens counterpart' paragraph to one sentence; the portability blockquote plus the workflow already establish what the skill is.

Add a short error-recovery step to the workflow: what to do when tool inputs are ambiguous or unavailable (e.g., 'ask the user for the missing score, default to unknown, or derive it from their answers') and how to handle a user disputing a scored verdict.

DimensionReasoningScore

Conciseness

Mostly efficient — the workflow, forcing questions, and tool sections are tight — but the behavioral rules are restated three times (the Operating Prompt binding rules, Hard Rules 3–7, and Anti-Patterns), and the positioning intro ('Where a generic advisor balances and reassures, this skill takes a position') is padding that could be trimmed. Not a 2 because each section still carries operational content rather than concept explanation Claude already knows.

3 / 5

Actionability

Fully executable guidance: copy-paste-ready invocations for all three scripts with flags and expected outputs, a routing table mapping user intent to tools, six forcing questions each with a recommended answer, and a defined verdict vocabulary (BUILD-POUR-FUEL / MARKET-FIRST-DERISK / KILL-OR-REPICK-MARKET). The common cases are covered.

5 / 5

Workflow Clarity

A clear four-step sequence (route → interrogate one question at a time → score with tools → deliver verdict) with deterministic checkpoints built into the scripts (sub-4 market hard kill gate, Sean Ellis 40% gate). Not a 5 because there is no explicit error-recovery loop — e.g., what to do when inputs are ambiguous or the user disputes the scored verdict beyond 'don't capitulate without new evidence'.

4 / 5

Progressive Disclosure

The body is a genuine overview: every referenced file exists (verified against the bundle listing), references are one level deep with no chained indirection, and each link is annotated with its purpose and source count. Verbatim prompt, canon, worksheet, and worked examples are correctly split into references/ and assets/ rather than inlined.

Description

91%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.

A strong description: it names concrete capabilities, includes an explicit and richly populated 'Use when' trigger list with synonyms, and draws a clear boundary around the persona. The only deductions are a second-person slip in the closing clause and a few generic trigger phrases that create minor overlap risk with similar advisory skills.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'pressure-tests ideas, ventures, features, and career bets', '3x5-card + Anti-Todo personal productivity routine', 'leads with the strongest counterargument' — with comprehensive coverage of the skill's behavior. Not a 5 because the closing clause 'this skill exists to tell you the market is dead when it is' slips into second person, which the guidelines penalize by one point.

4 / 5

Completeness

Explicitly answers both what (market-first pressure-testing through Andreessen's frameworks, PMF checks, the 3x5-card + Anti-Todo routine, a fixed anti-sycophancy operating posture) and when ('Use when the user says...' with a concrete list of trigger phrases), plus an explicit exclusion boundary ('Not for polite brainstorming').

5 / 5

Trigger Term Quality

Comprehensive natural trigger phrases with synonyms: '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'. These are exactly the phrases a user would naturally say when they want this skill.

5 / 5

Distinctiveness Conflict Risk

A clear persona niche with distinct named triggers ('andreessen', 'pmarca mode', 'pmf check') and an explicit boundary statement. Not a 5 because several triggers ('should I build this', 'is there a market') are generic enough to overlap with closely related venture-advisor or sibling operator skills.
