ghostlink: Instructions file for Codex

AGENTS.md

ghostlink AGENTS.md is an instructions file for Codex, OpenCode from bgorzelic/ghostlink. It costs 461 tokens per session, scanned A, original, ISC.

A set of AGENTS.md instructions for coordinating software work between a lead agent and specialized helper agents. It defines roles, file boundaries, handoffs, and required checks.

In plain words
What is it for?
Planning repository work, assigning scoped tasks, reviewing changes, and running tests, linting, type checks, and builds.
Why use it?
It gives a development team a shared operating model so agents do not overwrite unrelated files or skip verification.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions subagents; mentions Claude Code; mentions AGENTS.md.

This is bgorzelic/ghostlink's own configuration. It tells Codex and OpenCode how to work on ghostlink itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything ghostlink configures →

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

ghostlink 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.

How it starts

The opening of the file, as written. The whole thing — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Operating Model

GhostLink development runs as a structured agentic swarm with a single Orchestrator and scoped sub-agents.

  • Orchestrator: Primary Claude Code instance. Owns plan, milestones, and final verification.
  • Sub-agents: Spawned only when isolation or parallelism improves output. Each has a declared scope and must not modify files outside it.

Global Rules

Every agent (orchestrator or sub-agent) must:

  1. Operate only within the repo root
  2. Return structured outputs (diffs + command outputs + assumptions)
  3. Run verification after edits (npm test && npm run lint && npm run typecheck && npm run build)
  4. Avoid broad refactors unless explicitly requested
  5. Never introduce arbitrary command execution surfaces

Roles

Role Scope Responsibility
Orchestrator Entire repo Plan, scope, milestones, merge, verify
Protocol Engineer src/server.ts, src/index.ts, src/types/* Server factory, tool registration, transport
Toolsmith src/core/tools/*, src/core/utils/*, src/core/policy/* Tool implementation, deterministic output
Security Reviewer docs/SECURITY.md, src/core/policy/* Threat model, audit, hardening recommendations
Test Engineer tests/* Unit + golden tests per tool
Docs Engineer docs/*, root markdown files Schema docs, architecture, prompts

Full sub-agent prompt templates: docs/PROMPTS.md

Handoff Contract

Every sub-agent response must include:

  1. Unified diff or exact file contents
  2. Commands executed and their output
  3. Assumptions and risks identified
  4. Next actions (if blocked or incomplete)

Long-Term Vision Alignment

All agents must preserve forward-compatibility with:

  • Remote transport (Phase 2)
  • Memory integration (Phase 3)
  • Runtime orchestration (Phase 3)

Never hard-code decisions that block Phase 2 or Phase 3 expansion. GhostLink remains the capability plane. Orchestration lives elsewhere.

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.
