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.

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 | $0.00033 | $0.01230 |
| Opus 5 | $0.00016 | $0.00615 |
| Sonnet 5 | $0.00007 | $0.00246 |
| Haiku 4.5 | $0.00003 | $0.00123 |
Grade A, and why
f1-test-drive 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 — 185 lines — stays where its author put it; the contents beside it link to each section on GitHub.
F1 Test Drive
Run comprehensive F1 test drives that validate the full pipeline:
- Issue-tracker behavior
- EdgeWorker execution flow
- Activity rendering/output quality
Mission
Execute test drives that verify:
- Issue-tracker correctness
- EdgeWorker worktree/session behavior
- Activity output visibility and formatting
Test Drive Protocol
Phase 1: Setup
-
Create a fresh test repository (if needed):
cd apps/f1 ./f1 init-test-repo --path /tmp/f1-test-drive-<timestamp> -
Start F1 server:
CYRUS_PORT=3600 CYRUS_REPO_PATH=/tmp/f1-test-drive-<timestamp> bun run apps/f1/server.ts & -
Verify server health:
CYRUS_PORT=3600 ./f1 ping CYRUS_PORT=3600 ./f1 status
Phase 2: Issue-Tracker Verification
-
Create test issue:
CYRUS_PORT=3600 ./f1 create-issue \ --title "<issue title>" \ --description "<issue description>" -
Verify issue ID and issue creation response.
Phase 3: EdgeWorker Verification
-
Start agent session:
CYRUS_PORT=3600 ./f1 start-session --issue-id <issue-id> -
Monitor activities:
CYRUS_PORT=3600 ./f1 view-session --session-id <session-id> -
Verify:
- session started
- activities appear
- agent is processing issue
Phase 3.5: Slack Chat Session Verification (optional)
Use when validating the Slack → ChatSessionHandler → ClaudeRunner path. F1 exposes a test-only endpoint /cli/dispatch-chat that injects a synthetic app_mention event without going through Slack signature verification (SlackChatAdapter no-ops Slack API calls when slackBotToken is undefined).
- Dispatch a synthetic chat event:
The response contains aCYRUS_PORT=3600 ./f1 start-chat-session \ --channel C_TEST_CHAN \ --user U_TEST_USER \ --text "hello"threadKeyof the form<channel>:<ts>. Reuse the same--thread-tsto address the same chat thread on subsequent dispatches.
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.
- 9d ago First seen · 185 lines · 33 tokens per session scan A 3b1a7e01ece3
f1-test-drive is a skill published in the GitHub repository cyrusagents/cyrus (798 stars, last pushed yesterday), licensed Apache-2.0. It adds 33 tokens to every session and 1,230 once invoked, about $0.0002 per session on Opus 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.

test-reporting
Run the Level 2 dummy agent integration test suite and produce a detailed HTML report with per-test input → outcome analysis.
develop-web-game
Use when Codex is building or iterating on a web game (HTML/JS) and needs a reliable development + testing loop: implement small changes, run a Playwright-based test script with short input bursts and intentional pauses, inspect screenshots/text, and review console errors with rendergametotext.
langbot-testing
Test LangBot WebUI and core product flows with an automated browser and backend logs. Use when validating the configured LangBot frontend, pipeline Debug Chat, model provider setup and test buttons, bot and knowledge-base UI flows, or troubleshooting failed LangBot end-to-end tests.
