Opportunities — the stories that would move this product's scores, from its own judged verdictsOpportunitiestop 8 of 48 stories with headroom

What would move Aider’s scores — derived from its own judged verdicts, biggest headroom first. Each line quotes what the judge found missing; shipping it (or evidencing it publicly) is the fix.

  1. Agenticness — how well agents can access and operate the productPlug MCP servers into this product so it can use their tools

    nonemoves agent-readyimpact 45

    No evidence in the pack that Aider supports connecting to MCP servers or using MCP-provided tools; its documented extensibility is via slash commands, scripting API, linters/tests, and web/voice input, not MCP.

  2. Agenticness — how well agents can access and operate the productConnect an agent via an official MCP server

    nonemoves agent-readyimpact 45

    Aider is a coding agent itself (a CLI/chat tool that edits code), which per the rules places serving as an MCP server outside its natural role; however no evidence shows it running as an MCP server or exposing an official MCP endpoint.

  3. Autonomy agents — stories about autonomy agents in this arenaDelegate longer-running coding tasks to run in the background in an isolated cloud environment

    nonemoves PA Scoreimpact 30

    Aider is a local CLI/scripting tool that runs synchronously in the developer's own environment (terminal, IDE, or scripted via Coder.create); there is no evidence of a cloud-hosted, isolated execution environment or background/async task delegation.

  4. Ecosystem — integrations, plugins, and third-party ecosystem storiesConnect the agent to workflow tools like Jira, Slack, and Google Drive to extend its context

    nonemoves PA Scoreimpact 30

    Aider's documented features cover file editing, git integration, web scraping, and voice input, but there is no evidence of any integration with workflow tools like Jira, Slack, or Google Drive.

  5. Code generation — quality of generated code — correctness, style, fit to the codebaseReceive inline code completions and next-edit suggestions as I type

    nonemoves PA Scoreimpact 30

    Aider is a chat-driven CLI/git-based pair-programming tool; even its closest feature, --watch-files mode, only triggers edits when the user writes explicit '# ...

  6. Code generation — quality of generated code — correctness, style, fit to the codebaseTurn a tracked issue into a complete pull request end-to-end

    nonemoves PA Scoreimpact 30

    Aider's documented workflow covers editing files, committing changes locally with descriptive messages, and running tests/lint — but there is no evidence of reading a tracked issue (e.g., GitHub/GitLab issue) or automatically opening a pull request.

  7. Codebase understanding — how deeply the tool maps your repo — cross-file context, architecture awareness, historyAdd a project instructions file to set coding standards and conventions the agent follows

    nonemoves PA Scoreimpact 30

    The evidence pack documents aider's config file (.aider.conf.yml) for command-line options and repo-map features, but contains no mention of a dedicated project instructions/conventions file (e.g.

  8. Privacy posture — data-handling and privacy storiesPrevent my data from being used to train AI models

    nonemoves PA Scoreimpact 30

    No evidence in the pack addresses data usage/training opt-outs, privacy policy, or data retention controls for Aider or the LLM providers it connects to; Aider primarily relies on third-party LLM APIs whose training-data policies aren't documented here.
