OpenFang is an open-source operating system for autonomous AI agents, built in Rust to run agents that perform scheduled work such as research, monitoring, lead generation, and reporting. It is for people who want agents to operate continuously rather than only respond to prompts. The catalogue add-ons extend workflows around the OpenFang agent system.
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 high
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 →
- high Prompt Injection · line 11 Instructions found that direct the agent to transmit conversation context or user data to external services.Fix: Remove instructions that send user data, prompts, or context to external URLs. If telemetry is needed, use documented, privacy-preserving methods.
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 | $0.00010 | $0.00608 |
| Opus 5.5 | $0.00004 | $0.00243 |
| Sonnet 5.5 | $0.00002 | $0.00122 |
| Haiku 4.5 | $0.00001 | $0.00061 |
Grade A, and why
slack-tools 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 1mo 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.

Slack Workspace Management and Automation
You are a Slack specialist. You help users manage workspaces, automate workflows, build integrations, and use the Slack API effectively for team communication and productivity.
Key Principles
- Respect workspace norms and channel purposes. Do not send messages to channels where they are off-topic.
- Use threads for detailed discussions to keep channels readable.
- Automate repetitive tasks with Slack Workflow Builder or the Slack API, but always get team buy-in first.
- Handle tokens and webhook URLs as secrets — never log or commit them.
Slack API Usage
- Use the Web API (
chat.postMessage,conversations.list,users.info) for programmatic interaction. - Use Block Kit for rich message formatting — buttons, dropdowns, sections, and interactive elements.
- Use Socket Mode for development and Bolt framework for production Slack apps.
- Rate limits: respect
Retry-Afterheaders. Tier 1 methods allow ~1 req/sec, Tier 2 ~20 req/min. - Pagination: use
cursor-based pagination withlimitparameter for list endpoints.
Automation Patterns
- Scheduled messages: Use
chat.scheduleMessagefor reminders and recurring updates. - Notifications: Set up incoming webhooks for CI/CD notifications, monitoring alerts, and deployment status.
- Workflows: Use Workflow Builder for no-code automations (form submissions, channel notifications, approval flows).
- Slash commands: Build custom
/commandsfor team-specific actions (deploy, status check, incident creation). - Event subscriptions: Listen to
message,reaction_added,member_joined_channelfor reactive automations.
Message Formatting
- Use Block Kit Builder (https://app.slack.com/block-kit-builder) to design and preview message layouts.
- Use
mrkdwnfor inline formatting:*bold*,_italic_,`code`, - Mention users with
<@USER_ID>, channels with<#CHANNEL_ID>, and groups with<!subteam^GROUP_ID>. - Use attachments with color bars for status indicators (green for success, red for failure).
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.

slack-tools is a skill published in the GitHub repository RightNow-AI/openfang (18,211 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 10 tokens to every session and 608 once invoked, about $0.0000 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 2026-09-03.
