## Runtime rules for generated code
- No imports.
- Helper functions are already in scope.
- All helper/API calls are async: always use `await`.
- `max_calls` is the total external-call budget for the whole generated program, not a generic helper argument.
- The outer wrapper is an exact contract. Use this exact skeleton and only change the body:
```py
async def solve(query, max_calls):
    ...

await solve(query, max_calls)
```
- Do **not** modify that wrapper shape:
  - no `async def solve(query, max_calls=100):`
  - no `async def solve(q, max_calls):`
  - no `async def solve(query, *, max_calls):`
  - no `await solve(query, max_calls or 100)`
  - no `await solve(query, max_calls if ... else ...)`
  - no `budget = max_calls` followed by `await solve(query, budget)`
- The runtime supplies `max_calls`; generated code must not invent defaults or fallbacks for it.
- At the tool-call layer, normally omit `max_calls` and `timeout_sec` so the runtime defaults apply. Do **not** invent small explicit tool-call budgets like `10` or `20` for ordinary requests.
- Use helper functions first. Use raw `call_api('/api/...')` only if no helper fits.
- `call_api` must receive a raw path starting with `/api/...`; never call helper names through `call_api`.
- Raw `call_api(...)` endpoints must match the runtime allowlist exactly. Do **not** invent hyphen/underscore variants or guessed path shapes.
- `call_api(...)` returns `{ok, status, url, data, error}`. Always check `resp["ok"]` before reading `resp["data"]`. Do not read `resp["items"]` or `resp["meta"]` directly from `call_api(...)`.
- `call_api(...)` only accepts `endpoint`, `params`, `method`, and `json_body`. Do not guess extra kwargs.
- Use `call_api(...)` only for endpoint families that do not already have a helper, such as `/api/daily_papers` or tag metadata endpoints.
- For daily papers, use the exact raw endpoint string `/api/daily_papers` (underscore), **not** `/api/daily-papers`.
- For questions about supported helpers, fields, limits, raw API affordances, or runtime capabilities, use `hf_runtime_capabilities(...)` instead of hand-authoring a static answer from memory.
- Keep final displayed results compact, but do not artificially shrink intermediate helper coverage unless the user explicitly asked for a sample.
- Prefer canonical snake_case keys in generated code and in JSON output.
- When returning a structured dict that includes your own coverage metadata, use the exact top-level keys `results` and `coverage` unless the user explicitly requested different key names.
- Omit unavailable optional fields instead of emitting `null` placeholders unless the user explicitly asked for a fixed schema with nulls.
- If the user asks for specific fields or says "return only", return exactly that final shape from `solve(...)`.
- For current-user prompts (`my`, `me`), use helpers with `username=None` first. Only ask for identity if that fails.
- When a current-user helper response has `ok=false`, return that helper response directly instead of flattening it into an empty result.

## Common helper signature traps
These are high-priority rules. Do not guess helper arguments.

- `hf_repo_search(...)` uses `limit`, **not** `return_limit`, and does **not** accept `count_only`.
- `hf_trending(...)` uses `limit`, **not** `return_limit`.
- `hf_repo_discussions(...)` uses `limit`, **not** `return_limit`.
- `hf_user_graph(...)`, `hf_user_likes(...)`, `hf_org_members(...)`, `hf_recent_activity(...)`, and `hf_collection_items(...)` use `return_limit`.
- For "how many models/datasets/spaces does org/user X have?" prefer `hf_org_overview(...)` or `hf_user_summary(...)["item"]["overview"]` instead of trying to count with `hf_repo_search(...)`.
- Never invent helper args such as `count_only=True` for helpers that do not document it.

## Helper result shape
All helpers return:
```py
{
  "ok": bool,
  "item": dict | None,
  "items": list[dict],
  "meta": dict,
  "error": str | None,
}
```

Rules:
- `items` is the canonical list field.
- `item` is only a singleton convenience.
- `meta` contains helper-owned execution, coverage, and limit information.
- For metadata-oriented prompts, return the relevant `meta` fields instead of inferring coverage from list length alone.
- For bounded list/sample helpers in raw mode, returning the helper envelope directly preserves helper-owned `meta` fields.

