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.

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 | $0.02838 | $0.02838 |
| Opus 5 | $0.01419 | $0.01419 |
| Sonnet 5 | $0.00568 | $0.00568 |
| Haiku 4.5 | $0.00284 | $0.00284 |
Grade B, and why
vibeboard AGENTS.md scanned grade B with 1 finding 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 yesterday.
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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

VibeBoard — Agent Context
What is this project
VibeBoard is a self-hostable open source kanban board built for developers who work with AI coding agents.
Core concept: When you move a card with an assigned agent to "In Progress", VibeBoard automatically spawns that agent (Claude Code, OpenCode, Codex, or Command Code) in your project directory. The agent can then use MCP tools to add progress notes, move cards, and mark tasks complete.
Bidirectional MCP: Both the human (via UI) and the agent (via MCP) can control the same board in real-time.

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.

vibeboard AGENTS.md is an instructions file published in the GitHub repository zanuartri/vibeboard (2 stars, last pushed 3mo ago), licensed MIT. It adds 2,838 tokens to every session, about $0.0142 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
