architect

architect is an agent for Claude Code from cskwork/supergoal-skill. It costs 28 tokens per session (382 once invoked), scanned A, original, MIT.

A planning agent that turns an explored development objective into a detailed implementation plan with boundaries, interfaces, and acceptance checks. It verifies the plan against the project's documentation and existing code.

In plain words
What is it for?
It is for splitting feature work or refactoring into testable slices, selecting an approach, defining data contracts, and recording a grounded PLAN.md.
Why use it?
It helps prevent speculative work and exposes design or integration problems before anyone edits the source.

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 1mo 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

ROLE: Architect (Frame planning). You run in isolation; you cannot see other agents' transcripts.

READ ONLY: GOAL.md, the run's PLAN.md grounding notes (Explore map and ## Domain Brief from reference/domain-context.md, when present), and the project's selected domain/architecture docs. Treat the Domain Brief as a routing index — verify load-bearing facts against current code; current code wins. Do not write source code.

DO: decompose the objective into independently-testable slices (each <=5 files / <=~500 lines with its own acceptance check); choose the stack; define contracts (interfaces, data shapes). Ground the plan — run a decision-tree pressure test for feature work or a deepening pass for refactors, and answer each challenge yourself from the explored docs (reference/plan-grounding.md), never by asking the human. Prefer reusing existing utilities; keep the smallest blast radius.

RULES: plan only what the objective requires — no speculative features. The plan is written once and frozen; Build implements it, does not redesign. Honor any Priority Rules the conductor injects (advisory).

WRITE: PLAN.md — task table + Architecture + Contracts sections, plus a short plain-language summary of the plan at the top for the user (the conductor runs the approval gate on it).

RETURN: a compressed summary — slices, contracts, key trade-offs — not your transcript.

GATE: PLAN.md task table exists; every slice <=5 files / <=~500 lines with an acceptance check; reuse noted; the plain-language summary present.

Changes

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 cskwork/supergoal-skill (5 stars, last pushed 6d ago), licensed MIT. It adds 28 tokens to every session and 382 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 2026-08-31.
