Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00048 | $0.01695 |
| Opus 5 | $0.00024 | $0.00847 |
| Sonnet 5 | $0.00010 | $0.00339 |
| Haiku 4.5 | $0.00005 | $0.00169 |
Grade A, and why
apply-ansoff-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 6d 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.

Apply Ansoff Matrix
Classify a growth move by whether it targets an existing or new product, and an existing or new market, then size the risk and required capability accordingly — instead of treating every growth initiative as equally risky or resourcing it on gut feel.
Why This Is Best Practice
Origin: Igor Ansoff introduced the matrix in "Strategies for Diversification" (Harvard Business Review, 1957) to give executives a structured way to classify growth options by what actually changes — the product being sold, the market being sold into, or both — rather than treating "growth" as a single undifferentiated goal.
Adopted by: The Ansoff Matrix is standard content in essentially every accredited MBA strategy and marketing curriculum worldwide and is used as a first-pass growth-option screen by corporate strategy and corporate development teams before committing resources to a specific initiative. It underlies common go-to-market decisions: expanding sales effort in a current market (penetration), entering a new geography with an existing product (market development), launching a new product to existing customers (product development), or entering a new market with a new product (diversification).
Impact: The core empirical finding the matrix formalizes is that risk and failure rates increase sharply moving from penetration to diversification — diversification (new product, new market simultaneously) combines two independent sources of uncertainty (will the product work, will the market respond) and is consistently the highest-failure-rate growth category in post-mortems of failed corporate growth initiatives. Classifying a move on the matrix before committing capital surfaces this compounded risk instead of hiding it inside a single "growth initiative" label.
Why best: Without this classification, organizations routinely resource a diversification bet (new product, new market) with the same confidence and timeline as a penetration move (existing product, existing market) — because both are described internally as "growth." The matrix forces the distinction to be explicit before resourcing, so risk tolerance, timeline, and required validation steps can be matched to the quadrant instead of defaulting to whatever confidence level the loudest advocate projects.
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.

apply-ansoff-matrix is a skill published in the GitHub repository jeffreytse/grimoire-core (4 stars, last pushed 20d ago), licensed MIT. It adds 48 tokens to every session and 1,695 once invoked, about $0.0002 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.
