opencode-drewgent AGENTS.md

Repository instructions for opencode-drewgent, a template for building an AI-agent system. It covers agent roles, delegation, integrations, scheduled jobs, and a structured knowledge vault.

In plain words
What is it for?
Working on agent profiles, tool integrations, project folders, automation, task pipelines, and the P0–P6 vault structure.
Why use it?
They give an agent consistent rules for navigating and extending the template without breaking its organization or responsibilities.

Getting it into your 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

opencode-drewgent AGENTS.md 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.

opencode-drewgent — Agent Template Guide

This is a template — a starting point for your own personal AI agent system. Fork it, rename it, and make it yours.

Architecture Overview

opencode-drewgent provides a structured agent system built on opencode. It includes:

  • Subagent profiles — specialized agent roles (engineer, reviewer, analyst, etc.) with assigned models and tool permissions
  • Delegation patternstask() for same-model subtasks, gjc_delegate_* for isolated/parallel execution via GJC Coordinator MCP
  • Vault structure — P0-P6 Obsidian vault for rules, identity, memory, sensors, cortex, ego, and prefrontal
  • MCP integration — example config for local and remote MCP servers
  • Kanban pipeline — task decomposition with leverage scoring
  • Cron automation — example jobs for housekeeping, content, and monitoring

Structure Principles

.
├── agent/          ← Core .py package (NOT root-level .py files)
├── gateway/        ← Platform adapters
├── cron/           ← Scheduler
├── tools/          ← Tool implementations
├── skills/         ← Agent skills
├── projects/       ← External work (one subdir per project)
├── brain/          ← P0-P6 vault + @identity
├── state/          ← DBs, logs, sessions
├── config/         ← Settings, dotfiles
└── docs/           ← Documentation

Key rule: Root must stay lean. Agent code goes in agent/. External work goes in projects/. Flat root accumulation is tech debt — each file at root is a decision that needs a justification.

Subagent Profiles

See .opencode/agents/*.md for the full list. Key profiles:

Profile Model Role
implementer flash Code generation, file edits
reviewer pro Code review, quality gate
explorer flash Codebase discovery, research
planner max Task decomposition, planning
architect pro Architecture decisions
sre flash Infrastructure, monitoring

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.
