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 | $0.00045 | $0.00758 |
| Opus 5.5 | $0.00018 | $0.00303 |
| Sonnet 5.5 | $0.00009 | $0.00152 |
| Haiku 4.5 | $0.00005 | $0.00076 |
Grade A, and why
slack-cli scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
compatibility: Requires official Slack CLI from docs.slack.dev (not rockymadden/slack-cli), plus curl How it starts
The opening of the file, as written. The whole thing — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Slack CLI (Official Slack Developer CLI)
Use the official Slack Developer CLI documented at docs.slack.dev/tools/slack-cli/.
This CLI is for Slack app development and platform management.
It is not the community chat automation CLI (slack chat send, etc.).
When to Use
- Create or initialize a Slack app project
- Log in/out and manage authorized teams for app development
- Run and deploy Slack apps
- Manage manifests, env vars, functions, and triggers
- Run diagnostics with
slack doctor
Setup
If slack is not found, or slack --help does not mention app development, see references/INSTALLATION.md.
Some machines already have another slack binary (e.g., Slack desktop). In that case, the official CLI can be installed as slack-dev.
Use this detection pattern first:
if slack --help 2>/dev/null | grep -q "create, run, and deploy Slack apps"; then
SLACK_CMD=slack
elif slack-dev --help 2>/dev/null | grep -q "create, run, and deploy Slack apps"; then
SLACK_CMD=slack-dev
else
echo "Official Slack CLI not found"
fi
Authorize after install:
"$SLACK_CMD" login
"$SLACK_CMD" list
Core Commands
"$SLACK_CMD" version
"$SLACK_CMD" doctor
"$SLACK_CMD" login
"$SLACK_CMD" logout
"$SLACK_CMD" list
Project Lifecycle
# Create a new project
"$SLACK_CMD" create
# Initialize an existing project directory
"$SLACK_CMD" init
# Run app locally
"$SLACK_CMD" run
# Deploy app
"$SLACK_CMD" deploy
App and Platform Management
"$SLACK_CMD" manifest info
"$SLACK_CMD" manifest validate

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-cli is a skill published in the GitHub repository ulises-jeremias/agent-toolkit (19 stars, last pushed 2d ago), licensed MIT. It adds 45 tokens to every session and 758 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-04.
