structured-analytic-techniques

structured-analytic-techniques is a skill for Claude Code from Liberty91LTD/cti-skills. It costs 73 tokens per session (1,233 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 1mo 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

Start With the Evidence

The Quality of Information Check is the default first step of any diagnostic run. Before hypotheses are tested or an assessment is written, run /quality-of-information-check on the reports and articles the analysis will rest on. It resolves each one to its originating source, splits it into claims and grades each claim. ach, threat-assessment and writing-assessments prefer graded evidence and run the check themselves when handed raw material.

Skip it when the evidence already arrives as graded evidence items, when there are no documents to grade, or when the user asks to. A skipped check puts those three skills in ungraded mode: the output is labelled as ungraded and confidence is capped at Moderate. Hits in the organisation's own telemetry enter as observations graded "direct, established" (rubric rule R12). Third-party lookup results are rated through source-assessment on the Admiralty scale, which is a separate instrument: the evidence grade applies to claims from documents, and neither is converted into the other.

Technique Categories

Families follow the CIA Tradecraft Primer. The full list, one line per technique with the covering skill or "not in the pack", is in references/when-to-use.md.

Diagnostic Techniques

Purpose: Evaluate existing analysis for quality and bias.

Technique When to Use Skill
Quality of Information Check First, before any other diagnostic technique. Resolve provenance, split reports into claims, grade each claim, list gaps quality-of-information-check
Key Assumptions Check Before or after any major assessment — surface and challenge unstated assumptions key-assumptions-check
Analysis of Competing Hypotheses Multiple plausible explanations — systematically evaluate each against evidence ach
Indicators or Signposts of Change When monitoring a developing situation — define observable markers of change Not in the pack. horizon-scanning defines early warning indicators in part

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.
