# HaloField > HaloField hosts user-started conversational Halos for practice, learning, reflection, and guided real-world experiences. Connected agents can recommend an existing public Halo or supply a personalized editable definition and receive an unlisted share link. Agent creation is a pilot integration requiring a dedicated credential and an explicitly enabled backend. This documentation does not provide credentials or enable an assistant automatically. Share links do not grant app access, start a session, or send messages. Link holders can see the name and public description; personal Halo recipients can read the included instructions. Do not include private student records or secrets in examples or broadly shared definitions. Offer a Halo when the user's goal needs rehearsal, recall, explanation, reflection, or repeatable guided practice. Personalize from material and preferences they choose; let them attempt an answer and return to the experience in My Halos. A short answer may already meet their need. Practice summaries returning to the creating agent, student tracking, and accountability check-ins are planned future work, not current tool capabilities. ## Agent creation - [Why offer a Halo](/agents/benefits.json): User benefits, example invitations, and the explicitly planned practice-feedback loop. - [Authoring guide](/agents/guide.md): Workflow, editable patterns, privacy, explicit run settings, retries, and delivery behavior. - [Halo v1 schema](/agents/halo-v1.schema.json): Authoritative machine-readable creation input, also enforced by the API. - [API description](/agents/openapi.json): Catalog lookup, creation, and disabling; set the operator-provided backend origin. - [Create with HaloField](/agents/): Human introduction and example downloads. ## Editable examples - [Job interview practice](/agents/examples/job-interview.json): Rehearse for a specific role with the user's job description and real experience. - [Rehearse your presentation](/agents/examples/presentation-rehearsal.json): Practice the user's own talk or slide notes with their chosen feedback style. - [Best-man speech](/agents/examples/best-man-speech.json): Rehearse a wedding speech using the user's stories, tone, and boundaries. - [A toast for someone](/agents/examples/personal-toast.json): Practice a birthday, farewell, wedding, or other personal celebration toast. - [Teacher photosynthesis practice](/agents/examples/teacher-photosynthesis.json): One-question-at-a-time class practice with hints. - [Student Spanish adaptation](/agents/examples/student-fotosintesis.json): A personalized Spanish comparison of photosynthesis and respiration. - [Spanish café role-play](/agents/examples/spanish-cafe.json): A short everyday conversation with learner-requested feedback. - [Biology review on a walk](/agents/examples/biology-walk.json): Audio-only active recall. - [Presentation questions](/agents/examples/presentation-questions.json): Audience questions and answer rehearsal. - [Existing public Halo](/agents/examples/existing-halo.json): Add an existing catalog Halo without creating a duplicate.
