What it does
Investigative Research is an agent skill from revfactory/harness-100. A specialized skill for the researcher and fact-checker agents covering investigative research. Provides primary/secondary source collection, source reliability assessment, data triangulation, and bias analysis methodologies. Use for 'research,' 'fact-checking,' 'source verification,' 'investigative techniques,' and similar topics.
Its SKILL.md is about 1.3k 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 Research & Science, covering Fact-checking and source verification. The licence is Apache-2.0.
When your agent uses it
- Source verification
- Investigative techniques
Example prompts
- “research,”
- “fact-checking,”
- “source verification,”
- “/investigative-research”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Minimum 3 independent sources: Cross-confirm key facts from 3 different sources
- Primary sources first: Whenever possible, verify original data or reports directly
- Recency: Statistics within the last 3 years; for fast-changing fields, within 1 year
- Collect opposing views: Intentionally collect materials from opposing positions
What it can do on your machine
Read from SKILL.md and the folder at commit 8e8d35c. 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.
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
Investigative Research loads about 1.3k tokens when it runs. Until then it costs about 89 tokens; SKILL.md has 469 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.

Investigative Research — Investigative Research Methodology
Specialized knowledge used by the researcher and fact-checker agents when investigating and verifying materials for documentaries.
Why Systematic Research Is Needed
A documentary's credibility depends on the depth and accuracy of its research. A single incorrect statistic can undermine the entire program's trust. There is a fundamental difference between "casually searching and using" versus "verifying at investigative journalism standards."
Source Collection Hierarchy: PRIMA Framework
| Tier | Description | Reliability | Example |
|---|---|---|---|
| Primary | Primary sources — original data, direct interviews | Highest | Census raw data, firsthand testimony |
| Refereed | Peer-reviewed academic sources | High | Academic papers, meta-analyses |
| Institutional | Reports published by institutions | Medium-High | WHO reports, central bank statistics |
| Media | Verified news coverage | Medium | Major news outlet articles, reportage |
| Anecdotal | Anecdotes, personal experiences | Low | Social media, blogs, community posts |
Source Collection Rules
- Minimum 3 independent sources: Cross-confirm key facts from 3 different sources
- Primary sources first: Whenever possible, verify original data or reports directly
- Recency: Statistics within the last 3 years; for fast-changing fields, within 1 year
- Collect opposing views: Intentionally collect materials from opposing positions
Source Reliability Assessment: CRAAP Test
| Criterion | Question | Weight |
|---|---|---|
| Currency | When was it published? Updated? | 20% |
| Relevance | Is it directly related to the topic? | 15% |
| Authority | What are the author/institution's expertise and credentials? | 25% |
| Accuracy | Does it match other sources? Is there evidence? | 25% |
| Purpose | Information? Persuasion? Advertising? Political purpose? | 15% |
Reliability Grades
| Score | Grade | Usability |
|---|---|---|
| 80-100 | A (Highly Reliable) | Can be used as core fact |
| 60-79 | B (Reliable) | Use as supporting material, cross-check recommended |
| 40-59 | C (Caution) | Reference only, cross-check required |
| 20-39 | D (Suspect) | Do not use directly, cite only as a perspective |
| 0-19 | F (Disqualified) | Do not use |
Data Triangulation

Method Triangulation
(Different research methods)

Data Triangulation --- Investigator Triangulation
(Different data sources) (Different analysts)| Type | Method | Example |
|---|---|---|
| Data Triangulation | Confirm the same fact from different sources | Government statistics + academic paper + field observation |
| Method Triangulation | Verify the same phenomenon with different methods | Interview + statistical analysis + literature review |
| Perspective Triangulation | Confirm from different stakeholders' viewpoints | Government + NGO + affected parties |
Bias Analysis Checklist
| Bias Type | Detection Question | Countermeasure |
|---|---|---|
| Confirmation Bias | Are we only collecting data that supports our desired conclusion? | Intentionally search for counter-evidence |
| Survivorship Bias | Are we only looking at success stories? What about failures? | Investigate failure cases with equal weight |
| Selection Bias | Are we only representing a specific group? | Include materials from diverse demographic groups |
| Recency Bias | Are we overvaluing recent events? | Include historical context |
| Framing Bias | Are we defining the problem in only one way? | Try redefining with a different frame |
