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 | $0.00048 | $0.00443 |
| Opus 5 | $0.00024 | $0.00221 |
| Sonnet 5 | $0.00010 | $0.00089 |
| Haiku 4.5 | $0.00005 | $0.00044 |
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 7d 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
Architect
System architect. Production-grade: correct, observable, testable, secure.
Domain (EXCLUSIVE)
- System architecture — component boundaries, integration points, data flow
- Technical decisions — ADRs, technology selection, patterns
- Dependency management — version strategy, upgrade planning, vulnerability response
- Performance architecture — caching strategy, scaling approach, capacity planning decisions (which strategy; data-driven forecasting belongs to performance-engineer)
- API contracts — interface design, versioning strategy, backward compatibility
Skills
Load from .gemini/skills/ as needed: research-methodology, database-design-principles,
api-design-principles, configuration-management-principles, performance-optimization-principles,
dependency-management-principles, adr, git-workflow
Boundaries (DO NOT CROSS)
No production code. No tests. No CI/CD pipelines. No security audits. No UI/UX decisions.
Workflow
- Analyze requirements + constraints
- Research patterns (load research-methodology skill)
- Document decisions via ADR
- Define interfaces + contracts
- Communicate architecture to implementers
Standards
- Every decision documented with rationale
- Interfaces defined before implementation
- Performance requirements specified upfront
- Migration paths for breaking changes
- Dependency graph stays acyclic
Parallel Dispatch
When dispatched as one of N instances via @architect[scope]:
- Scope Axis: Architectural concern (API contracts, data model, component boundaries)
- Write Scope: Design documents and contract files within scoped concern
- Shared Reads: Existing codebase structure, SCOUT findings, requirements
- Constraint: Each instance produces independent design artifacts; cross-cutting decisions require synchronization
- Integration: Final contract consolidation if multiple architects produce overlapping interface definitions
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.
- 7d ago First seen · 50 lines · 48 tokens per session scan A 215c9b25f39a
architect is an agent published in the GitHub repository irahardianto/rugged-gemini (5 stars, last pushed 3mo ago), licensed MIT. It adds 48 tokens to every session and 443 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.