## Routing guide
### Runtime self-description
- Supported fields / helper signatures / limits / raw API affordances → `hf_runtime_capabilities(...)`

### Repo questions
- Exact `owner/name` details → `hf_repo_details(repo_type="auto", ...)`
- Search/discovery/list/top repos → `hf_repo_search(...)`
- True trending requests → `hf_trending(...)`
- Repo discussions → `hf_repo_discussions(...)`
- Specific discussion details / latest comment text → `hf_repo_discussion_details(...)`
- Users who liked a specific repo → `hf_repo_likers(...)`

### User questions
- Profile / overview / "tell me about user X" → `hf_user_summary(...)`
- Followers / following / graph samples → `hf_user_graph(...)`
- Repos a user liked → `hf_user_likes(...)`
- Recent actions / activity feed → `hf_recent_activity(feed_type="user", entity=...)`

### Organization questions
- Organization details and counts → `hf_org_overview(...)`
- Organization members → `hf_org_members(...)`
- Organization repos → `hf_repo_search(author="<org>", repo_types=[...])`
- Organization or user collections → `hf_collections_search(owner="<org-or-user>", ...)`
- Repos inside a known collection → `hf_collection_items(collection_id=...)`

### Direction reminders
- `hf_user_likes(...)` = **user → repos**
- `hf_repo_likers(...)` = **repo → users**
- `hf_user_graph(...)` = **user/org → followers/following**
- If the author/org is already known, start with `hf_repo_search(author=...)` instead of semantic search.
- For "most popular repo a user liked", use `hf_user_likes(sort="repoLikes" | "repoDownloads", ranking_window=40)` instead of fetching recent likes and re-ranking locally.

## Common row keys
Use these canonical keys unless the user explicitly wants different names.

- Repo rows: `repo_id`, `repo_type`, `title`, `author`, `likes`, `downloads`, `created_at`, `last_modified`, `pipeline_tag`, `library_name`, `repo_url`, `tags`
- User graph/member rows: `username`, `fullname`, `isPro`, `role`, `type`
- Activity rows: `event_type`, `repo_id`, `repo_type`, `timestamp`
- Collection rows: `collection_id`, `slug`, `title`, `owner`, `owner_type`, `description`, `last_updated`, `item_count`
- `hf_user_summary(...)["item"]["overview"]`: `username`, `fullname`, `bio`, `websiteUrl`, `twitter`, `github`, `linkedin`, `bluesky`, `followers`, `following`, `likes`, `isPro`

Common aliases in `fields=[...]` are tolerated by the runtime, but prefer the canonical names above in generated code.

## Common repo fields
- `repo_id`
- `repo_type`
- `title`
- `author`
- `likes`
- `downloads`
- `created_at`
- `last_modified`
- `pipeline_tag`
- `repo_url`
- model: `library_name`
- dataset: `description`, `paperswithcode_id`
- space: `sdk`, `models`, `datasets`, `subdomain`

Common aliases tolerated in `fields=[...]`:
- `repoId` → `repo_id`
- `repoType` → `repo_type`
- `repoUrl` → `repo_url`
- `createdAt` → `created_at`
- `lastModified` → `last_modified`

## Common collection fields
- `collection_id`
- `slug`
- `title`
- `owner`
- `owner_type`
- `description`
- `last_updated`
- `item_count`

Common aliases tolerated in `fields=[...]`:
- `collectionId` → `collection_id`
- `lastUpdated` → `last_updated`
- `ownerType` → `owner_type`
- `itemCount` → `item_count`
- `author` → `owner`

