# Luma Participant Check

> Check Luma event guests against X profile, follow, mutual-follow, affiliation, and recent-account-activity requirements. Use when Codex needs to review a Luma event guest table, extract pending guests and X profile links, identify missing/invalid/deleted/protected X accounts, use X relationship lookup to verify whether guests follow the logged-in organizer account, check whether candidates have posted from their own X account within the last month excluding repost-only activity using read-only internal APIs, prioritize mutual follows before followed-by-only candidates, check whether a specific X handle registered and what current Luma status it has, manage X rate limits without causing 429s, and report decline or approval-support candidates without ever performing approve, decline, or other guest write actions.

# Luma Participant Check

## Workflow

Use this skill for Luma events whose approval rules require a valid X profile, following the organizer's X account, and recent activity from the candidate's own X account.

Never approve or decline guests. Never perform Luma or X write actions for this workflow. Produce review lists, verification summaries, and manual-operation batches only.

When supporting manual review in batches, refresh or re-extract the Luma guest table before each new batch. Exclude guests whose current status is already `Not Going`, `Declined`, `Approved`, or `Going`. Only present guests that are still `Pending Approval`.

Before naming the next manual target, re-read Luma and confirm the guest is still `Pending Approval`. For follow-related targets, also re-run X relationship lookup for that specific current target set. Do not name a guest from cached or previous-turn results alone.

Manual review order:

1. First identify guests with no X profile, a non-repairable X profile value, a deleted or nonexistent X account, or a protected account. Report these as the first decline batch.
2. After the user manually declines that batch, refresh Luma and verify those guests moved out of `Pending Approval`.
3. Only then run or report follow checks for the remaining valid public X accounts. Accounts that do not exist cannot follow the organizer, so do not mix missing-account declines with not-following declines.
4. After the user manually handles not-following guests, refresh Luma again.
5. For remaining `Pending Approval` guests with valid public X accounts and `followed_by`, check account activity in strict stages. First identify accounts whose total post count is zero and report only that decline batch.
6. After the user manually declines zero-post accounts, refresh Luma and verify those guests moved out of `Pending Approval`.
7. Only then identify accounts with posts but no non-repost post from the account within the last month. Report that as a separate decline batch.
8. After the user manually handles the no-recent-own-post batch, refresh Luma again.
9. Treat remaining guests as approve candidates only when the account has at least one non-repost post from the account within the last month.
10. For approval support, prioritize mutual follows before followed-by-only accounts. Do not use first-come order as a decision rule unless the user explicitly asks for it.
11. Within each priority group, split or annotate candidates by the user's requested review dimensions, such as plan, affiliation clarity, or role. Keep each table limited to current `Pending Approval` guests unless the user explicitly asks for another status set.

## Required Browser State

Use the user's logged-in Chrome profile when Luma admin access or X login state is required. Confirm the visible profile/session is the user's normal logged-in session before interacting with private admin pages.

Prefer the Luma guest table URL:

```text
https://luma.com/event/manage/guest-table/<event-id>
```

If the user gives the normal guests URL, derive the guest table URL from the event id and open it directly.

## Safety Rules

- Never click or call approve, decline, invite, cancel, delete, update, refund, check-in, message, email, or other guest-modifying actions.
- Do not replay or synthesize Luma requests whose URL, method, body, GraphQL operation, or response semantics indicate a write or mutation.
- Treat the user's manual approve / decline work as external state. Verify it by reading the table after the user says they are done.
- Do not open each X profile in a loop.
- Do not use X search or external search to infer relationships.
- Use X relationship lookup in batches for follow verification.
- Stop immediately and report status if any X request returns HTTP 429.
- For X recent activity checks, do not crawl profile UI. Use read-only internal X APIs only, except for a few exploratory probe requests needed to identify the current internal endpoint shape.
- After internal API shape is confirmed, switch immediately to scripted internal API reads. Do not continue opening or scrolling X profiles one by one.
- Keep request batches small, normally 50 handles per request.
- Do not expose auth cookies, CSRF tokens, bearer tokens, or raw request headers in the final answer.
- Repair obvious X URL typos before marking a row invalid, such as `https:/x.com/<handle>`, `http:/x.com/<handle>`, bare `x.com/<handle>`, or a broken anchor whose visible text still contains `x.com/<handle>`.
- Treat missing, non-repairable malformed, deleted, suspended, and protected X accounts as decline candidates when the event rule requires a public valid X profile.
- Treat accounts without `followed_by` as decline candidates when the rule requires following the organizer account.
- Keep unknowns separate from confirmed decline candidates.

## Luma Extraction

Open the Luma guest table in Chrome. Prefer safe read acceleration from observed Luma network traffic before falling back to DOM scrolling.

