aider

A visual reference for how Aider, an AI coding assistant, displays prompts, responses, colors, status details, and approval questions in a terminal. It describes Aider’s simple line-by-line output style.

In plain words
What is it for?
Use it to analyze, document, or reproduce Aider’s command-line behavior, including its prompt, startup information, spinner, and file-approval questions.
Why use it?
It helps developers understand Aider’s interface without assuming knowledge of terminal user-interface frameworks or screen-redrawing techniques.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

aider scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Aider — UI Layout Reference

Agent-specific layout reference for Aider. See agent-ui-analysis.md for shared concepts.

Observed version: v0.86.2 (2026-03-22) Rendering engine: Python readline + rich (no TUI framework) Rendering approach: Sequential CLI output with ANSI colors


Key Characteristics

Aider is the simplest of all supported agents — a sequential CLI tool with no TUI framework, no screen management, no cursor positioning. Output flows linearly top-to-bottom like a normal shell command.

  • No Ink, no Bubble Tea — just Python with rich text formatting
  • Prompt is simple > (green, ANSI 256 color 40)
  • Spinner uses ░█/█░ Knight Rider pattern with backspace overwrite
  • No mode line, no status bar, no panels
  • File approval uses inline Y/N/A/S/D prompts

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

aider is an agent published in the GitHub repository sstraus/tuicommander (125 stars, last pushed 5d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 1,709 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
