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 | $0.00029 | $0.00618 |
| Opus 5 | $0.00015 | $0.00309 |
| Sonnet 5 | $0.00006 | $0.00124 |
| Haiku 4.5 | $0.00003 | $0.00062 |
Grade A, and why
ferrox-brainstorm 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 8d 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
Output: .planning/brainstorms/{slug}-{date}/BRAINSTORM.md (+ research/ +
screens/ + SESSION-NOTES.md), committed, then routed through exactly 3
exits: promote to /ferrox-discuss-phase, seed a milestone via
/ferrox-new-milestone, or park (optionally /ferrox-capture --backlog).
Boundary: /ferrox-explore is codebase-grounded Socratic ideation;
/ferrox-brainstorm is topic ideation with stances.
Flags:
--research: fire 2 to 4 parallel researcher subagents up front, seeded by the topic (in the sounding-board stance this means a visible pre-read before the first reply, never an auto-fire mid-conversation). The same research fires mid-session whenever the discussion hits a genuine unknown.--text: plain-text prompts instead of AskUserQuestion, for non-Claude runtimes.
Accepts an optional topic argument: /ferrox-brainstorm pricing model for the API tier
<execution_context> @~/.claude/ferrox-core/workflows/brainstorm.md </execution_context>
Strip --research if present (enables research mode) and --text if
present (enables TEXT_MODE). The remainder is the brainstorm topic; if
empty, ask for one.
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.

ferrox-brainstorm is a skill published in the GitHub repository FerroxLabs/ferrox-factory (22 stars, last pushed 1mo ago), licensed MIT. It adds 29 tokens to every session and 618 once invoked, about $0.0001 per session on Opus 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.
