strategy-review

strategy-review is a skill for Claude Code from existential-birds/beagle. It costs 107 tokens per session (6,414 once invoked), scanned A, original, Apache-2.0.

A guide for critically reviewing an existing strategy document, meaning a plan for responding to an important business, product, team, or career challenge.

In plain words
What is it for?
Use it to examine a strategy’s diagnosis, guiding policy, actions, assumptions, and testability, with optional business-analysis frameworks.
Why use it?
It looks for weak reasoning, hidden assumptions, gaps, and failure paths that may cause the plan to break during execution.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

strategy-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Strategy Review

Pressure-test strategy documents to find where they'll break before reality does it for you. The primary job isn't to evaluate prose quality or check formatting — it's to find the gaps, hidden failure paths, and under-accounted risks that will kill the strategy in execution. A strategy that survives this review has a meaningfully better chance of surviving contact with the real world.

This skill complements the strategy-interview skill. Strategy-interview helps build a strategy through guided conversation; strategy-review subjects an existing strategy to rigorous adversarial evaluation using the same kernel framework (diagnosis, guiding policy, coherent actions) and bad-strategy filter.

What makes this different from generic feedback

Most strategy feedback falls into two useless categories: vague praise ("this is really thoughtful") or surface-level nitpicking ("consider adding a timeline"). Neither helps the author see whether their thinking actually holds up under stress.

This review does three things that generic feedback doesn't:

  1. Tests structural integrity — whether the logical chain from diagnosis through guiding policy to coherent actions actually holds together, or whether the "therefore" between them is secretly an "and also."
  2. Hunts for failure paths — not just what's wrong with the document, but what goes wrong in the real world because of what's missing. The slow drift scenario, the capability gap that stalls the load-bearing action, the competitor response nobody modeled, the political resistance the strategy pretends doesn't exist.
  3. Surfaces invisible assumptions — every strategy is a bet, but most strategies don't name their bets. This review finds the load-bearing assumptions the author hasn't stated and maps the risk of each one being wrong.

Before you start

Read references/review-dimensions.md — it contains the seven evaluation dimensions and their criteria. This is the backbone of the review. Keep it in working memory throughout.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
