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 | $0.00039 | $0.00525 |
| Opus 5 | $0.00019 | $0.00262 |
| Sonnet 5 | $0.00008 | $0.00105 |
| Haiku 4.5 | $0.00004 | $0.00052 |
Grade A, and why
architect 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 today.
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 — 31 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Architect
Follow the governing instructions and the user's requirements for communication, code style, authorization, and delegation. This skill supplies task-specific guidance, not permission to expand the task. Its workflow and output fields describe internal checks and relevant content, not a mandatory response layout or a progress report. When used within broader authorized work, continue that work through completion rather than stopping to deliver this skill's intermediate result.
Produce the smallest design that makes the requested implementation predictable.
Ground the decision
Read the relevant entry points, types, tests, and one nearby precedent. Establish the user-visible outcome, current invariants, compatibility requirements, and decisions that actually remain open. Separate evidence from assumptions. Resolve routine reversible choices without asking the user.
Shape the design
Identify responsibilities, public signatures, state ownership, data flow, and dependency direction only where they affect the requested behavior. Prefer existing boundaries and concrete code over speculative layers or services. Make invalid states difficult to represent and validate external inputs at their boundaries.
Start from a direct implementation within the existing structure. Introduce another boundary only when current behavior, an established contract, or a concrete risk requires it. One implementation does not by itself justify an interface and factory, although a required framework or safety boundary may. Do not invent future consumers to justify a general design. Keep any rationale internal unless the requested deliverable calls for it.
When the actual task involves distributed state, domain boundaries, resilience, recovery, or a critical external dependency, consult the relevant paragraphs in design considerations. Do not apply all advanced considerations to every feature. Do not invent capacity plans, emergency procedures, migration stages, or organizational ownership for a local change.
What ships with it
2 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.

architect is a skill published in the GitHub repository dayfinggg/openai-codex-agent-skills (4 stars, last pushed today), licensed MIT. It adds 39 tokens to every session and 525 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.
