This document is the canonical workflow description for the trekresearch pipeline as of v2.4.0. The /trekresearch command reads it as reference and executes the phases below inline in the main command context. It is no longer spawned as a background sub-agent — that mode silently lost the Agent tool and degraded the swarm to single-context reasoning.

The role of the "orchestrator" now belongs to the command markdown itself: the main Opus session launches local + external agents via the Agent tool, collects their results, triangulates, and writes the research brief.

Design principle: Context Engineering

Your job is to build the RIGHT context — not all context. Each agent gets a focused prompt relevant to the research question. The value is in triangulation (cross-checking local vs. external findings) and synthesis (insights that only emerge from combining both perspectives).

Input

You will receive a prompt containing:

• Research question — what the user wants to understand
• Dimensions (optional) — specific facets to investigate
• Mode — default, local, external, or quick
• Brief destination — where to write the research brief
• Plugin root — for template access

Your workflow

Execute these phases in order. Do not skip phases.

Phase 1 — Agent group selection

Based on the mode, determine which agent groups to launch:

Mode	Local agents	External agents
default	Yes	Yes
local	Yes	No
external	No	Yes
quick	N/A — handled inline by the command, not the orchestrator

No bridge agent (v5.10.1). The third-party second-opinion bridge was dropped by operator directive; there is no bridge column to select.

Local agents (reuse existing plugin agents with research-focused prompts):

Agent	Purpose in research context
architecture-mapper	How the codebase's architecture relates to the research question
dependency-tracer	Which modules and dependencies are relevant to the research topic
task-finder	Existing code that relates to the research question (reuse candidates, patterns)
git-historian	Recent changes and ownership patterns relevant to the topic
convention-scanner	Coding patterns relevant to evaluating fit of researched options

External agents (new research-specialized agents):

Agent	Purpose
docs-researcher	Official documentation, RFCs, vendor docs
community-researcher	Real-world experience, issues, blog posts, discussions
security-researcher	CVEs, audit history, supply chain risks
contrarian-researcher	Counter-evidence, overlooked alternatives, reasons to reconsider

Phase 2 — Parallel research

Launch ALL selected agents in parallel using the Agent tool — one message, multiple tool calls. This maximizes concurrency.

Prompting local agents for research (not planning):

Local agents are designed for planning context, but they work equally well for research when prompted correctly. The key: frame the prompt around the research question, not a task to implement.

Examples:

• architecture-mapper: "Analyze the codebase architecture relevant to this question: {research question}. Focus on patterns, tech stack choices, and structural decisions that relate to {topic}. Report how the current architecture would support or conflict with {options being researched}."
• dependency-tracer: "Trace dependencies and data flow relevant to {research question}. Identify which modules would be affected by {topic}. Map external integrations that relate to {options being researched}."
• task-finder: "Find existing code relevant to {research question}. Look for prior implementations, patterns, utilities, or abstractions that relate to {topic}. Classify as: directly relevant, partially relevant, reference only."
• git-historian: "Analyze git history relevant to {research question}. Look for recent changes to {relevant areas}, who owns that code, and whether there are active branches touching related files."
• convention-scanner: "Discover coding conventions relevant to evaluating {research question}. Which patterns would a solution need to follow? What constraints do existing conventions impose on {options being researched}?"

Prompting external agents:

Pass the research question, specific dimensions to investigate, and any context from the interview about what the user already knows or cares about.

Phase 3 — Targeted follow-ups

Review all agent results. Identify knowledge gaps — areas where findings are thin, contradictory, or missing entirely. Launch up to 2 targeted follow-up agents (Sonnet, Explore or web search) with narrow briefs.

If no gaps exist, skip: "Initial research sufficient — no follow-ups needed."

Phase 4 — Triangulation

This is the KEY phase that makes trekresearch more than aggregation.

For each dimension of the research question:

1. Collect — gather relevant findings from local AND external agents
2. Compare — do local findings agree with external findings?
3. Flag contradictions — where they disagree, present both sides with evidence
4. Cross-validate — use codebase facts to validate external claims, and vice versa
5. Rate confidence — based on source quality, agreement level, and evidence strength

Confidence ratings:

• high — multiple authoritative sources agree, local evidence confirms
• medium — good sources but limited cross-validation, or partial local confirmation
• low — single source, conflicting information, or no local validation
• contradictory — credible sources actively disagree, requires human judgment

Example of triangulation producing NEW insight:

• Local: "The codebase uses Express middleware pattern extensively"
• External: "Fastify is 3x faster than Express"
• Triangulation insight: "Migration to Fastify would require rewriting 14 middleware files (local count). The performance gain is real (external) but the migration cost is high. Express 5 offers a 40% improvement as a drop-in upgrade (external) — this may be the pragmatic path given the existing middleware investment (synthesis)."

Phase 5 — Synthesis and brief writing

Read the research brief template from the plugin templates directory: {plugin root}/templates/research-brief-template.md

Write the research brief following the template structure. Key rules:

1. Executive Summary — 3 sentences max. Answer, confidence, key caveat.
2. Dimensions — each with local findings, external findings, contradictions.
3. Synthesis section — this is NOT a summary. It is NEW insight from triangulation. Things that only become visible when local context meets external knowledge.
4. Open Questions — things that remain unresolved. Each is a candidate for follow-up.
5. Recommendation — only if the research was decision-relevant. Omit for exploratory.
6. Sources — every finding traced to a URL or codebase path with quality rating.

Write the brief to the destination path provided in your input. Create the .claude/research/ directory if needed.

Phase 6 — Completion

When done, your output message should contain:

## Ultraresearch Complete (Background)

**Question:** {research question}
**Brief:** {brief path}
**Confidence:** {overall confidence 0.0-1.0}
**Dimensions:** {N} researched
**Agents:** {N} local + {N} external

### Key Findings
- {Finding 1}
- {Finding 2}
- {Finding 3}

### Contradictions Found
- {Contradiction 1, or "None — findings are consistent"}

### Open Questions
- {Question 1, or "None"}

You can:
- Read the full brief at {brief path}
- Feed into planning: /trekplan --research {brief path} <task>
- Ask follow-up questions

Rules

• Scope: Codebase analysis is limited to the current working directory. External research has no such limit.
• Cost: Sub-agents use their pinned model: frontmatter (currently opus for all). A phase_signals[<phase>].model brief signal or the active --profile (e.g. economy) overrides the model per-phase. You (the orchestrator) run on Opus.
• Privacy: Never log secrets, tokens, or credentials in the brief.
• Sources: Every claim in the brief must cite a source (URL or file path). Never invent findings.
• Honesty: If a question is trivially answerable, say so. Don't inflate research.
• Graceful degradation: If MCP tools are unavailable (Tavily, MS Learn), proceed with available tools and note the limitation in the brief metadata.
• Independence: Do not pre-bias external agents with local findings or vice versa. The value is in independent perspectives that are THEN triangulated.
• No placeholders: Never write "TBD", "further research needed", or similar without specifying what exactly is missing and why it could not be determined.
