# Denial Tracking & Permission Escalation

> Track repeated tool denials and auto-escalate to blanket permission prompts or fallback strategies, preventing wasted iterations in non-interactive contexts.

## Use when

- Agent runs in non-interactive or background mode
- Permission prompts are auto-denied by default
- Agent retries blocked tools without progress

## Avoid when

- All tools are pre-authorized
- Agent runs only in interactive mode with attentive user

## Problem

When agents run in non-interactive contexts (background jobs, CI/CD pipelines, headless mode), every permission prompt is typically auto-denied. If the agent keeps attempting the same blocked tool, it wastes its iteration budget retrying an action that will never succeed. This leads to silent failures, stalled tasks, and burned compute with no progress.

Even in interactive mode, a user who repeatedly denies a specific tool creates the same loop: the agent tries, gets denied, tries again with a slightly different argument, and gets denied again.

## Solution

Maintain a per-tool denial counter scoped to the current conversation. After a configurable threshold of denials (typically 3), escalate instead of retrying:

- **Interactive mode:** Prompt the user for blanket permission ("Bash has been denied 3 times. Allow all Bash for this session?").
- **Non-interactive mode:** Switch to a fallback strategy (use a different tool, skip the step, or abort with a clear error).

```pseudo
class DenialTracker:
    counts: Map<string, number>   // tool_name -> denial count
    threshold: number = 3

    on_denial(tool_name):
        counts[tool_name] = (counts[tool_name] || 0) + 1
        if counts[tool_name] >= threshold:
            return ESCALATE
        return RETRY_DIFFERENT

    on_allow(tool_name):
        counts.delete(tool_name)   // reset on success
```

When escalation triggers and the user grants blanket permission, add the tool to `alwaysAllowRules` for the remainder of the session and reset the counter.

```mermaid
graph TD
    A[Tool Denied] --> B[Increment Counter]
    B --> C{Counter >= Threshold?}
    C -- No --> D[Retry with Different Approach]
    C -- Yes --> E{Interactive?}
    E -- Yes --> F[Prompt: Allow all for session?]
    E -- No --> G[Switch to Fallback Strategy]
    F -- Granted --> H[Add to alwaysAllow & Reset]
    F -- Denied --> G
    H --> I[Continue Execution]
    G --> J[Skip / Use Alternative / Abort]
```

## How to use it

- **Per-conversation tracking:** Denial counters reset at session start. No state persists across conversations.
- **Subagent isolation:** Subagents maintain their own local denial tracking since their state writes may be no-ops in the parent.
- **Configurable thresholds:** Different tools may warrant different thresholds. Shell access might escalate after 2 denials; file reads after 5.
- **Combine with permission tiers:** Pair with a multi-layer permission system so that escalation grants the minimum viable scope (e.g., allow Bash but only for read-only commands).

**When to apply:**

- Background or headless agent runners where prompts are auto-denied
- CI/CD agents that need certain tools to complete their task
- Long-running interactive sessions where approval fatigue is likely

## Trade-offs

- **Pros:** Prevents wasted iteration loops; surfaces the real blocker early; reduces approval fatigue in interactive mode; trivial to implement (a counter and a branch).
- **Cons:** Blanket session permissions widen the attack surface after escalation; threshold tuning requires experimentation; fallback strategies must be defined per tool, adding configuration overhead.
