Summary

This PR introduces a .coderabbit.yaml configuration file to improve transparency and control over automated CodeRabbit reviews.

Bug / Issue

There was no existing configuration file for CodeRabbit, which made it hard to understand or modify its default behavior. Additionally, repetitive review_status messages and premature check timeouts were causing disruption during PR reviews.
Issue reference : #2761

Implementation

  • Added a .coderabbit.yaml to the project root.
  • Set review_status: false to disable default status updates in PRs.
  • Increased GitHub check timeout to 180 seconds to avoid early triggers.
  • Enables community review and future version control of CodeRabbit settings.

Testing

As this is a configuration-only change for a GitHub bot, no unit tests are applicable. Successful merging and observing CodeRabbit's updated behavior will confirm correctness.

Additional Notes

No dependencies or downstream impact. Please feel free to suggest other default behaviors or formatting rules to include in the config.

Summary by CodeRabbit

  • Chores
    • Added a new configuration file to adjust review comment behavior and increase review timeout settings.

Walkthrough

A new configuration file named .coderabbit.yaml has been introduced. This file specifies configuration settings including the version, disables automatic review status comments on pull requests, and increases the GitHub check timeout to 180 seconds.

Changes

File(s) Change Summary
.coderabbit.yaml Added new configuration file to set config version, disable review status comments, and adjust timeout.

Poem

In the land of code, a config appears,
With settings set to calm our fears.
No more review comments, quiet as a mouse,
And longer timeouts now grace the house.
With YAML lines so neat and spry,
The rabbit nods as changes fly! 🐇✨

1-10: 💡 Verification agent

🧩 Analysis chain

Configuration file structure looks good, but verify GitHub checks timeout unit.

The configuration file correctly sets up CodeRabbit with version 1 and disables review status comments as requested in the PR objectives. However, there appears to be a potential issue with the GitHub checks timeout configuration.

According to the CodeRabbit schema, the timeout configuration should likely be under reviews.tools.github-checks.timeout_ms and the value should be in milliseconds. The current format might not be recognized correctly.

 version: 1

 # Disable automatic 'review_status' comments on pull requests
 review_status: false

 # Increase GitHub check timeout to avoid premature reviews
-github:
-  checks:
-    timeout: 180
+reviews:
+  tools:
+    github-checks:
+      timeout_ms: 180000

🌐 Web query:

What is the correct format for configuring GitHub check timeout in CodeRabbit's yaml configuration?

💡 Result:

Format for Configuring GitHub Check Timeout in CodeRabbit YAML

To set a timeout for GitHub checks in CodeRabbit's .coderabbit.yaml configuration file, use the following format under the github-checks section:

github-checks:
  enabled: true
  timeout_ms: 90000
  • The timeout_ms parameter specifies the timeout in milliseconds for GitHub checks run by CodeRabbit[1].
  • For example, timeout_ms: 90000 sets the timeout to 90 seconds.

This format is confirmed by public .coderabbit.yaml files in various repositories and aligns with best practices for CodeRabbit configuration[1].

Key points:

  • Place the configuration at the root level of your .coderabbit.yaml file.
  • Ensure that github-checks is enabled for the timeout to be effective.
  • The timeout value must be given in milliseconds.

No additional nesting or parameters are required for this functionality in CodeRabbit YAML[1].

Citations:


Correct root-level GitHub checks timeout configuration

The .coderabbit.yaml schema expects a root-level github-checks key with timeout_ms in milliseconds. Update your config accordingly:

File: .coderabbit.yaml
Lines: 1–10

 version: 1

 # Disable automatic 'review_status' comments on pull requests
 review_status: false

-# Increase GitHub check timeout to avoid premature reviews
-github:
-  checks:
-    timeout: 180
+# Increase GitHub check timeout to avoid premature reviews
+github-checks:
+  enabled: true
+  timeout_ms: 180000

Replace the nested github.checks.timeout (in seconds) with the root-level github-checks.timeout_ms (in milliseconds).

