What is opencode-hive AGENTS.md?

Project instructions for OpenCode Hive, a template that installs a multi-agent setup into other coding projects.

Use them when installing or configuring OpenCode Hive, selecting models for different jobs, or adapting its agents and rules to a project.

They define how to choose available models and identify the target project's technology before configuring the setup.

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.

Model	Per session	Once invoked
Fable 5.1	$0.01233	$0.01233
Opus 5.5	$0.00493	$0.00493
Sonnet 5.5	$0.00247	$0.00247
Haiku 4.5	$0.00123	$0.00123

Security

Grade A, and why

opencode-hive 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 2mo 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 Hive

A multi-agent architecture for OpenCode. This is a template -- not a project to develop, but a system to install into other projects.

Directory Structure

global/ -- Files to install at ~/.config/opencode/ (agents, tools, scripts, rules, skills)
project/ -- Files to install at .opencode/ in the target project
examples/ -- Optional specialist agents to pick based on project stack
docs/ -- Guides for model selection, adding specialists, architecture

AI Setup Instructions

When a user asks you to "set this up", "install this", or "configure my project":

Step 1: Discover Available Models

Run opencode models and present the output. Ask the user:

"Which of these providers are subscription/free (no per-token cost)?"
"Which provider/model do you want for code generation?"

Categorize into three tiers:

SUB: Subscription models -- for routing, planning, review, wiki
MID: Pay-per-token coding models -- for implementation specialists
PREMIUM: Frontier models -- never assign as default, manual override only

Step 2: Detect Target Project Stack

Ask the user for the target project path, then scan it:

ls <target>/*.py <target>/*.ts <target>/*.go <target>/*.rs 2>/dev/null | head -20
ls <target>/package.json <target>/pyproject.toml <target>/go.mod <target>/Cargo.toml 2>/dev/null
ls <target>/Dockerfile <target>/docker-compose* 2>/dev/null

Step 3: Install Global Files

Copy each global/ folder to ~/.config/opencode/:

agents/*.md, tools/*.ts, scripts/*, skills/*/, rules/*.md
Merge opencode.json — don't overwrite existing MCP, LSP, or plugin config

Ask before overwriting any existing files.

Step 4: Replace Model Placeholders

In all copied files, replace these four placeholders with real model IDs:

YOUR_ROUTING_MODEL -> fast, reliable model for routing
YOUR_ANALYSIS_MODEL -> strong model for planning and review
YOUR_FAST_MODEL -> inexpensive model for titles and summaries
YOUR_CODE_MODEL -> strongest available code-generation model

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.
