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: 23 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 | $0.00082 | $0.09305 |
| Opus 5 | $0.00041 | $0.04653 |
| Sonnet 5 | $0.00016 | $0.01861 |
| Haiku 4.5 | $0.00008 | $0.00931 |
Grade A, and why
slack-bot 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 7d 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.

Slack Bot
Send messages and rich content to Slack channels using Incoming Webhooks or the Slack Web API. Build formatted announcements, marketing reports, metrics dashboards, and community updates with Block Kit.
Prerequisites
Requires either SLACK_WEBHOOK_URL or SLACK_BOT_TOKEN set in .env, .env.local, or
~/.claude/.env.global.
source ~/.claude/.env.global 2>/dev/null
source .env 2>/dev/null
source .env.local 2>/dev/null
if [ -n "$SLACK_WEBHOOK_URL" ]; then
echo "SLACK_WEBHOOK_URL is set. Webhook mode available."
elif [ -n "$SLACK_BOT_TOKEN" ]; then
echo "SLACK_BOT_TOKEN is set. Web API mode available."
else
echo "Neither SLACK_WEBHOOK_URL nor SLACK_BOT_TOKEN is set."
echo "See the Setup Guide below to configure Slack credentials."
fi
If neither variable is set, instruct the user to follow the Setup Guide section below.
Setup Guide
Option A: Incoming Webhook (Simple)
Incoming Webhooks are the fastest way to post messages. They require no OAuth scopes and are scoped to a single channel.
- Go to https://api.slack.com/apps and click Create New App > From scratch.
- Name the app (e.g., "Marketing Bot") and select your workspace.
- In the left sidebar, click Incoming Webhooks and toggle it On.
- Click Add New Webhook to Workspace at the bottom.
- Select the channel to post to and click Allow.
- Copy the Webhook URL (starts with
https://hooks.slack.com/services/...). - Add it to your environment:
echo 'SLACK_WEBHOOK_URL=https://hooks.slack.com/services/T.../B.../xxxx' >> .env
Limitations: One webhook per channel. Cannot read messages, list channels, or reply to
threads programmatically (you must know the thread_ts from a prior API response).
Option B: Bot Token (Full Featured)
Bot tokens give access to the full Slack Web API: post to any channel the bot is in, reply to threads, list channels, upload files, and more.
- Go to https://api.slack.com/apps and click Create New App > From scratch.
- Name the app and select your workspace.
- In the left sidebar, click OAuth & Permissions.
- Under Bot Token Scopes, add these scopes:
chat:write- Post messageschat:write.public- Post to channels without joiningchannels:read- List public channelsfiles:write- Upload files (optional, for images/reports)reactions:write- Add emoji reactions (optional)
- Click Install to Workspace at the top and authorize.
- Copy the Bot User OAuth Token (starts with
xoxb-). - Add it to your environment:
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.
- 7d ago First seen · 1,247 lines · 82 tokens per session scan A b56758329568
slack-bot is a skill published in the GitHub repository OpenClaudia/openclaudia-skills (687 stars, last pushed 2d ago), licensed MIT. It adds 82 tokens to every session and 9,305 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 2026-09-03.
