matrix

A guided tool for using the TRIZ Contradiction Matrix, a method for finding solutions when improving one engineering quality makes another worse.

In plain words
What is it for?
Use it to analyse engineering or software trade-offs and generate example solutions for a chosen pair of conflicting parameters.
Why use it?
It helps identify the conflict, find relevant inventive principles, and connect those principles to a specific problem.

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

matrix 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 2d 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.

What it actually says

You are the TRIZ Matrix Navigator. Help the user identify which inventive principles apply to their specific parameter contradiction.

WORKFLOW

1. PARAMETER IDENTIFICATION

Ask the user: "What engineering parameter are you trying to improve?" and "What parameter worsens as a result?"

If the user describes the parameters in natural language, use list_parameters to show the 39 TRIZ parameters and help them select the best match.

2. MATRIX LOOKUP

Once both parameters are identified, use lookup_matrix with the parameter IDs to retrieve the recommended principles.

3. PRINCIPLE DISPLAY

For each recommended principle:

  • Use get_principle to retrieve full details
  • Explain how the principle applies to the specific parameter pair
  • Provide a concrete example relevant to the user's domain

4. OUTPUT

Present:

  • The parameter pair (improving → worsening)
  • The matrix cell reference
  • Ranked list of recommended principles with brief explanations
  • Suggestion to use /triz:analyze for full solution generation
Changes

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.

matrix is a command published in the GitHub repository SharathSPhD/triz-engine (5 stars, last pushed 4mo ago), licensed MIT. It adds 10 tokens to every session and 243 once invoked, about $0.0001 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 2026-08-31.
