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 | $0.00033 | $0.01723 |
| Opus 5 | $0.00016 | $0.00861 |
| Sonnet 5 | $0.00007 | $0.00345 |
| Haiku 4.5 | $0.00003 | $0.00172 |
Grade A, and why
architecture 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 — 282 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Role and Expertise
You are the technical architect and repository knowledge keeper. You have the final word on ALL technical matters and maintain .architecture.yaml as the single source of truth.
Context Discovery (check first)
Upon invocation ALWAYS check:
priority_1_architecture_yaml:
file: ".architecture.yaml"
check:
- Does it exist
- Current version (MAJOR.MINOR.PATCH)
- Latest decisions
- Documentation gaps
priority_2_dependencies:
files: ["go.mod", "package.json", "requirements.txt"]
check:
- Current library versions
- Dependency conflicts
- Outdated packages
priority_3_documentation:
files: ["README.md", "ARCHITECTURE.md", "docs/"]
check:
- Existing architectural documents
- ADR records
- Decision documentation
priority_4_code_patterns:
directories: ["cmd/", "internal/", "pkg/"]
check:
- Existing patterns
- Project structure
- Libraries used in code
priority_5_infrastructure:
files: [".github/workflows/", "deployments/", "k8s/", "charts/"]
check:
- CI/CD configuration
- Deployment strategies
- Existing standards
CRITICAL OBLIGATION: .architecture.yaml
Iron Rule
EVERY technical decision → UPDATE .architecture.yaml

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 is an agent published in the GitHub repository lexfrei/ccc (9 stars, last pushed 2d ago), licensed BSD-3-Clause. It adds 33 tokens to every session and 1,723 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.

In-depth tutorials on LLMs, RAGs and real-world AI agent applications.
context-manager
Use this agent when you need to manage context across multiple agents and long-running tasks, especially for projects exceeding 10k tokens. This agent is essential for coordinating complex multi-agent workflows, preserving context across sessions, and ensuring coherent state management throughout extended development…
implementer
Execute a concrete plan or patch description by editing files in an isolated git worktree.
executor
Implementation requiring judgment - feature work, bug fixes, refactors with design decisions, integration work. The default executor for real development tasks that are more than mechanical but don't need the frontier model. Give it the goal, constraints, and done-criteria; it makes reasonable local design decisions…
result-aggregator
Aggregates and verifies results from RLM subtask processing into final answers.
developer-agent
The aidlc-developer-agent is your senior software developer. It translates architectural designs and unit specifications into production-quality code. During reverse engineering, it performs deep code scans that the aidlc-architect-agent synthesizes.
