structured-analytic-techniques

structured-analytic-techniques is a skill for Claude Code from Liberty91LTD/cti-skills. It costs 51 tokens per session (760 once invoked), scanned A, original, MIT.

An index of structured analytic techniques, which are formal methods for making reasoning visible and checking it for bias. It includes methods such as checking assumptions, assessing information quality, and testing competing explanations.

In plain words
What is it for?
Use it to choose an analysis method, expose hidden assumptions, assess source reliability, validate indicators of change, and apply contrarian analysis.
Why use it?
It helps analysts handle uncertain evidence and multiple possible explanations in a consistent way. The methods make conclusions easier to challenge and review.

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

structured-analytic-techniques 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 9d 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.

Structured Analytic Techniques (SATs) Index

SATs are formal methods that externalise analytical thinking, making it transparent, challengeable, and less susceptible to cognitive biases. Choose the right technique based on the analytical challenge.

When to Use SATs

  • When the stakes are high (wrong answer = significant consequence)
  • When multiple plausible explanations exist
  • When cognitive biases are likely (confirmation, anchoring, availability)
  • When you need to communicate your reasoning transparently
  • When building on analysis from multiple analysts

Technique Categories

Diagnostic Techniques

Purpose: Evaluate existing analysis for quality and bias.

Technique When to Use Skill
Key Assumptions Check Before or after any major assessment — surface and challenge unstated assumptions key-assumptions-check
Quality of Information Check When evidence quality is uncertain — assess source reliability and information gaps Use source-assessment skill
Indicators Validation When monitoring a developing situation — define observable markers of change Part of horizon-scanning

Contrarian Techniques

Purpose: Challenge prevailing judgments and expose blind spots.

Technique When to Use Skill
Analysis of Competing Hypotheses Multiple plausible explanations — systematically evaluate each against evidence ach
Devil's Advocate / Red Team When consensus is strong — deliberately argue the opposing position red-team-analysis
What-If Analysis Explore low-probability but high-impact scenarios Part of horizon-scanning
High-Impact / Low-Probability Ensure unlikely but catastrophic scenarios are considered Combine threat-assessment + horizon-scanning

Imaginative Techniques

Purpose: Generate new ideas, hypotheses, and indicators.

Technique When to Use Skill
Brainstorming Generate hypotheses, IOC types to collect, detection approaches No dedicated skill — apply freely
Scenario Development Explore multiple futures for strategic planning horizon-scanning
Indicators Generation Define early warning indicators for a scenario horizon-scanning

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.

structured-analytic-techniques is a skill published in the GitHub repository Liberty91LTD/cti-skills (18 stars, last pushed 1mo ago), licensed MIT. It adds 51 tokens to every session and 760 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
