fiber-ai-plugin AGENTS.md

fiber-ai-plugin AGENTS.md is an instructions file for Codex, OpenCode from fiber-ai/fiber-ai-plugin. It costs 2,193 tokens per session, scanned A, original, MIT.

Repository instructions for a plugin that adds workflow skills and specialist agent profiles to several AI coding tools. It explains the repository structure and rules for writing these skills and profiles.

In plain words
What is it for?
Use it when extending the plugin, authoring a workflow skill, or creating and maintaining specialist agent profiles for supported coding tools.
Why use it?
It gives coding agents the context and rules they need before changing the plugin, while pointing them to the main documentation when it is stored elsewhere.

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

fiber-ai-plugin 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 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.

AGENTS.md — fiber-ai-plugin

This repository ships Fiber AI as a first-class plugin for AI coding agents (Claude Code, Cursor, Codex, OpenCode, Copilot CLI, Gemini CLI, VS Code, Windsurf). If you are an agent inspecting this repo to fix something or extend it, read this file first.

What this repo contains

  • skills/ — per-workflow skills (Markdown). Each skill has a SKILL.md with YAML frontmatter (name, description, user-invocable, argument-hint). The description is what other agents match against to auto-load the skill, so it must contain realistic user trigger phrases.
  • agents/ — persona subagent files (Claude Code / Cursor / OpenCode compatible). Flat .md files; each is a full subagent system prompt with YAML frontmatter. See "Persona authoring rules" below. Current personas: ai-recruiter, ai-sdr, gtm-strategist, signal-scout, data-quality-auditor, product-engineer, fiber-sde.
  • cursor/agents/ — Cursor-compatible copies of the persona files (plain cp from agents/).
  • .opencode/agents/ — OpenCode-compatible copies of the persona files (cp + frontmatter swap: name/tools/skills/mcpServers/color removed, mode: subagent added).
  • .codex/agents/ — Codex CLI TOML translations of the persona files. Generated from agents/*.md via a small bash script; the developer instructions body is copied verbatim, not re-authored.
  • .mcp.json, cursor/mcp.json, vscode/mcp.json, gemini-extension.json — MCP server configuration for each supported environment. All three Fiber MCP endpoints should appear in every config:
    • https://mcp.fiber.ai/mcp/v2 — direct tools for the top ~10 priority operations, API-key auth.
    • https://mcp.fiber.ai/mcp/v3 — direct tools for every public operation with compact descriptions, OAuth (SSO) auth.
    • https://mcp.fiber.ai/mcp — 5 meta-tools (search_endpoints, list_tag_packs, list_all_endpoints, get_endpoint_details_full, call_operation) over every public operation, API-key auth (same shape as V2).
  • .claude-plugin/, .cursor-plugin/ — manifest files for the Claude Code and Cursor plugin formats. Both register agents/ alongside skills/.
  • cursor/rules/, windsurf/rules/ — rule files surfaced to the agent inside those IDEs.
  • hooks/ — Claude Code lifecycle hooks (hooks/hooks.json). Do not also set "hooks" in .claude-plugin/plugin.json; Claude Code auto-discovers hooks/hooks.json and a duplicate manifest entry loads hooks twice.
  • .opencode/INSTALL.md — fetch-and-follow install instructions for OpenCode.

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.
