Research Solutions

You are tasked with analyzing solution options for new features or changes by invoking parallel skills and synthesizing their findings into actionable recommendations optimized for design consumption.

Initial Setup:

When this command is invoked, respond with:

I'm ready to research solution options. Please provide:
- What feature/change you want to explore
- Any requirements or constraints you know about
- Reference to relevant ticket or research documents if available

I'll analyze the current codebase, generate solution options, and provide recommendations.

Then wait for the user's request.

Steps

Step 1: Read Mentioned Files

• If user mentions tickets, research docs, or other files, read them FULLY first
• IMPORTANT: Use Read tool WITHOUT limit/offset parameters
• CRITICAL: Read these files in main context before invoking skills
• Extract requirements, constraints, and goals
• Identify what problem we're solving

Step 2: Generate Candidates and Dimensions

Generate 2–4 named candidates from three sources, then merge into one shortlist:

• Ecosystem scan — spawn web-search-researcher for any topic where the candidate space includes external libraries, frameworks, or services. Prompt it to return 2–4 named options with one-line "what it is" + canonical doc link per option. Skip only when the topic is wholly internal (e.g., "how to organize this service layer") and the orchestrator's design-space enumeration plus the user shortlist already cover the space.
• Design-space enumeration — orchestrator names abstract shapes from first principles when applicable (pub/sub vs direct-call vs event-bus; sync vs async; manual mapping vs auto-mapper). One-line "what it is" per shape.
• User shortlist — if the user pre-named candidates in the entry prompt ("compare TanStack Query vs SWR"), include those verbatim.

Merge to 2–4 candidates total. Name each with a short noun phrase ("TanStack Query", "Direct event bus"). Deduplicate.

Default dimension list (presented at Step 3; developer may drop irrelevant ones):

• approach-shape (hybrid) — what category of solution the candidate is, what core moving parts it requires.
• precedent-fit (codebase-anchored) — does the existing code already use this pattern; how many call sites would adopt the new option.
• integration-risk (codebase-anchored) — which existing seams the candidate would touch; what breaks if it lands.
• migration-cost (external-anchored for libraries; codebase-anchored for in-house code) — work to introduce the candidate plus work to remove the incumbent if there is one.
• verification-cost (codebase-anchored) — test/CI surface needed to make the candidate safe to adopt.
• novelty (external-anchored) — how recently the candidate emerged, ecosystem momentum, deprecation risk.

Hold the candidate set and default dimension list in working state for the Step 3 checkpoint. Do not dispatch fit agents yet.

Step 3: Candidate Checkpoint

Present the candidate set and default dimensions to the developer before per-candidate fit dispatch.

1. Show candidates and dimensions:

   ## Candidates for: [Topic]
   
   1. [Candidate A] — [one-line what it is]
   2. [Candidate B] — [one-line what it is]
   ...
   
   Dimensions (default 6; drop any that don't apply):
   - approach-shape · precedent-fit · integration-risk
   - migration-cost · verification-cost · novelty
   

2. Confirm via the ask_user_question tool with the following question: "[N] candidates, [D] dimensions. Begin per-candidate fit dispatch?". Header: "Candidates". Options: "Proceed (Recommended)" (Begin per-candidate fit dispatch with all [N] candidates and all [D] dimensions); "Adjust candidates or dimensions" (Rename, add, or drop candidates; drop dimensions that don't apply); "Re-generate candidates" (Candidates look wrong — re-run Step 2 with adjusted scope).

3. Handle developer input:

   "Proceed": lock the candidate × dimension set; advance to Step 4.

   "Adjust candidates or dimensions": ask the follow-up free-text question with prefix ❓ Question: — "Which candidates and dimensions should be added, dropped, or renamed?" — apply edits to the working set, re-present, and confirm again with the same three-option ask_user_question.

   "Re-generate candidates": ask the follow-up free-text question with prefix ❓ Question: — "What should be different in candidate generation? (narrower/wider scope, different ecosystem, exclude approach X, …)" — return to Step 2 with the updated scope, then re-enter Step 3.

   Loop until "Proceed" is selected.

Step 4: Per-Candidate Fit Dispatch (parallel agents)

For each confirmed candidate, dispatch up to two agents in parallel — total ≤ 2 × N agents:

• One codebase-analyzer per candidate — when ≥1 kept dimension is codebase-anchored (precedent-fit, integration-risk, often migration-cost and verification-cost). The agent scores the candidate on every kept codebase-anchored dimension in a single pass, returning evidence per dimension with file:line references.
• One web-search-researcher per candidate — when ≥1 kept dimension is external-anchored (novelty, often migration-cost for libraries, approach-shape for ecosystem options). The agent scores the candidate on every kept external-anchored dimension in a single pass, returning evidence per dimension with doc/source links.

