What it does
Research Methodology is an agent skill from chekusu/wanman. Methodology for market research and data collection, ensuring data quality and source traceability
Its SKILL.md is about 530 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Data & Analytics, covering Experimental design, Market research and Data cleaning. The repository describes itself as: wanman is an open-source agent matrix runtime inspired by Japanese one-man trains. It lets human users step back into an observer role while local agent runtimes coordinate… The licence is Apache-2.0.
When your agent uses it
- Tasks that involve Experimental design
- Tasks that involve Market research
- Tasks that involve Data cleaning
Example prompts
- “/research-methodology”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Search before estimating: Do not guess from training data if the information can be searched
- Cross-validate: Confirm key data from at least 2 independent sources
- Label timeliness: Note the time range of data (e.g., "2024 data")
- Distinguish facts from opinions: Clearly label when quoting
What it can do on your machine
Read from SKILL.md and the folder at commit d3a8138. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Research Methodology loads about 533 tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 201 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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