# Voices Roster Curator

> Enrich `voices.csv` (at repo root) by finding missing publishing surfaces — Substack, YouTube, blog, podcast, LinkedIn — for the voices already in the roster. Given a name, @handle, or row index, searches the web for the person's surfaces, validates URLs, and updates the CSV in place. Idempotent on re-run; refresh mode re-checks every existing row. Also accepts new voices to add. Composes on source-fetcher + prompt-injection-guard + a CSV writer helper. Use whenever the user wants to broaden voices-watcher's polling reach without manually researching each voice.

# voices-roster-curator

The companion enrichment skill to `voices-watcher`. Where voices-watcher reads `voices.csv` to poll, this skill writes to `voices.csv` to populate the surface URLs that polling needs.

## When to use

- After adding new rows manually to `voices.csv` with only a handle and bio — enrich the surfaces.
- Refreshing existing rows that have only X/Twitter populated (22 of 25 entries as of bootstrap).
- Spot-fix when `voices-watcher`'s digest shows a voice consistently has no items because their RSS URL changed or their newsletter moved.
- Adding a new voice from a recommendation: pass a name + 1 known URL, the skill finds the rest.

## When NOT to use

- Removing voices — that's a manual edit to `voices.csv` (don't automate pruning).
- Validating that a voice is "good signal" for the user — taste call, not automatable.
- Polling new content — that's `voices-watcher`'s job.

## Modes

### `enrich(handle)` — single-row enrichment

For one row, find missing surfaces. Workflow:
1. Read the row from `voices.csv`.
2. Build search queries from `name` + `bio_snippet` + known surfaces (e.g., "{name} site:substack.com", "{name} youtube channel", "{name} podcast").
3. WebSearch + WebFetch via `source-fetcher` to validate candidates (URL resolves, page mentions the person).
4. Each found URL gets confirmation via the `prompt-injection-guard`-cleaned page body containing the person's name AND a published item within 12 months.
5. Update the row's surface columns — fill empty (or non-URL) cells in place only; never reorder or rewrite rows the run didn't touch.
6. Log the enrichment in the `notes` column with a date: `enriched 2026-06-20: +substack +podcast`.
7. Update the matching `vault/people/{handle}.md` note via `vault-writer` with the newly found surfaces (load `vault-conventions` first). If no people note exists for the voice, flag it in the run summary rather than creating one unprompted.

### `refresh()` — sweep mode

Run `enrich(handle)` on every row whose `notes` column doesn't already include a recent `enriched: <date>` (within 90 days). Useful as a periodic catch-up.

### `add(handle, name, twitter_url=None, bio=None)` — new voice

Append a row. Then call `enrich(handle)` to populate surfaces. Confirm with the user before committing if the bio is empty.

## URL validation rules

- **Substack**: resolves to a `*.substack.com` URL or a custom domain whose `/feed` returns valid Atom. Empty Substack stubs (no posts) → skip.
- **YouTube**: channel URL (not video URL); confirm at least 1 video in last 6 months for "active" status.
- **Blog**: any URL with an RSS/Atom feed AND the person identified on the about page.
- **Podcast**: a show-page URL (Apple Podcasts, Spotify, podcaster site); confirm the person is host/co-host.
- **LinkedIn**: profile URL only; skip if profile is locked private.

If multiple candidates resolve, pick the **highest-signal** one (most recently active, most relevant to AI/product/SDLC content). Surface alternatives in `notes` for user review.

## Idempotency

- Re-running `enrich(handle)` on a row with all surfaces populated is a no-op (returns `unchanged: true`).
- Existing populated surfaces are NOT overwritten unless `force=true` is passed. Treat human-curated cells as authoritative.
- **Exception — non-URL values in URL columns**: surface columns (substack/youtube/blog/podcast/linkedin) are expected to hold URLs. If the existing value isn't a valid URL (e.g., a podcast name like "The Twenty Minute VC" instead of a URL), treat as if the column were empty for overwrite purposes — `voices-watcher` can't poll a name. Log the replacement in `notes` for audit.
- The `notes` column accumulates change history; don't truncate it.

## CSV writing

Important: edit `voices.csv` carefully — it's human-readable and human-edited. Preserve column order. Use proper CSV quoting (commas in bios, etc.). Append new rows at the bottom and fill empty cells in place — never reorder rows, and never rewrite rows the skill didn't touch this run.

## Stop and report

- If a candidate URL doesn't resolve, log to the run summary — don't silently skip.
- If the page body fails `prompt-injection-guard` with verdict `suspicious`, do NOT trust its claim of person identity — abandon that candidate and log.
- If two rows in `voices.csv` would collide (e.g., two `johncutlefish` somehow), surface and refuse the write.

## Output

A summary of changes per run:

```
=== voices-roster-curator run 2026-06-20 ===
mode: refresh
rows_checked: 25
rows_updated: 5
new_surfaces_added: 12
candidates_rejected: 3 (page failed prompt-injection-guard | URL 404 | no person match)

```

## Composes with

- `source-fetcher` + `prompt-injection-guard` (URL validation).
- WebSearch (candidate discovery).
- `vault-conventions` + `vault-writer` — keep `vault/people/{handle}.md` notes in sync with enriched surfaces.
- `seen-tracker` — periodic-refresh dedup (avoid re-searching the same handle daily).

## Acceptance test (for step 14 done-criteria)

Run `enrich` on at least 4 voices currently X-only. For each:
- Find ≥1 new surface (Substack, YouTube, blog, or podcast).
- Validate the URL resolves to the person's content.
- Update `voices.csv` preserving column order and quoting.
- Log the enrichment in the `notes` column with `enriched 2026-06-20: +<surfaces>`.
- Surface a clean summary of what changed.

Re-run immediately afterwards — confirm `unchanged: true` for the enriched rows.
