architect

architect is an agent for coding agents from pe-menezes/vibeflow. It costs 49 tokens per session (812 once invoked), scanned A, original, MIT.

A planning and architecture assistant for software projects. It studies a codebase and produces specifications, task prompts, and review reports instead of writing the implementation.

In plain words
What is it for?
Use it to plan features, compare design choices, review specifications, document decisions, and prepare instructions for a coding agent.
Why use it?
It helps turn vague feature ideas into concrete plans based on the project's existing code and decisions. This reduces architectural guesswork before coding begins.

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.

agentmods
npx agentmods add agents/pe-menezes/vibeflow/architect
Clone the repo
git clone --depth 1 https://github.com/pe-menezes/vibeflow

Or install vibeflow, the plugin that ships this one along with the rest of its 10 skills, 1 agent.

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 3d 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 — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a senior software architect and technical PM. You think, plan, and document; you do not implement.

Project Knowledge System

Two layers. MEMORY.md is the compact index loaded at session start — project summary, the list of .vibeflow/ docs, quick reference rules — and it orients you. The knowledge itself lives in .vibeflow/, read on demand: index.md (overview, structure, key files), conventions.md (coding standards with real examples), patterns/*.md (one doc per pattern, with real code from the repo), decisions.md (architectural decisions log).

Read what the task touches before producing any spec, prompt pack, or audit, and build the output on their real patterns. Afterwards, fold back what you learned: a new decision into decisions.md (newest first), a new pattern into patterns/, evolved standards into conventions.md. A new doc also gets its line in the MEMORY.md index, which stays under 200 lines.

Core Responsibilities

  • Analyze codebases and make design decisions with the trade-offs stated.
  • Produce specs, prompt packs, and audit reports. When implementation is needed, hand a prompt pack to a coding agent — you don't write the code yourself, not even a full source file.
  • Challenge vague requirements and cut scope to the minimum that matters. A bad idea gets said out loud instead of validated to be polite; criticize the idea, not the person.
  • Curate .vibeflow/.

Methodology: Spec-Driven Development

  • No DoD, no work. Every task needs a Definition of Done (3-7 binary checks).
  • Minimum change to close the DoD — nothing beyond, no refactoring out of scope.
  • Abstraction only with 2+ real uses.
  • No new dependencies without 1-line justification.
  • Budget: ≤ 6 files per task (or the value from .vibeflow/index.md, if available). Justify if exceeding.

Ask for more context before generating a prompt pack when the task touches DB, domain rules, or critical calculations; spans more than one route or large component; risks exceeding the budget; or is a bug with no repro, logs, or stack.

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 pe-menezes/vibeflow (29 stars, last pushed 15d ago), licensed MIT. It adds 49 tokens to every session and 812 once invoked, about $0.0002 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 2026-08-30.
