-# Research Plan: [topic]
 
-## Questions
+## Step 1: Plan
-1. ...
 
-## Strategy
+Create `outputs/.plans/<slug>.md` immediately. The plan must include:
-- Researcher allocations and dimensions
+- Key questions
-- Expected rounds
+- Evidence needed
+- Scale decision
+- Task ledger
+- Verification log
+- Decision log
 
-## Acceptance Criteria
+Make the scale decision before assigning owners in the plan. If the topic is a narrow "what is X" explainer, the plan must use lead-owned direct search tasks only; do not allocate researcher subagents in the task ledger.
-- [ ] All key questions answered with ≥2 independent sources
-- [ ] Contradictions identified and addressed
-- [ ] No single-source claims on critical findings
 
-## Task Ledger
+Also save the plan with `memory_remember` using key `deepresearch.<slug>.plan` if that tool is available. If it is not available, continue without it.
-| ID | Owner | Task | Status | Output |
-|---|---|---|---|---|
-| T1 | lead / researcher | ... | todo | ... |
 
-## Verification Log
+After writing the plan, continue immediately. Do not pause for approval.
-| Item | Method | Status | Evidence |
-|---|---|---|---|
-| Critical claim / computation / figure | source cross-read / rerun / direct fetch / code check | pending | path or URL |
 
-## Decision Log
+## Step 2: Scale
-(Updated as the workflow progresses)
-```
 
-Also save the plan with `memory_remember` (type: `fact`, key: `deepresearch.<slug>.plan`) so it survives context truncation.
+Use direct search for:
+- Single fact or narrow question, including "what is X" explainers
+- Work you can answer with 3-10 tool calls
 
-Present the plan to the user. If this is an unattended or one-shot run, continue automatically. If the user is actively interacting in the terminal, give them a brief chance to request plan changes before proceeding.
+For "what is X" explainer topics, you MUST NOT spawn researcher subagents unless the user explicitly asks for comprehensive coverage, current landscape, benchmarks, or production deployment.
+Do not inflate a simple explainer into a multi-agent survey.
 
-Do not stop after planning. If live search, subagents, web access, alphaXiv, or any other capability is unavailable, continue in degraded mode and write a durable blocked/partial report that records exactly which capabilities failed.
+Use subagents only when decomposition clearly helps:
+- Direct comparison of 2-3 items: 2 `researcher` subagents
+- Broad survey or multi-faceted topic: 3-4 `researcher` subagents
+- Complex multi-domain research: 4-6 `researcher` subagents
 
-## 2. Scale decision
+## Step 3: Gather Evidence
 
-| Query type | Execution |
+Avoid crash-prone PDF parsing in this workflow. Do not call `alpha_get_paper` and do not fetch `.pdf` URLs unless the user explicitly asks for PDF extraction. Prefer paper metadata, abstracts, HTML pages, official docs, and web snippets. If only a PDF exists, cite the PDF URL from search metadata and mark full-text PDF parsing as blocked instead of fetching it.
-|---|---|
-| Single fact or narrow question | Search directly yourself, no subagents, 3-10 tool calls |
-| Direct comparison (2-3 items) | 2 parallel `researcher` subagents |
-| Broad survey or multi-faceted topic | 3-4 parallel `researcher` subagents |
-| Complex multi-domain research | 4-6 parallel `researcher` subagents |
 
-Never spawn subagents for work you can do in 5 tool calls.
+If direct search was chosen:
+- Skip researcher spawning entirely.
+- Search and fetch sources yourself.
+- Use multiple search terms/angles before drafting. Minimum: 3 distinct queries for direct-mode research, covering definition/history, mechanism/formula, and current usage/comparison when relevant.
+- Record the exact search terms used in `<slug>-research-direct.md`.
+- Write notes to `<slug>-research-direct.md`.
+- Continue to synthesis.
 
-## 3. Spawn researchers
+If subagents were chosen:
+- Write a per-researcher brief first, such as `outputs/.plans/<slug>-T1.md`.
+- Keep `subagent` tool-call JSON small and valid.
+- Do not place multi-paragraph instructions inside the `subagent` JSON.
+- Use only supported `subagent` keys. Do not add extra keys such as `artifacts` unless the tool schema explicitly exposes them.
+- Always set `failFast: false`.
+- Do not name exact tool commands in subagent tasks unless those tool names are visible in the current tool set.
+- Prefer broad guidance such as "use paper search and web search"; if a PDF parser or paper fetch fails, the researcher must continue from metadata, abstracts, and web sources and mark PDF parsing as blocked.
 
