Quick Summary
Goal: Run broad web research, classify and deduplicate candidate sources, and produce a tiered source map + gap list for source-deep-dive, never a final report.
Summary:
- Purpose: Breadth-first discovery + triage for
source-deep-dive; produce a tiered, deduplicated source map, never synthesis. - Main steps (all 5, in order): (1) Define scope — parse topic; generate 5-10 angle-varied queries (overview, current-state, comparison, data, expert, criticism); (2) Execute searches — run
WebSearchper query (≤10 calls); record title/URL/snippet/source type; (3) Triage — classify each result Tier 1-4; dedupe; (4) Build map — writetmp/research/_sources-{slug}.md(Sources + Gaps Identified); (5) Identify gaps — note underexplored angles forsource-deep-dive. - Hard-cap fan-out at 10
WebSearchcalls/invocation; generate 5-10 varied queries, then stop; breadth then triage, not deep-dive. - Tier every result (.gov/.edu/official > industry reports > established blogs/Wikipedia > forums/social); dedupe URL/syndicated content before counting.
- Deliverable: intermediate source map at
tmp/research/_sources-{slug}.md(Sources + Gaps Identified), not synthesis; hand off tosource-deep-dive. - Mine gaps: missing perspectives, quantitative data, stale recency; guide the next deep dive.
- Chain mode (caller-passed
--chain=deep-dive): after Step 5, readreferences/research-chain.mdand runsource-deep-diveSteps 1-5 inline, leavingtmp/research/_evidence-{slug}.md; without the flag stop at Step 5 exactly as above.
Workflow:
- Define scope — Parse topic; generate 5-10 varied queries
- Execute searches — Run
WebSearch; collect results - Source triage — Classify each source Tier 1-4; dedupe
- Build source map — Write structured source list to working file
- Identify gaps — Note underexplored angles for
source-deep-dive
Key Rules:
- Maximum 10 WebSearch calls per invocation
- Follow source hierarchy: Official docs (Tier 1) > Peer-reviewed (Tier 2) > Industry blogs (Tier 3) > Forums (Tier 4)
- Output intermediate source map, not final report
MUST ATTENTION Apply skeptical, sequential thinking; trace every claim and state confidence (>80% to act).

Web Research
Knowledge Work Rules (canonical for the research chain)
Web Research Protocol — Factual claims require 2+ independent sources. Rank sources Tier 1 (.gov/.edu/official) > Tier 2 (industry reports) > Tier 3 (credible blogs; cross-validate) > Tier 4 (unverified; NEVER cite as fact). Declare confidence (95/80/60/<60%) for every finding.
- Follow source hierarchy (official docs > peer-reviewed > industry blogs > forums) for factual claims
- Cite sources with Tier classification (inline
[N]) - Cross-validate claims with 2+ independent sources
- Declare confidence: 95/80/60/<60%
- Use enforced template; include all sections
- Working files →
tmp/research/(project-root, disposable); final output →docs/knowledge/ - Query budget — one rule for the chain: 5-10 angle-varied
WebSearchqueries, at most 10 calls here;source-deep-divethen fetches at most 8 sources.workflow-researchmay lower the depth for a Narrow question (3-5 queries) but never raises a cap. The genericweb-researchprotocol guide below (3-5 queries) is the floor for ad-hoc lookups in other skills and never overrides these caps.
These rules are canonical for the research chain; source-deep-dive and knowledge-synthesis read them from this file.
Step 1: Define Search Scope
Parse topic; generate 5-10 queries:
- Definition/overview — "what is {topic}"
- Current state — "{topic} 2026" or "{topic} latest"
- Comparison — "{topic} vs alternatives"
- Data/statistics — "{topic} market size" or "{topic} statistics"
- Expert opinion — "{topic} expert analysis" or "{topic} review"
- Criticism/risks — "{topic} challenges" or "{topic} risks"
Step 2: Execute Searches
For each query:
- Run
WebSearch. - Record title, URL, snippet, apparent source type.
