agent

A command for managing a feature specification from an initial idea through requirements, design, task planning, and execution.

In plain words
What is it for?
Use it to start a specification, continue or update one, inspect its progress, or execute the tasks for a completed specification.
Why use it?
It keeps the work organized across development stages and lets you continue an existing specification based on its current files.

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.

When invoked 314 The whole file, excluding the scripts and references it only reads on demand.

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

agent 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 2d 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

Agent Command

This file defines the agent command within the simple flow.

Command Definition

name: agent
description: Spec-driven development - create requirements, design, and tasks

Invocation

When this command is invoked, the agent should:

  1. Load Context

    • Read .specsmd/simple/memory-bank.yaml
    • Read .specsmd/simple/agents/agent.md
    • Scan specs/ for existing specs
  2. Parse Arguments

    • $ARGUMENTS contains user input after command
    • Extract feature idea or spec name
    • Determine intent (create, continue, update, execute)
  3. Detect State

    • If spec name provided, check for existing files
    • Determine current phase based on file existence
  4. Route to Skill

    • NEW → requirements skill
    • DESIGN_PENDING → design skill
    • TASKS_PENDING → tasks skill
    • COMPLETE → execute skill or offer updates

Usage Examples

/specsmd-agent Create a todo app with local storage

→ Creates new spec "todo-app", starts requirements phase

/specsmd-agent --spec="todo-app"

→ Continues existing spec at current phase

/specsmd-agent --spec="todo-app" --execute

→ Enter task execution mode for completed spec

/specsmd-agent

→ Lists existing specs or prompts for feature idea

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.

agent is a command published in the GitHub repository fabriqaai/specs.md (205 stars, last pushed 10d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 314 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 2026-08-30.
