What is slack-search?

A guide for searching Slack, the workplace messaging platform, to find messages, files, channels, and people.

It is for choosing search tools, starting with broad searches, and narrowing results with keywords, channels, people, or dates.

It helps locate useful conversations and information without manually checking every channel or direct message.

Token cost

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	$0.00020	$0.00965
Opus 5	$0.00010	$0.00483
Sonnet 5	$0.00004	$0.00193

Security

Grade A, and why

slack-search 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.

Slack Search

This skill provides guidance for effectively searching Slack to find messages, files, and information.

When to Use

Apply this skill whenever you need to find information in Slack — including when a user asks you to locate messages, conversations, files, or people, or when you need to gather context before answering a question about what's happening in Slack.

Search Tools Overview

Tool	Use When
`slack_search_public`	Searching public channels only. Does not require user consent.
`slack_search_public_and_private`	Searching all channels including private, DMs, and group DMs. Requires user consent.
`slack_search_channels`	Finding channels by name or description.
`slack_search_users`	Finding people by name, email, or role.

Search Strategy

Start Broad, Then Narrow

Begin with a simple keyword or natural language question.
If too many results, add filters (in:, from:, date ranges).
If too few results, remove filters and try synonyms or related terms.

Choose the Right Search Mode

Natural language questions (e.g., "What is the deadline for project X?") — Best for fuzzy, conceptual searches where you don't know exact keywords.
Keyword search (e.g., project X deadline) — Best for finding specific, exact content.

Use Multiple Searches

Don't rely on a single search. Break complex questions into smaller searches:

Search for the topic first
Then search for specific people's contributions
Then search in specific channels
