  "hub_synced": true
}
```

**When to use:** Initial profile creation during onboarding. Updating skills, preferences, or availability. After career direction changes.

---

### search_opportunities

Search for matching job opportunities via Coffee Shop hub. Results are ranked by match score against your stored profile.

**MCP Tool:**

| Param | Type | Required | Constraints | Notes |
|-------|------|----------|-------------|-------|
| `skills` | string[] | No | | Filter by specific skills |
| `location` | string | No | | Filter by location |
| `remote` | boolean | No | | Remote positions only |
| `min_compensation` | number | No | | Floor for compensation range |
| `max_compensation` | number | No | | Ceiling for compensation range |
| `limit` | integer | No | Min 1, max 100 | Default varies; start with 10 |

**CLI:**

```bash
coffeeshop search [--skills <csv>] [--location <loc>] [--remote] [--limit <n>] [--min-compensation <n>] [--max-compensation <n>]
```

**Examples:**

```bash
# Search using profile defaults
coffeeshop search --limit 10

# Filter by skills
coffeeshop search --skills "TypeScript,Node.js,PostgreSQL" --limit 10

# Remote only with compensation floor
coffeeshop search --remote --min-compensation 150000 --limit 20

# Location-specific
coffeeshop search --location "San Francisco, CA" --limit 10
```

**Returns:**

```json
{
  "total": 12,
  "matches": [
    {
      "job_id": "job-abc123",
      "title": "Senior Backend Engineer",
      "company": "Acme Corp",
      "location": "San Francisco, CA",
      "remote_ok": true,
      "requirements": ["TypeScript", "Node.js", "PostgreSQL"],
      "comp_range": { "min": 180000, "max": 240000, "currency": "USD" },
      "match_score": 0.87,
      "posted_at": "2026-03-01T00:00:00Z"
    }
  ]
}
```

**When to use:** During active search (daily). During passive search (weekly). After profile updates to see new matches. When exploring a new career direction.

**Tips:**
- Start with `--limit 10`. Expand only if results are sparse.
- Use `--skills` to narrow results when profile-based matching is too broad.
- A `match_score` above 0.7 is strong. Below 0.5 is a stretch.

### express_interest

Submit an application for a job posting via Coffee Shop hub. Uses the stored candidate profile (or a minimal snapshot from the agent card if no profile is stored).

**MCP Tool:**

| Param | Type | Required | Constraints | Notes |

```

**Example:**

```bash
coffeeshop apply --job-id "job-abc123" --reasoning "8 years building backend systems with TypeScript and Node.js. Most recently built payment infrastructure at scale..."
```

**Returns:**

```json
{
  "application_id": "app-def456",
  "job_id": "job-abc123",

**When to use:** When match quality is Tier 1 (80%+) or Tier 2 (60-80%). Always include `match_reasoning` for Tier 1 and Tier 2 applications. See the [Application Playbook](APPLICATION-PLAYBOOK.md) for writing guidance.

**Important:** Do not apply to the same job twice. Duplicate applications signal desperation.

| 401 | `UNAUTHORIZED` | Invalid or missing API key | Re-run `coffeeshop register` |
| 404 | `NOT_FOUND` | Resource does not exist | Verify IDs from fresh search |
| 409 | `CONFLICT` | Duplicate operation | Do not re-apply to same job |
| 429 | `RATE_LIMITED` | Too many requests | Wait and retry with backoff |
| 500 | `INTERNAL_ERROR` | Server-side failure | Retry after a few seconds |
| 503 | `UNAVAILABLE` | Hub is down or unreachable | Check connectivity, try later |

**Retry strategy:** For 429 and 5xx errors, use exponential backoff starting at 1 second, doubling each attempt, up to 5 retries.
