Two analyst-UX papercuts surfaced by the v0.53.4 onboarding smoke test.
1) /api/query remote_estimate_failed hint now branches on the BigQuery
error class instead of always claiming a column doesn't exist. The
previous hardcoded "Most often this means a column referenced …
doesn't exist" misled analysts whenever BigQuery actually rejected
on syntax — concretely, `SELECT COUNT(*) AS rows FROM …` fails with
`Syntax error: Unexpected keyword ROWS at [1:20]` (`rows` is a BQ
reserved word) and the hint pointed at non-existent columns.
New _hint_for_bq_bad_request() helper dispatches:
- "Syntax error" / "Unexpected keyword" → reserved-keyword alias hint
with `AS row_count` workaround
- "Unrecognized name" / "not found inside" → `agnes schema <id>`
- "Table not found" → `agnes catalog`
- fallback → enumerate all three
4 unit tests in TestHintForBqBadRequest pin each branch. Existing
guardrail tests (test_fallback_fails_fast_on_pure_duckdb_syntax,
test_remote_estimate_failed_surfaces_first_error_when_attempts_differ)
continue to pass — both hint substrings they assert on still appear in
the relevant branches.
2) `agnes catalog` replaces the FLAVOR column with ENTITY. FLAVOR
rendered t['sql_flavor'] which duplicated SOURCE for any catalog
dominated by one source type — analysts saw `SOURCE=bigquery
FLAVOR=bigquery` on every row. ENTITY instead surfaces the upstream
BigQuery entity_type (BASE TABLE / VIEW / MATERIALIZED_VIEW) for
remote rows; non-remote rows render `-`. The distinction matters
operationally: views don't support predicate pushdown, so `agnes
query --remote` against a view trips the cost guardrail where the
same query against a BASE TABLE pushes down cleanly. The
entity_type field has been in the v2 catalog response since 0.51.0;
this PR just stops hiding it behind a column header that conveyed
no information.
JSON output (`agnes catalog --json`) is unchanged — only the human-
readable column changed. No DB migration; no API change.
Verified: 4161 tests pass locally; 25 in test_api_query_guardrail.py
green; the 4 new TestHintForBqBadRequest cases pin each branch.
Bring admin UI, audit-log messages, code comments, and analyst-facing
skill docs in line with the post-bootstrap CLI surface (`agnes pull`,
`agnes push`, `agnes init`, `agnes snapshot create`). The legacy
`_LEGACY_STRINGS` detection tuple in `app/api/claude_md.py` and the hook
upgrade markers in `cli/lib/hooks.py` are intentionally left as-is —
they exist precisely to flag pre-rewrite content for re-authoring.
Strip "(folded from `da metrics list`)" / "(lifted from `da metrics
show`)" / "Replaces the old `da analyst status`" docstring noise — the
rename history is in CHANGELOG.md, not in module docstrings.
Replaces the BigQuery wrap-view pattern with a discovery + scoped-fetch toolkit driven by the analyst's Claude session. Adds /api/v2/{catalog,schema,sample,scan,scan/estimate}, da catalog/schema/describe/fetch/snapshot/disk-info CLI commands, sqlglot-backed WHERE validator, process-local quota tracker, agent rails skill (cli/skills/agnes-data-querying.md). BREAKING: BQ wrap views off by default — set data_source.bigquery.legacy_wrap_views=true for one cycle. Backward-compat field_validator on primary_key. Catalog cache now matches documented 300s TTL with RBAC fresh per request. Cuts release v0.14.0.
