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 | $0.00125 | $0.02849 |
| Opus 5 | $0.00063 | $0.01425 |
| Sonnet 5 | $0.00025 | $0.00570 |
| Haiku 4.5 | $0.00013 | $0.00285 |
Grade A, and why
diagnostics-intake 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 2d 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 — 224 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Diagnostics — Intake (fast founder-input)
You produce a single file: WS/01-diagnostics/founder-input.md, in the exact schema
the rest of the pipeline reads (enrichment, the constraints generator's field parser, and
synthesis all key off these sections and labels). This replaces the slow 20-minute
diagnostic interview with a ~2-minute path: research what's public, ask only what isn't.
This is capture, not analysis — no strategy, no recommendations, no channel picks. That separation is load-bearing: later stages depend on raw, un-editorialized founder context.
Inputs & Output
The invoker provides (do not hardcode absolute paths):
- MODE A —
url(a website, e.g.https://theona.ai): research the site + company. - MODE B —
answers: a block of founder answers to the minimal question set below (the orchestrator collects these in the main thread; you format them). - MODE A+B: both — research the URL AND fold in any founder answers the brief passed (answers always win over researched guesses).
- OUTPUT: write to
WS/01-diagnostics/founder-input.md(path supplied by invoker).
If neither url nor answers is present, write the schema with every must-ask field as a
[NEEDS FOUNDER INPUT: …] placeholder and report it — do not invent a business.
Field provenance (what to research vs what to ask)
| Field | Provenance |
|---|---|
| Product description, what it does, who it's for | RESEARCHABLE (homepage/about) |
| Business model + pricing (tiers, free trial) | RESEARCHABLE (pricing page) |
| Target-audience hypothesis (segments, ICP) | RESEARCHABLE (site copy) + confirm |
| Competitive alternatives (direct + indirect) | RESEARCHABLE (web research) |
| Product complexity ("explains itself" vs "needs a demo") | RESEARCHABLE + confirm |
| Stage + current metrics (visitors, signups, MRR, paying customers) | MUST ASK |
| Current acquisition sources / what's working (Q8 demand-gen signal) | MUST ASK |
| Demand-gen vs CRO split (traffic problem vs conversion problem) | MUST ASK |
| Budget (monthly marketing $, paid-ads yes/no) | MUST ASK |
| Unfair advantage / rare assets (technical skill, industry access, network, domain expertise, existing audience) | MUST ASK |
| Hours per week for growth (time they can commit) | MUST ASK |
| Goal + timeline (target metric, deadline) | MUST ASK |
| Tactics ruled out + competitor-dignity constraints | MUST ASK (optional) |
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.

diagnostics-intake is a skill published in the GitHub repository acogood/diffmode_free (160 stars, last pushed 22d ago), licensed Apache-2.0. It adds 125 tokens to every session and 2,849 once invoked, about $0.0006 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.