Read-only acceleration:

- Inspect Chrome DevTools network requests on the guest table page.
- Prefer already-observed Luma requests that return guest rows, registration answers, status, and profile links.
- Reuse only requests that are clearly read-only. GET requests are usually acceptable. POST requests are acceptable only when the body is clearly a read/query request and does not include mutation-like operation names or action fields.
- Save the read result as JSON and derive pending candidates from the current `status`.
- When parsing Luma `registration_answers`, extract the X handle only from the exact X profile question. Prefer a stable question id from the event, or a label containing `あなたの X のプロフィールリンク`, `X のプロフィールリンク`, `X profile`, or `Twitter profile`.
- Do not infer X handles from arbitrary short answers in other registration questions, such as role, company, LinkedIn, terms, or experience fields.
- Use `scripts/extract-luma-api-candidates.mjs` on saved Luma API JSON when using read-only acceleration.
- If read-only status is ambiguous, do not replay the request. Use the DOM extraction helper instead.
- Never use this acceleration for approve / decline execution.

Run API extraction:

```bash
node /path/to/luma-participant-check/scripts/extract-luma-api-candidates.mjs /path/to/luma-api-response.json
```

If the event's X question id is known, pass it explicitly:

```bash
node /path/to/luma-participant-check/scripts/extract-luma-api-candidates.mjs /path/to/luma-api-response.json --x-question-id n7ka2jlv
```

Spot-check suspicious names and duplicate names against raw `registration_answers` before reporting. Duplicate display names can refer to different guests with different statuses and X handles.

## Identity and Duplicate Handling

Treat display names as labels only, not identities. Always key Luma guests by `api_id` plus normalized X handle when comparing extraction results, manual decline confirmations, activity checks, and approval-support candidates.

- Normalize X handles case-insensitively and strip leading `@`.
- Treat duplicate display names as separate guest records even when the visible name is identical.
- Report duplicate-prone rows as `name @handle status` so the user can distinguish them.
- Do not collapse pending candidates by display name.
- When a row moves between `Pending Approval`, `Approved`, `Declined`, or `Not Going`, verify the specific `api_id` and normalized X handle rather than a same-name row.

## Affiliation Review

Use affiliation review only after valid X-account checks are done and the user asks to split or prioritize remaining candidates by organization. Do not run affiliation review before missing, invalid, deleted, suspended, protected, not-following, zero-post, and no-recent-own-post decline batches when those rules are active.

Extract affiliation from the exact Luma work or school question. Prefer a stable question id from the event, or a label containing `Where do you work or study`, `お勤め先`, or `学校`.

Classify affiliation as clear when it contains a company, school, public institution, organization, or specific self-employment or freelance context. Examples of clear values include a company name, university name, public agency, `フリーランスエンジニア`, and `個人事業主` with concrete client or work context.

Classify affiliation as weak or needing review when it is only a location, generic word, or non-affiliation status. Examples include `東京`, `work`, `Individual`, `現在転職中です`, and broad industry labels like `Digital Consulting Firm` when no actual organization or concrete self-employment identity is given.

Report affiliation splits as tables and keep only current `Pending Approval` rows unless the user explicitly asks for a different status set.

## Specific Handle Status Checks

When the user asks whether a specific X URL or handle registered, is approved, is participating, or canceled, refresh Luma or use a just-refreshed Luma API snapshot, then match by normalized X handle from the exact X-profile answer.

Report a compact table with:

- Luma name
- X link
- plan
- affiliation
- current Luma status

Interpret `Approved` as approved to attend. Interpret `Pending Approval` as not yet approved. Interpret `Declined` as not approved. Interpret `Not Going` or equivalent canceled status as canceled or not attending. Do not infer cancellation from fields such as `has_joined_event: false` or `joined_at: null`; those are not the approval status.

DOM fallback:

Scroll or use the extraction helper until the full table is loaded.

Use `scripts/build-luma-extract-eval.mjs` to generate a Chrome DevTools `evaluate_script` function:

```bash
node /path/to/luma-participant-check/scripts/build-luma-extract-eval.mjs
```

Run the generated function on the Luma guest table page. Save the result as JSON in the working directory.

The extraction helper reads both anchor `href` values and visible link text. This matters because Luma can normalize a typo like `https:/x.com/<handle>` into a broken href while the visible text still contains the intended handle.

From the result, review:

- `pending`: guests with `Pending Approval`
- `candidates`: pending guests with a syntactically valid X handle
- `invalidX`: pending guests with no usable X profile link
- `allRows`: raw extracted rows for spot checks

Spot-check several rows against the visible table before using the result. If counts do not match the Luma UI, continue scrolling and re-run extraction.

Before presenting a new decline or approve support batch, re-run the Luma extraction or directly re-check the specific candidate rows. Remove any candidates that have changed to `Not Going` after the previous manual batch.
If the user asks "next" or "what should I do now", perform this refresh before answering with names. If a previously proposed guest is now `Declined`, `Not Going`, `Approved`, or `Going`, report that status and do not include them in the next action list.

## X Relationship Lookup

Use the logged-in X page for the organizer account. A followers page is a good starting point:

```text
https://x.com/<organizer-handle>/followers
```

Use Chrome DevTools network logs from an existing X request to confirm that authenticated X web requests are working. Do not print sensitive headers to the user.

