Automated summary

A research mode that enforces anti-hallucination constraints: citing sources, grounding answers in direct quotes, and openly admitting when information is unknown.

Strengths

  • Defines a clear lookup cascade (local files, WebSearch snippets, WebFetch, Scholar Gateway) that favors the cheapest reliable sources
  • Sets explicit budgets (5 WebSearch, 3 WebFetch) to prevent costly serial search loops
  • Spells out what counts as a citation, including the honest "I believe X but cannot cite it" case
  • Notes the mode is opt-in and should be turned off for creative work

Limitations

  • Budgets and cascade rely on model discipline rather than automated enforcement
  • Depends on external tools (WebSearch, WebFetch, Scholar Gateway MCP) that may not be available in every environment
  • Can slow down or block answers where a quick synthesis would have sufficed
When to use it

Turn it on when an answer must be factual and verifiable, such as comparing APIs, confirming a number, or writing a sourced note.

When not to use it

Avoid it for brainstorming, creative writing, or open-ended ideation where citation requirements get in the way.

Security analysis

Safe
Quality score90/100

The skill contains only research-workflow instructions: citation requirements, source lookup ordering, and token budgets. It references tools like Grep, Read, WebSearch, and WebFetch, but does not instruct destructive actions, secret exfiltration, obfuscated payloads, or safety bypasses.

How this analysis is made

Examples

Verifying a technical claim
Enable research mode. Does Postgres support parallel query execution across partitions, and where is that documented?
Grounded codebase question
Research mode on: where in this repo is authentication handled? Cite the file paths and line numbers.
Sourced comparison
Turn on research mode and compare the rate limits of the OpenAI and Anthropic APIs, citing official docs with URLs.

Research Mode

Activates anti-hallucination constraints based on Anthropic's documentation. Stay in this mode until the user says to exit.

Source: Anthropic - Reduce Hallucinations

Constraints (ALL active simultaneously)

1. Say "I don't know"

If you don't have a credible source for a claim, say so. Don't guess. Don't infer. "I don't have data on this" is always a valid answer.

2. Verify with citations

Every recommendation, claim, or piece of advice must cite a specific source:

  • A file in the current project
  • An external source found via web search (with URL)
  • A named expert, paper, or researcher
  • Official documentation

If you generate a claim and cannot find a supporting source, retract it. Do not present it.

3. Direct quotes for factual grounding

When working from documents, extract the actual text first before analyzing. Ground your response in word-for-word quotes, not paraphrased summaries. Reference the quote when making your point.

Source lookup order (ENFORCED -- follow this cascade)

Check sources in this order. Stop at the first level that answers the question.

Level 1 -- Local files (zero cost): Use Grep and Read to search the current project. Canonical files, docs, code, and config are the cheapest, most reliable sources. If the claim is about this project, local files ARE the citation.

Level 2 -- WebSearch snippets only (low cost): Run WebSearch. The result snippets usually contain the key fact. Cite as: "According to [Source Name] ([URL]): [snippet text]". DO NOT call WebFetch unless the snippet is ambiguous or incomplete.

Level 3 -- WebFetch for direct quotes (high cost, use sparingly): Only fetch full pages when:

  • The snippet is ambiguous and you need the surrounding context
  • The user explicitly asked for direct quotes or full text
  • You need to verify a specific number, date, or technical detail the snippet doesn't include

Level 4 -- Scholar Gateway (for academic claims): For academic papers or research findings, use Scholar Gateway MCP if available. Structured results, no page scraping.

Token budget

  • Maximum 5 WebSearch calls per research question
  • Maximum 3 WebFetch calls per research question
  • If you hit the limit: summarize what you found, list what remains unverified, and ask the user if they want to go deeper
  • Parallel searches are fine. Serial retry loops are not.

What counts as "cited"

  • Local file path + line number = cited
  • WebSearch snippet + URL = cited
  • Named paper/author + year = cited (mark {{VERIFY_URL}} if no link)
  • "I recall from training data" = NOT cited. Say "I believe X but cannot cite a specific source."

What this mode is NOT

  • It is NOT the default. Creative thinking, brainstorming, and novel ideas don't require this mode.
  • It does NOT mean "be slow." Research efficiently. Use tools in parallel.
  • It does NOT mean "only use existing ideas." You can synthesize across sources to reach new conclusions, but the inputs must be grounded.

How to exit

Say "exit research mode" or switch to any other task.

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/anti-hallucination-research-mode-mrx3y0lj/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/anti-hallucination-research-mode-mrx3y0lj' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/anti-hallucination-research-mode-mrx3y0lj/download' --output '.skill-downloads/anti-hallucination-research-mode-mrx3y0lj/SKILL.md.part' && mv '.skill-downloads/anti-hallucination-research-mode-mrx3y0lj/SKILL.md.part' '.skill-downloads/anti-hallucination-research-mode-mrx3y0lj/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation
openskills install './.skill-downloads/anti-hallucination-research-mode-mrx3y0lj'

openskills read 'anti-hallucination-research-mode-mrx3y0lj'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/anti-hallucination-research-mode-mrx3y0lj/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
