Skills anthropics knowledge-work-plugins Enterprise Search

source-management

Use it when:
The agent searches your company's tools through MCP and you want it to know which sources it can reach.
It does:
Detects connected chat, email, cloud storage, project tracker, CRM and knowledge base sources, and tells you how to connect missing ones.
Priorities:
Orders sources by question type, such as chat first for decisions, the project tracker for status and the wiki for policy.
Rate limits:
Doesn't retry a throttled source right away, carries on with the others and tells you which results are missing.
Runs:
On its own when needed; user-invocable: false hides it from the slash menu.

Skill 2 of 4 in the Enterprise Search bundle, after search and before search-strategy.

TL;DR

A support skill of the enterprise-search plugin that keeps track of the sources a search can use. A source counts as connected when its MCP tools are available. When few or none are, or you ask about one that isn't, it lists what's connected and explains how to add a server in your MCP settings. It sets an order of sources for each kind of question, used to weight results rather than to skip sources: chat, then email and documents, for decisions; the project tracker first for status; cloud storage first for documents; chat and task assignees for people; the wiki first for policy. On a rate limit, such as an HTTP 429, it doesn't retry immediately, continues with the other sources and says which one to retry later; it also avoids needless and repeated calls. It reports which sources were searched, and which are available, not connected or rate limited, so you know how complete an answer is. Sources added to the plugin's .mcp.json are picked up by its search and digest commands automatically.

Category

Office files, notes and suites like Lark and Google Workspace.

Type

Knowledge and rules the agent applies while it works: best practices, design principles, API references.

Effect

Adds no side effects of its own. It shapes how the agent thinks, writes or reviews. Guidelines and routers are always effect:none, even when the task they support edits code.

Needs

Needs an MCP server connected.

Publisher

A verified publisher on skills.sh, or the company or maintainer behind the product the skill operates.

Source Management

If you see unfamiliar placeholders or need to check which tools are connected, see CONNECTORS.md.

Knows what sources are available, helps connect new ones, and manages how sources are queried.

Checking Available Sources

Determine which MCP sources are connected by checking available tools. Each source corresponds to a set of MCP tools:

Source Key capabilities
~~chat Search messages, read channels and threads
~~email Search messages, read individual emails
~~cloud storage Search files, fetch document contents
~~project tracker Search tasks, typeahead search
~~CRM Query records (accounts, contacts, opportunities)
~~knowledge base Semantic search, keyword search

If a tool prefix is available, the source is connected and searchable.

Guiding Users to Connect Sources

When a user searches but has few or no sources connected:

You currently have [N] source(s) connected: [list].

To expand your search, you can connect additional sources in your MCP settings:
- ~~chat — messages, threads, channels
- ~~email — emails, conversations, attachments
- ~~cloud storage — docs, sheets, slides
- ~~project tracker — tasks, projects, milestones
- ~~CRM — accounts, contacts, opportunities
- ~~knowledge base — wiki pages, knowledge base articles

The more sources you connect, the more complete your search results.

When a user asks about a specific tool that is not connected:

[Tool name] isn't currently connected. To add it:
1. Open your MCP settings
2. Add the [tool] MCP server configuration
3. Authenticate when prompted

Once connected, it will be automatically included in future searches.

Source Priority Ordering

Different query types benefit from searching certain sources first. Use these priorities to weight results, not to skip sources:

By Query Type

Decision queries ("What did we decide..."):

1. ~~chat (conversations where decisions happen)
2. ~~email (decision confirmations, announcements)
3. ~~cloud storage (meeting notes, decision logs)
4. Wiki (if decisions are documented)
5. Task tracker (if decisions are captured in tasks)

Status queries ("What's the status of..."):

1. Task tracker (~~project tracker — authoritative status)
2. ~~chat (real-time discussion)
3. ~~cloud storage (status docs, reports)
4. ~~email (status update emails)
5. Wiki (project pages)

Document queries ("Where's the doc for..."):

1. ~~cloud storage (primary doc storage)
2. Wiki / ~~knowledge base (knowledge base)
3. ~~email (docs shared via email)
4. ~~chat (docs shared in channels)
5. Task tracker (docs linked to tasks)

People queries ("Who works on..." / "Who knows about..."):

1. ~~chat (message authors, channel members)
2. Task tracker (task assignees)
3. ~~cloud storage (doc authors, collaborators)
4. ~~CRM (account owners, contacts)
5. ~~email (email participants)

Factual/Policy queries ("What's our policy on..."):

1. Wiki / ~~knowledge base (official documentation)
2. ~~cloud storage (policy docs, handbooks)
3. ~~email (policy announcements)
4. ~~chat (policy discussions)
Default Priority (General Queries)

When query type is unclear:

1. ~~chat (highest volume, most real-time)
2. ~~email (formal communications)
3. ~~cloud storage (documents and files)
4. Wiki / ~~knowledge base (structured knowledge)
5. Task tracker (work items)
6. CRM (customer data)

Rate Limiting Awareness

MCP sources may have rate limits. Handle them gracefully:

Detection

Rate limit responses typically appear as:

  • HTTP 429 responses
  • Error messages mentioning "rate limit", "too many requests", or "quota exceeded"
  • Throttled or delayed responses
Handling

When a source is rate limited:

  1. Do not retry immediately — respect the limit
  2. Continue with other sources — do not block the entire search
  3. Inform the user:
Note: [Source] is temporarily rate limited. Results below are from
[other sources]. You can retry in a few minutes to include [source].
  1. For digests — if rate limited mid-scan, note which time range was covered before the limit hit
Prevention
  • Avoid unnecessary API calls — check if the source is likely to have relevant results before querying
  • Use targeted queries over broad scans when possible
  • For digests, batch requests where the API supports it
  • Cache awareness: if a search was just run, avoid re-running the same query immediately

Source Health

Track source availability during a session:

Source Status:
  ~~chat:        ✓ Available
  ~~email:        ✓ Available
  ~~cloud storage:  ✓ Available
  ~~project tracker:        ✗ Not connected
  ~~CRM:   ✗ Not connected
  ~~knowledge base:      ⚠ Rate limited (retry in 2 min)

When reporting search results, include which sources were searched so the user knows the scope of the answer.

Adding Custom Sources

The enterprise search plugin works with any MCP-connected source. As new MCP servers become available, they can be added to the .mcp.json configuration. The search and digest commands will automatically detect and include new sources based on available tools.

To add a new source:

  1. Add the MCP server configuration to .mcp.json
  2. Authenticate if required
  3. The source will be included in subsequent searches automatically
