sequential_search
Read-only
Record research steps, track unanswered questions, and explore alternative angles by branching from any step during web research projects.
Instructions
Keep track of a multi-step research project. Use this alongside web_search or search_and_scrape to record what you've found at each step, note unanswered questions, and explore alternative angles (branching). Start a new session with stepNumber=1, then pass the returned sessionId for each follow-up step. Mark the session complete by setting nextStepNeeded=false. Sessions stay active for 4 hours between steps and persist across restarts. Use get_research_session to recover a session after context loss.
Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| searchStep | Yes | Summary of what was researched or discovered in this step. Be descriptive to build a useful research trail.,required | |
| stepNumber | Yes | Current step number (start at 1 for a new session). Must increment sequentially.,required | |
| nextStepNeeded | Yes | Set true if more research steps will follow; false to mark the session complete.,required | |
| totalStepsEstimate | No | Your estimate of total steps needed. Update as scope becomes clearer. | |
| sessionId | No | Session ID returned from the first call. Required for steps 2+. Omit to start a new session. | |
| isRevision | No | Set true if this step revises a previous step's findings. | |
| revisesStep | No | The step number being revised (required if isRevision is true). | |
| branchFromStep | No | Step number to branch from, for exploring alternative research directions. | |
| branchId | No | Identifier for this research branch (e.g. 'technical-approach' vs 'business-angle'). | |
| knowledgeGap | No | A specific gap or unanswered question identified during this step that needs further investigation. | |
| researchGoal | No | The question or goal driving this research. Set on step 1; ignored on later steps. | |
| reasoning | No | Why you chose this search direction over alternatives. | |
| confidence | No | Confidence in this step's findings: high, medium, or low. | |
| rejectedApproaches | No | Approaches considered but rejected, with brief reasons. | |
| sessionSummary | No | Running summary of research so far. Update periodically for better session recovery. | |
| responseMode | No | Force response format: full or summary. Default: auto (full for 8 or fewer steps, summary for more). |
