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 | $0.00050 | $0.00300 |
| Opus 5 | $0.00025 | $0.00150 |
| Sonnet 5 | $0.00010 | $0.00060 |
| Haiku 4.5 | $0.00005 | $0.00030 |
Grade A, and why
architecture-docs 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.
What it actually says
Architecture Docs
Core Workflow
- Identify the audience, system boundary, source of truth, and decision the doc supports.
- Read the relevant code, configs, diagrams, existing docs, and tests before describing architecture.
- Document structure, responsibilities, data flow, integration points, dependencies, constraints, and operational assumptions.
- For decisions, capture context, options considered, tradeoffs, decision, consequences, and review triggers.
- Separate current architecture from planned architecture.
- Include validation notes and open questions.
Safety Rules
- Do not invent architecture, dependencies, guarantees, or operational behavior.
- Do not expose sensitive infrastructure, secrets, private endpoints, or threat details in public docs.
- Mark inferred architecture clearly when source evidence is incomplete.
Deliverable Shape
For architecture docs, provide:
- Scope and audience
- System overview
- Components and responsibilities
- Data or control flow
- Key decisions and tradeoffs
- Constraints and risks
- Validation notes
- Open questions
References
- Read

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.

architecture-docs is a skill published in the GitHub repository jeremylongworth-source/AgentSkills (1 stars, last pushed 5d ago), licensed MIT. It adds 50 tokens to every session and 300 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.

issue-authoring
Draft or refine IDD-ready GitHub issues, roadmap issues, and sub-issues before the normal IDD execution loop begins. Use when a request is too large or ambiguous for one reviewable change, when work needs decomposition or dependency encoding, or when the user asks for issue drafting, roadmap planning, or…
idd-spec-audit
Repo-local, dogfood-only semantic audit of the IDD instruction corpus for leaked session context, cross-file contradictions, fresh-memory completability gaps, automation blockers, and restatement-discipline drift. Use only in the kurone-kito/idd-skill source repository, on request, to audit .github/instructions…
unity-yaml-format
Inspect, explain, diff, and carefully edit Unity text-serialized files such as .unity, .prefab, .asset, and related YAML-based project files. Use when mapping class IDs and fileIDs, tracing object references, reviewing merge conflicts, or making minimal safe edits to existing UnityYAML documents.
joedevflow
Development workflow. Use when building a feature, creating an MVP, refactoring code, fixing a bug, or any task that involves writing or changing implementation code.
authos-backend-integration
Secure backend APIs with AuthOS-issued JWTs and the AuthOS Node server adapter. Use when building an API that must verify AuthOS bearer tokens, enforce JWT claims, add Express middleware, validate JWKS keys, or create a backend-owned session after a browser OAuth callback.
authos-service-management
Manage AuthOS tenant services, OAuth client credentials, redirect URIs, device activation URIs, plans, API keys, SAML settings, and checkout. Use when creating or configuring applications inside an AuthOS organization.