Skip either agent for a candidate when no dimension of that anchor-type was kept. Hybrid dimension approach-shape is scored by the orchestrator after both agents return, by combining their per-candidate findings.

Per-candidate prompt shape (use the same outer template, fill in candidate name and kept dimensions):

Candidate: [name] — [one-line what it is]
Topic: [topic from Step 1]

Score this single candidate on the following dimensions, each with concrete evidence ([file:line] for codebase, doc/source link for external). Report findings as one section per dimension.

Dimensions for this run:
- [dimension name] — [one-line of what to look for]
- ...

Do NOT compare against other candidates; another agent handles each one separately. Focus on depth of evidence for THIS candidate.

Wait for ALL agents to complete before proceeding.

Coverage check: every (candidate × kept-dimension) cell is filled — by an agent's evidence or by an explicit null ("does not apply to this candidate"). Cells silently dropped indicate a missing dispatch — re-run that candidate's agent.

Step 5: Synthesize and Recommend

• Cross-reference per-candidate findings — fill the candidate × dimension grid with evidence per cell.
• Apply the fit filter qualitatively per candidate: a candidate "clears" when no kept dimension surfaces a blocking concern (integration-risk that breaks load-bearing seams, migration-cost that exceeds the topic's scope, verification-cost with no path to coverage).
• If ≥1 candidate clears the fit filter: pick the strongest, document rationale with evidence, and explain why alternatives weren't chosen. Identify conditions that would change the recommendation.
• If every candidate fails the fit filter: produce a "no-fit" recommendation — list each candidate's blocking dimension with evidence, recommend re-scoping the question or expanding the candidate pool, and set Step 7 frontmatter confidence: low and status: blocked.

Step 6: Determine Metadata and Filename

• Filename format: thoughts/shared/solutions/YYYY-MM-DD_HH-MM-SS_[topic].md
  • YYYY-MM-DD_HH-MM-SS: Current date and time (e.g., 2025-10-11_14-30-22)
  • [topic]: Brief kebab-case description
• Repository name: from git root basename, or current directory basename if not a git repo
• Use the git branch and commit from the git context injected at the start of the session (or run git branch --show-current / git rev-parse --short HEAD directly)
• Researcher: use the User from the git context injected at the start of the session (fallback: "unknown")
• If metadata unavailable: use "unknown" for commit/branch

Step 7: Generate Solutions Document

• Use the metadata gathered in step 6

• Structure the document with YAML frontmatter followed by content:

  ---
  date: [Current date and time with timezone in ISO format]
  researcher: [Researcher name]
  git_commit: [Current commit hash]
  branch: [Current branch name]

  status: ready | awaiting_input | blocked
  tags: [solutions, component-names]

Step 8: Present Findings

• Present concise summary with clear recommendation
• Highlight key integration points
• Ask if they want to proceed to /skill:design with the chosen option or need clarification

Step 9: Handle Follow-up Questions

• If user has questions, append to same document
• Update frontmatter: last_updated and last_updated_by
• Add section: ## Follow-up Analysis [timestamp]
• Spawn additional agents as needed

Important Notes

• Always use parallel Agent tool calls to maximize efficiency and minimize context usage
• Always spawn fresh research to validate current state - never rely on old research docs as source of truth
• Old research documents can provide historical context but must be validated against current code
• Generate 2-4 named candidates in Step 2; confirm them with the developer at Step 3 before per-candidate fit dispatch
• Web-search-researcher is a first-class Step 2 agent for ecosystem candidate-source — skip only when the topic is wholly internal and design-space enumeration plus user shortlist cover the space
• Per-candidate fit dispatch caps at two agents per candidate (one codebase-analyzer, one web-search-researcher) — skip either when no dimension of its anchor-type was kept
• Solutions documents should be self-contained with all necessary context
• Each agent prompt should be specific and focused on a single candidate scored on the kept dimensions
• Quantify pattern precedent — count usage in codebase, don't just say "follows pattern"
• Ground complexity estimates in actual similar work from git history
• Think like a software architect — option-shopping output is 2–4 comparable candidates plus an honest fit verdict
• Keep the main agent focused on synthesis and comparison, not deep implementation details
• Encourage agents to find existing patterns and examples, not just describe possibilities
• Resolve technical unknowns during research — don't leave critical questions for design
• File reading: Always read mentioned files FULLY (no limit/offset) before invoking skills
• Critical ordering: Follow the numbered steps exactly
  • ALWAYS read mentioned files first before invoking skills (step 1)
  • ALWAYS generate candidates and run the Step 3 checkpoint before per-candidate dispatch (steps 2 → 3 → 4)
  • ALWAYS wait for all per-candidate agents to complete before synthesizing (step 4)
  • ALWAYS gather metadata before writing the document (step 6 before step 7)
  • NEVER write the solutions document with placeholder values
