cost-tier-routing SKILL.md skillA

cost-tier-routing from the-artificer-of-ciphers-llc/skills-from-the-artificer is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add the-artificer-of-ciphers-llc/skills-from-the-artificer/cost-tier-routing@git:20261014.fb8dd14

Pins git:20261014.fb8dd14 in mdr.lock. Pin the fingerprint instead.

Use BEFORE doing direct file search, bulk reads, data import/export, or routine coding edits in the main conversation. Routes work to the cheapest model that can do it correctly — haiku for search/IO, sonnet for coding, opus for orchestration/architecture. Triggers when about to call Read on >2 files, Grep/Glob across the repo, batch CSV/JSON transforms, or any "where is X / list all Y / count Z" question. Also triggers when the orchestrator (you, on opus) is about to write straightforward…

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

# Cost-Tier Routing

Opus tokens cost ~5x sonnet and ~25x haiku. Doing `Read` and `Grep` on opus is lighting money on fire. This skill is the discipline for routing every action to the cheapest model that can do it correctly.

> **This skill requires three companion agents** — `haiku-scout`, `haiku-importer`, and `sonnet-coder` — installed in `~/.claude/agents/`. See this package's `README.md` for the two-step install. The skill is inert without the agents because the `model:` pin lives in the agent files, not here.

## The rule

Before any of these actions in the main (opus) context, **dispatch to a subagent instead**:

| Action | Route to | Why |
|---|---|---|
| `Read` more than 1–2 files in a row | `haiku-scout` | Bulk reads burn opus context |
| `Grep` / `Glob` across the repo | `haiku-scout` | Mechanical lookup |
| "Where is X defined?" / "What references Y?" | `haiku-scout` | Pure search |
| Count LOC, list files, read a config | `haiku-scout` | Trivial IO |
| Convert/parse/split/merge data files | `haiku-importer` | Mechanical transform |
| Download + parse a fixture or seed file | `haiku-importer` | Mechanical IO |

How to install

The exact contents, by fingerprint

mdr add the-artificer-of-ciphers-llc/skills-from-the-artificer/cost-tier-routing@sha256:5a9a60dfe5921691

The line at the top of this page pins the label git:20261014.fb8dd14, 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.
