# planning-with-files: resolve the active plan, verify its attestation, and emit
|
|
# plan context for injection into the model turn.
|
|
#
|
|
# This script holds the logic that used to live inline in the UserPromptSubmit,
|
|
# PreToolUse, and PreCompact hook command scalars (v2.43 and earlier). The hooks
|
|
# now dispatch to this file via the proven self-discovery pattern, so the logic
|
|
# is versioned and testable instead of duplicated across 14 SKILL.md variants.
|
|
#
|
|
# Context modes (--context=...):
|
|
# userprompt (default) — full plan head + progress/ledger summary. Once per turn.
|
|
# pretool — short plan head only (head -30), no progress.
|
|
# precompact — compaction reminder only (no plan body), matches v2.
|
|
#
|
|
# v3 behavior keys off explicit opt-in. With no .mode file present the output is
|
|
# byte-equivalent to the v2.43 hook scalars (legacy invariant). Autonomous and
|
|
# gated modes change the injection shape (full fidelity + structured ledger
|
|
# summary instead of raw progress.md tail; per-tool-call injection dropped).
|
|
#
|
|
# Multi-root disambiguation (issue #212): PWF_PLAN_ROOT pins the effective plan
|
|
# root for threads whose cwd is a shared parent of the real project; a
|
|
# .planning/sessions dir arms the same session-attachment guard the Codex
|
|
# adapter enforces; and an ambiguous cwd-guessed resolution refuses to inject
|
|
# when a direct child of the root carries its own competing .planning.

# nothing notices (injection, plan-doctor and the Stop gate all read the
