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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00108 | $0.02520 |
| Opus 5.5 | $0.00043 | $0.01008 |
| Sonnet 5.5 | $0.00022 | $0.00504 |
| Haiku 4.5 | $0.00011 | $0.00252 |
Grade A, and why
athanor 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.
How it starts
The opening of the file, as written. The whole thing — 210 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Athanor
Execute a four-stage alchemical transmutation of code or data — decomposing the prima materia, purifying its essence, illuminating its target form, and synthesizing the refined output. The athanor is the furnace that maintains steady heat across all stages.
When to Use
- Transforming legacy code into modern, well-structured equivalents
- Refactoring deeply tangled modules where incremental fixes keep failing
- Converting a codebase from one paradigm to another (procedural to functional, monolith to modular)
- Processing raw, messy data into clean analytical datasets
- When simpler refactoring approaches have stalled and a full-cycle transformation is needed
Inputs
- Required: The material to transform (file paths, module names, or data sources)
- Required: The desired end state (target architecture, paradigm, or format)
- Optional: Known constraints (must preserve API, can't change database schema, etc.)
- Optional: Prior failed transformation attempts and why they stalled
Procedure
Step 1: Nigredo — Decomposition
Break the prima materia into its constituent elements. Nothing is sacred; everything is cataloged.
- Inventory the material completely:
- List every function, class, module, or data entity
- Map all dependencies (imports, calls, data flows)
- Identify hidden coupling (shared globals, implicit state, side effects)
- Surface hidden assumptions:
- What undocumented behaviors does the code rely on?
- What error conditions are silently swallowed?
- What ordering dependencies exist?
- Catalog anti-patterns and technical debt:
- God objects, circular dependencies, copy-paste duplication
- Dead code paths, unreachable branches, vestigial features
- Hardcoded values, magic numbers, embedded configuration
- Produce the Nigredo Inventory: a structured catalog of every element, dependency, assumption, and anti-pattern
Got: A complete, unflinching inventory of the material. The inventory should feel uncomfortable — if it doesn't, the decomposition isn't thorough enough. Every hidden assumption is now explicit.
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.

athanor is a skill published in the GitHub repository pjt222/agent-almanac (42 stars, last pushed 5d ago), licensed MIT. It adds 108 tokens to every session and 2,520 once invoked, about $0.0004 per session on Opus 5.5. 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.