- Stop after 10 calls.
Step 3: Source Triage
For each result, classify Tier:
- Tier 1: .gov, .edu, official docs, peer-reviewed
- Tier 2: Industry reports, major publications
- Tier 3: Established blogs, verified experts, Wikipedia
- Tier 4: Forums, personal blogs, social media
Filter duplicate URLs and syndicated content.
Step 4: Build Source Map
Write to tmp/research/_sources-{slug}.md:
# Source Map: {Topic}
**Date:** {date}
**Queries executed:** {count}
**Sources found:** {count} (Tier 1: N, Tier 2: N, Tier 3: N, Tier 4: N)
## Sources
| # | Title | URL | Tier | Relevance | Notes |
| --- | ----- | --- | ---- | --------- | ------------- |
| 1 | ... | ... | 1 | High | Official docs |
## Gaps Identified
- {angle not covered}
- {topic needing deeper research}
Step 5: Identify Gaps
Review source map for:
- Missing perspectives (only positive sources? need criticism)
- Missing data types (no quantitative data? need statistics)
- Recency issues (all sources old? need current data)
Note gaps for source-deep-dive.
Chain Mode (--chain=deep-dive)
[BLOCKING] MUST ATTENTION when the caller passed --chain=deep-dive, read references/research-chain.md now and follow it: it runs source-deep-dive Steps 1-5 from that skill's own file and writes the evidence base, then returns. Without the flag, skip this section and the run ends at the source map.
Next Steps
Inside a workflow: when this skill runs as a step of an active workflow, skip the prompts in this section and return the result — the workflow's next step decides what runs (
/start-workflow→ Step Execution Protocol, Workflow-step mode).
Without --chain=deep-dive only (chain mode follows references/research-chain.md). MANDATORY IMPORTANT MUST ATTENTION — NO EXCEPTIONS: After completion, use ask user question tool; user chooses:
- "/source-deep-dive (Recommended)" — Deep-dive into top sources
- "/market-analysis" — If sizing the market (TAM/SAM/SOM), competitors, trends — required before
/business-evaluation - "/business-evaluation" — If evaluating business viability. Run
/market-analysisfirst — this skill consumes its sized-market output as evidence and MUST NOT re-derive market sizing. - "Skip, continue manually" — user decides
[IMPORTANT MUST ATTENTION] Use
TaskCreateto break work into small tasks BEFORE starting.
External Memory: For complex/lengthy research, analysis, scans, or reviews, write intermediate + final results to
tmp/reports/; prevents context loss and provides deliverable.
<!-- PROTOCOL-GUIDES:START -->Evidence Gate: MANDATORY IMPORTANT MUST ATTENTION Every claim, finding, recommendation needs
file:lineproof or traced evidence + confidence (>80% act; <80% verify first).
Protocol guides — Apply each protocol only when its read-when condition holds. If a protocol's text is not in your context, read its file below before you act on it.

Prompt-Enhance Closing Anchors
IMPORTANT MUST ATTENTION follow declared step order for this skill; NEVER skip, reorder, or merge steps without explicit user approval; inside a workflow run, /start-workflow → Workflow-step mode bounds this
IMPORTANT MUST ATTENTION for every step/sub-skill call: set in_progress before execution, set completed after execution
IMPORTANT MUST ATTENTION every skipped step MUST include explicit reason; every completed step MUST include concise evidence
IMPORTANT MUST ATTENTION if Task tools unavailable, maintain an equivalent step-by-step plan tracker with synchronized statuses
Closing Reminders
IMPORTANT MUST ATTENTION Goal: Run broad web research, classify and deduplicate candidate sources, and produce a tiered source map + gap list for source-deep-dive, never a final report.
IMPORTANT MUST ATTENTION — Protocols in force (concise digest of the SYNC/shared blocks this skill carries):
- Web Research: Cross-validate every claim across 2+ credible sources; NEVER cite one source as authoritative.
