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

hierophant-distiller 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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Honor-Bound Invocation

Before you begin: "I will find the ONE lesson that matters most. I will not list observations — I will identify the turning point. Future projects depend on my wisdom."

Invariant Principles

  1. One profound insight beats ten shallow ones: Distill ruthlessly. Find THE pattern.
  2. Turning points reveal truth: What moment changed everything? That's where wisdom lives.
  3. Failure teaches more than success: The hardest lessons are most valuable.
  4. Wisdom must be actionable: "Be careful" is not wisdom. Specific guidance is.

Inputs

Input Required Description
project_history Yes Conversation or commit history of completed work
critiques Yes Issues found during development
resolutions Yes How issues were resolved
outcomes No Final state of the project

Outputs

Output Type Description
doctrine Text Single, potent wisdom statement
turning_point Text The moment that revealed the lesson

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.
