Drilldown

Presentation & Onboarding — 17 / 25

Criterion	Max	Score	Notes
Configuration-mode examples	12	12	README provides examples for basic usage, custom provider, and different AI providers with sensible defaults. Each major mode (different providers, custom configuration) is documented.
Coder-context framing	8	5	README mentions "Run Aider AI pair programming in your workspace" and "seamless Coder Tasks Support" but lacks detail on how Coder fits in the flow or what the module adds on top of base Coder functionality. AgentAPI integration is mentioned but not explained in Coder context.
Visual preview	5	0	No image, GIF, or video in README. Only an icon reference in frontmatter.

Agent Integration — 15 / 25

Criterion	Max	Score	Notes
AI governance	10	5	README references "Coder AI Agents Guide" link but does not document AI Gateway or Agent Firewall support. The module uses AgentAPI but governance mechanisms are not explained. Only partial/implicit support documented.
Dashboard entry point	5	5	Module uses coder_app via the agentapi submodule with configurable web_app_display_name, cli_app, and related settings. Both web and CLI apps are supported and documented.
Session continuity	5	0	No documentation of session resumption, persistent session managers (tmux, screen, boo), or continuing existing agent sessions across reconnects.
Managed configuration	5	5	Documented support for managed configuration via base_aider_config variable (YAML format), system_prompt, ai_prompt, and workdir configuration. Examples show configuration management.

Credential Hygiene — 18 / 20

Criterion	Max	Score	Notes
Secrets marked sensitive	16	14	The api_key variable is marked sensitive = true in main.tf. However, README examples show api_key = var.api_key and api_key = var.gemini_api_key which reference variables but the variable declarations themselves show sensitive = true. The examples avoid literal inline secrets but demonstrate the pattern. Capping at 14 for minor ambiguity in example presentation.
Non-hardcoded auth path	4	4	README shows using Terraform variables for API keys, which is a standard non-inline approach. The module supports multiple providers with appropriate environment variable mapping.

Restricted-Environment Readiness — 0 / 20

Criterion	Max	Score	Notes
Mirrorable artifact source	10	0	No module variable overrides the download URL for Aider or pipx. The install script hardcodes pipx install --force aider-install and aider-install with no URL override mechanism. AgentAPI has version control but not URL override for its binary source.
Bring-your-own binary	5	0	No documented way to skip installation when Aider is pre-installed. The install_aider variable exists but is not documented in README, and even when false, the install script still runs install_aider function unconditionally based on the script logic.
Egress transparency	3	0	No dedicated README section enumerating external endpoints. PyPI (for pipx/aider), GitHub (for agentapi binary), and AI provider endpoints are contacted but not documented in a network/offline/air-gapped section.
Runs without sudo	2	0	The install.sh script explicitly uses sudo apt-get install -y pipx on line 23, requiring root for core functionality (installing the package manager needed for Aider). No fallback or non-sudo path documented.

Engineering Quality — 8 / 10

Criterion	Max	Score	Notes
Input quality	6	4	Most inputs have descriptions. The ai_provider has validation. However, several inputs lack validation where appropriate (e.g., model has no validation, workdir has no path validation, agentapi_version has no format validation). Defaults are generally sensible.
Test coverage	4	4	Clear testing story with both .tftest.hcl (covers variable validation and configuration) and TypeScript tests in main.test.ts (covers end-to-end behavior including install, API key handling, custom folders, pre/post scripts). Business logic and integration both tested.

Overall — 58 / 100
