green-code: Plant Trees

Plant trees via Tree-Nation to compensate the user's AI carbon footprint.

Steps

1. Read ~/.claude/plugins/data/green-code/config.json to verify API key and forest_id are set. If not, tell the user to run /green:config first.

2. Read ~/.claude/plugins/data/green-code/usage.json to get the current CO2 accumulation.

3. Determine how many trees to plant:

   • If the user provided a number (e.g., /green:plant 3), use that number.
   • If no number provided, calculate: ceil(accumulated.co2_kg / threshold_co2_kg)
   • If the calculated number is 0, tell the user their footprint is too small to warrant a tree yet, and show the current CO2 level.

4. Confirm with the user before planting: "You're about to plant {N} tree(s) via Tree-Nation to offset {co2} kg of CO2. Proceed?"

4b. Determine the dedication message (attached to each planting and shown on the public Tree-Nation certificate):

• If the user provided a message (e.g., /green:plant 3 "merci pour la forêt"), use it verbatim.
• If no message is provided, leave it empty: the script fills in a default (Compensation {co2} kg CO2 - usage IA Claude Code - {date} / Offsetting {co2} kg CO2 - Claude Code AI usage - {date}).

5. If confirmed, run the planting script (the message is optional; wrap it in quotes):

   "${CLAUDE_PLUGIN_ROOT}/scripts/treenation.sh" plant {N} "{message}"
   

6. Parse the output:

   • If starts with OK: -- success. Show the number of trees planted and certificate URLs.
   • If starts with ERROR: -- show the error and suggest checking the API key.

7. After successful planting, update the accumulated CO2:

   • Subtract N * threshold_co2_kg from accumulated.co2_kg in usage.json
   • Use jq or direct JSON edit

8. Show a summary:

   {N} tree(s) planted via Tree-Nation!
   CO2 offset: {offset} kg
   Total trees planted: {trees.total}
   Certificate(s): {urls}
   

Important

• Always confirm before planting (it costs real money via Tree-Nation credits)
• The script handles logging the planting in usage.json automatically (including the message)
• The message appears on the public certificate, so keep it clean; the default is safe when in doubt
• If the API call fails, do NOT modify usage.json
