Optimize token usage and context management. Use when sessions feel slow, context is degraded, or you're running out of budget.

Install the context-optimizer skill

A skill is a folder. Copy it into your agent's skills folder and the agent loads it when the task matches its description.

git clone --depth 1 https://github.com/rohitg00/pro-workflow.git /tmp/pro-workflow
mkdir -p ~/.claude/skills
cp -r /tmp/pro-workflow/skills/context-optimizer ~/.claude/skills/context-optimizer
available in every project

In the Claude apps, zip the folder and upload it from the Skills settings. The folder on GitHub

Context Optimizer

Manage your context window and token budget effectively.

Quick Diagnosis

  1. Run /context to check current usage
  2. If > 70% → compact now before it degrades
  3. If > 90% → you're in the "dumb zone", compact immediately

Optimization Strategies

Immediate

Configuration

Set proactive auto-compaction:

{
  "env": {
    "CLAUDE_AUTOCOMPACT_PCT_OVERRIDE": "50"
  }
}

MCP Audit

Keep <10 MCPs enabled, <80 tools total. Each MCP adds overhead to every request.

/mcp          # List active servers
# Disable what you're not using

Prompt Engineering for Token Efficiency

  • Scope your prompts: "In src/auth/, fix the login bug"
  • Provide constraints: "Don't modify the middleware"
  • Give acceptance criteria: "Should return 429 after 5 attempts"
  • Avoid vague prompts: "Fix the code" (forces Claude to read everything)

Subagent Delegation

Heavy operations that generate lots of output should go to subagents:

  • Test suite output → subagent
  • Large file exploration → subagent
  • Documentation generation → subagent
  • Log analysis → subagent

The main session stays clean while subagents handle the volume.

Context Budget Planning

Token Efficiency

Output Reduction (40-60% savings)

  • No sycophantic openers ("Sure!", "Great question!")
  • No closing fluff ("Let me know if you need anything!")
  • No prompt restatement before answering
  • Code first, explanation only if non-obvious
  • Structured output (tables, bullets) over prose
  • ASCII only: -- not em dashes, straight quotes not smart quotes

Behavioral Efficiency

  • One-pass coding: complete solution, test once, stop if green
  • Read before write: never modify unread files
  • No re-reads: don't re-read unchanged files
  • Tool-call budgets: 20 (quick fix) to 80 (large feature)
  • Never iterate more than twice on the same failure

Task Profiles

Switch response style based on context:

  • Coding: code first, minimal explanation, simplest solution
  • Agent/Pipeline: structured output only, no prose, parseable
  • Analysis: finding first, tables over paragraphs, sourced numbers

CLAUDE.md Optimization

  • Root CLAUDE.md: < 60 lines ideal, < 150 max
  • Move package-specific info to package-level CLAUDE.md
  • Move personal preferences to CLAUDE.local.md
  • Remove obvious or rapidly-changing information

When Context Is Degraded

Signs:

  • Claude repeats itself or forgets earlier context
  • Responses become generic or lose project-specific knowledge
  • Tool calls start failing for reasons that worked earlier

Fix:

  1. Manual /compact
  2. If still bad: new session with /resume
  3. For recurring issues: reduce CLAUDE.md size, disable MCPs

  • Aagent-teamsCoordinate multiple Claude Code sessions as a team — lead + teammates with shared task lists, mailbox messaging, and file-lock claiming. Patterns for team sizing, task decomposition, and when to use teams vs sub-agents vs worktrees.
  • Aauto-setupAuto-configure quality gates, hooks, and settings for a new project. Detects project type and sets up appropriate tooling. Use when onboarding a new codebase.
  • Abatch-orchestrationDecompose large-scale changes into independent units and spawn parallel agents in isolated worktrees. Use for migrations, refactors, codemods, and any change touching 10+ files with the same pattern.
  • Cbug-captureCapture a user-reported defect as a durable GitHub issue written in the project's own domain language. Explores the codebase in parallel for context but never leaks file paths or line numbers into the issue. Use when the user reports a bug conversationally, runs a QA pass, or says "file an issue", "log this as a bug", "capture this".
  • Acompact-guardSmart context compaction with state preservation. Saves critical files, task progress, and working state before compaction, restores after. Use before manual compact or when auto-compact triggers.
  • Acontext-engineeringMaster the four operations of context engineering — Write, Select, Compress, Isolate. Manage token budgets, compaction strategies, and context partitioning to keep AI sessions sharp and efficient.
  • Acost-trackerTrack session costs, set budget alerts, and optimize token spend. Use to check costs mid-session or set spending limits.
  • Adesign-engineeringApply interface craft when building or reviewing UI - motion, easing, timing, springs, component feel, and visual foundations. Use when building a component, animation, transition, hover or press state, modal, drawer, toast, or when polishing an interface so it feels right. Says "make this feel better", "add an animation", "polish the UI", "review this component".
  • AdeslopRemove AI-generated code slop, unnecessary comments, and over-engineering from the current branch diff. Cleans up boilerplate, simplifies abstractions, strips defensive code, and in skill-file mode lints SKILL.md files for quality. Use when cleaning up code, simplifying, removing boilerplate, before committing, or when reviewing a skill before promoting it.
  • Adomain-modelingBuild the project's shared language and bounded contexts before writing code, so names stay consistent and the agent stops paraphrasing domain concepts. Produces a CONTEXT.md glossary and decision records. Use at the start of a project or feature, or when the codebase and the people describing it speak different languages.
  • Afile-watcherConfigure file watching hooks to auto-react to config changes, env file updates, and dependency modifications. Use to set up reactive workflows.
  • Aimprove-architectureAudit an area of the codebase and propose the smallest structural moves that improve it - untangle boundaries, kill duplication, fix seams, break cycles. Produces a prioritized plan and decision records, not a rewrite. Use when a codebase feels tangled, hard to change, or is becoming a ball of mud, or when asked to improve or refactor architecture.
