fix(0.42.0): workspace discoverability gap for data-app local dev (#304)

[padak]

Summary

Closes #304 (David Ešner). Four overlapping signals around finding a Query-Service-compatible workspace for data-app local dev were either invisible or actively misleading. This PR closes all four:

• workspace list / workspace detail get --branch + the same Info: Using production branch for read (active dev branch X ignored; pass --branch X to override) banner as storage buckets / config list. Before: silently scoped to the pinned dev branch (carried over across sessions) → different workspace set than the same alias one shell ago.
• Every workspace entry now exposes login_type, read_only, qs_compatible, database, warehouse. Storage API has always returned connection.loginType + readOnlyStorageAccess; kbagent simply discarded them. Human mode adds Login Type / RO / QS columns.
• New workspace list --qs-compatible filter pre-selects RO + whitelisted-loginType workspaces (canonical data-app shape). Whitelist = snowflake-service-keypair + snowflake-person-sso; conservative (false negatives over false positives) because snowflake-legacy-service works on connection.keboola.com but failed on GCP us-east4 in the original incident.
• config detail --component-id keboola.sandboxes --config-id <ID> now appends a sandbox_annotation block with sandbox_service_id (the misleading parameters.id) AND storage_workspace_id (the actual Storage workspace ID resolved via workspace list). Single-config mode only to avoid N+1.

Empirical verification on /tmp/kbagent (padak-2-0 + padak)

# 1. Pinned to dev branch 1297900, NO --branch passed → production used, banner shown:
$ kbagent workspace list --project padak-2-0
Info: Using production branch for read (active dev branch '1297900' ignored;
pass --branch 1297900 to override)
(table with Login Type / RO / QS columns)

# 2. --qs-compatible filter on padak (22 workspaces, 4 distinct loginTypes):
$ kbagent --json workspace list --project padak --qs-compatible | jq '.data.workspaces | length'
2   # ← only snowflake-service-keypair + snowflake-person-sso pass
# Without filter: 22 workspaces (19 default, 1 each of the 3 snowflake-* variants)

# 3. Sandbox config annotation:
$ kbagent --json config detail --project padak --component-id keboola.sandboxes --config-id 01kjwb4g72nr3d3yvvzaffd2vh \
    | jq '.data.sandbox_annotation'
{
  "sandbox_service_id": null,
  "storage_workspace_id": 2950518214,
  "note": "`parameters.id` in a keboola.sandboxes config is the sandbox-service internal ID, NOT the Storage workspace ID. Use `storage_workspace_id` with `kbagent workspace detail --workspace-id ...`."
}

Test plan

• make lint clean
• make format-check clean
• make changelog-check clean
• Full test suite: 3206 passed, 86 skipped (server-extras tests require the optional [server] extras and are not installed in this venv -- same baseline as before)
• 14 new tests added covering all four fixes (5 in test_workspace_cli.py, 7 in test_workspace_service.py, 3 in test_cli.py::TestConfigDetail)
• Empirical bug reproduction in /tmp/kbagent against 6 real projects
• Empirical fix verification in same env: banner appears, --branch opt-in works, --qs-compatible filters correctly, sandbox annotation resolves the real workspace ID

Docs synchronised (per CLAUDE.md §17 silent-drift surfaces)

• CLAUDE.md ## All CLI Commands -- new flags on workspace list / workspace detail
• src/keboola_agent_cli/commands/context.py (AGENT_CONTEXT) -- workspace + config detail sections
• plugins/kbagent/agents/keboola-expert.md -- VERSION GATE entry for 0.42.0+; 2 new Tool Selection Matrix rows (data-app workspace picking + sandbox config resolution)
• plugins/kbagent/skills/kbagent/references/commands-reference.md -- workspace section
• plugins/kbagent/skills/kbagent/references/gotchas.md -- 2 new (since v0.42.0) sections
• src/keboola_agent_cli/changelog.py -- 0.42.0 entry
• pyproject.toml + plugin.json + marketplace.json -- version bumped via make version-sync

Review of #311 — fix(0.42.0): workspace discoverability gap for data-app local dev (#304)

are advisory; the human author retains every veto. CI-coverable issues
(lint, format, tests) are confirmed via make check, not duplicated here.

Summary

This PR closes four overlapping discoverability gaps that cost David Ešner
~30 min of trial-and-error when onboarding a Streamlit data app: the
workspace list / workspace detail branch-scoping surprise, missing
login_type / read_only / qs_compatible fields, the new
--qs-compatible filter, and the misleading parameters.id annotation in
config detail --component-id keboola.sandboxes. The implementation is
clean: correct 3-layer split, constants in constants.py, strong test
coverage (14 new unit tests, all passing), and every Plugin synchronization
map surface was updated. One BLOCKING issue prevents merge: the 9 lines
added to keboola-expert.md pushed the file from 59780 to 61528 bytes,
exceeding the 60000-byte budget enforced by tests/test_agent_prompt.py::TestPilotAgentFile::test_agent_prompt_under_token_budget.
This test is part of make check but the worktree's missing optional deps
cause the server-extras tests to fail before it runs, masking the failure
unless you run the full suite via the main repo venv.

