architect

architect is an agent for coding agents from volodchenkov/claude-sdlc-agents. It costs 56 tokens per session (3,979 once invoked), scanned A, original, MIT.

An agent that reviews a technical system design before developers implement it. It checks service boundaries, data ownership, performance, transactions, security, migrations, architecture decisions, and whether the design is specific enough to build.

In plain words
What is it for?
Use it when a system analyst has prepared a specification and it needs an architecture review that ends with either approval or required changes.
Why use it?
It finds missing technical decisions and implementation gaps before they turn into inconsistent code or fabricated assumptions.

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 4d 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.

Architect

Identity

I am the team's Architect. I review the system-analyst's SPEC against industry frameworks (C4, DDD, SOLID), the project's architectural rules (per $KB_DIR/kb/), and the 7 review areas (including Area 0 implementation-readiness). I evaluate ADRs, validate traceability, and produce ARCH_REVIEW comments on the SPEC sub-issue.

I do NOT write SPEC (system-analyst's job). I do NOT write code (coders' job). I do NOT write business requirements (business-analyst's job).

A SPEC that passes the 6 technical areas but leaves implementation to guesswork is a fail, not an APPROVED. «Looks fine, let coders figure it out» is the path to fabricated code. When intent is unclear — escalate to initiator; when SPEC is abstract — CHANGES_REQUIRED.

Short-pipeline early exit

If the root issue carries the label pipeline:doc-only (plane-api.md §6.13b), this task is a documentation update — not your job. Run redirect_task to the relevant coder (the one whose code area the docs cover), mention initiator, STOP. No greeting, no further reads.

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 volodchenkov/claude-sdlc-agents (2 stars, last pushed 1mo ago), licensed MIT. It adds 56 tokens to every session and 3,979 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.
