The pipeline was emitting hundreds of errors:
'Invalid number of return arguments after parsing column name: Date'
Root cause: after _clean_dataframe() lowercases all columns, stockstats.wrap()
promotes 'date' to the DataFrame index. Subsequent df['Date'] access caused
stockstats to try parsing 'Date' as a technical indicator name.
- stockstats_utils.py + y_finance.py: use df.index.strftime() instead of
df['Date'] after wrap()
- Eliminates duplicated 30-line download+cache boilerplate in two places
- Cache filename is always derived from today's date — hardcoded stale date
'2015-01-01-2025-03-25' in local mode is gone
- Corruption/truncation detection: files <50 rows or unparseable are deleted
and re-fetched rather than silently returning bad data
- Drops on_bad_lines='skip' — malformed CSVs now raise instead of silently
dropping rows that would distort indicator calculations
- Defined in stockstats_utils.py; raised instead of print()+return ''
- get_stockstats_indicator now raises YFinanceError on failure so errors
surface to callers rather than delivering empty strings to LLM agents
- interface.py route_to_vendor now catches YFinanceError alongside
AlphaVantageError and FinnhubError — failures appear in observability
telemetry and can trigger vendor fallback
- _filter_csv_by_date_range: replaced df.columns[0] positional assumption
with explicit search for 'time'/'timestamp'/'date' column
- ValueError re-raised (not swallowed) so bad API response shape is visible
- Replaced all print() calls in changed files with logging.getLogger()
- Added logging import + logger to alpha_vantage_common
- tests/unit/test_incident_fixes.py: 12 new unit tests covering all fixes
(dynamic cache filename, corruption re-fetch, YFinanceError propagation,
explicit column lookup, empty download raises)
- tests/integration/test_stockstats_live.py: 11 live tests against real
yfinance API (all major indicators, weekend N/A, regression guard)
- All 70 tests pass (59 unit + 11 live integration)
Implement comprehensive unit tests for the `_safe_fmt` utility function
to ensure robust handling of numeric formatting and edge cases.
- Test None values and custom fallbacks
- Test various numeric types (int, float, string)
- Test custom format strings
- Test error handling for invalid types

- Use `--file` instead of `--text` for adding sources to avoid ARG_MAX issues and argument injection.
- Add `--` separator to prevent positional arguments from being misinterpreted as flags.
- Reorder arguments to place options before positional ones.
- Update unit tests and add new security-focused tests.

- New tradingagents/api_usage.py: Pre-run estimation of API calls per vendor
for analyze, scan, and pipeline commands. Includes Alpha Vantage tier
assessment (free: 25/day vs premium: 75/min).
- New CLI command: `estimate-api [analyze|scan|pipeline|all]`
- Enhanced observability: RunLogger.summary() now includes vendor_methods
breakdown (vendor → method → call count)
- Enhanced CLI output: All 3 command summaries (analyze, scan, pipeline)
now show per-vendor breakdown and Alpha Vantage assessment after runs
- 32 new tests in tests/unit/test_api_usage.py

- Create docs/FINANCIAL_TOOLS_ANALYSIS.md with comprehensive 4-point analysis:
1. Implementation accuracy review for all indicators and metrics
2. Library assessment (stockstats vs TA-Lib vs pandas-ta)
3. Alpha Vantage debate (local calc vs API-fetched)
4. Data flow & API mapping for every financial tool
- Fix off-by-one in ttm_analysis.py: YoY revenue used quarterly[-4]
(3 quarters back) instead of quarterly[-5] (4 quarters = 1 year back)
- Add test_revenue_yoy_is_four_quarters_back test to validate the fix

- Added edge case test for `_find_col` in `tests/unit/test_ttm_analysis.py` (from PR #56).
- Enhanced `_clean_dataframe` in `tradingagents/dataflows/stockstats_utils.py` to parse dates, drop invalid rows, fill price gaps, and lowercase columns (combining PRs #58 and #60).
- Expanded the test suite in `tests/unit/test_stockstats_utils.py` to cover the new `_clean_dataframe` functionality.

- Replaced potentially unsafe or missing tool call parsing logic with `ast.literal_eval` in `cli/main.py`.
- Created a new `parse_tool_call` helper to handle fallback parsing for LLM tool calls formatted as strings.
- Added comprehensive unit tests in `tests/unit/test_cli_main_tools.py` verifying behavior for valid strings, `ValueError`, `SyntaxError`, dicts, and objects.

Extracted the API request logic in `finnhub_news.py` to a private `_fetch_company_news_data` helper to properly catch `Exception` and return an empty list without violating the `str` return type of the main `get_company_news` function. Explicitly allows `ThirdPartyTimeoutError` to propagate to preserve timeout behavior.
Added corresponding tests to mock generic API exceptions and invalid response types. Retained the test verifying fallback behavior for invalid numeric values within `get_insider_transactions`.

- Fixed `_signal_vix_trend` to correctly return neutral for insufficient history (`< 21`).
- Added `test_short_history_is_neutral` to `TestSignalVixTrend`.
- Extended coverage for short history and edge cases in `TestSignalCreditSpread`, `TestSignalYieldCurve`, `TestSignalMarketBreadth`, and `TestSignalSectorRotation`.

Added tests to verify the dataframe cleaning logic in stockstats_utils.
Tests cover lowercasing of columns, handling non-string columns, and ensuring original dataframe is not mutated.

Removed re-exported tool imports from `tradingagents/agents/utils/agent_utils.py` to declutter the file and prevent unnecessary dependency loading. Updated all downstream modules (tests, analysts, scanners, and the trading graph) to import the required tools directly from their respective source files in `tradingagents/agents/utils/`.

Added `TestFmtPct` class to `tests/unit/test_macro_regime.py` to test the `_fmt_pct` function from `tradingagents.dataflows.macro_regime`.
The test covers `None`, positive, negative, and zero values.
Also updated `_fmt_pct` implementation to match the requested `+.1f` formatting.
