Closes: #771

This PR resurrects #772 which was closed due to author inactivity.

Description

Replace the single-threshold ToolRepetitionDetector with a two-tier system:

  • Soft block (default 2nd identical call): the tool is not executed and the model receives an error asking it to justify the repeat. The user is not involved and the counter keeps incrementing toward the hard limit.
  • Hard stop: execution stops and the user is asked for guidance (previous behavior).

Test Procedure

Tell a model to call the same command multiple times. See how it can't execute 3rd command and starts to using different variations of it.

📝 Summary

Summary by CodeRabbit

  • New Features
    • Added a configurable soft limit for consecutive identical tool calls, defaulting to 2. Set it to 0 to disable the soft limit.
    • When reached, the repeated call is blocked and the AI is asked to justify retrying. Reaching the existing hard limit still prompts for user guidance.
    • Added the setting to advanced provider settings, with translated labels and guidance.

Walkthrough

The change adds a configurable soft threshold for repeated identical tool calls. It updates detector outcomes, assistant-message handling, provider settings, task construction, and the settings UI. A migration assigns the default soft limit to existing provider configurations that do not have one.

Changes

Tool Repetition Limits

Layer / File(s) Summary
Define, persist, and pass the soft limit
packages/types/src/provider-settings.ts, packages/types/src/provider-settings/common.ts, packages/types/src/task.ts, src/core/config/ProviderSettingsManager.ts, src/core/config/__tests__/ProviderSettingsManager.spec.ts, src/core/task/Task.ts, src/core/task/__tests__/Task.spec.ts, src/core/webview/ClineProvider.ts, src/eslint-suppressions.json
Provider and task types include the soft limit, which defaults to 2. Provider initialization migrates missing or null values. Task creation passes the configured value to Task, which updates the detector when its API configuration changes. Tests cover migration and task-limit updates.
Implement soft and hard detector outcomes
src/core/tools/ToolRepetitionDetector.ts, src/core/tools/__tests__/ToolRepetitionDetector.spec.ts
ToolRepetitionDetector returns allow, soft_block, or hard_block. Soft blocks retain the repetition count; hard blocks reset it. Tests cover thresholds, disabled limits, limit updates, and repeated-call parameters.
Route detector outcomes in assistant messages
src/core/assistant-message/presentAssistantMessage.ts, src/core/assistant-message/__tests__/*, src/i18n/locales/*/tools.json
Soft blocks produce an error tool result without a user prompt. Hard blocks use the user-guidance flow. Tests cover block paths, feedback, and allowed tool execution. Locales add soft-block messages.
Configure and constrain the soft limit
webview-ui/src/components/settings/ApiOptions.tsx, webview-ui/src/components/settings/ToolRepetitionLimitControl.tsx, webview-ui/src/components/settings/toolRepetitionLimits.ts, webview-ui/src/components/settings/__tests__/*, webview-ui/src/components/ui/slider.tsx, webview-ui/src/i18n/locales/*/settings.json
The settings UI adds a soft-limit slider and clamps its value below an enabled hard limit. Tests cover default values, updates, and clamping. Locales add the setting label and description.

Merge Risk: ⚪ Minimal · up to f1a70

The identified settings and repetition-limit concerns are addressed at the current head. No actionable merge-blocking risk remains after normal checks.

Security Architecture Review

Security architecture risk: 🔵 Low · up to f1a70

Early blocking adds a safeguard without granting additional permissions, while the existing hard-stop behavior remains. No introduced security weakness was established in the inspected paths, but interrupted settings persistence and broader execution coverage remain unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The directly inspected exposure is task-local: generated tool calls influence repetition state and whether existing tool dispatch proceeds. Provider settings affect tasks that consume the selected configuration. These changes do not establish broader tenant, service, credential, or environment authority; exhaustive downstream tool capabilities were not assessed.

Security Findings and Attack Paths

  • observed — Profiles with a legacy hard threshold of zero and no explicit soft threshold remain unlimited after migration. The base detector already disabled repetition blocking for zero, so this is preserved exposure, not an introduced or worsened security concern.

Trust Boundaries and Controls

  • observed — The soft-block path returns feedback rather than execution authority. It uses the existing per-call result handling and task-level duplicate-result protection. Stored provider profiles are parsed and individual configurations validated before migration and task consumption.

Resilience and Maintainability Implications

  • observed — The existing abort guard and presentation lock serialize streamed processing of task-owned repetition state. Completed blocked calls advance through the normal content-index flow instead of being redispatched on the next streaming update.

Full details: Regression Evidence

Explanation

The PR adds a durable, visible soft-limit slider to the advanced provider settings in ApiOptions.tsx and introduces ToolRepetitionLimitControl.tsx. The new Vitest tests cover text and behavior, but they mock the slider; the interaction tests also mock the slider. The changed files and existing settings visual tests contain no Playwright snapshot for this provider-settings surface. This misses the required visual evidence for the changed UI.

With the defaults (hard 3, soft 2), a repeat after the soft block hits the hard limit, and the tool never runs. Does this text overpromise by saying the model can call it again if it explains why? Could it say that repeating will stop the task and ask the user?

This is nudging the model to think loudly why it really needs to call this again. I found that if model is forced to think it then will choose a different solution because the repeats themselves didn't make sense in the first place.

// model asking it to justify repeating the call (or try a
// different approach). The detector keeps counting so continued
// repetition will eventually escalate to a hard block.

This check has no exemptions, so a repeated update_todo_list, attempt_completion, ask_followup_question or execute_command is now rejected from the 3rd identical call. Before this PR the first block came at the hard limit. Is that intended, or should some of these tools be exempt?

Yes, this is intended. The point is to allow the model to try something different instead of hitting the hard block and then stopping execution waiting for the user to resolve things.

Replace the single-threshold ToolRepetitionDetector with a two-tier system:

- Soft block (default 2nd identical call): the tool is not executed and the
  model receives an error asking it to justify the repeat. The user is not
  involved and the counter keeps incrementing toward the hard limit.
- Hard stop: execution stops and the user is asked for guidance (previous behavior).
