Query Integration Data Skill

Connect to any Replit-supported integration to read or write data — query issues, create tickets, send messages, update contacts, manage files, etc. This also includes querying supported data warehouse integrations like Databricks, Snowflake, and BigQuery.

All code runs inline in the code_execution sandbox — no script files needed.

When to Use

Use this skill when the user asks you a question in chat that requires data from external services to answer, or when they need to perform data operations without building a visual interface.

• Answer questions: Query data to respond to user questions in the conversation (e.g., "How many issues were created this week?")
• Fetch and export data: Export data to CSV/JSON for later use or analysis
• Write operations: Create, update, delete, or modify data in a service
• Ad-hoc queries: One-time data lookups or investigations
• Automate tasks: Perform multi-step operations across the API

Key point: Use this skill when the output is an answer or data file, NOT when building a dashboard or visualization interface.

When NOT to Use

• The user wants to create a dashboard, visualization, or analytics interface - use the data-visualization skill (it handles data fetching internally)
• The user asks to "build", "create", or "make" a dashboard/app with data - use the data-visualization skill
• The user needs to add an integration to their app (use the integrations skill)
• Production database operations (use the database pane directly)
• Asks to check deployment or server logs (use the deployment skill)

File Structure

.agents/
└── outputs/         # Generated artifacts (CSV, JSON, etc.)

Code runs inline in the code_execution sandbox — no script files are needed.

Workflow

1. CHECK      → listConnections(connectorName) to get existing credentials
   ├─ connections exist → EXECUTE → OUTPUT
   └─ empty array      → SEARCH → LEARN → CLARIFY → setup via `integrations` skill → EXECUTE → OUTPUT

• CHECK: Call listConnections(connectorName) in the code_execution sandbox. If it returns connections, you already have credentials — skip straight to EXECUTE.
• SEARCH → CONNECT (only when no connections exist): Use searchIntegrations, proposeIntegration, and addIntegration to set up a new connection. See the integrations skill for the full lifecycle details.
• EXECUTE: Write and run code in the code_execution sandbox.
• OUTPUT: Return the answer or confirmation to the user.

Getting Connection Credentials

Primary: listConnections(connectorName)

This is the main way to get credentials. It's a pre-registered function in the code_execution sandbox.

const conns = await listConnections('linear');
console.log(conns.map(c => ({ id: c.id, displayName: c.displayName, status: c.status })));

Each connection object has:

• id, connectorConfigId, status, displayName, metadata, environment
• settings — credentials dict (access tokens, API keys, etc.)
• getClient() — returns the settings object for constructing SDK clients

Returns an empty array when no connections are configured.

const conns = await listConnections('linear');
if (conns.length > 0) {
  const token = conns[0].settings.access_token;
  const { LinearClient } = await import('@linear/sdk');
  const client = new LinearClient({ accessToken: token });
  // Ready to query
}

Fallback: Setting Up a New Connection

If listConnections returns an empty array, the user hasn't connected the service yet. Use searchIntegrations to find the connector, then follow the integrations skill to walk the user through setup (addIntegration and proposeIntegration — order depends on integration type). After the connection is established, listConnections will return it.

Browse the Documentation

Always browse public_documentation_link before writing code, especially for write operations. This helps you understand:

• Required vs optional fields for creating resources
• Valid values for enums (status, priority, type, etc.)
• Relationships between resources (e.g., issues belong to projects)
• Rate limits and best practices

Clarifying Questions

Before write operations, gather required information. Many APIs require IDs or specific values that the user may not know.

When to Ask

Ask clarifying questions when the user's request requires:

• Entity selection: "Which project should this issue be created in?"
• User assignment: "Who should be assigned? Let me list the team members..."
• Required fields: "What priority - urgent, high, medium, or low?"
• Ambiguous references: "I found 3 projects matching 'backend'. Which one?"

