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: 3 findings, 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 →

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 | $0.00073 | $0.02857 |
| Opus 5 | $0.00036 | $0.01429 |
| Sonnet 5 | $0.00015 | $0.00571 |
| Haiku 4.5 | $0.00007 | $0.00286 |
Grade A, and why
slack scanned grade A 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 11d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
### Priority 3: Direct Slack API via curl How it starts
The opening of the file, as written. The whole thing — 356 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Slack
Why? Stay on top of Slack without context-switching. Send messages, check channels, search conversations, and manage reactions -- all from your working session.
Quick Start
"Send a message to #general: standup starts in 5 min"
"Check my unread Slack messages"
"Search Slack for the deployment runbook"
Tool Detection
This skill adapts to available Slack tools. Detect at skill start:
Priority 1: Slack MCP Server
Check for MCP tools matching mcp__*slack* patterns (e.g., mcp__slack__send_message, mcp__slack__read_channel).
If Slack MCP tools are available, use them directly -- they handle authentication automatically.
Priority 2: Slack CLI (slack-cli or slackdump)
which slack 2>/dev/null || which slackdump 2>/dev/null
Priority 3: Direct Slack API via curl
Requires SLACK_BOT_TOKEN or SLACK_TOKEN environment variable:
[ -n "$SLACK_BOT_TOKEN" ] && echo "Bot token available" || echo "No bot token"
[ -n "$SLACK_TOKEN" ] && echo "User token available" || echo "No token"
If nothing is available, guide the user to set up a Slack integration (see Setup section).
Setup
Option A: Slack MCP Server (Recommended)
If the user's Claude/SwarmAI environment has a Slack MCP server configured, no additional setup is needed. MCP tools will be auto-discovered.
Option B: Slack Bot Token (API Access)
- Go to https://api.slack.com/apps and create a new app (or use existing)
- Under OAuth & Permissions, add scopes:
channels:read,channels:history-- Read public channelschat:write-- Send messagesreactions:read,reactions:write-- Manage reactionssearch:read-- Search messagesusers:read-- Look up user infoim:read,im:history-- Read DMsgroups:read,groups:history-- Read private channels (if needed)
- Install to workspace and copy the Bot User OAuth Token
- Set environment variable:
export SLACK_BOT_TOKEN=xoxb-your-token-here
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.
- 11d ago First seen · 356 lines · 73 tokens per session scan A 484104f2fc2f
slack is a skill published in the GitHub repository xg-gh-25/SwarmAI (44 stars, last pushed 4d ago), licensed MIT. It adds 73 tokens to every session and 2,857 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

recap
Read-only orientation — render a scannable table of what just happened so you can situate yourself. Modes: '/recap' (this session), '/recap arc' (the last product arc), '/recap commit' (the last commit), '/recap push' (the last push's commits — what I sent up), '/recap pull' (the last pull's changes — what came down…
digest
NOTE: this skill requires connected chat / email / project-tracker / docs MCPs, which are typically only present in Cowork — the Code variant exists for parity but most users will want the Cowork variant. Cross-tool rollup of what's pending, what shipped, and what's blocked across chat / email / project tracker /…
statusline
Install or remove the aria-knowledge status-line meter — a context-window progress bar plus the rolling 5-hour and 7-day plan-usage percentages, shown at the bottom of the Claude Code CLI. Use when the user says '/statusline', 'add a context meter', 'show context usage in the status line', 'show my 5-hour usage'…

Read and drive native desktop applications through the accessibility layer — list on-screen apps, snapshot one window as a numbered element tree, then click / type / set a value / scroll / drag / run a named action, by element index or by screen coordinates. Use for work in a desktop app rather than a web page. Full…