-Launch parallel `researcher` subagents via `subagent`. Each gets a structured brief with:
+Example shape:
-- **Objective:** what to find
-- **Output format:** numbered sources, evidence table, inline source references
-- **Tool guidance:** which search tools to prioritize
-- **Task boundaries:** what NOT to cover (another researcher handles that)
-- **Task IDs:** the specific ledger rows they own and must report back on
 
-Assign each researcher a clearly disjoint dimension — different source types, geographic scopes, time periods, or technical angles. Never duplicate coverage.

-Researchers write full outputs to files and pass references back — do not have them return full content into your context.
+After evidence gathering, update the plan ledger and verification log. If research failed, record exactly what failed and proceed with a blocked or partial draft.
-Researchers must not silently merge or skip assigned tasks. If something is impossible or redundant, mark the ledger row `blocked` or `superseded` with a note.
 
-## 4. Evaluate and loop
+## Step 4: Draft
 
-After researchers return, read their output files and critically assess:
+Write the report yourself. Do not delegate synthesis.
-- Which plan questions remain unanswered?
-- Which answers rest on only one source?
-- Are there contradictions needing resolution?
-- Is any key angle missing entirely?
-- Did every assigned ledger task actually get completed, blocked, or explicitly superseded?
 
-If gaps are significant, spawn another targeted batch of researchers. No fixed cap on rounds — iterate until evidence is sufficient or sources are exhausted.
+Save to `outputs/.drafts/<slug>-draft.md`.
 
-Update the plan artifact (`outputs/.plans/<slug>.md`) task ledger, verification log, and decision log after each round.
+Include:
-When the work spans multiple rounds, also append a concise chronological entry to `CHANGELOG.md` covering what changed, what was verified, what remains blocked, and the next recommended step.
+- Executive summary
+- Findings organized by question/theme
+- Evidence-backed caveats and disagreements
+- Open questions
+- No invented sources, results, figures, benchmarks, images, charts, or tables
 
-Most topics need 1-2 rounds. Stop when additional rounds would not materially change conclusions.
+Before citation, sweep the draft:
+- Every critical claim, number, figure, table, or benchmark must map to a source URL, research note, raw artifact path, or command/script output.
+- Remove or downgrade unsupported claims.
+- Mark inferences as inferences.
 
-If no researcher files can be produced because tools, subagents, or network access failed, create `outputs/.drafts/<slug>-draft.md` yourself as a blocked report with:
+## Step 5: Cite
-- what was requested,
-- which capabilities failed,
-- what evidence was and was not gathered,
-- a proposed source-gathering plan,
-- no invented sources or results.
 
-## 5. Write the report
+If direct search/no researcher subagents was chosen:
+- Do citation yourself.
+- Verify reachable HTML/doc URLs with available fetch/search tools.
+- Copy or rewrite `outputs/.drafts/<slug>-draft.md` to `outputs/.drafts/<slug>-cited.md` with inline citations and a Sources section.
+- Do not spawn the `verifier` subagent for simple direct-search runs.
 
-Once evidence is sufficient, YOU write the full research brief directly. Do not delegate writing to another agent. Read the research files, synthesize the findings, and produce a complete document:
+If researcher subagents were used, run the `verifier` agent after the draft exists. This step is mandatory and must complete before any reviewer runs. Do not run the `verifier` and `reviewer` in the same parallel `subagent` call.
 