660-715: 🛠️ Refactor suggestion

Scatter omits size & color, defeating custom portrayal

ax.scatter is called without s= (size) or c=/color=, so all agents appear with
Matplotlib defaults. The portrayal data you painstakingly collect never reaches the plot.

Add the missing parameters and vectorise to avoid per-marker loops when not necessary:

             ax.scatter(
                 x[logical],
                 y[logical],
                 marker=mark,
                 zorder=z_order,
+                s=np.array([a.size for a in arguments])[logical],
+                c=np.array([a.color for a in arguments])[logical],
                 edgecolors=np.array(edgecolors)[logical],
                 linewidths=np.array(linewidths)[logical],
                 alpha=np.array(alpha)[logical],
                 **kwargs,
             )

Optionally, consider a single call to scatter when all markers are identical to improve performance.

🧹 Nitpick comments (3)
mesa/visualization/AgentPortrayalStyle.py (1)

1-29: Add a module docstring to explain the purpose of this new class.

This is a well-structured dataclass that encapsulates agent portrayal attributes in a more consistent way than using dictionaries. The to_dict method provides backward compatibility with existing code.

Add a module-level docstring to explain the purpose of this file and how the AgentPortrayalStyle class fits into the visualization system.

485-530: Redundant pre-allocation & unused scatter_data

scatter_data and the earlier s, c, marker, … lists are built but never consumed
(Ruff F841). After the fix in _scatter, you can delete the whole pre-allocation block:

-    # Pre-allocate all needed fields in one pass
-    ...
-    linewidths.append(a.linewidths)
-
-    # Convert data for plotting
-    scatter_data = {
-        "s": [a.size for a in agent_data_list],
-        ...
-    }

12-12: ⚠️ Potential issue

Fix type mismatch in size parameter.

The size parameter is provided as a string "10", but the AgentPortrayalStyle class defines size as an integer with default value 30.

This type mismatch could cause errors when the visualization tries to use this value. Change the size parameter to an integer:

-    return AgentPortrayalStyle(color="red", marker="o", size="10")
+    return AgentPortrayalStyle(color="red", marker="o", size=10)

mesa/visualization/components/matplotlib_components.py (1)

38-45: ⚠️ Potential issue

Lambda wrapper introduces infinite recursion and type-mismatch

The lambda you pass to SpaceMatplotlib ignores its agent argument and immediately calls collect_agent_data(...), which itself calls agent_portrayal(agent) again inside its loop.
Flow:

  1. draw_orthogonal_grid()collect_agent_data(space, lambda)
  2. collect_agent_data loops over every agent
  3. For each agent calls the lambda → second collect_agent_data(...)
  4. Inner call returns a list, not a single AgentPortrayalStyle, so the outer call tries to access .color, .size, … on a list ⇒ AttributeError.

Besides the recursion, the return type now violates the expectation of collect_agent_data, breaking all downstream drawing functions.

-        return SpaceMatplotlib(
-            model,
-            lambda agent: collect_agent_data(model.space, agent_portrayal),
+        # pass the original callable – the drawing helpers will call
+        # collect_agent_data themselves

47-122: 🛠️ Refactor suggestion

collect_agent_data should return a list of AgentPortrayalStyle, not a dict

All callers (draw_* helpers and _scatter) treat the result as an iterable of objects.
Current implementation builds numpy arrays and finally returns a dict, producing:

  • TypeError in _scatter which asserts every element is AgentPortrayalStyle.
  • Dead code (color_list, size_list, …) that is never used elsewhere.
  • False Ruff warnings for unused variables.

Proposed minimal fix:

@@
-    color_list = []
-    ...
-    loc_list = []
+    # we only need a single container
+    agent_data_list: list[AgentPortrayalStyle] = []

@@
-        color_list.append(portrayal.color)
-        ...
-        loc_list.append(portrayal.loc)
+        agent_data_list.append(portrayal)

-    # Convert all to numpy arrays
-    return {
-        "color": np.array(color_list),
-        ...
-        "loc": np.array(loc_list),
-    }
+    return agent_data_list

This aligns the function with its advertised behaviour and the expectations of every caller.
