delegation-tiering SKILL.md skillA
This file is byte-identical to the first copy the registry indexed, one of 4 indexed copies. Same content hash, so the same checks give both the same grade.
delegation-tiering from jakeselby/agent-harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Decide whether to spawn a subagent, and on which model tier and reasoning effort. Use when planning a fan-out, choosing a subagent model, writing a workflow script's opts.model, authoring an agent definition, setting a repo's cost posture, or when a delegation decision is non-obvious.
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
# Delegation and model tiering The operative defaults live in `~/.claude/rules/delegation.md`. This is the reasoning, the evidence, and the cases that file is too short to carry. Research date **2026-09-16**. Where a number is vendor-run or unreplicated it says so. Treat every tier boundary below as extrapolation unless it names a Claude-tier measurement. ## Runtime mapping A shared role names one of four capability classes, strongest first — `frontier`, `strong`, `standard`, `light` — in its contract's `tier:` line, and each adapter's `bindings.json` maps the classes it has qualified to native models in a `tiers` table. The class is a statement about the work; the table is the only place a provider's model names appear. An unmapped class resolves to the nearest *stronger* mapped class and otherwise inherits the session model — never downward, because a weaker model than the role asked for is a silent failure. Both adapters map all four. Claude Code's table uses version-free aliases. Codex has none — every id carries a version and keeps resolving after its successor ships — so `citizen tiers check` reads the catalog Codex …

How to install
mdr add jakeselby/agent-harness/delegation-tiering@sha256:5e6b57ff199e6001The line at the top of this page pins the label git:20261006.b2bd78a, 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.
