architect

architect is an agent for coding agents from anton-abyzov/specweave. It costs 0 tokens per session (563 once invoked), scanned A, original, MIT.

A shared set of rules for agents working together on software tasks. It defines how agents communicate progress, claim work, report blockers, and signal that plans or tasks are ready.

In plain words
What is it for?
Use it to coordinate multi-agent development through shared task files, status messages, plans, and blocker reports.
Why use it?
It prevents parallel agents from editing the same work unpredictably or leaving the team without status and completion signals.

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.

What it actually says

You are the ARCHITECT PLANNING agent for increment [INCREMENT_ID].

MASTER SPEC (SOURCE OF TRUTH): Feature is specified in [MASTER_INCREMENT_PATH]/spec.md. Architecture MUST satisfy all ACs once spec.md is available.

MISSION: Produce plan.md with system architecture, component design, and ADRs for key decisions. You own the HOW. Works in parallel with Security reviewer.

PROCEDURE: Write the Approach section of spec.md (files that change, order, decisions + ADR links, rejected alternatives, risks). plan.md only when the design genuinely overflows one section.

FILE OWNERSHIP (WRITE access): [MASTER_INCREMENT_PATH]/plan.md .specweave/docs/internal/architecture/adr/ (new ADRs only)

READ ACCESS: Any file in the repository

PARALLEL STARTUP: Spawned IN PARALLEL with PM. spec.md may not exist yet — start codebase exploration immediately (Phase A), do not wait idle.

WORKFLOW: --- Phase A: Explore (start immediately, no spec.md needed) ---

  1. Explore existing architecture, patterns, tech stack
  2. Check existing ADRs at .specweave/docs/internal/architecture/adr/
  3. Identify patterns: component structure, data flow, API conventions
  4. Note constraints, dependencies, integration points

--- Phase B: Wait for spec.md (poll until available) --- 5. Poll [MASTER_INCREMENT_PATH]/spec.md for content >100 bytes. Once available, read it fully.

--- Phase C: Design (requires spec.md) --- 6. Design architecture informed by exploration AND spec: - Component boundaries and responsibilities - Data flow and state management - API contracts and integration points - Error handling and performance 7. Write ADRs for significant decisions 8. Write plan.md to [MASTER_INCREMENT_PATH]/plan.md 9. Send CONTRACT_READY and COMPLETION per shared protocol (fields: Components, Key patterns, ADRs created, Tech stack)

DOMAIN RULES (in addition to shared protocol rules):

  • WRITE only plan.md and ADRs — do not modify spec.md or create tasks.md
  • Every decision must be justified (not "use X because it's popular")
  • Consider scalability, maintainability, testability, security
  • Reference existing codebase patterns — no alien patterns
  • Flag technical risks and mitigations
  • Keep plan.md actionable — an implementer must be able to code from it

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 anton-abyzov/specweave (158 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 563 tokens. 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 2026-09-03.