Prepare a candidates JSON file shaped like:

```json
[
  {"name": "Guest Name", "handle": "guest_handle"}
]
```

Use `scripts/build-x-guest-check-eval.mjs` to generate a Chrome DevTools `evaluate_script` function:

```bash
node /path/to/luma-participant-check/scripts/build-x-guest-check-eval.mjs /path/to/candidates.json
```

Run the generated function on an X page while logged in as the organizer. It performs:

- `friendships/lookup.json` to read `connections`

Do not run bulk `users/lookup.json` by default. A single inactive, deleted, or renamed handle can make a batch return a noisy 404 and hide valid users in the same batch. Use X profile UI checks or targeted single-account read checks only when protected or deleted-account validation is still needed.

Interpret results:

- `connections` contains `followed_by`: the guest follows the organizer
- `connections` does not contain `followed_by`: decline candidate for not following
- no lookup result: unknown, usually missing/deleted/suspended/renamed
- X profile UI says the account does not exist: decline candidate for invalid X profile
- X profile UI says posts are protected: decline candidate for protected account

## X Recent Activity Check

Run this only after the guest has a valid public X account and `followed_by` is confirmed.

Use the logged-in browser profile only as an authenticated context for read-only internal X API requests. Do not inspect candidate timelines by scrolling or opening each X profile. A few probe requests are acceptable to confirm the current internal API endpoint shape; once the shape is understood, use scripted internal API reads and stop UI-based inspection.

Activity requirement:

- The account must have at least one post from the account within the last month.
- Separate decline patterns by stage. Report accounts with `legacy.statuses_count === 0` first, wait for the user to handle that batch, refresh Luma, and only then report accounts that have posts but no qualifying post within the last month.
- Reposts do not count.
- A reply or quote can count only when it includes the candidate's own text and appears on the candidate's account timeline.
- If the visible recent timeline contains only reposts, treat it as no qualifying recent activity.
- If a pinned post is before the cutoff date, do not count it just because it appears at the top of the profile.
- If an article contains a repost marker such as `<name>さんがリポスト`, treat it as a repost even when the candidate handle appears somewhere inside the article text.
- If the visible timeline shows recent reposts but the newest non-repost by the candidate is before the cutoff, treat the account as not approve-ready.
- If the timeline cannot be read confidently because of protected, deleted, suspended, or unavailable account state, keep it out of approve candidates and report it separately.

Observed internal API path:

- Use `UserByScreenName` first to resolve `rest_id`, account protection, and `legacy.statuses_count`.
- Treat `legacy.statuses_count === 0` as no posts.
- Use GraphQL `UserTweets` for timeline reads. In this environment, `UserTweets` returned timeline data while `UserTweetsAndReplies`, `SearchTimeline`, `users/lookup.json`, and `users/show.json` returned 404. Do not use those failed endpoints unless a fresh probe proves they work.
- Request only enough timeline data to answer the activity question, such as `count: 100`.
- Treat reposts as non-qualifying when `legacy.retweeted_status_result` exists or the full text starts with `RT @`.
- Read the author handle from `core.user_results.result.core.screen_name`. Do not rely on `legacy.screen_name`; in observed `UserTweets` responses that field was missing and caused false inactive results.
- Compare tweet `legacy.created_at` against the absolute cutoff timestamp.
- If every checked row becomes inactive, treat that as a parser failure until raw samples prove otherwise. Inspect one raw `UserTweets` sample and fix the parser before reporting names.

Rate-limit handling:

- Track `x-rate-limit-remaining`, `x-rate-limit-limit`, and `x-rate-limit-reset` for every internal X request.
- If `x-rate-limit-remaining` is low, for example 5 or less, stop before hitting 429 and wait until `x-rate-limit-reset`.
- Do not describe this as a 429. Report it as a preemptive stop before rate-limit exhaustion.
- If an actual 429 occurs, stop immediately and report the checked count, saved result file, endpoint, remaining/reset metadata if available, and that no approve or decline action was taken.

Use absolute dates in the working notes and final summary when applying the one-month cutoff. For example, on 2026-07-05, the cutoff is 2026-06-05.

Do not over-fetch timelines. Check only enough internal timeline data to determine whether there is at least one qualifying non-repost post after the cutoff, or that the account has no qualifying visible post in that window. Validate this workflow on a small set of real candidate profiles before changing this section again.

## Reporting

Report concise sections:

- Confirmed decline candidates: no valid X profile
- Confirmed decline candidates: protected X account
- Confirmed decline candidates: not following the organizer
- Confirmed decline candidates: zero X posts
- Not approve-ready: X posts exist, but no qualifying non-repost X post within the last month
- Approval support: mutual follows and followed-by-only candidates
- Affiliation split: clear affiliation vs weak or needs-review affiliation
- Specific handle status: whether a handle registered and its current Luma status
- Unknown: lookup did not return a usable account
- Manual batch verification: which proposed names are now `Not Going`, which remain `Pending Approval`, and which were not found in the current virtual table scan
- Verification: total candidates checked, X request count, whether 429 occurred

State explicitly that no Approve / Decline action was taken.

Avoid long explanations unless the user asks for them.
