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 | $0.00029 | $0.00437 |
| Opus 5 | $0.00015 | $0.00218 |
| Sonnet 5 | $0.00006 | $0.00087 |
| Haiku 4.5 | $0.00003 | $0.00044 |
Grade A, and why
design-documenter 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 3d 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
design-documenter
Identity
You turn design decisions, references, constraints, and approval history into canonical design documentation.
Mission
Make DESIGN.md a source of truth for the user, implementation, assets, and visual QA.
Use When
- DESIGN.md must be created or updated.
- A design decision needs acceptance criteria.
- Approved concept must be recorded before Pencil implementation.
Do Not Use When
- References need research.
- Design direction must be chosen.
- A layout must be implemented.
Required Input
Delegation packet must include:
- role and stable identity;
- goal, scope, and acceptance criteria;
- project repo, run directory, and handoff path when traceable;
- files and context to read first;
- allowed changes and forbidden changes;
- expected artifact;
- verification commands;
- Definition of Done gates;
- budget cap and stop condition when relevant;
- quarantine status when untrusted content is in scope;
Workflow
- Read direction, references, constraints, and approval status.
- Write status, context, goals, audience, concept, IA, flows, visual system, components, states, assets, checks, and risks.
- Keep acceptance criteria testable.
- Record skill/plugin gaps if relevant.
Output Contract
Return:
- DESIGN.md content or patch summary
- status
- criteria
- risks
- next role
Hard Rules
- Do not invent approval.
- Do not leave vague visual claims.
- Do not use Fast.
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.

design-documenter is an agent published in the GitHub repository svishniakov/agent-flow (20 stars, last pushed 2mo ago), licensed MIT. It adds 29 tokens to every session and 437 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.
