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 | $0.00038 | $0.02212 |
| Opus 5 | $0.00019 | $0.01106 |
| Sonnet 5 | $0.00008 | $0.00442 |
| Haiku 4.5 | $0.00004 | $0.00221 |
Grade A, and why
apply-five-factors-assessment 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.

Apply Five Factors Assessment
Before committing to any competitive engagement, audit your position and your opponent's across the five strategic dimensions — 道天地将法 — and engage only where you hold an advantage in the majority.
Why This Is Best Practice
Origin: Sun Tzu opens The Art of War with this framework because he believed the outcome of every conflict is determined before it begins, by the relative standing of the two parties across these five dimensions. "The general who wins a battle makes many calculations in his temple before the battle is fought. The general who loses a battle makes but few calculations beforehand." (Ch.1, Giles trans.)
Adopted by: The five-factor framework is taught at West Point, the US Army War College, and in MBA strategy curricula as the foundational pre-engagement audit. McKinsey's strategy practice centres on "where to play and how to win" assessments that map directly to this framework. Amazon's PR/FAQ process (write the press release before building the product) is an operationalisation of the assessment-before-commitment principle.
Impact: Most strategic failures can be traced to committing resources before completing an honest assessment — overconfidence in one factor while ignoring weaknesses in others. The five-factor audit forces explicit scoring of each dimension and requires that the overall balance favours engagement before proceeding.
Why best: The framework is not a static checklist — it compares your position against a specific opponent in a specific context. A factor that favours you in one market may not in another. The comparative, context-specific scoring prevents the common failure of absolute self-assessment ("we have great people") without accounting for the opponent's standing on the same dimension.

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-five-factors-assessment is a skill published in the GitHub repository jeffreytse/grimoire-core (4 stars, last pushed 22d ago), licensed MIT. It adds 38 tokens to every session and 2,212 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.
