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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00022 | $0.01302 |
| Opus 5 | $0.00011 | $0.00651 |
| Sonnet 5 | $0.00004 | $0.00260 |
| Haiku 4.5 | $0.00002 | $0.00130 |
Grade A, and why
economy-mode 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 8d 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.
This is a copy
100% identical to economy-mode — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SCOPE
✅ THIS SKILL PRODUCES:
- A modified Layer 3 model selection table applied when economy mode is active
economyMode: truewritten to.squad/config.jsonwhen activated persistently- Spawn acknowledgments with
💰indicator when economy mode is active
❌ THIS SKILL DOES NOT PRODUCE:
- Code, tests, or documentation
- Cost reports or billing artifacts
- Changes to Layer 0, Layer 1, or Layer 2 resolution (user intent always wins)
Context
Economy mode shifts Layer 3 (Task-Aware Auto-Selection) to lower-cost alternatives. It does NOT override persistent config (defaultModel, agentModelOverrides) or per-agent charter preferences — those represent explicit user intent and always take priority.
Use this skill when the user wants to reduce costs across an entire session or permanently, without manually specifying models for each agent.
Activation Methods
| Method | How |
|---|---|
| Session phrase | "use economy mode", "save costs", "go cheap", "reduce costs" |
| Persistent config | "economyMode": true in .squad/config.json |
| CLI flag | squad --economy |
Deactivation: "turn off economy mode", "disable economy mode", or remove economyMode from config.json.
Economy Model Selection Table
When economy mode is active, Layer 3 auto-selection uses this table instead of the normal defaults:
| Task Output | Normal Mode | Economy Mode |
|---|---|---|
| Writing code (implementation, refactoring, bug fixes) | claude-sonnet-4.5 |
gpt-4.1 or gpt-5-mini |
| Writing prompts or agent designs | claude-sonnet-4.5 |
gpt-4.1 or gpt-5-mini |
| Docs, planning, triage, changelogs, mechanical ops | claude-haiku-4.5 |
gpt-4.1 or gpt-5-mini |
| Architecture, code review, security audits | claude-opus-4.5 |
claude-sonnet-4.5 |
| Scribe / logger / mechanical file ops | claude-haiku-4.5 |
gpt-4.1 |
Prefer gpt-4.1 over gpt-5-mini when the task involves structured output or agentic tool use. Prefer gpt-5-mini for pure text generation tasks where latency matters.
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.

economy-mode is a skill published in the GitHub repository alonf/specrew (54 stars, last pushed yesterday), licensed MIT. It adds 22 tokens to every session and 1,302 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to economy-mode, differing in 0 lines, and is treated as a copy.
