**suggestion:** The precedence between auto_exec_args, selected_event, and selected_challenge for the same field names could be made more explicit.

suggestion: The precedence between auto_exec_args, selected_event, and selected_challenge for the same field names could be made more explicit.

Right now the resolution order is:

1. auto_exec_args[prop_name]
2. selected_event for ["ctf_id", "id", "event_id"]
3. selected_challenge for ["challenge_id", "id"].
   If both selected_event and selected_challenge are set and the schema field is just "id", the event ID will be used, which may be surprising in challenge-oriented tools. You could either remove ambiguous keys like bare "id" from these lists, or add logic/comments that clearly tie which ID is chosen to the tool context (event vs challenge).

Suggested implementation:

        for prop_name, prop_details in properties.items():
            value_placeholder = None
            prop_type = prop_details.get("type", "string")

            # Value resolution precedence:
            # 1) auto_exec_args[prop_name]           (highest priority, explicit override)
            # 2) selected_event for ["ctf_id", "event_id"]
            # 3) selected_challenge for ["challenge_id"]
            #
            # Note: we intentionally do NOT auto-fill bare "id" from either selected_event
            # or selected_challenge to avoid ambiguity when both are set. Only explicit,
            # context-specific keys are used here.
            auto_exec_args = getattr(self, "auto_exec_args", {}) or {}

            # 1) Use auto_exec_args if available
            if prop_name in auto_exec_args:
                value_placeholder = auto_exec_args[prop_name]

            # 2) Fall back to selected_event for event-related fields
            elif selected_event is not None and prop_name in ("ctf_id", "event_id"):
                # Prefer the explicit field when present, otherwise fall back to "id"
                value_placeholder = (
                    selected_event.get(prop_name)
                    or selected_event.get("id")
                )

            # 3) Fall back to selected_challenge for challenge-related fields
            elif selected_challenge is not None and prop_name in ("challenge_id",):
                # Prefer the explicit field when present, otherwise fall back to "id"
                value_placeholder = (
                    selected_challenge.get(prop_name)
                    or selected_challenge.get("id")
                )

Provides an interactive terminal interface for browsing CTF events and challenges,

Depending on the rest of the codebase, you may want to:

1. Review any places that relied on auto-filling a bare "id" field from selected_event or selected_challenge and either:
   • Update those tools' schemas to use "event_id" or "challenge_id", or
   • Add explicit logic there if they truly need a generic "id".
2. If there are tools that are strictly event-only or challenge-only and must still auto-fill a bare "id", you can:
   • Add a tool-context flag (e.g., is_event_tool / is_challenge_tool) and branch inside the precedence logic to map "id" appropriately for those tools only.

Plan

Observations

The current implementation in ToolExecutionScreen._generate_template_from_schema has ambiguous precedence rules. When both selected_event and selected_challenge are set and a tool schema contains a bare "id" field, the event ID takes precedence (because it's checked first), which can be surprising for challenge-oriented tools. The suggested fix removes this ambiguity by eliminating bare "id" from auto-fill and introducing auto_exec_args for explicit overrides.

Approach

The implementation will clarify the value resolution precedence in the _generate_template_from_schema method by:

1. Adding support for auto_exec_args as the highest-priority override mechanism
2. Removing ambiguous bare "id" field from auto-fill logic to prevent conflicts when both event and challenge contexts exist
3. Using only explicit, context-specific field names ("ctf_id", "event_id" for events; "challenge_id" for challenges)
4. Adding comprehensive inline documentation explaining the precedence rules

Reasoning

I listed the repository structure, read the main Python file to locate the issue, examined the ToolExecutionScreen class where value resolution occurs, searched for existing auto_exec_args references (none found), reviewed the HTBMCPApp class to understand app state management, and read documentation to understand the project context.

Proposed File Changes

📄 htb_mcp_client.py ^(MODIFY) 🔗

Update the HTBMCPApp.__init__ method to initialize a new auto_exec_args attribute as an empty dictionary. This will serve as a global storage for explicit argument overrides that should take precedence over auto-filled values from selected events or challenges. Initialize it alongside the existing selected_event, selected_challenge, and stored_challenges attributes around line 1071-1073.
Refactor the ToolExecutionScreen._generate_template_from_schema method (lines 309-364) to implement the new value resolution precedence:

1. Add comprehensive documentation comment at the beginning of the value resolution loop (before line 321) explaining the three-tier precedence system:

   • Tier 1: auto_exec_args[prop_name] (highest priority, explicit override)
   • Tier 2: selected_event for event-specific fields ("ctf_id", "event_id" only)
   • Tier 3: selected_challenge for challenge-specific fields ("challenge_id" only)
   • Note: Bare "id" is intentionally NOT auto-filled to avoid ambiguity

2. Replace the existing auto-fill logic (lines 325-344) with the new precedence implementation:

   • First, retrieve auto_exec_args from the app using getattr(self.app, "auto_exec_args", {}) or {}
   • Check if prop_name exists in auto_exec_args and use that value if present (with type conversion if needed)
   • If not in auto_exec_args, check if selected_event is set AND prop_name is in ["ctf_id", "event_id"] (removed "id" from this list)
   • For event fields, prefer the explicit field name (e.g., selected_event.get("event_id")) but fall back to selected_event.get("id") if the explicit field is not present
   • If not an event field, check if selected_challenge is set AND prop_name is in ["challenge_id"] (removed "id" from this list)
   • For challenge fields, prefer the explicit field name but fall back to selected_challenge.get("id") if needed
   • Apply the same type conversion logic (integer/string) as the current implementation

3. Keep the existing default value logic (lines 345-360) unchanged for cases where no auto-fill applies

This change ensures that tools requiring an "id" field must explicitly specify whether they need "event_id" or "challenge_id" in their schema, eliminating ambiguity.
Add a method to ToolExecutionScreen class (after the _generate_template_from_schema method, around line 365) called set_auto_exec_arg that allows setting individual auto-execution arguments. This method should:

• Accept key and value parameters
• Store them in self.app.auto_exec_args[key] = value
• Optionally regenerate the template JSON in the TextArea to reflect the new value

This provides a programmatic way to set explicit argument overrides, which can be useful for future enhancements or testing scenarios where specific argument values need to be forced regardless of context.

### Observations

The current implementation in `ToolExecutionScreen._generate_template_from_schema` has ambiguous precedence rules. When both `selected_event` and `selected_challenge` are set and a tool schema contains a bare "id" field, the event ID takes precedence (because it's checked first), which can be surprising for challenge-oriented tools. The suggested fix removes this ambiguity by eliminating bare "id" from auto-fill and introducing `auto_exec_args` for explicit overrides.

1. Adding support for `auto_exec_args` as the highest-priority override mechanism
2. Removing ambiguous bare "id" field from auto-fill logic to prevent conflicts when both event and challenge contexts exist
3. Using only explicit, context-specific field names ("ctf_id", "event_id" for events; "challenge_id" for challenges)
4. Adding comprehensive inline documentation explaining the precedence rules
