# Sourcegraph Management Skill

Manage and monitor Sourcegraph repositories, search indexes, batch changes, and code intelligence.

## MANDATORY: Discovery-First Pattern

**Always check instance health and repository status before querying specific resources.**

### Phase 1: Discovery

```bash
#!/bin/bash

SG_API="${SOURCEGRAPH_URL}/.api"

sg_gql() {
    curl -s -H "Authorization: token $SOURCEGRAPH_TOKEN" \
         -H "Content-Type: application/json" \
         "${SG_API}/graphql" \
         -d "{\"query\": \"$1\"}"
}

sg_api() {
    curl -s -H "Authorization: token $SOURCEGRAPH_TOKEN" \
         "${SG_API}/${1}"
}

echo "=== Sourcegraph Instance ==="
sg_gql "{ site { productVersion configuration { effectiveContents } } }" | jq '{
    version: .data.site.productVersion
}'

echo ""
echo "=== External Services ==="
sg_gql "{ externalServices(first: 20) { nodes { displayName kind lastSyncAt lastSyncError } } }" | jq -r '
    .data.externalServices.nodes[] |
    "\(.displayName)\t\(.kind)\t\(.lastSyncAt[:16] // "never")\t\(.lastSyncError // "ok" | .[0:30])"
' | column -t

echo ""
echo "=== Repositories (indexed) ==="
sg_gql "{ repositories(first: 30, indexed: true, orderBy: REPOSITORY_NAME) { totalCount nodes { name } } }" | jq -r '
    "Total indexed: \(.data.repositories.totalCount)",
    (.data.repositories.nodes[] | .name)
' | head -20

echo ""
echo "=== Users ==="
sg_gql "{ users(first: 20) { totalCount nodes { username emails { email } siteAdmin createdAt } } }" | jq -r '
    .data.users.nodes[] |
    "\(.username)\t\(.emails[0].email // "")\tadmin=\(.siteAdmin)\t\(.createdAt[:10])"
' | column -t | head -15
```

### Phase 2: Analysis

```bash
#!/bin/bash

echo "=== Index Status ==="
sg_gql "{ repositories(first: 10, indexed: false) { totalCount nodes { name } } }" | jq -r '
    "Unindexed repos: \(.data.repositories.totalCount)",
    (.data.repositories.nodes[] | "\(.name)\tNOT INDEXED")
' | head -15

echo ""
echo "=== Batch Changes ==="
sg_gql "{ batchChanges(first: 15) { nodes { name state createdAt namespace { namespaceName } changesetsStats { total open merged closed failed } } } }" | jq -r '
    .data.batchChanges.nodes[] |
    "\(.name)\t\(.state)\topen=\(.changesetsStats.open)\tmerged=\(.changesetsStats.merged)\tfailed=\(.changesetsStats.failed)"
' | column -t | head -15

echo ""
echo "=== Code Insights ==="
sg_gql "{ insightViews(first: 10) { nodes { id title } } }" 2>/dev/null | jq -r '
    .data.insightViews.nodes[]? |
    "\(.id)\t\(.title)"
' | column -t | head -10

echo ""
echo "=== External Service Errors ==="
sg_gql "{ externalServices(first: 20) { nodes { displayName lastSyncError } } }" | jq -r '
    .data.externalServices.nodes[] |
    select(.lastSyncError != null and .lastSyncError != "") |
    "\(.displayName)\tERROR: \(.lastSyncError[:60])"
' | column -t
```

## Output Rules
- **TOKEN EFFICIENCY**: Target <=50 lines per output
- Use GraphQL field selection to minimize response size
- Never dump full file contents or large search results -- extract counts and status

## Output Format

Present results as a structured report:
```
Managing Sourcegraph Report
═══════════════════════════
Resources discovered: [count]

Resource       Status    Key Metric    Issues
──────────────────────────────────────────────
[name]         [ok/warn] [value]       [findings]

Summary: [total] resources | [ok] healthy | [warn] warnings | [crit] critical
Action Items: [list of prioritized findings]
```

Target ≤50 lines of output. Use tables for multi-resource comparisons.

## Anti-Hallucination Rules

1. **NEVER assume resource names** — always discover via CLI/API in Phase 1 before referencing in Phase 2.
2. **NEVER fabricate metric names or dimensions** — verify against the service documentation or `--help` output.
3. **NEVER mix CLI commands between service versions** — confirm which version/API you are targeting.
4. **ALWAYS use the discovery → verify → analyze chain** — every resource referenced must have been discovered first.
5. **ALWAYS handle empty results gracefully** — an empty response is valid data, not an error to retry.

## Counter-Rationalizations

| Shortcut | Counter | Why |
|----------|---------|-----|
| "I'll skip discovery and check known resources" | Always run Phase 1 discovery first | Resource names change, new resources appear — assumed names cause errors |
| "The user only asked for a quick check" | Follow the full discovery → analysis flow | Quick checks miss critical issues; structured analysis catches silent failures |
| "Default configuration is probably fine" | Audit configuration explicitly | Defaults often leave logging, security, and optimization features disabled |
| "Metrics aren't needed for this" | Always check relevant metrics when available | API/CLI responses show current state; metrics reveal trends and intermittent issues |
| "I don't have access to that" | Try the command and report the actual error | Assumed permission failures prevent useful investigation; actual errors are informative |

## Common Pitfalls

- **Index lag**: New repositories take time to index -- check cloning and indexing queue
- **External service sync**: Sync errors prevent repository discovery -- fix external service config
- **Precise code intel**: Requires LSIF/SCIP uploads -- check indexer configuration per language
- **Batch change permissions**: Users need write access to target repos for changesets
- **Search contexts**: Search contexts scope queries -- wrong context returns incomplete results
- **Rate limiting**: Code host rate limits affect syncing -- monitor external service sync intervals
- **Storage growth**: Search indexes and precise code intel data grow with repo count
