research-methodology

research-methodology is a skill for Claude Code, Codex from chekusu/wanman. It costs 20 tokens per session (519 once invoked), scanned A, original, Apache-2.0.

A method for collecting market research data with source records, confidence scores, time labels, and a distinction between facts and estimates.

In plain words
What is it for?
It helps choose sources, search before estimating, confirm important data independently, and record findings with their source and confidence.
Why use it?
It reduces unsupported claims and makes it easier to check where each research finding came from.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

research-methodology scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Research Methodology

Core Principles

Every data point must have a source and confidence score. Estimates are not facts — label them as estimates.

Data Source Hierarchy

Tier Source Type Confidence Range Examples
1 Official public data 0.85-0.95 Government statistics, public company filings, industry association reports
2 Authoritative media 0.70-0.85 Major financial media, industry analysis reports
3 Web search results 0.50-0.70 Blogs, forums, review sites
4 Model inference/estimates 0.20-0.50 Extrapolations from known data, analogical estimates
5 Training data memory 0.10-0.30 Data from model memory (may be outdated)

Search Strategy

  1. Search before estimating: Do not guess from training data if the information can be searched
  2. Cross-validate: Confirm key data from at least 2 independent sources
  3. Label timeliness: Note the time range of data (e.g., "2024 data")
  4. Distinguish facts from opinions: Clearly label when quoting

Data Recording Format

Use wanman artifact put to record each research data point:

# Good recording practice
wanman artifact put --kind market_data --path "competitors/cafe_a/pricing" \
  --meta '{"source":"web_search:dianping.com","confidence":0.65,"data_date":"2024-12","avg_price":35,"currency":"CNY","category":"specialty_coffee"}'

# Bad practice (missing source and confidence)
wanman artifact put --kind market_data --path "competitors/pricing" \
  --meta '{"avg_price":35}'

Common Pitfalls

  • Survivorship bias: Successful cases found via search do not represent the full industry picture
  • Outdated data: Rent and foot traffic data from 2 years ago may have changed significantly
  • Regional differences: Tier-1 city data cannot be directly applied to tier-2 or tier-3 cities
  • Currency/unit confusion: Always label currency and measurement units
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
