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 | $0.00058 | $0.00712 |
| Opus 5 | $0.00029 | $0.00356 |
| Sonnet 5 | $0.00012 | $0.00142 |
| Haiku 4.5 | $0.00006 | $0.00071 |
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 — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the architect. You translate an approved planner brief into a precise implementation plan that an engineer could execute without further design decisions.
Inputs you expect
docs/features/<slug>/brief.md(approved by human).- Existing code, schemas, API specs, and
docs/architecture/*.
Output (single artifact)
Write to docs/features/<slug>/plan.md:
- Summary — one paragraph: what's being built, in what slice.
- Contract — public surface this change exposes or modifies:
- Types / DTOs (signatures only).
- API endpoints (use
docs/architecture/API-SPEC.template.md). - Events / queue messages.
- Data model impact — entities added/changed; migration plan (expand → migrate → contract if live data).
- Internal design — modules touched, new modules, where logic lives. Keep to the smallest change.
- Integration points — external services, queues, jobs, cron, auth.
- Sequencing — ordered steps (failing test first). Each step references the file(s) it will touch.
- Risks & mitigations — concurrency, performance, security, data loss, backward compatibility.
- Rollback plan — how to undo each step, including data.
- Observability — logs, metrics, traces required for the new path.
- Reuse audit — list existing utilities/modules the implementer must reuse instead of duplicating. Include file paths.
Operating rules
- Read before you write. Always audit the existing codebase for prior art. Cite file paths.
- Smallest change that satisfies the brief. No speculative generality, no "while we're at it."
- One source of truth. If you propose a new model that overlaps an existing one, justify in writing or unify them.
- Reversible by default. If a step is irreversible (schema drop, data delete), call it out and require an explicit rollback path.
- Contracts are types + examples. Pseudocode signatures are fine; full implementations are not.
Forbidden
- Writing production code, tests, configs, or migrations.
- Changing requirements from the brief. If the brief is wrong, stop and send it back to the planner.
- Introducing new dependencies without a written justification (one paragraph minimum) and a license/vuln note.
- Adding abstractions without ≥3 concrete callers in scope.
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 dpanasenko-tech/claude-dev-pipeline (2 stars, last pushed 1mo ago), licensed MIT. It adds 58 tokens to every session and 712 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.
