Agenttune

bernardjhuang/agenttune

Gives your AI agent access to 43 personality tuning files organized by MBTI, Enneagram, DISC, Attachment, and Big Five frameworks, plus 5 inline personality tests. The idea is simple: most frontier models converge on the same interaction style (INTJ when tested), but you probably don't think that way. Load the file that matches how you work and the agent adapts its responses, communication density, and framing to fit. Stack multiple files for higher fidelity. The server exposes the full library over streamable HTTP, so you can programmatically fetch tunings, run tests, or build agents that shift style based on user type. All MIT licensed. Useful if you're building conversational tools where tone and cognitive fit actually matter.

Readme

AgentTune

Editable communication preferences for AI assistants. Browse 43 templates, choose the rules that fit, and review them before adding them to your instructions. A personality label is optional; templates are editorial suggestions, not diagnoses or proven performance improvements.

Website · Preference builder · Library · Research

Start with the behavior you want

  1. Describe your preferred level of detail, tone, structure and pushback in the preference builder, or browse a template below.
  2. Read and edit the actual rules. Your current request and explicit preferences take precedence. No questionnaire framework automatically outranks another.
  3. Add only the reviewed text to the intended conversation, account settings or project instructions. Preserve existing content; use a clearly marked block when editing a shared file.
  4. Reopen the destination to verify storage. Compare several new tasks to assess behavior; saved text alone does not prove that a model will follow it.
  5. To undo, remove only the added block. Do not delete an existing shared instruction file.

Reading a resource does not authorize installation, an external action or a lasting change to preferences. Templates must preserve accuracy, material uncertainty and authorized scope.

Browse templates

  • MBTI-style preferences: 16 templates
  • Enneagram-style preferences: 9 templates
  • DISC-style preferences: 4 templates
  • Attachment-related preferences: 4 templates
  • OCEAN preferences: 10 templates

Combine only rules you want. When two rules conflict, choose explicitly rather than treating a score or framework as an instruction priority. The framework labels are navigation aids, not claims about every person who uses a label.

Optional questionnaires

The current release includes five interactive questionnaire adaptations: MBTI-style, Enneagram, DISC, attachment and IPIP Big Five. The Big Five adaptation returns raw dimension totals and item means. It does not return population percentiles or select instructions automatically. Review the availability and rights record for other instruments. All five questionnaires are available. Their source terms remain separate; availability does not establish unrestricted reuse rights.

See third-party notices before reusing instrument material. Original AgentTune code and preference templates are MIT licensed; that does not make every third-party instrument MIT or commercially reusable.

Versioned content and local scoring

This repository owns the canonical content. The website consumes a pinned release, not a runtime fetch from main. dist/manifest.json gives the release version and SHA-256 of every exported artifact. dist/instruments.json identifies the available definitions, item IDs, response anchors and definition hashes. Every scoring result identifies its instrument and scorer version.

const { score, scoreOrdered } = require('./dist/score.js');
const instrument = require('./dist/instruments.json').find(d => d.route === 'big-five');
const result = score({
  instrumentId: instrument.id,
  instrumentVersion: instrument.version,
  responses: instrument.items.map(item => ({ itemId: item.id, value: 3 }))
});
// result.status === 'complete'; all totals 30 and all item means 3.
// scoreOrdered(id, version, answers) requires the exact complete item order.

Valid partial responses return incomplete, with missing item IDs and no final score. Duplicate/unknown IDs, noninteger/out-of-range values and malformed responses return invalid. Missing answers are never silently imputed. Raw scores are separate from a user's subsequent choice of communication preferences. Keep personal responses local and out of public pull requests.

Browser: load dist/score.js to use AgentTuneScoring. It contains scoring keys for the approved instrument without embedding question wording. The original generic engine is also available separately as dist/engine.js; users are responsible for rights to any definitions they register.

Agent access

The site exposes body-only Markdown at /resources/tunings/<system>/<slug>.md, metadata-rich mirrors via the tuning catalog, and a versioned content manifest. Apply only the body; metadata is for discovery and verification.

The stateless MCP endpoint is https://agent-tune.com/mcp. Its tools are list_tunings, get_tuning, get_test_spec, list_resources, get_resource and get_free_tools. Questionnaire availability is explicit; an unavailable specification must not be treated as an instruction to administer an old questionnaire. MCP retrieves public resources and does not need your questionnaire answers.

Use the installation protocol and platform registry for current destinations. Metadata separates verify.saved_text from verify.behavior; there is no universal compliance probe.

Development and research provenance

Run npm run build and npm test with Node 22 or later. No dependency installation is needed. Edit data/tunings.json, data/contract.md and approved definitions in data/instruments/; do not edit generated copies. npm run check also detects stale generated artifacts. License eligibility, instrument IDs, fixture scores and export parity are release gates.

See the changelog and legacy provenance. Historical questionnaires contained adaptations and undocumented substitutions. Their responses must remain attached to their actual versions. Correcting future instruments does not retroactively correct previous observations. Research about model questionnaire responses is distinct from evidence that a tuning improves task performance.
