# MentorActionReasons class > The MentorActionReasons class of Novior.MentorAgent.Abstractions.Models: The reason codes of MentorActionDecision.ReasonCode. They stay the same from one… - URL: https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionreasons - Verified with: MentorAgent 1.2.0 - Last updated: 2026-10-27 - Packages: Novior.MentorAgent.Abstractions The reason codes of [`MentorActionDecision.ReasonCode`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractiondecision#reasoncode). They stay the same from one version to the next; a new one comes only in a minor version, and the CHANGELOG says so. ## Definition Namespace: `Novior.MentorAgent.Abstractions.Models`. Package: `Novior.MentorAgent.Abstractions`. `public static class MentorActionReasons` ```shell dotnet add package Novior.MentorAgent.Abstractions ``` ## Fields ### `Allowed` `public const string Allowed = "allowed"` [`MentorActionOutcome.Allowed`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome): the action requires no role, or the user holds one, and every `IMentorActionPolicy` lets it through. ### `AuthCheckFailed` `public const string AuthCheckFailed = "auth-check-failed"` [`MentorActionOutcome.Denied`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome): reading the user threw. ### `AuthNotConfigured` `public const string AuthNotConfigured = "auth-not-configured"` [`MentorActionOutcome.Denied`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome): the action requires a role and the host has no `AuthenticationStateProvider`. ### `AutoApproved` `public const string AutoApproved = "auto-approved"` [`MentorActionOutcome.Allowed`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome): in Native mode, an auto-approval rule let an action that asks for confirmation run without asking. ### `Completed` `public const string Completed = "completed"` [`MentorActionOutcome.Executed`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome): the action ran. ### `ConfirmationTimeout` `public const string ConfirmationTimeout = "confirmation-timeout"` [`MentorActionOutcome.Rejected`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome): nobody answered the confirmation within `ConfirmationTimeout`, so the action did not run. ### `Exception` `public const string Exception = "exception"` [`MentorActionOutcome.Failed`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome): the action threw. ### `LoginRequired` `public const string LoginRequired = "login-required"` [`MentorActionOutcome.Denied`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome): the action requires a role and nobody is signed in. ### `NobodyToConfirm` `public const string NobodyToConfirm = "nobody-to-confirm"` [`MentorActionOutcome.Denied`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome): the action, or a policy, asks for confirmation and nobody can give it — a task from another agent, a call to the MCP server. A policy's reason is in [`MentorActionDecision.Detail`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractiondecision#detail). ### `NotAuthorized` `public const string NotAuthorized = "not-authorized"` [`MentorActionOutcome.Denied`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome): an `IMentorActionPolicy` does not allow this user the action. ### `Operator` `public const string Operator = "operator"` [`MentorActionOutcome.ConfirmationRequested`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome), [`MentorActionOutcome.Confirmed`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome), [`MentorActionOutcome.Rejected`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome): the user was asked, and answered. ### `Policy` `public const string Policy = "policy"` [`MentorActionOutcome.Blocked`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome): an `IMentorActionPolicy` stopped the call. [`MentorActionOutcome.ConfirmationRequested`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome): a policy asked for the confirmation, which the action does not ask for itself; the answer is then [`MentorActionReasons.Operator`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionreasons#operator)'s, as for any other. ### `PolicyException` `public const string PolicyException = "policy-exception"` [`MentorActionOutcome.PolicyFailed`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome): an `IMentorActionPolicy` threw. ### `PolicyTimeout` `public const string PolicyTimeout = "policy-timeout"` [`MentorActionOutcome.PolicyFailed`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome): an `IMentorActionPolicy` did not answer within `ActionPolicyTimeout`. ### `RateLimited` `public const string RateLimited = "rate-limited"` [`MentorActionOutcome.Denied`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome): the caller is over `RateLimitPerUser` (MCP server). ### `ResultWithheld` `public const string ResultWithheld = "result-withheld"` [`MentorActionOutcome.Executed`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome): the action ran, and `OnToolResult` threw, so its result was withheld. The MCP server's caller gets an error result. ### `RoleMissing` `public const string RoleMissing = "role-missing"` [`MentorActionOutcome.Denied`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome): the user holds none of the roles. ### `SessionEnded` `public const string SessionEnded = "session-ended"` [`MentorActionOutcome.Stopped`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome): the session ended — the circuit, the hub connection or the request closed. ### `Stop` `public const string Stop = "stop"` [`MentorActionOutcome.Stopped`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome): Stop, `/mentor/cancel`, the MCP client cancelled the call, or the caller cancelled the A2A task — also after the confirmation, before the action started. ### `TurnEnded` `public const string TurnEnded = "turn-ended"` [`MentorActionOutcome.Stopped`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome): in Native mode, the turn ended before the action could run — the run failed after the confirmation, or the turn gave up after too many rounds of approvals. ### `Withheld` `public const string Withheld = "withheld"` [`MentorActionOutcome.Denied`](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome): the MCP server does not publish the action — it asks for confirmation, a predicate keeps it back, or it requires roles and no `McpCallerPrincipal` is set. --- - Previous: [MentorActionOutcome enum](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionoutcome.md) - Next: [MentorActionRequest record](https://docs.mentoragent.net/api/novior-mentoragent-abstractions-models/mentoractionrequest.md)
