# gdd-intel-updater

**Role:** Keep the `.design/intel/` store in sync with the design surface after any file changes.

## When to invoke

- After completing any phase plan that edits skill/agent/reference/connection files
- When `/gdd:health` reports intel store staleness
- Manually via `/gdd:update intel` (future command)

## Protocol

### Step 1 - Check intel store exists

```bash
ls .design/intel/files.json 2>/dev/null && echo "exists" || echo "missing"
```

If missing: run full build (Step 2 with `--force`). If exists: proceed to Step 2 without `--force`.

### Step 2 - Run incremental build

```bash
node scripts/build-intel.cjs
```

Capture output. If output contains "no changes detected", report "Intel store current - no update needed" and stop.

### Step 3 - Verify slices written

Confirm all ten slices present:

```bash
ls .design/intel/*.json
```

Expected: `components.json decisions.json debt.json dependencies.json exports.json files.json graph.json patterns.json symbols.json tokens.json`

Report any missing slices as warnings.

### Step 3.5 - Sync `.design/intel/agent-tiers.json`

The runtime-neutral `reasoning-class` alias for `default-tier` lets downstream tooling read tier information without re-parsing markdown via `.design/intel/agent-tiers.json`. Both fields MUST be populated per agent so consumers do not have to know the equivalence table - the intel-updater is the single source of truth that fills the missing field via the locked map:

| `reasoning-class` | `default-tier` |
|-------------------|----------------|
| `high`            | `opus`         |
| `medium`          | `sonnet`       |
| `low`             | `haiku`        |

Walk every `agents/*.md` file (skip `README.md`), parse its frontmatter, and emit one entry per agent into `.design/intel/agent-tiers.json` with the shape:

```json
{
  "schema_version": 1,
  "generated_at": "<ISO-8601-UTC>",
  "agents": {
    "design-planner": { "default-tier": "opus", "reasoning-class": "high" },
    "design-verifier": { "default-tier": "haiku", "reasoning-class": "low" }
  }
}
```

Population rules:

1. If both `default-tier` and `reasoning-class` are present in the agent's frontmatter, write both verbatim (validator already enforced equivalence at lint time - see `scripts/validate-frontmatter.ts`).
2. If only `default-tier` is present (the v1.26 baseline state for all 26 shipped agents), derive `reasoning-class` from the table above and write both.
3. If only `reasoning-class` is present, derive `default-tier` from the table above and write both.
4. If neither is present, omit the agent from the JSON and emit a warning - the upstream `validate-frontmatter` gate would have caught this at CI; the intel-updater stays non-throwing on lint-edges.

Validation is exclusively the validator's job; this step assumes the gate has passed and writes the queryable index. If a pre-existing `.design/intel/agent-tiers.json` is present, overwrite it atomically (write to a `.tmp` then `rename`).

### Step 4 - Report summary

Print a concise update summary:

```
━━━ Intel store updated ━━━
Files indexed:  <N>
Changed files:  <N>
Slices written: 11 (10 build-intel slices + agent-tiers.json from Step 3.5)
Generated:      <timestamp>
━━━━━━━━━━━━━━━━━━━━━━━━━━
```

## Required reading (conditional)

@.design/intel/files.json (if present)

## Slice staleness detection

A slice is stale if its `generated` timestamp is older than the newest `mtime` in `files.json`.
The updater does not need to check this manually - `build-intel.cjs` handles mtime comparison.

## Record

At run-end, append one JSONL line to `.design/intel/insights.jsonl`:

```json
{"ts":"<ISO-8601>","agent":"<name>","cycle":"<cycle from STATE.md>","stage":"<stage from STATE.md>","one_line_insight":"<what was produced or learned>","artifacts_written":["<files written>"]}
```

Schema: `reference/schemas/insight-line.schema.json`. Use an empty `artifacts_written` array for read-only agents.
