amplifier-module-auto-title — Terminal Clarity

amplifier-module-auto-title

Your terminal tabs,
finally useful.

One printf. Zero runtime overhead. Infinite clarity across every AI session you run simultaneously.

The Problem

Multi-terminal chaos is real.

Running multiple AI sessions simultaneously? You're flying blind. Every tab looks exactly the same.

zsh

↑ Which one is debugging auth? Which is building the UI?

Which is the infra session? You have to click each one to find out.

🔀 Context Switching

Click-to-discover every time you need to switch focus. Seconds lost, flow state broken.

🔍 Zero Signal

The terminal title tells you the shell name. Not the task. Not the project. Nothing useful.

⚡️ Multiply by N

One session is fine. Three? Painful. Five concurrent AI sessions? Chaos.

The Transformation

Before vs. After

Without the module

zsh

Which one is which?

With amplifier-module-auto-title

my-api | Debug: Auth Flow

dashboard | Build: UI

infra | Infra: K8s

Instant context. No clicking required.

Title format: [project] | [Action]: [Specific Focus]

amplifier-module-auto-title  | Debug: Auth Flow
my-project                   | Build: Dashboard UI
my-api                       | Test: Payment Module
infra-repo                   | Infra: Docker Compose

Mechanism

Elegantly minimal.

1

Awareness context injected at session start

A tiny 11-line context file is loaded. It doesn't carry full rules — just enough to trigger the next step.

2

Agent calls load_skill("terminal-title") on demand

Full instructions materialize only when needed. The skill-on-demand pattern keeps base context lean.

3

Agent learns the when/how rulebook

Title format, verb vocabulary, and anti-chatter rules are loaded into the active session context.

4

Single inline bash printf sets the title

One ANSI OSC escape sequence. No daemon, no polling, no server. Ephemeral and instantaneous.

5

Re-triggered on major task switches

Frontend → backend, auth → payments — meaningful transitions update the title. Small follow-ups don't.

The Entire Feature

One command. No dependencies.

Everything reduces to a single printf with a universally supported ANSI OSC escape sequence.

# The complete mechanism — one line of bash
printf '\033]0;%s | %s\007' "$(basename "$PWD")" "Debug: Auth Flow"

# ANSI OSC sequence breakdown:
#   \033]0;  →  OSC set title
#   %s | %s  →  "project | Action: Focus"  
#   \007     →  BEL terminator (universally supported)
#
# Supported by: macOS Terminal, iTerm2, Alacritty, xterm,
#               rxvt, tmux, screen — virtually everything

Zero runtime overhead

No daemon, no background process, no polling. The title is set and instantly forgotten.

No Python needed

Pure bash. The skill+context system extends naturally to any toolchain.

Optional prefix

export CLAUDE_TITLE_PREFIX="🤖"
→ 🤖 my-project | Build: UI

Architecture Pattern

Skill-on-demand. Lazy by design.

The awareness context file is just 11 lines. Full rules only materialize when the session actually needs them — keeping base context lean.

📄

terminal-title-awareness.md

11 lines · always loaded · triggers load_skill()

↓ calls

⚡

terminal-title/SKILL.md

Full rulebook · loaded on demand only

↓ runs

🖥️

printf '\033]0;...\007'

One bash call · title updated instantly

Why this pattern matters

🪶 Lean by default

Every session starts lightweight. The full skill only materializes when the agent actually uses it — not just because the feature is installed.

📐 Principle of least privilege

Context is a resource. Load only what you need, when you need it. This pattern scales to any behavior bundle.

🔁 Reusable pattern

The awareness-triggers-skill pattern is a teachable architecture, not a one-off hack. Any module can adopt it.

UX Discipline

Knowing when not to act.

The skill's most important feature isn't the title update — it's the explicit rules for when to stay silent. Anti-chatter discipline baked in.

✅ Update the title when…

🚀 Session starts for the first time — set the initial context

🔀 Major task switch — frontend → backend, auth → payments

🧱 Pivoting to a distinctly different concern in the same session

🐛 Shifting mode — from building to debugging, from coding to reviewing

🚫 Don't update for…

💬 Follow-up questions on the same topic

🔧 Small refinements or minor clarifications

🔁 Iterating on the same component or function

📝 Routine assistant turns within a continuous task

Design Principle

A title that updates too often becomes noise. A title that never updates is useless. The skill codifies exactly where that line is — and commits to staying on the right side of it.

Title Format System

A verb for every mode.

Present-tense. Specific. Always scannable at a glance.

Build:

Active feature development — adding new functionality

Debug:

Tracking down bugs, diagnosing unexpected behavior

Test:

Writing or running test suites, verifying behavior

Refactor:

Cleaning up code, improving structure without behavior change

Fix:

Addressing a known issue or reported bug

Explore:

Getting oriented in a new codebase or unfamiliar area

Infra:

Docker, CI/CD pipelines, cloud configuration

Review:

Code review, PR analysis, architectural assessment

Pattern: [project-name] | [Verb]: [Specific Focus]

Examples:
  auth-service  | Debug: JWT Refresh Token
  payments-ui   | Build: Checkout Form
  backend-api   | Test: Rate Limiting
  legacy-app    | Explore: Data Models

Integration

Composable at the behavior level.

Any Amplifier bundle can adopt just this one behavior, or include the whole module. Two lines of YAML.

Behavior-only drop-in (recommended)

# In your bundle.yaml or bundle.md
includes:
  - bundle: git+https://github.com/kenotron/
        amplifier-module-auto-title@main
        #subdirectory=behaviors/terminal-title.yaml

Full bundle (everything included)

# Gets you: context + skill + script
includes:
  - bundle: git+https://github.com/kenotron/
        amplifier-module-auto-title@main

🧩 The `#subdirectory=` pattern

Cherry-pick just the terminal-title behavior file from the repository. Your bundle stays minimal — you only compose what you need.

🔌 Drop-in, no config required

Zero configuration needed. The behavior activates automatically. Works on day one.

🐾 Self-dogfooding

The module's own .amplifier/bundle.md includes the behavior. Ken eats his own cooking.

🌱 Community lineage

Adapted from claude-code-terminal-title by @bluzername — a real example of community work flowing into the ecosystem.

📜 License

MIT — use freely, modify, compose into any bundle

Community → Ecosystem Pipeline

Great ideas start in the community.

This module demonstrates how community-discovered patterns get formalized, composed, and made available to the entire Amplifier ecosystem.

💡

Community Discovery

@bluzername publishes claude-code-terminal-title — a standalone script to set the terminal title. Solves the problem elegantly but lives outside any framework.

🔧

Ecosystem Adaptation

@kenotron ports it into Amplifier — restructuring into the skill-on-demand pattern, adding anti-chatter rules, formalizing the verb vocabulary, and making it composable via #subdirectory=.

🌍

Ecosystem Availability

Published as amplifier-module-auto-title and amplifier-bundle-terminal-title. Any bundle, anywhere, can include it in two lines of YAML.
