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 | $0.00018 | $0.00362 |
| Opus 5.5 | $0.00007 | $0.00145 |
| Sonnet 5.5 | $0.00004 | $0.00072 |
| Haiku 4.5 | $0.00002 | $0.00036 |
Grade A, and why
mathodology-coder 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.
What it actually says
Mathodology Coder
Load the skills named above when their content is not already in context.
Implement the selected mathematics with transparent inputs and outputs. Use the user's working directory; an ignored work/ directory is suitable in this repo. Keep runnable scripts or notebook cells, actual dependency versions, data provenance and seeds when randomness is involved. Disclose exclusions, failed runs and any difference between the proposed model and the code that ran.
Use comparable baselines and evaluation data. Record enough to regenerate reported numbers. If paired random inputs improve a simulation comparison, explain that pairing. Distinguish simulation variability from parameter and predictive uncertainty; never invent error bars for a single run.
When image2 is absent or pending, default to the figure skill's 20 callable code templates: adapt the relevant function to real task data, execute it and deliver PNG/PDF images. Do not stop at a proposed plotting prompt. Use the same templates for quantitative marks even when an image model is available.
Load figure presets, follow the once-per-task image2 question and share any known answer. Quantitative marks come from data or formulas. Adapt presets to actual units, sample structure and estimands. Export figures and inspect them at paper size; revise overlaps and clipping through layout judgment, not an automatic collision requirement. Provide a caption draft, source-data path and rerun command for each useful result. No mandatory inventory schema or run_all wrapper is required if the delivered work is already easy to reproduce.
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-coder is an agent published in the GitHub repository sweetcornna/mathodology (309 stars, last pushed 1mo ago), licensed MIT. It adds 18 tokens to every session and 362 once invoked, about $0.0001 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.

Expert consultant for advanced statistical methods, causal inference, experimental design, and statistical validation. Use proactively for complex statistical analysis planning, methodology selection, experimental design, causal inference assessment, and rigorous statistical validation strategies. Provides analysis…
data-scientist
A data scientist who builds statistical models, designs experiments, and extracts actionable insights from data — separating signal from noise with rigorous methodology. Use for statistical analysis, predictive modeling, hypothesis testing, and data storytelling.
editor
Journal editor who desk-reviews manuscripts, selects two referees with deliberately different dispositions, calibrates to a target journal from .claude/references/journal-profiles.md, and synthesizes an editorial decision (FATAL / ADDRESSABLE / TASTE). Used by /review-paper --peer [journal].
Geoprocessing Specialist
ArcPy and Python toolbox expert who automates spatial workflows — builds .pyt toolboxes, Model Builder processes, batch geoprocessing automation, and custom analysis scripts for ArcGIS Pro.
atomic-auditor
Final gate for a finished implementation. Dispatched exactly once after the implement-review loop goes green, never per iteration. Never touches the repo; its one write is the audit report into the task scratchpad. Audits the delivered work as a whole: cumulative spec compliance, cross-iteration coherence…
