Examples/cbam calculator#570
Conversation
EU CBAM agent that calculates carbon border adjustment costs for importers of iron/steel, aluminium, cement, fertilizers, hydrogen and electricity. Covers applicability check, 50-tonne exemption threshold, cost estimate using EU ETS price, compliance requirements and documentation checklist. Verified locally: 200t aluminium from Turkey = 82,680 EUR CBAM cost. Part of Bindu's trade compliance toolchain.
📝 WalkthroughWalkthroughAdds a CBAM (Carbon Border Adjustment Mechanism) calculator example: env placeholder, comprehensive README, a new agent script with INSTRUCTIONS and OpenRouter-configured Agent, Bindu config and handler, and a CBAM compliance skill YAML. ChangesCBAM Calculator Example Agent

- Around line 166-171: The guard computes query from user_messages[-1] but never
uses it when invoking the agent, so align the inputs: either use the extracted
query when running the agent (pass [ {"role": "user", "content": query} ] or
equivalent to agent.run) or remove the query variable and validate directly
against messages/user_messages; update the code paths around query,
user_messages, messages, and the agent.run call so the same data is validated
and passed to the agent.
In `@pyproject.toml`:
- Line 67: Remove the "duckduckgo-search>=8.1.1" entry from the core
[project.dependencies] block in pyproject.toml and ensure it remains only in the
optional [project.optional-dependencies].agents group; verify the CBAM example
(examples/cbam-calculator/cbam_calculator.py) continues to import only agno,
OpenRouter and python-dotenv (and not DuckDuckGoTools) so runtime installs are
not forced to include duckduckgo-search.

Minor: query is validated but never used.
The non-empty query is computed for the empty-input guard but the agent is run on the full messages list, so the extracted query is otherwise unused. Functionally fine; flagging for clarity since the guard and the run input diverge.
