name: token-efficiency description: >- Cross-platform token audit and optimization for AI coding agents (Cursor, Codex, Claude Code, Hermes, Windsurf, Cline, OpenClaw, Gemini CLI, Aider). Scans always-on context, MCP tools, skills; ranks ROI fixes; installs L0-L3 rules; shrinks large tool outputs. Use for save tokens, token audit, context bloat, MCP prune, reduce API cost, agent efficiency, payload shrink. disable-model-invocation: true

Token Efficiency v0.3.1

Prime directive: Audit before adding rules. Rules are fixed tax too.

Capability promise: Save waste, not intelligence. Guardrails ship with every rule install.

学员 / 讲师

# 讲师打包
python3 scripts/package_release.py   # → dist/token-efficiency-0.3.1.zip

# 学员解压后
bash install.sh
python3 scripts/setup_student.py

Quick commands

# Install skill globally (once)
bash install.sh
# or: python3 scripts/install_skill.py --write

# Audit + optional ledger
python3 scripts/audit.py --project . --with-ledger

# Fix auto-invoke skills (L0)
python3 scripts/fix_skills.py --list
python3 scripts/fix_skills.py --write --keep skill-a,skill-b

# Compress bloated CLAUDE.md (L0)
python3 scripts/compress.py CLAUDE.md --write

# Shrink large tool output (L2)
python3 scripts/shrink.py build.log --vault -o build.log.shrunk

# Before/after savings report
python3 scripts/perf.py --save-baseline
python3 scripts/perf.py --compare-baseline

# Install rules to project
python3 scripts/install.py --write --agents cursor,claude-code,hermes,openclaw,codex --levers 1,2,3

Windows: replace python3 with python or py -3.

Workflow

1. AUDIT — scripts/audit.py → fixed tax + duplicates + ROI fixes
2. FIX L0 — MCP prune, skill on-demand, compress, dedup
3. FIX L1/L2/L3 — scripts/install.py → behavior + payload + output + capability guardrails
4. VERIFY — scripts/perf.py --compare-baseline or re-run audit

Six layers

L	Layer	Fix tool
L0	Fixed tax	audit, compress, MCP edit
L1	Turn multiplier	install lever 1
L2	Context inflation	install lever 2 + shrink.py (+ vault restore)
L3	Output waste	install lever 3
L4	Session bloat	new chat / Ask mode — see context-design
L5	Model mismatch	user picks tier — see context-design

Agent execution rules (when this skill is active)

• Run audit before proposing new always-on rules
• Present top 3 ROI fixes with layer tags
• One lever at a time unless user asks batch
• Never let efficiency block correct task completion — see capability-guardrails.md
• Use shrink.py with --vault for tool output > ~4K est. tokens; restore if detail missing
• Honor user overrides: 详细解释 / explore freely / run tests / 看完整日志
• Never claim exact dollar savings without user's pricing data
