Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

Layered Project Memory

This skill creates and maintains structured markdown memory files at project start, then reuses them during planning and execution.

Runtime Rules

  1. Confirm the project root. If unclear, ask the user.
  2. If .plan-memory/ does not exist, run bootstrap script.
python3 scripts/bootstrap_plan_memory.py --root . --project-name ""
  1. Read core memory files:
  • .plan-memory/README.md
  • .plan-memory/product/requirements.md
  • .plan-memory/backend/requirements.md
  • .plan-memory/frontend/requirements.md
  • .plan-memory/shared/constraints.md
  1. Store new information in the most relevant layer file, not in a single aggregate file.
  2. Before final plan output, update .plan-memory/README.md summary index.

Use Cases

  • New project intake with requirements capture
  • Splitting work by backend/frontend scope
  • Long-running refactor/integration work requiring persistent context

Key Rules

  • Existing files are preserved by default; do not overwrite unless --force is passed.
  • For edits, ask for user confirmation before deleting/replacing existing docs.
  • For new projects, fill execution/current-plan.md and product/acceptance-criteria.md first.

Maintenance Rules

  • Keep backend and frontend assumptions separate.
  • Put cross-cutting rules (security/performance/compliance) in shared/constraints.md.
  • Keep the summary index in README.md in sync with added layers/files.
  • End each planning pass by writing plan/risk/acceptance updates into execution/current-plan.md.

스크립트 위치

  • /Users/kdb/.codex/skills/plan-memory-hierarchy/scripts/bootstrap_plan_memory.py

Failure Handling

  • Stop and ask for confirmation if root is unclear.
  • On filesystem errors, report exact failed path and error message.