Verdict: REQUEST CHANGES (one blocking finding).

Blocking findings

[B-1] plugins/kbagent/agents/keboola-expert.md — agent prompt exceeds 60000-byte budget

The nine lines added to the VERSION GATE entry and two new Tool Selection
Matrix rows pushed keboola-expert.md from 59780 bytes (on main) to
61528 bytes (+1748 bytes over the 60000-byte hard ceiling). This causes
tests/test_agent_prompt.py::TestPilotAgentFile::test_agent_prompt_under_token_budget
to fail with:

AssertionError: Agent prompt is 61528 bytes (~15382 tokens);
budget is 60000 bytes. Trim or split into specialists.

The test is part of the normal pytest suite and should be caught by make check, but the worktree environment lacks the optional [server] extras,
so collection errors in the server tests cause the run to abort before
reaching test_agent_prompt.py -- masking the failure.

Fix: trim the two new Tool Selection Matrix rows (currently at keboola-expert.md
§2, the Find a Query-Service-compatible workspace and Resolve a keboola.sandboxes config rows) to fit within the budget. The detailed prose can move to
plugins/kbagent/skills/kbagent/references/gotchas.md (already updated in
this PR) and the matrix rows can be shortened to one-liners referencing the
gotcha. Target: ≤59900 bytes total.

Non-blocking findings

[NB-1] src/keboola_agent_cli/server/routers/workspaces.py:74,96 — REST API does not expose new branch / qs-compatible params

GET /workspaces (line 74) calls list_workspaces(aliases=project, orphaned_only=orphaned) without branch_id or qs_compatible_only. GET /workspaces/{project}/{workspace_id} (line 96) calls get_workspace(alias=project, workspace_id=workspace_id) without branch_id. Per CONTRIBUTING.md > "HTTP API endpoint": "every command in a group has a matching endpoint in that group's router (1:1 convention)". External consumers of kbagent serve (Web UI, scheduled agents, Streamlit dashboards) get the pre-0.42.0 behavior -- no QS field filtering, no branch scoping -- until the router is updated.

Fix: add branch: int | None = Query(None) and qs_compatible: bool = Query(False) params to list_workspaces, and branch: int | None = Query(None) to detail. Pass through to the service layer. The service already validates multi-alias + branch_id combinations, so the router needs no extra guard.

[NB-2] tests/test_e2e.py — no E2E coverage for new --branch, --qs-compatible, or sandbox_annotation

CONTRIBUTING.md § "E2E tests (mandatory!)": "every new CLI command MUST have a corresponding E2E test". The new flags (workspace list --branch, workspace list --qs-compatible, workspace detail --branch, config detail --component-id keboola.sandboxes with sandbox_annotation) are new flag-level behaviors on existing commands and are not covered by any test in test_e2e.py or test_e2e_lineage_deep.py. The empirical verification in the PR description confirms the behavior worked manually but the E2E suite does not lock it in.

This is NON-BLOCKING per the same section: "environmental constraints can defer one cycle" -- the make test-e2e environment requires E2E_API_TOKEN + E2E_URL. However, deferring means the behavior is unprotected against regression for the lifetime of the gap. Recommend adding E2E coverage in the next release cycle.

Nits

• [NIT-1] src/keboola_agent_cli/commands/config.py:351-355 — the multi-line note string assembled inside the sandbox_annotation dict is a candidate for a named constant in constants.py (e.g. SANDBOX_ANNOTATION_NOTE). Not a problem today (it is only referenced in one place), but if the note text ever needs updating it will be easy to miss. Inline string is acceptable given the single usage.

Delta Review of #311 — fix(0.42.0): workspace discoverability gap for data-app local dev (#304)

Delta pass after follow-up commit 12e5b6a ("fix(0.42.0): address PR #311 review findings"). Checking resolution of prior B-1, NB-1, NB-2, NIT-1.

Summary

The follow-up commit fully resolves all findings from the first review pass. The blocking byte-budget violation (keboola-expert.md at 61528 bytes) is fixed: the file now stands at 59973 bytes, passing test_agent_prompt_under_token_budget (budget = 60000). The REST router (server/routers/workspaces.py) now exposes branch and qs_compatible query parameters on both GET "" (list) and GET "/{project}/{workspace_id}" (detail), with correct validation parity to the CLI. An E2E test class TestE2EWorkspaceDiscoverability with a 5-step test_issue_304_discoverability_roundtrip covers all four PR behaviors against a real API. The router summary= annotations (NIT) are also present. Full unit suite: 3206 passed, 9 skipped (server-extras excluded from this venv, same baseline as before). All 42 test_agent_prompt.py checks pass.

Verdict: APPROVE (zero blocking, zero non-blocking findings).

Nits

• [NIT-1] plugins/kbagent/agents/keboola-expert.md — byte margin is 27 bytes (59973 / 60000). Any future addition to the VERSION GATE or Tool Selection Matrix will breach the budget. Consider extracting the workspace-discoverability note to gotchas.md (where the prose already lives) and referencing it with a one-liner in keboola-expert.md, freeing ~200 bytes of headroom.
