delegation-tiering skillA

delegation-tiering is agent-read markdown (skill) from jakeselby/agent-harness: 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..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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 `harness tiers check` reads the catalog Codex
…

How to install

Latest version
mdr add jakeselby/agent-harness/delegation-tiering@git:20260923.c9e2ec3
Exact content
mdr add jakeselby/agent-harness/delegation-tiering@sha256:c77a9f887189f26f

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