## High-signal usage notes
- `hf_repo_search(...)` defaults to models if no repo type is specified. For prompts like "what repos does <author/org> have", search across `repo_types=["model", "dataset", "space"]` unless the user asked for one type.
- `hf_trending(...)` returns the Hub's ordered trending list. Use `trending_rank` / ordering, not a fabricated numeric trending score.
- If the user explicitly asks for trending scores, say the upstream endpoint does not expose them and return the ordered repos instead.
- `hf_user_summary(...)` is the fastest way to answer common profile prompts. Read profile/social fields from `summary["item"]["overview"]`.
- For "how many models/datasets/spaces does user/org X have?" prompts, prefer the overview helpers (`hf_user_summary(...)["item"]["overview"]` or `hf_org_overview(...)`) over `hf_repo_search(..., limit=1)` or invented `count_only` args.
- Use `hf_whoami()` when you need the explicit current username for joins, comparisons, or output labeling.
- For overlap/comparison/ranking tasks, fetch a broad enough working set first and compute locally in code.
- Avoid per-row hydration calls unless you truly need fields that are not already present in the current helper response.
- For prompts that ask for both a sample and metadata, keep the sample compact and surface helper-owned `meta` fields explicitly.
- For follower/member social-link lookups, first fetch usernames with `hf_user_graph(...)` or `hf_org_members(...)`, then fetch profile/social data with `hf_user_summary(username=...)`.
- For fan-out tasks that require one helper call per follower/member/liker/repo/user, prefer bounded seed sets **by default** so ordinary requests stay fast and predictable.
- If the user explicitly asks for exhaustive coverage (`all`, `scan all`, `entire`, `not just the first N`, `ensure more than the first 20`, etc.), do **not** silently cap the seed at a small sample such as 20 or 50.
- For those explicit exhaustive requests, attempt a substantially broader seed scan first when the runtime budget permits.
- For explicit exhaustive follower/member scans, prefer omitting `return_limit` or using a value large enough to cover the expected total. Do **not** choose arbitrary small caps like 50 or 100 if that would obviously prevent an exhaustive answer.
- If the prompt says both `scan all` and `more than the first 20`, the `scan all` requirement wins. Do **not** satisfy that request with a bare sample of 50 unless you also mark the result as partial.
- If exhaustive coverage is still not feasible within `max_calls` or timeout, say so clearly and return an explicit partial result with coverage metadata instead of presenting a bounded sample as if it were complete.
- When you return a composed partial result, use the exact top-level keys `results` and `coverage` unless the user explicitly asked for a different schema. Do **not** rename `results` to `items`, `rows`, `liked_models`, or similar.
- Do **not** use your own top-level transport wrapper named `meta` in raw mode; runtime already owns the outer `meta`.
- Good coverage fields for partial fan-out results include: `partial`, `reason`, `seed_limit`, `seed_processed`, `seed_total`, `seed_more_available`, `per_entity_limit`, and `next_request_hint`.
- If the user did not explicitly require exhaustiveness, a clear partial result with coverage metadata is better than failing with `Max API calls exceeded`.
- If the user **did** explicitly require exhaustiveness and you cannot complete it, do not imply success. Report that the result is partial and include the relevant coverage/limit fields.
- For explicit exhaustive follower/member prompts, if `meta.more_available` is true or `seed_processed < seed_total`, the final output must not be a bare list that looks complete. Include explicit partial/coverage information.
- Use `hf_recent_activity(...)` for activity feeds instead of raw `call_api('/api/recent-activity', ...)`.
- Use `hf_repo_search(author=..., repo_type="space", ...)` for Spaces by author; there is no separate spaces-by-author helper.
- Use `hf_collections_search(owner=...)` for "what collections does this org/user have?" prompts.
- `hf_collections_search(...)` is for finding/listing collections. It returns collection rows plus `item_count`, not the full repo rows inside each collection.
- Use `hf_collection_items(collection_id=...)` for "what repos/models/datasets/spaces are in this collection?" prompts.
- Do **not** guess raw collection item endpoints such as `/api/collections/.../items`.
