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 | $0.00053 | $0.02054 |
| Opus 5.5 | $0.00021 | $0.00822 |
| Sonnet 5.5 | $0.00011 | $0.00411 |
| Haiku 4.5 | $0.00005 | $0.00205 |
Grade A, and why
storm-engine 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 22d 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 — 144 lines — stays where its author put it; the contents beside it link to each section on GitHub.
STORM Engine
Internal knowledge for the STORM plugin. Encodes the methodology ported from Stanford STORM (NAACL'24 / EMNLP'24) into a Claude-native pipeline. Loaded automatically by every /storm:* skill.
CRITICAL: Two-Stage Pipeline
The pipeline has two stages and four phases. Each phase is independently runnable and resumable — completed phases are loaded from the artifact directory, never re-run.
Stage 1 (Pre-writing) Stage 2 (Writing)
research ---------> outline ---------> write ---------> polish
(persona (draft + (per-section, (summary +
discovery, refine from cited, parallel) dedup)
simulated Q&A, research)
information table)
NEVER skip stage 1. An article generated from parametric memory alone is not a STORM article — it will hallucinate citations and miss the multi-perspective grounding that defines the method. If research/ is absent, run /storm:research first.
NEVER invent citations. Every inline [n] must map to an entry in sources.json collected during research. If a section has no supporting sources, write it without citations and flag the gap in the polish phase — do not fabricate a reference.
CRITICAL: Artifact Layout
All phases read from and write to a single per-topic directory:
<output_dir>/<slug>/
research/
personas.json # discovered personas (name + perspective + rationale)
conversations.jsonl # one record per (persona, turn): question, queries, snippets, answer
sources.json # deduplicated Information objects: {id, title, url, description, snippets}
outline.md # refined outline (markdown headings)
outline-draft.md # pre-research draft (kept for reference)
article.md # per-section draft with inline [n] citations
article-polished.md # final polished article
run-config.json # snapshot of run parameters
Stage-gating contract: a phase is considered complete when its primary artifact exists and is non-empty. Before running a phase, check its output artifact:
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.

storm-engine is a skill published in the GitHub repository FradSer/dotclaude (593 stars, last pushed 7d ago), licensed MIT. It adds 53 tokens to every session and 2,054 once invoked, about $0.0002 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 2026-09-24.
