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 | $0.00651 | $0.00651 |
| Opus 5.5 | $0.00260 | $0.00260 |
| Sonnet 5.5 | $0.00130 | $0.00130 |
| Haiku 4.5 | $0.00065 | $0.00065 |
Grade A, and why
mathodology AGENTS.md 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 4d 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 — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Mathodology Agent Guide
Mathodology is a skills pack for mathematical modeling contests: prompts that support mathematical judgment, reproducible computation and clear scientific communication. Adapt the amount of work to the actual problem and deadline; quality follows from the argument and evidence, not from phase gates, panel scores or a predicted prize.
Skills and roles
mathodology-whole-project: entry point, installation, backup and repository use.mathodology-agent-pipeline: modeling prompts and focused collaboration.mathodology-evidence-search: literature, data, citations and licensed references.mathodology-figure-presets: scientific figure selection, design, image2 and examples.mathodology-award-gates: substantive mathematical and editorial review questions.mathodology-project-orientation: skills-only repository boundaries.mathodology-skill-authoring: maintain skills and their metadata.mathodology-dev-test-release: optional repository maintenance checks.
Roles in .claude/agents/ (Codex: .codex/agents/) are for parallel or
isolated work: brief one with a concrete question and evidence, and ask for
findings, artifacts and limitations in ordinary prose. A small task is done by
a single agent.
Figures
Load mathodology-figure-presets before figure work. It owns the image2
availability question (ask once per task; reuse any answer already in the
conversation) and the default data-driven rendering route.
Repository boundary
Maintain skills in .claude/skills/, roles in .claude/agents/ and
.codex/agents/, and short workflow prompts in .claude/workflows/. This is
the sole source of truth; .agents/skills/ is a gitignored local mirror for
Codex. Back up this project's mirror before refreshing it; do not modify other
skills or global settings.
Keep skill references, licensed exemplars and small optional utilities within
the owning skill. Contest outputs belong in a separate working project or the
ignored work/ directory. .mcp.json configures evidence search; keep
credentials and machine-specific paths out of it.
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.

mathodology AGENTS.md is an instructions file published in the GitHub repository sweetcornna/mathodology (315 stars, last pushed 4d ago), licensed MIT. It adds 651 tokens to every session, about $0.0026 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 2026-08-30.
