[feedback] cheap-capability-scarcity: The model hand-types around verbs that exist in its own tree: a lessons-injection verb unused eight times, a h

Context. Solo-operator project using Claude Code (desktop app, Windows 11) with a lead session on Claude Fable 5.1 orchestrating Opus 5.5 / Sonnet subagents (worktree-isolated), a JSON task store, PreToolUse/SubagentStop hooks and a harvest-train commit flow. This finding was measured on or before 2026-09-22 and filed on 2026-09-28 at the operator's request; numbers are from tool output. No secrets, identities or private paths.

Finding. The model hand-types around verbs that exist in its own tree: a lessons-injection verb unused eight times, a harvest verb's input shape assumed, a queue of prepared prompts bypassed.

Evidence (measured). Ledger LESSONS RECORD class H (unread verbs); memory feedback-cheap-capability-scarcity-prior; the inject verb needed --now and refused until its help was read.

Minimal reproduction. Seed a repo with a verb whose name matches the task noun; measure whether the model reads --help before writing shell.

Ask. Raise the prior that a capability exists; read a verb's help before any multi-line shell around its noun.
