This is\n guidance, not a hard rule — the only hard restriction is that `file_edit_*` is locked to the plan file.\n- Don't implement the plan or mutate the tracked source tree (editing project files, installing\n dependencies, running migrations, committing). If the user wants those edits, ask them to switch to\n Exec mode.\n- Mutations that don't touch the tracked source tree are fine when they're implicit to the user's\n request — e.g. deleting or rewriting the plan file, filing a GitHub issue when the user asks, or\n downloading a file so you can analyze it for the plan.\n\n## Investigate only what you need\n\nBefore proposing a plan, figure out what you need to verify and gather that evidence.\n\n- When delegation is available, use Explore sub-agents for repo investigation. In Plan Mode, only\n spawn `agentId: \"explore\"` tasks.\n- Give each Explore task specific deliverables, and parallelize them when that helps.\n- Trust completed Explore reports for repo facts. Do not re-investigate just to second-guess them.\n If something is missing, ambiguous, or conflicting, spawn another focused Explore task.\n- If task delegation is unavailable, do the narrowest read-only investigation yourself.\n- Reserve `file_read` for the plan file itself, user-provided text already in this conversation,\n and that narrow fallback. When reading the plan file, prefer `file_read` over `bash cat` so long\n plans do not get compacted.\n- Wait for any spawned Explore tasks before calling `propose_plan`.\n\n## Write the plan\n\n- Use whatever structure best fits the problem: a few bullets, phases, workstreams, risks, or\n decision points are all fine.\n- Include the context, constraints, evidence, and concrete path forward somewhere in that\n structure.\n- Name the files, symbols, or subsystems that matter, and order the work so an implementer can\n follow it.\n- Keep uncertainty brief and local to the relevant step. Resolve it yourself when you can: if you\n have a reasonable default or recommendation, adopt it and note the assumption rather than asking.\n- Include small code snippets only when they materially reduce ambiguity.\n- Put long rationale or background into `
/` blocks.\n\n## Questions and handoff\n\n- Use `ask_user_question` only for genuinely balanced decisions that depend on context,\n preferences, or information the user has not provided — never to confirm a choice you would\n recommend anyway. If you already have a recommended option, the question is pointless: proceed\n with it and state the assumption. When you do ask, keep the options genuinely open rather than\n steering toward one \"recommended\" choice.\n- When clarification is genuinely needed, prefer `ask_user_question` over asking in chat or adding\n an \"Open Questions\" section to the plan.\n- Ask up to 4 questions at a time (2–4 options each; \"Other\" remains available for free-form\n input).\n- After you get answers, update the plan and then call `propose_plan` when it is ready for review.\n- After calling `propose_plan`, do not paste the plan into chat or mention the plan file path.\n\nWorkspace-specific runtime instructions (plan file path, edit restrictions, nesting warnings) are\nprovided separately.\n", }; diff --git a/src/node/services/agentDefinitions/resolveToolPolicy.test.ts b/src/node/services/agentDefinitions/resolveToolPolicy.test.ts index b9de20fd5c..e96313635b 100644 --- a/src/node/services/agentDefinitions/resolveToolPolicy.test.ts +++ b/src/node/services/agentDefinitions/resolveToolPolicy.test.ts @@ -107,7 +107,7 @@ describe("resolveToolPolicyForAgent", () => { { regex_match: ".*", action: "disable" }, { regex_match: "ask_user_question", action: "disable" }, { regex_match: "propose_plan", action: "disable" }, - { regex_match: "agent_report", action: "require" }, + { regex_match: "agent_report", action: "enable" }, advisorDisabledRule, ]); }); @@ -126,7 +126,7 @@ describe("resolveToolPolicyForAgent", () => { { regex_match: "file_read", action: "enable" }, { regex_match: "ask_user_question", action: "disable" }, { regex_match: "propose_plan", action: "disable" }, - { regex_match: "agent_report", action: "require" }, + { regex_match: "agent_report", action: "enable" }, advisorDisabledRule, ]); }); @@ -187,7 +187,7 @@ describe("resolveToolPolicyForAgent", () => { { regex_match: "task_.*", action: "disable" }, { regex_match: "ask_user_question", action: "disable" }, { regex_match: "propose_plan", action: "disable" }, - { regex_match: "agent_report", action: "require" }, + { regex_match: "agent_report", action: "enable" }, advisorDisabledRule, ]); }); diff --git a/src/node/services/agentDefinitions/resolveToolPolicy.ts b/src/node/services/agentDefinitions/resolveToolPolicy.ts index ca07fb1944..6cba5f339d 100644 --- a/src/node/services/agentDefinitions/resolveToolPolicy.ts +++ b/src/node/services/agentDefinitions/resolveToolPolicy.ts @@ -137,9 +137,10 @@ export function resolveToolPolicyForAgent(options: ResolveToolPolicyOptions): To runtimePolicy.push({ regex_match: "propose_plan", action: "require" }); runtimePolicy.push({ regex_match: "agent_report", action: "disable" }); } else { - // Non-plan subagents should complete through agent_report. + // Non-plan subagents complete with their final assistant message. agent_report remains + // available for optional incremental updates that wake the parent while work continues. runtimePolicy.push({ regex_match: "propose_plan", action: "disable" }); - runtimePolicy.push({ regex_match: "agent_report", action: "require" }); + runtimePolicy.push({ regex_match: "agent_report", action: "enable" }); } } diff --git a/src/node/services/agentSkills/builtInSkillContent.generated.ts b/src/node/services/agentSkills/builtInSkillContent.generated.ts index 85452b2108..de31ae1c8d 100644 --- a/src/node/services/agentSkills/builtInSkillContent.generated.ts +++ b/src/node/services/agentSkills/builtInSkillContent.generated.ts @@ -84,9 +84,9 @@ export const BUILTIN_SKILL_FILES: Record> = { "Instructions:", "1.
