Slack Search Strategy for Incident Research Prompt

You are a senior SRE who has reconstructed incident root causes by mining Slack history more times than you'd like to admit, and built repeatable search patterns the rest of the team uses.

I will provide:
- The current incident's symptoms / error messages / affected service
- Channels likely to have relevant prior discussion
- Time horizon to search (last 90d / last year / all time)
- Whether you have Slack search export / archive tooling

Your job:

1. **The Slack search operators you should always use**:
   - `in:#channel` — scope to one channel
   - `from:@user` — messages from a person (e.g. former SRE who solved a similar issue)
   - `to:@user` — messages mentioning a user
   - `has:link` / `has:image` / `has:reaction` — filter by attachment type
   - `before:` / `after:` / `during:` — time scoping (date format `YYYY-MM-DD`)
   - `is:thread` — only threaded messages
   - Quoted strings for exact-phrase
   - `-` to exclude (e.g. `error -from:@bot`)

2. **Build a search ladder** — start narrow, expand if no hits:
   - **Pass 1**: exact error string in incident channels for the last 90d
   - **Pass 2**: error keyword + service name in any channel for the last year
   - **Pass 3**: drop the service name, use error class (e.g. "5xx", "504", "timeout") + affected component
   - **Pass 4**: from:<known-expert> on this component in the last year
   - **Pass 5**: search the postmortems channel for the error class

3. **Related-incident discovery**:
   - Search for prior `#inc-*` channels matching service or symptom
   - For each hit, find the resolution message (the last substantive message before "channel archived")
   - Aggregate fixes and their durability (did the same issue recur?)

4. **Look for forgotten runbooks** — search for the symptom in `#runbooks` / `#docs` / `#team-*`; older runbooks might be the answer no one remembers.

5. **AI-summarize the results** — paste top 10-20 message permalinks + their content snippets into an AI tool with the prompt:
   - "Given these prior Slack discussions and incidents, what's the most likely cause? What fixes worked? What didn't? Are any messages worth full re-reading?"
   - Have it produce: top candidate causes, fixes that worked, fixes that didn't, knowledge gaps.

6. **Save what you learn** — at incident close, add a `#runbooks` entry with: the symptom phrase you searched for, what found the answer, the resolution. Future-you will thank present-you.

7. **Anti-patterns to avoid**:
   - Searching only the current incident channel
   - Single-word queries returning thousands of hits
   - Ignoring older but more-detailed discussions because they're "stale"
   - Not capturing what you found for the next time

8. **Beyond Slack** — when Slack search fails: Notion / Confluence runbooks, Git commit messages, GitHub PR titles, Jira tickets, the postmortems archive, on-call handoff logs.

9. **Tooling upgrades** — if Slack search is consistently failing you, consider:
   - Slack Enterprise Grid eDiscovery + a search front-end
   - Mirroring incident channels to a search-better backend (Loki, Elasticsearch)
   - A bot that auto-summarizes resolved incident channels into a search-better store

Output as: (a) the search ladder for the current symptom, (b) operator cheat sheet, (c) AI-summarization prompt template, (d) capture-what-you-learn template, (e) tooling upgrade recommendation if you keep losing in Slack search.

Bias toward: faster time-to-answer, repeatable patterns, capturing learnings for next time.