Pattern: Fetch Options First

For write operations, often run a read query first to get valid options:

// User says: "Create a Linear ticket assigned to John"
// Problem: Need John's user ID, not just name

const conns = await listConnections('linear');
const { LinearClient } = await import('@linear/sdk');
const client = new LinearClient({ accessToken: conns[0].settings.access_token });

// Step 1: List users to find John's ID
const users = await client.users();
const john = users.nodes.find(u => u.name.includes('John'));

// Step 2: If ambiguous, ASK the user
// "I found John Smith and John Doe. Which one?"

// Step 3: Create with correct ID
await client.createIssue({ assigneeId: john.id, ... });

Common Multi-Step Patterns

Running Code in the Sandbox

All code runs in the code_execution sandbox. State persists across calls (notebook-style), so variables from one call are available in subsequent calls.

Read Operations

Query data and return results:

const conns = await listConnections('linear');
const { LinearClient } = await import('@linear/sdk');
const client = new LinearClient({ accessToken: conns[0].settings.access_token });

const issues = await client.issues({ first: 10 });
console.log(`Found ${issues.nodes.length} issues`);
for (const issue of issues.nodes) {
  console.log(`${issue.identifier}: ${issue.title} [${issue.state?.name}]`);
}

Write Operations

Create, update, or delete data:

const conns = await listConnections('linear');
const { LinearClient } = await import('@linear/sdk');
const client = new LinearClient({ accessToken: conns[0].settings.access_token });

// Create
const created = await client.createIssue({ teamId: team.id, title: "Fix login bug" });
console.log(`Created: ${created.issue?.identifier}`);

// Update
await client.updateIssue(issueId, { stateId: doneState.id });
console.log(`Updated: ${issueId}`);

// Delete
await client.deleteIssue(issueId);
console.log(`Deleted: ${issueId}`);

Multi-Step Operations

Variables persist across code_execution calls, enabling multi-step workflows:

// Call 1: Get credentials and list teams
const conns = await listConnections('linear');
const { LinearClient } = await import('@linear/sdk');
const client = new LinearClient({ accessToken: conns[0].settings.access_token });

const teams = await client.teams();
const team = teams.nodes[0];
console.log(`Using team: ${team.name}`);

const users = await client.users();
const assignee = users.nodes.find(u => u.name === 'John');
console.log(`Found assignee: ${assignee?.name}`);

// Call 2: Variables from Call 1 are still available
const issue = await client.createIssue({
  teamId: team.id,
  assigneeId: assignee?.id,
  title: 'New feature request',
  description: 'Details here...',
});
console.log(`Created ${issue.issue?.identifier}: New feature request`);

Warehouse Data Exploration

When querying data warehouses (BigQuery, Snowflake, Databricks), large schemas can make serial exploration slow (7-10s per query round-trip). Use the parallel subagent pattern to explore schemas faster.

When to Use Parallel Exploration

Use this pattern when ALL of the following are true:

• The target is a warehouse connection (bigquery, snowflake, or databricks)
• The initial INFORMATION_SCHEMA query returns 15+ tables
• The user's question is not about a specific known table (e.g., they're asking a broad question like "what's our revenue trend?" or "show me customer data")

If the schema has fewer than 15 tables, serial exploration is fast enough — just query tables one-by-one.

4-Step Parallel Workflow

Step 1: Schema Discovery — Run a single executeSql call to get the full table list.

// BigQuery
const tables = await executeSql({ sqlQuery: `SELECT table_schema, table_name, row_count FROM \`project.region-us\`.INFORMATION_SCHEMA.TABLES WHERE table_schema NOT IN ('INFORMATION_SCHEMA') ORDER BY table_schema, table_name`, target: "bigquery" });

// Snowflake
const tables = await executeSql({ sqlQuery: `SELECT TABLE_SCHEMA, TABLE_NAME, ROW_COUNT FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA NOT IN ('INFORMATION_SCHEMA') ORDER BY TABLE_SCHEMA, TABLE_NAME`, target: "snowflake" });

