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 | $0.00058 | $0.00378 |
| Opus 5.5 | $0.00023 | $0.00151 |
| Sonnet 5.5 | $0.00012 | $0.00076 |
| Haiku 4.5 | $0.00006 | $0.00038 |
Grade A, and why
agent-room 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.
What it actually says
Agent Room (single room per project)
One shared thread on the production server for this repo. Room code = shared secret.

Tools
| Tool | When |
|---|---|
create_room |
Start session; share code with teammate |
join_room |
User gives a 6-char code |
send_message |
Post question, answer, or status |
read_messages |
Catch up before shared edits |
wait_for_messages |
Waiting for reply (~25s, once) |
Workflow
- Person A:
create_room→ share code - Person B:
join_room({ code }) - Coordinate with
send_message/read_messages - Hooks + transcript update on new messages
If MCP missing
Direct user to docs/INSTALL-IN-PROJECT.md in https://github.com/umbecanessa/agent-room-mcp
Guidelines
- Same git repo required for both sides
- Before editing shared/core files:
read_messages - When user mentions teammate or transcript: read and reply via
send_message - Tell user to open
.cursor/agent-room-transcript.mdto read chat themselves - Do not poll
read_messagesin a loop — usewait_for_messagesonce
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.

agent-room is a skill published in the GitHub repository umbecanessa/agent-room-mcp (0 stars, last pushed 4mo ago), licensed MIT. It adds 58 tokens to every session and 378 once invoked, about $0.0002 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 2026-08-31.

story-readiness
Checks whether a story is ready to implement: clear acceptance criteria, no open questions, valid ADR and dependencies. Use when the user asks if a story, or the sprint's stories, are ready to start or build.
workthreads
SpecStory Workthreads - a weekly work-thread rollup across a team's repos from SpecStory coding histories (any agent - Claude Code, Codex, Cursor, Gemini, and more). It groups the window's sessions into threads of work per project and labels each new / open / recently closed, so a lead sees what shipped, what is still…
