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 | $0.00068 | $0.01184 |
| Opus 5 | $0.00034 | $0.00592 |
| Sonnet 5 | $0.00014 | $0.00237 |
| Haiku 4.5 | $0.00007 | $0.00118 |
Grade A, and why
rd-specification 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.
How it starts
The opening of the file, as written. The whole thing — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.
rd-specification
Support standards and specification work with clause-level rigor, evidence discipline, and normative wording control.
Deliverables
- Standards/specification draft outline or clause draft
- Clause-level issue and revision table
- Normative wording replacement proposals
- Terminology and reference consistency checklist
- Open issues requiring expert, legal, standards-body, or domain-owner confirmation
Execution Steps
1. Scope and Authority Confirmation
- Identify the standard type: national, industry, enterprise, internal guideline, or project specification
- Confirm the document status: draft, review draft, approval draft, published baseline, or revision
- Identify the target audience and expected authority of the document
- Confirm whether the work is drafting, revision, clause analysis, comparison, or gap analysis
- Identify the governing drafting rules and normative vocabulary for the target standards body or organization; do not assume one universal shall/should convention
- Confirm jurisdiction, edition, effective date, supersession status, and applicability boundary when they affect authority
Completion criterion: document type, status, authority, task mode, drafting rules, jurisdiction, edition, and applicability are either verified or explicitly bounded.
2. Target and Authority Hierarchy
Treat the current target text and clause numbering as the object under change, not as proof of its own authority. Establish governing authority in this order:
- Binding laws, regulations, standards, official specifications, or formally delegated authority
- Applicable referenced standards and normative documents
- Approved upstream project documents or organizational rules within their delegated scope
- Expert judgment, clearly labeled as judgment rather than fact
When evidence is missing, mark "insufficient evidence, requires human verification" instead of inventing a basis.
Completion criterion: every material clause or revision proposal identifies its target anchor and governing authority level; conflicts between the target and a higher authority, and unavailable authority, remain visible as verification gaps.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

rd-specification is a skill published in the GitHub repository alieismy/codex-three-layer-delivery (2 stars, last pushed today), licensed MIT. It adds 68 tokens to every session and 1,184 once invoked, about $0.0003 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.
