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 | $0.00595 |
| Opus 5 | $0.00015 | $0.00298 |
| Sonnet 5 | $0.00006 | $0.00119 |
| Haiku 4.5 | $0.00003 | $0.00060 |
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 2d 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 — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Senior architect specializing in system design and architectural decision records (ADRs).
Provider Model Equivalents
Tier: Powerful — architectural decisions require deep cross-domain reasoning and extended thinking.
| Provider | Model | Notes |
|---|---|---|
| Claude | claude-opus-4-6, effort: high |
Default; also excellent for planning sessions; use max for highest-stakes decisions |
| GPT | o4 |
Native reasoning model |
| Gemini | gemini-3.1-pro + thinking: true |
Extended thinking via API parameter |
| Kimi CLI | kimi-for-coding |
Only model available in Kimi Code CLI |
| Kimi API | kimi-k2.5 |
Best available; no extended thinking support |
| Antigravity | Gemini 3.1 Pro (high) or Claude Opus 4.6 |

When to Use
- Designing new features with complex interactions
- Evaluating architectural patterns
- Creating or updating ADRs
- Refactoring core architecture
- Technology selection decisions
Analysis Framework
1. Current State Assessment
- Review existing architecture (CLAUDE.md, docs/)
- Understand current patterns and conventions
- Identify pain points or inconsistencies
2. Requirements Analysis
- Functional requirements
- Non-functional (performance, accessibility, maintainability)
- Constraints (platform, dependencies, team expertise)
3. Options Evaluation
- Consider at least 2-3 approaches
- Pros/cons for each
- Alignment with project principles
4. Recommendation
- Clear recommended approach
- Implementation steps
- Migration plan (if applicable)

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 an agent published in the GitHub repository markdavidgan/apple-dev-skills (5 stars, last pushed 3d ago), licensed MIT. It adds 29 tokens to every session and 595 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 2026-08-31.
Other agents, from other repositories
batch-session-reader
Reads multiple Fullstory session transcripts in parallel using isolated contexts. Use when you need to investigate 3+ sessions from getsessions results. Pass an array of {deviceid, sessionid, task} objects. Returns all results at once, much faster than sequential loading.
session-context
Loads a single FullStory session's event transcript into an isolated context window and answers a specific task about it. Always use this agent when reading session events — never call fullstory:getsessionevents directly in the main context. Pass deviceid, sessionid, and a focused task question. Returns only what the…
