eco-mode SKILL.md skillA

eco-mode from tmusser/ai-engineering-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add tmusser/ai-engineering-skills/eco-mode@git:20261026.2efd117

Pins git:20261026.2efd117 in mdr.lock. Pin the fingerprint instead.

Keep a small, budgeted working context for low-cost model execution without weakening task contracts, required sources, or verification.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Eco Mode

## Purpose

Make bounded agent work economical through source selection, fresh-context
discipline, and a measurable preflight. This is an opt-in working-set policy,
not a second workflow, model switch, or replacement for verification.

## When to use

Use when the operator invokes eco mode, asks to minimize context costs, or runs a
bounded task on a fast inexpensive model. Especially useful for maintenance,
well-scoped coding, extraction, and small-model delegated work.

Do not force it on ambiguous research, incident response, high-stakes decisions,
or tasks whose required evidence cannot fit. Escalate when necessary.

## Inputs

- Objective, current source of truth, scope and acceptance/proof targets
- Only the selected relevant code/docs and durable state files
- Optional provider/model choice outside this skill
- Local selected-content budget, default 60,000 UTF-8 bytes
- Optional, explicitly named required source files and literal proof anchors

## Workflow

1. Resolve the route first, or honor an already explicit route. Do not append
   ceremony to a sufficient workflow.
2. Load only the current authority-bearing task sources, relevant file sections,
…

How to install

The exact contents, by fingerprint
mdr add tmusser/ai-engineering-skills/eco-mode@sha256:d992f86c25ed27b3

The line at the top of this page pins the label git:20261026.2efd117, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