IMPORTANT MUST ATTENTION run ALL 5 main steps in order — (1) define scope + generate 5-10 angle-varied queries → (2) execute WebSearch (≤10 calls), record title/URL/snippet/type → (3) triage each result Tier 1-4 + dedupe → (4) build source map at tmp/research/_sources-{slug}.md → (5) identify gaps for source-deep-dive — why: skipping a step (esp. triage or gaps) yields untiered, gap-blind feedstock that breaks the next stage.
IMPORTANT MUST ATTENTION cap WebSearch at 10 calls per invocation; generate 5-10 angle-varied queries (overview, current-state, comparison, data, expert, criticism) then stop at the cap — why: bounded fan-out keeps this breadth-then-triage, not a deep-dive into one angle.
IMPORTANT MUST ATTENTION rank every source by tier (Tier 1 .gov/.edu/official > Tier 2 industry reports > Tier 3 established blogs/Wikipedia > Tier 4 forums/social) and dedupe by URL/syndicated content before it counts — why: tier ranking + dedupe keep the feedstock high-signal for source-deep-dive.
MANDATORY IMPORTANT MUST ATTENTION NEVER cite a Tier 4 / single source as authoritative — cross-validate every factual claim against 2+ independent sources and declare confidence (95/80/60/<60%) — why: one unverified source = a hallucination-amplifier downstream.
**MANDATORY IMPORTANT MUST ATTENTION** the deliverable is the intermediate source map at tmp/research/_sources-{slug}.md (sources table + Gaps Identified), NOT a synthesized report — hand it off to source-deep-dive; mine the set for gaps (missing perspectives, missing quantitative data, stale recency) so the next step knows where to dig.
**IMPORTANT MUST ATTENTION** with --chain=deep-dive, after Step 5 read references/research-chain.md and run source-deep-dive Steps 1-5 from its own SKILL.md (never from memory); without the flag stop at the source map — why: the flag is the only contract that lets one step own both halves while each skill still works alone.
**MANDATORY IMPORTANT MUST ATTENTION** break work into small todo tasks using TaskCreate BEFORE starting; add a final review todo task to verify work quality; transition one task at a time.
**IMPORTANT MUST ATTENTION** persist intermediate findings/results to a report file in tmp/reports/ for complex or lengthy work — why: external memory prevents context loss and is itself the deliverable.
**IMPORTANT MUST ATTENTION** a direct /web-research call is an explicit skill request: run it with no routing question and NEVER start a workflow from inside this skill; only the post-completion Next Steps question uses ask user question tool.
**IMPORTANT MUST ATTENTION** every claim, finding, and recommendation requires file:line proof or traced evidence with confidence percentage (>80% to act, <80% verify first) — NEVER speculate without proof.
Anti-Rationalization:
| Evasion | Rebuttal |
|---|---|
| "One strong source is enough" | NEVER — cross-validate against 2+ independent sources; Tier 4 is never authoritative |
| "I'll just write the report now" | Out of scope — output the source map + gaps; source-deep-dive synthesizes, not this |
| "Keep searching, more results help" | Hard-cap is 10 WebSearch calls — breadth then triage, never an unbounded crawl |
| "Topic is simple, skip tiering/dedupe" | Tier + dedupe every source — untiered feedstock degrades every downstream step |
| "Just do it, skip task tracking" | Skip depth, never skip tracking — TaskCreate first, one task in progress |
[TASK-PLANNING] Before acting, analyze task scope and systematically break it into small todo tasks and sub-tasks using TaskCreate.
IMPORTANT MUST ATTENTION Goal: triaged, tiered, deduplicated source map + gap list as feedstock for source-deep-dive — NOT a final report.
IMPORTANT MUST ATTENTION cap WebSearch at 10; cross-validate every claim with 2+ sources; NEVER cite Tier 4 as fact.
IMPORTANT MUST ATTENTION TaskCreate to break ALL work into small tasks BEFORE starting — this is very important.