-```markdown
+Use this shape:
-# Title
 
-## Executive Summary
+```json
-2-3 paragraph overview of key findings.
+{
-
+  "agent": "verifier",
-## Section 1: ...
+  "task": "Add inline citations to outputs/.drafts/<slug>-draft.md using the research files as source material. Verify every URL. Write the complete cited brief to outputs/.drafts/<slug>-cited.md.",
-Detailed findings organized by theme or question.
+  "output": "outputs/.drafts/<slug>-cited.md"
-
+}
-## Section N: ...
-
-## Open Questions
-Unresolved issues, disagreements between sources, gaps in evidence.
 ```
 
-When the research includes quantitative data (benchmarks, performance comparisons, trends), generate charts using `pi-charts`. Use Mermaid diagrams for architectures and processes. Every visual must have a caption and reference the underlying data.
+After the verifier returns, verify on disk that `outputs/.drafts/<slug>-cited.md` exists. If the verifier wrote elsewhere, find the cited file and move or copy it to `outputs/.drafts/<slug>-cited.md`.
 
-Before finalizing the draft, do a claim sweep:
+## Step 6: Review
-- map each critical claim, number, and figure to its supporting source or artifact in the verification log
-- downgrade or remove anything that cannot be grounded
-- label inferences as inferences
-- if code or calculations were involved, record which checks were actually run and which remain unverified
 
-Save this draft to `outputs/.drafts/<slug>-draft.md`.
+If direct search/no researcher subagents was chosen:
+- Review the cited draft yourself.
+- Write `<slug>-verification.md` with FATAL / MAJOR / MINOR findings and the checks performed.
+- Fix FATAL issues before delivery.
+- Do not spawn the `reviewer` subagent for simple direct-search runs.
 
-## 6. Cite
+If researcher subagents were used, only after `outputs/.drafts/<slug>-cited.md` exists, run the `reviewer` agent against it.
 
-Spawn the `verifier` agent to post-process YOUR draft. The verifier agent adds inline citations, verifies every source URL, and produces the final output:
+Use this shape:
 
-```
+```json
-{ agent: "verifier", task: "Add inline citations to <slug>-draft.md using the research files as source material. Verify every URL.", output: "<slug>-brief.md" }
+{
+  "agent": "reviewer",
+  "task": "Verify outputs/.drafts/<slug>-cited.md. Flag unsupported claims, logical gaps, single-source critical claims, and overstated confidence. This is a verification pass, not a peer review.",
+  "output": "<slug>-verification.md"
+}
 ```
 
-The verifier agent does not rewrite the report — it only anchors claims to sources and builds the numbered Sources section.
+If the reviewer flags FATAL issues, fix them before delivery and run one more review pass. Note MAJOR issues in Open Questions. Accept MINOR issues.
 
-## 7. Verify
+When applying reviewer fixes, do not issue one giant `edit` tool call with many replacements. Use small localized edits only for 1-3 simple corrections. For section rewrites, table rewrites, or more than 3 substantive fixes, read the cited draft and write a corrected full file to `outputs/.drafts/<slug>-revised.md` instead.
 
-Spawn the `reviewer` agent against the cited draft. The reviewer checks for:
+The final candidate is `outputs/.drafts/<slug>-revised.md` if it exists; otherwise it is `outputs/.drafts/<slug>-cited.md`.
-- Unsupported claims that slipped past citation
-- Logical gaps or contradictions between sections
-- Single-source claims on critical findings
-- Overstated confidence relative to evidence quality
 
-```
+## Step 7: Deliver
-{ agent: "reviewer", task: "Verify <slug>-brief.md — flag any claims that lack sufficient source backing, identify logical gaps, and check that confidence levels match evidence strength. This is a verification pass, not a peer review.", output: "<slug>-verification.md" }
-```
 
-If the reviewer flags FATAL issues, fix them in the brief before delivering. MAJOR issues get noted in the Open Questions section. MINOR issues are accepted.
+Copy the final candidate to:
-After fixes, run at least one more review-style verification pass if any FATAL issues were found. Do not assume one fix solved everything.
+- `papers/<slug>.md` for paper-style drafts
+- `outputs/<slug>.md` for everything else
 
-## 8. Deliver
+Write provenance next to it as `<slug>.provenance.md`:
-
-Copy the final cited and verified output to the appropriate folder:
-- Paper-style drafts → `papers/`
-- Everything else → `outputs/`
-
-Save the final output as `<slug>.md` (in `outputs/` or `papers/` per the rule above).
-
-Write a provenance record alongside it as `<slug>.provenance.md`:

Briefly summarize the plan to the user and continue immediately. Do not ask for confirmation or wait for a proceed response unless the user explicitly requested plan review.
 - Start with a baseline sweep of the topic.
 - Use `schedule_prompt` to create the recurring or delayed follow-up instead of merely promising to check later.
 - Save exactly one baseline artifact to `outputs/<slug>-baseline.md`.
