unknown section '{name}'; valid: {', '.join(_ALL_SECTIONS)}

Error message

unknown section '{name}'; valid: {', '.join(_ALL_SECTIONS)}

What it means

The stock_profile tool resolves a `sections` argument against a fixed set of known section names (_SECTION_MODULES keys). Each requested name is normalized (strip+lowercase) and must match a known section; unknown names raise ValueError listing all valid sections. This prevents loading nonexistent profile sections.

Solutions

1. Read the error message: it enumerates every valid section; use only those names
2. Update the tool package if you expect a section that the installed version doesn't register
3. Remove or correct the offending entry in the sections list

Example fix

# before
tool.execute(symbol="AAPL", sections=["valuaton"])
# after
tool.execute(symbol="AAPL", sections=["valuation"])  # use a name from the error's valid list

from agent.src.tools.stock_profile_tool import _ALL_SECTIONS
sections = [s for s in requested if str(s).strip().lower() in set(_ALL_SECTIONS)]
if not sections:
    sections = list(_ALL_SECTIONS)
tool.execute(symbol=symbol, sections=sections)

def valid_section(name: str) -> bool:
    return str(name).strip().lower() in _ALL_SECTIONS

When it happens

Trigger: Calling stock_profile with sections=["overview", "fundamentals"] where one name isn't in _ALL_SECTIONS; typos like "valuaton"; names not in the module registry despite being mentioned in docs of a different version.

Common situations: Docs/tool-schema drift between versions where a section was renamed or removed; agents hallucinating section names; casing/spelling mistakes (these are auto-lowercased, but wrong words still fail).
