Glean

When to Use This Skill

Trigger conditions

Trigger this skill when the user mentions "glean" combined with an action intent:

• "glean search vacation policy" / "用 glean 搜一下请假规定"
• "glean chat summarize Q1 goals" / "问一下 glean 季度目标"
• "search company docs" / "搜公司知识库" / "搜内部文档"
• "glean agents list" / "glean documents get"
• "glean shortcuts create" / "create a go-link"
• "glean api" / "look up people in glean" / "glean 查人"

NOT a trigger (do NOT invoke this skill):

• Generic web search not targeting company knowledge
• User asks to search GitHub issues/PRs — use gh-operations
• User asks to search Confluence — use confluence skill

Security — MANDATORY rules for AI agents

1. NEVER echo, print, or log the values of any environment variable containing credentials (GLEAN_API_TOKEN, etc.). Do NOT run commands like echo $GLEAN_API_TOKEN or printenv GLEAN_API_TOKEN — even for debugging.
2. NEVER pass token/credential values as inline CLI arguments or env-var overrides. glean reads credentials from its own config or environment — just run glean commands directly.
3. NEVER read environment variable values using shell commands or programmatic access. The AI agent should not inspect, verify, or access token values in any way.
4. When debugging auth errors, rely solely on glean auth status output and glean error messages. Do NOT attempt to verify tokens by reading or printing them.
5. NEVER extract credentials from OS credential stores or config files. Strictly forbidden commands include:

• macOS Keychain: security find-internet-password, security find-generic-password
• Reading ~/.glean/config.json or any glean auth config file
• Any command that outputs a password, token, or secret value from any credential store

1. NEVER use extracted credential values in commands. The glean CLI handles all authentication internally — use glean api for API calls instead of curl with raw tokens.

Runtime requirements

• Glean CLI (glean) installed and authenticated
• Run skills-check glean to verify dependencies

Workflow

1) Pre-flight checks

MANDATORY execution rule:

• If the user provides a clear glean action (e.g., "glean search X"), go straight to the relevant operation. Do NOT run glean --version or glean auth status first — let the command succeed or fail.
• If running glean for the first time or encountering auth errors, check:

1. Verify glean exists:

``bash glean --version ``

1. Verify authentication:

``bash glean auth status ``

1. If not authenticated:

``bash glean auth login # OAuth via browser (recommended) ``

1. For CI/CD environments, credentials are set via environment variables:

• GLEAN_API_TOKEN — API token
• GLEAN_HOST — Glean backend hostname (e.g. your-company-be.glean.com)

2) Search (glean search)

Search across company knowledge:

glean search "vacation policy"
glean search "Q1 planning" --datasource confluence --page-size 5
glean search "docs" --output ndjson | jq .title
glean search "onboarding" --fields "results.document.title,results.document.url"
glean search --json '{"query":"onboarding","pageSize":3}'
glean search --dry-run "test"

| Flag | Description | |---|---| | --output / --format | json (default), ndjson (one result per line), text | | --fields | Dot-path field projection — prefix paths with results. | | --datasource / -d | Filter by datasource (repeatable) | | --type / -t | Filter by document type (repeatable) | | --page-size | Results per page (default 10) | | --json | Raw SDK request body (overrides all flags) | | --dry-run | Print request body without sending |

3) Chat (glean chat)

Chat with Glean Assistant (non-interactive):

glean chat "What are our company holidays?"
glean chat --timeout 120000 "Summarize all Q1 OKRs across teams"
glean chat --json '{"messages":[{"author":"USER","messageType":"CONTENT","fragments":[{"text":"What is Glean?"}]}]}'
echo "What is Glean?" | glean chat
glean chat    # interactive multiline input, Ctrl+D to send

| Flag | Description | |---|---| | --timeout | Request timeout in milliseconds (default 60000) | | --json | Raw SDK request body (overrides all flags) | | --dry-run | Print request body without sending | | --save | Persist chat for continuation (default true) |

4) Schema introspection (glean schema)

Discover commands and flags programmatically:

glean schema | jq '.commands'
glean schema search | jq '.flags | keys'
glean schema search | jq '.flags["--output"]'

5) AI Agents (glean agents)

glean agents list | jq '.agents[] | {id: .agent_id, name: .name}'
glean agents get --json '{"agentId":""}'
glean agents schemas --json '{"agentId":""}'
glean agents run --json '{"agentId":"","messages":[{"author":"USER","fragments":[{"text":"summarize Q1 results"}]}]}'

6) Documents (glean documents)

glean documents get --json '{"documentSpecs":[{"url":"https://..."}]}'
glean documents summarize --json '{"documentSpecs":[{"url":"https://..."}]}'

7) Collections (glean collections)

glean collections list
glean collections get --json '{"id":""}'
glean collections create --json '{"name":"My Collection","description":"..."}'
glean collections add-items --json '{"id":"","addedDocumentSpecs":[{"url":"https://..."}]}'

8) Shortcuts / go-links (glean shortcuts)

glean shortcuts list
glean shortcuts create --json '{"data":{"inputAlias":"onboarding","destinationUrl":"https://..."}}'
glean shortcuts create --json '{"data":{"inputAlias":"jira","urlTemplate":"https://jira.example.com/browse/{arg}"}}'

9) Other namespace commands

All namespace commands accept --json, --output, and --dry-run.

| Namespace | Subcommands | Description | |---|---|---| | glean answers | list, get, create, update, delete | Curated Q&A pairs | | glean announcements | create, update, delete | Company announcements | | glean pins | list, get, create, update, remove | Promoted search results | | glean entities | list, read-people | People, teams, custom entities | | glean verification | list, verify, remind | Document verification | | glean insights | get | Search and usage analytics | | glean messages | get | Indexed messages (Slack, Teams) | | glean activity | report, feedback | User activity reporting | | glean tools | list, run | Platform tools |

10) Raw API access (glean api)

glean api search --method POST --raw-field '{"query":"rust","pageSize":3}'
glean api --preview search --method POST --raw-field '{"query":"test"}'

11) Interactive TUI

Running glean with no arguments opens a full-screen chat:

glean            # open TUI
glean --continue # resume the most recent session

Output Expectations

For every task, provide:

1. Commands executed (or planned) in code blocks
2. Short result summary
3. If write operation succeeded, include the result explicitly
4. If operation fails, include exact error and next action

All glean commands return structured JSON on stdout and errors on stderr. Use jq for parsing. Use --dry-run to preview requests before sending.

Error Handling

• glean not installed: Tell user to install via brew install gleanwork/tap/glean-cli or the install script. Run skills-check glean to verify.
• Not authenticated: Run glean auth login (OAuth via browser). For CI/CD, set GLEAN_API_TOKEN and GLEAN_HOST environment variables.
• Auth failure — ONLY allowed recovery steps:

1. Report the glean error message to the user
2. Suggest glean auth login or glean auth status
3. For token-based auth, suggest checking GLEAN_API_TOKEN and GLEAN_HOST are set
4. Stop and wait for the user to fix auth

• API errors: Report status code and error body. Use --dry-run to debug request shape.
• Unknown command: Use glean schema to discover available commands and flags.

Notes

• Every command returns JSON — pipe to jq for field extraction.
• Use --dry-run to preview requests before sending.
• Use glean schema for machine-readable flag documentation.
• Use --output ndjson for streaming large result sets.
• The interactive TUI (glean with no args) is for human-interactive sessions; prefer glean chat "..." or glean search "..." for agent workflows.