// Databricks
const tables = await executeSql({ sqlQuery: `SELECT table_schema, table_name FROM information_schema.tables WHERE table_schema NOT IN ('information_schema') ORDER BY table_schema, table_name`, target: "databricks" });

Step 2: Group Tables — Partition the table list into 2-4 clusters:

• By schema/dataset name (e.g., analytics.*, sales.*, marketing.*)
• By name prefix (e.g., dim_*, fact_*, stg_*)
• By estimated relevance to the user's question (most-likely-relevant tables first)

Step 3: Launch Parallel Subagents — Start one SMALL_TASK subagent per group:

const group1 = await startAsyncSubagent({
  task: `Explore these warehouse tables to answer: "${userQuestion}"

Connection: Use executeSql({ sqlQuery: "...", target: "bigquery" }) — always pass target.
Dialect: BigQuery (use backtick quoting for project.dataset.table)

Tables to explore:
- analytics.events
- analytics.sessions
- analytics.conversions

For each table:
1. Run: SELECT column_name, data_type FROM \`project.dataset\`.INFORMATION_SCHEMA.COLUMNS WHERE table_name = 'TABLE_NAME'
2. Run: SELECT * FROM \`project.dataset.TABLE_NAME\` LIMIT 5

Return your findings in this exact format:

## Table Relevance
| Table | Relevant? | Why |
|-------|-----------|-----|
| ... | Yes/No | Brief reason |

## Column Details (relevant tables only)
| Table | Column | Type | Notes |
|-------|--------|------|-------|
| ... | ... | ... | Key field, foreign key, metric, etc. |

## Suggested Join Conditions
- table_a.id = table_b.a_id (describe relationship)

## Key Findings
- Bullet points about data patterns, date ranges, notable values`,
  specialization: 'SMALL_TASK',
  relevantFiles: ['.local/skills/database/SKILL.md']
});

// Launch additional subagents for other groups (2-4 total)
const group2 = await startAsyncSubagent({ /* same pattern, different tables */ });

Step 4: Synthesize and Query — Wait for all subagents, then write the final query:

await waitForBackgroundTasks();
// Read subagent outputs, combine relevant tables/columns, write the final SQL query

Dialect-Specific Notes

Tips

• Each subagent should run 3-6 SQL queries (column metadata + sample data per table)
• Keep subagent count to 2-4 — more than 4 has diminishing returns
• The structured markdown output format ensures consistent, scannable results
• After synthesis, write a single well-commented SQL query that answers the user's question

Output Guidelines

• Simple answers (counts, scalar values, short lists of < 20 records): Print directly with console.log()
• Complex results (tabular results): Write to .agents/outputs/<filename>.csv and summarize
• Write confirmations: Print what was created/updated/deleted with IDs
• Errors: Print clear error messages

const fs = await import('fs');

// Simple
console.log(`Answer: 42 issues created this week`);

// Tabular results - write CSV to .agents/outputs/
fs.mkdirSync('.agents/outputs', { recursive: true });
fs.writeFileSync('.agents/outputs/results.csv', csvContent);
console.log(`Exported 500 records to .agents/outputs/results.csv`);

// Write
console.log(`Created issue ENG-123: "Fix login bug"`);
console.log(`Updated 5 contacts`);
console.log(`Deleted message ID abc123`);

Key Points

• Use listConnections(connectorName) as the primary way to get credentials
• Fall back to search → propose → add when no connections exist (see integrations skill)
• All code runs in the code_execution sandbox — no script files needed
• Use console.log() to see output — functions execute silently without it (but never log credentials)
• Use await import(...) for packages (dynamic imports only)
• State persists across code_execution calls — reuse conns, clients, and extracted credentials instead of re-fetching (unless expired).
• Browse public_documentation_link to understand the API before coding
• Ask clarifying questions before write operations that need specific IDs or values
• Fetch options first when the user references something by name (users, projects, etc.)
• Don't cache clients — access tokens expire; re-create clients from listConnections when needed
• Write large outputs to .agents/outputs/ as CSV or JSON
