Finish

Complete the task with a final answer and save reusable subagents as skills.

Required Parameters

Both answer and subagents are required keys. Omitting either will cause a validation error.

The 4 Valid Patterns

Do NOT mix skill_name and supersedes in the same entry — they are mutually exclusive.

Pattern 1 — New subagents (first time creating)

You created multiple new subagents with create_subagent and want to save them all.

<action>finish</action>
<params>
{"answer": "...", "subagents": [
  {"entry_file": "researcher.py", "description": "..."},
  {"entry_file": "analyzer.py", "description": "..."},
  {"entry_file": "visualizer.py", "description": "..."}
]}
</params>

Pattern 2 — Modified saved skills (small fix via modify_subagent)

You used modify_subagent with skill_name to fix saved skills. Include skill_name so changes are saved back to the original skill directories.

<action>finish</action>
<params>
{"answer": "...", "subagents": [
  {"entry_file": "researcher.py", "description": "...", "skill_name": "researcher"},
  {"entry_file": "analyzer.py", "description": "...", "skill_name": "analyzer"}
]}
</params>

Pattern 3 — New subagents replacing old skills (create_subagent + supersedes)

You created new subagents to replace old broken skills. The old skills will be deleted.

<action>finish</action>
<params>
{"answer": "...", "subagents": [
  {"entry_file": "researcher.py", "description": "...\n**Improved From**: ...", "supersedes": "old_researcher"},
  {"entry_file": "analyzer.py", "description": "..."}
]}
</params>

Pattern 4 — Nothing to save

Use this when: (a) existing saved subagents already solved the problem without any new code or modifications, or (b) the subagents completely failed and contain no useful logic. In all other cases, you MUST save ALL reusable subagents — review every subagent you created in this session and save each one that has value. See Important Notes.

<action>finish</action>
<params>
{"answer": "...", "subagents": []}
</params>

Important Notes

• answer must be brief (1-3 sentences). Large content causes JSON parsing failures.
• entry_file must be the exact .py filename you used in create_subagent.
• Modified saved skills must be listed (Pattern 2), otherwise modifications are discarded.
• skill_name and supersedes are mutually exclusive: use one or the other, never both.
• You MUST save ALL reusable subagents: Before calling finish, review EVERY subagent you created in this session (check all .py files in the workspace). Save each one that has value — do not save only the main one. Even helper subagents or narrowly-focused subagents may be useful for future tasks.
• Specific subagents are also worth saving: even if a subagent targets a narrow domain, save it with a descriptive skill name and description that clearly states its specific scope (e.g., what site/API/topic it handles). Benefits: (1) identical or very similar tasks can directly reuse it; (2) for related tasks, its code serves as a working reference — use view_subagent_code to study its structure, API calls, and workarounds, then create_subagent to build a new one based on it.
• All workspace .py files are copied into each saved skill directory.
