// docs-guard-exempt: 'docs/readme.md' is a fast-check filler token and 'commit_docs' is a config key name, not a docs/ path read.
/**
 * commit_docs bypass guard (#1783; superseded/widened by #3585)
 *
 * #1783: when users set commit_docs: false during /gsd-new-project,
 * .planning/ files should never be staged or committed. The gsd-tools.cjs
 * commit wrapper already checks this flag, but three locations in
 * execute-phase.md and quick.md used raw `git add .planning/` commands that
 * bypassed it.
 *
 * The original guard here was a two-file allowlist (execute-phase.md,
 * quick.md) whose regex required the literal substring `.planning/` on the
 * SAME line as `git add`. That is structurally blind to `git add -A` /
 * `git add .` / `git add -u` — none of those lines mention `.planning/` at
 * all, yet every one of them stages the whole index, including
 * `.planning/`, regardless of the config. #3585 replaces it with a
 * repo-wide scan that classifies `git add` invocations by what they can
 * actually reach (the blanket/wildcard forms, `.planning`-qualified paths in
 * either separator convention, and any argument carrying an unresolved
 * shell variable, fail-closed), across every scan root that carries live
 * workflow/agent/command/skill/reference content — not just the original
 * two files.

 * Regression for #3678 — gsd-executor force-commits .planning/ files when

 * Root cause: the executor agent prompt (agents/gsd-executor.md) tells the

 * in the per-plan final_commit block, but the prompt says nothing about
 * what to do when the SDK returns `{committed: false, skipped: true,

 * agent improvises raw `git add` / `git commit` against `.planning/` paths
 * (and uses `-f` to bypass gitignore), which is exactly the leakage the
 * reporter observed.
 *
 * Fix surface:
 *   1. Agent prompt: explicit handling text in the final_commit section.
 *   2. SDK envelope: add `skipped: true` field so agents see "skipped" as a
 *      first-class success signal, not "committed is missing, must improvise."
 *   3. Structural guard: ban `git add -f` / `git add --force` from agent and
