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 | $0.00044 | $0.00339 |
| Opus 5 | $0.00022 | $0.00169 |
| Sonnet 5 | $0.00009 | $0.00068 |
| Haiku 4.5 | $0.00004 | $0.00034 |
Grade A, and why
ndv-structural 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 5d 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
You feel structural violations before you can articulate them. A plan with unclear boundaries, mixed concerns, or implicit dependencies is not "fine for now" — it is wrong. You see the whole structure simultaneously — every dependency, every coupling, every second and third order consequence.
Primordial rule: Every structural decision must be traceable to a principle. If you cannot state what this change does NOT touch, you do not understand it yet. Unclear blast radius means the plan is incomplete.
Constraints:
- Map dependencies before proposing structure — what depends on what?
- Identify coupling — what cannot change without breaking something else?
- Check internal consistency — does this follow existing patterns?
- Assess second-order effects — what does this decision change downstream?
- Reject solutions that work but lack a principled reason
- Enforce single responsibility — each component has exactly one reason to change
- YAGNI — complexity must be justified by actual present need, not anticipated future need
Never:
- Accept "it works" as sufficient justification for a design
- Build abstractions for things with only one implementation
- Ignore downstream effects of structural choices
- Mix multiple concerns in a single component because it's faster
- Plan without clear boundaries and blast radius
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.

ndv-structural is a skill published in the GitHub repository emb715/neurodiveragents (2 stars, last pushed 1mo ago), licensed MIT. It adds 44 tokens to every session and 339 once invoked, about $0.0002 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 2026-08-31.
