task: compare three credible explanations
inspect:
- source authority
- publication date
- supporting evidence
verify: claims + citationsWhy general browsing falls short
Finding information is easy. Knowing what deserves trust takes a process.
A quick search can mix primary evidence, copied summaries, outdated pages, commercial claims, and opinion. The difficult part is deciding which sources answer the question and where the evidence disagrees.
These research skills guide Codex through query planning, source evaluation, fact checking, comparison, note organization, and synthesis. The result is easier to audit and less likely to hide weak evidence behind confident writing.
What the downloadable skills can do
What Codex Skills for Research can help Codex investigate
02
Evaluate source quality
Check authorship, publication context, date, evidence, incentives, and whether a source is primary, secondary, or repeating another claim.
03
Compare claims across sources
Create an evidence map that shows agreement, conflict, missing information, and which conclusions have the strongest support.
04
Write traceable research outputs
Produce briefs, comparison tables, timelines, annotated notes, or long-form synthesis with each important claim tied back to its source.
A research loop you can inspect
From a vague question to a defensible research brief
The workflow separates discovery from judgment. Codex gathers candidates first, evaluates them against the task, then writes only after the evidence has been organized.

Context → Plan → Work → Verify
01
Define the decision
Clarify what the reader needs to know, the time range, geography, source types, and the level of confidence required.
02
Search in deliberate passes
Use broad discovery, focused follow-up searches, primary-source checks, and citation trails instead of one oversized query.
03
Record evidence and uncertainty
Capture source details, useful passages, contradictions, limitations, and unanswered questions while the research is still fresh.
04
Synthesize without flattening disagreement
Separate established facts from interpretation and label uncertain or conflicting findings instead of forcing one neat conclusion.
Useful across research contexts
Build the workflow around the kind of evidence you need
The core research process stays stable, while the preferred sources and output format change with the assignment.
Web research
Investigate current topics using authoritative pages, official records, reputable reporting, and direct source verification.
Market research
Compare competitors, positioning, customer language, product claims, and category patterns without treating marketing copy as proof.
Policy research
Trace laws, regulations, public guidance, consultations, and implementation details back to official sources.
Technical research
Use official documentation, standards, release notes, specifications, and primary engineering sources for technical claims.
Common research assignments
Use the skills whenever the answer needs evidence, not guesswork
Each task can be adjusted for depth, source rules, freshness, and the final format.
01Create a sourced background brief
02Compare competing products or approaches
03Verify claims in an article or draft
04Build a timeline from primary records
05Summarize a complex topic for a new reader
06Map areas of agreement and disagreement
07Turn research notes into a structured report
08Identify evidence gaps before a decision
A practical fit
Who Is This For?
These skills suit people who need research that can be checked, reused, and handed to someone else without losing the source trail.
Writers and editors
Research unfamiliar subjects, verify factual statements, and build source notes before drafting or publishing.
Analysts and strategists
Compare markets, organizations, policies, or technologies with a consistent evidence framework.
Founders and product teams
Investigate customer problems, alternatives, competitors, and technical choices before committing resources.
Independent researchers
Create a repeatable system for web research, note organization, source comparison, and clear reporting.
Good to know:
The skills improve research discipline, but they cannot make a weak source reliable. Important decisions still require human review, domain expertise, and access to the right evidence.
Set up your research workflow
Installation Guide
Install the skills for one research repository or make them available across every project where you use Codex.
Download and extract the research skills
Keep each SKILL.md file together with its references, scripts, query guides, and output instructions.
Choose the right scope
Use the repository location for research rules tied to one project, or the user location for a general research workflow.
Add your source rules
Record preferred domains, freshness requirements, citation style, excluded source types, and the evidence threshold for the project.
Open Codex in the working folder
Codex detects installed skills automatically. Restart Codex if a newly added skill does not appear.
Start with a real research question
Invoke the skill directly or describe the assignment, audience, deadline, and source requirements in the prompt.

Frequently Asked Questions
Answers about source quality, citations, current information, and using research skills responsibly.
Can these skills browse the web for current information?+
They can guide Codex through web research when web access is available. The workflow prioritizes relevant, authoritative, and recent sources based on the assignment.
Will every claim include a citation?+
The skills can require citations for factual claims and keep a source trail. You can tighten the rules for high-stakes research or use lighter sourcing for exploratory work.
Can I define sources Codex must use or avoid?+
Yes. Add preferred databases, official domains, source types, date limits, and exclusions to the project instructions or the skill configuration.
Do the skills prevent hallucinations?+
No workflow removes all risk. They reduce it by requiring source checks, explicit uncertainty, and traceable evidence, but important findings still need review.
How is this different from a single research prompt?+
A prompt describes one task. A skill preserves a reusable process for planning searches, evaluating sources, recording evidence, and producing consistent outputs.
Research with a visible source trail
Give Codex a method for finding evidence, testing it, and explaining what it supports.
Focused searches. Better source judgment. Clearer notes. Conclusions that are easier to verify.
