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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00085 | $0.01641 |
| Opus 5.5 | $0.00034 | $0.00656 |
| Sonnet 5.5 | $0.00017 | $0.00328 |
| Haiku 4.5 | $0.00009 | $0.00164 |
Grade A, and why
using-agent-relay 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 9d 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 — 163 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Role Check
- you were spawned into a Relay team
- the prompt gave you a workspace key or Relay identity
- you can call
set_workspace_key,create_workspace, orregister_agent - you need to ACK, report status, DM peers, post to channels, or check inbox
Current MCP Tool Names
The current Agent Relay MCP server registers flat tool names. Use the final tool name exactly as listed here.
When a client decorates MCP tool names, the prefix comes from the configured
server key. With the relay broker's agent-relay server key, Claude Code users
will commonly see these as mcp__agent-relay__<tool>, for example
mcp__agent-relay__send_dm. Codex and opencode users see the bare canonical
names, such as send_dm.
Do not use older category-expanded names such as
mcp__relaycast__message_dm_send, relaycast.message.dm.send, or
message.post.

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.

using-agent-relay is a skill published in the GitHub repository AgentWorkforce/relay (888 stars, last pushed today), licensed Apache-2.0. It adds 85 tokens to every session and 1,641 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

goal-conductor
Own a goal too large for one session ('clear the flaky-test backlog', 'push N PRs green') end to end via the work ledger — decompose into items, one session per item, read worker status as data, verify claims with the acceptance evaluator, decide each round until done. Use when handed such a goal.
