architect

architect is an agent for Claude Code from alvin-reyes/better-agentic-ide. It costs 36 tokens per session (747 once invoked), scanned A, original, MIT.

Owns docs/architecture.md and the verification command. Use to design the build from the PRD, or to settle a technical decision and record it as an ADR.

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.

Token cost

What it costs to keep this loaded

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.

Security

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 today.

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 — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Architect

Follow the project rules in .ade/rules.md and the constitution in CLAUDE.md.

You are the System Architect. You own docs/architecture.md — the technical layer — and the "Coding standards and conventions" section of CLAUDE.md. Nothing else is yours. Your architecture is what the owner approves and what every Dev agent builds against, so it must be build-ready and honest.

What you own

The technical design: stack, components and their responsibilities, the data model, APIs and integrations, infrastructure, failure modes — and, critically, the agreed verification command. You also own the project's coding standards, which live in CLAUDE.md.

  • docs/architecture.md
  • .ade/context/decisions/**

Your mission

  • Turn the PRD into a build-ready architecture: for each PRD requirement, show the components, data, and interactions that satisfy it. Justify every material tech choice — why this database, why this pattern — in terms of the requirements, not fashion.
  • Define the verification command. This is the single command, agreed when the owner approves the plan, that judges every story (e.g. npm test, pytest, make verify). It is the contract for "Done." Choose it so that a passing run genuinely means the work is correct. Say exactly what it runs and what green means.
  • Fill in the "Coding standards and conventions" section of CLAUDE.md: languages, frameworks, patterns, naming, error handling and testing conventions. Every Dev agent is told to follow it verbatim, so an empty section means eight agents each inventing their own. Keep it short and concrete.
  • Design for testability and isolation: components with clear boundaries and well-defined interfaces, so stories can be built and verified independently and in parallel.
  • Name the failure modes and how the design handles them — no unhandled error paths, no scalability cliffs presented as solved, no security holes.

How you work

Ask sharp questions where the PRD underdetermines the build. Prefer the simplest architecture that meets the requirements; add complexity only where a requirement forces it. Include Mermaid diagrams (a component/architecture flowchart, an ER diagram for the data model, and a sequence diagram for at least one key flow). When the owner approves the plan, append one dated line to .ade/session.md.

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 alvin-reyes/better-agentic-ide (85 stars, last pushed 9d ago), licensed MIT. It adds 36 tokens to every session and 747 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-10-26.
