propose-change

name	propose-change
description	File a proposed change against an existing livespec specification, landing it under <spec-root>/proposed_changes/<topic>.md. Invoked by livespec:propose-change, "propose a change to the spec", or when the user wants to record a spec amendment that the next livespec:revise pass will accept or reject.

propose-change — Codex Driver binding

This file is the thin Codex binding for the propose-change operation, shipped by the livespec-driver-codex Driver plugin (plugin name livespec, so the surface stays livespec:*). The complete harness-neutral driving prose is livespec CORE's artifact at <core-root>/prose/propose-change.md. FIRST resolve <core-root> (next section), THEN read that prose file in full, then execute it end-to-end, binding its harness-neutral vocabulary to this runtime as follows.

Resolving livespec core (<core-root>)

This Driver plugin ships ONLY bindings. The harness-neutral prose and the reference spec-side CLIs ship with livespec core — the livespec plugin from the thewoolleyman/livespec marketplace, which must be installed alongside this Driver. The plugin-root placeholder of THIS plugin resolves to the Driver's own root, which carries no prose/ and no scripts/ — NEVER use it for core paths. Resolve <core-root> once, in this order:

1. If the LIVESPEC_CORE_PLUGIN_ROOT environment variable is set and non-empty, use its value (explicit override; covers nonstandard dev setups, e.g. driving a sibling checkout's core).
2. If <project-root>/.claude-plugin/prose/propose-change.md exists — the governed project IS the livespec core repo itself (--plugin-dir . dev mode / dogfooding) — use <project-root>/.claude-plugin.
3. Otherwise resolve the installed livespec@livespec plugin's source.path from codex plugin list --json -m livespec.

Canonical Bash form (<project-root> defaults to the cwd):

LIVESPEC_CORE_ROOT="$LIVESPEC_CORE_PLUGIN_ROOT"
if [ -z "$LIVESPEC_CORE_ROOT" ] && [ -d "./.claude-plugin/prose" ]; then
  LIVESPEC_CORE_ROOT="$(pwd)/.claude-plugin"
fi
if [ -z "$LIVESPEC_CORE_ROOT" ]; then
  LIVESPEC_CORE_ROOT="$(codex plugin list --json -m livespec 2>/dev/null | python3 -c 'import json, sys
try:
    data = json.load(sys.stdin)
except Exception:
    sys.exit(0)
for plugin in data.get("installed", []):
    if plugin.get("pluginId") == "livespec@livespec":
        sys.stdout.write(plugin.get("source", {}).get("path", ""))
        break' 2>/dev/null || true)"
fi
if [ -z "$LIVESPEC_CORE_ROOT" ] || [ ! -d "$LIVESPEC_CORE_ROOT/prose" ]; then
  echo "livespec core not found. Install it first:" >&2
  echo "  codex plugin marketplace add thewoolleyman/livespec" >&2
  echo "  codex plugin add livespec@livespec" >&2
  exit 1
fi
echo "$LIVESPEC_CORE_ROOT"

If resolution fails, STOP and surface those install instructions to the user instead of improvising paths.

Config-named CLI dispatch

Per livespec core's contract (its contracts.md), every spec-side operation is named in the governed project's .livespec.jsonc under spec_clis.propose_change as an argv-form array, pre-populated with core's reference default and individually overridable. To "run the propose-change CLI named in config":

1. Read <project-root>/.livespec.jsonc (JSONC — tolerate // comments). If the file, the spec_clis section, or the spec_clis.propose_change key is absent, use core's reference default argv: python3 <core-root>/scripts/bin/propose_change.py.
2. If the configured argv contains the literal plugin-root substitution token (the CLAUDE_PLUGIN_ROOT placeholder, written as a $-brace expansion in config), expand it to <core-root> — core's schema defines that token as "the installed livespec plugin root", which is CORE's root, never this Driver's.
3. Append the operation's flags and invoke via the shell tool.

With the default config this collapses to:

python3 "$LIVESPEC_CORE_ROOT/scripts/bin/propose_change.py" <topic> --findings-json <path> [--author <id>] [--reserve-suffix <text>] [--spec-target <path>] [--project-root <path>]

Runtime bindings

• "run the propose-change CLI named in config" / "invoke the propose-change CLI" — dispatch per the Config-named CLI dispatch section above; with the default config:

  python3 "$LIVESPEC_CORE_ROOT/scripts/bin/propose_change.py" <topic> --findings-json <path> [--author <id>] [--reserve-suffix <text>] [--spec-target <path>] [--project-root <path>]
  

• "run the template-resolution CLI" — via the shell tool:

  python3 "$LIVESPEC_CORE_ROOT/scripts/bin/resolve_template.py"
  

• "ask the user" / "confirm with the user" / "surface" / "narrate" — conversational narration in this session.

• "read <file>" — reading the file directly. "write <file>" — writing the file directly.

• "the revise / critique / seed operation" — the revise, critique, seed skills in this Driver plugin (invoke them by name).

• "the doctor prose (prose/doctor.md)" — read $LIVESPEC_CORE_ROOT/prose/doctor.md and follow it (the LLM-driven post-step phase runs under this Driver plugin's doctor binding).

• "core's livespec/schemas/ package" — resolves at runtime to $LIVESPEC_CORE_ROOT/scripts/livespec/schemas/.
