resume

A command that finds the saved state of an interrupted Plan Cascade task and selects the matching resume process. It supports large project plans, worktree-based tasks, and automatic hybrid tasks.

In plain words
What is it for?
Use it after an interruption to detect saved planning state and resume the appropriate task.
Why use it?
It avoids losing progress or manually figuring out which planning files and task flow should continue.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

resume scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Plan Cascade - Universal Resume

Automatically detect and resume any interrupted Plan Cascade task.

Path Storage Modes

This command works with both new and legacy path storage modes and auto-detects which is active:

New Mode (Default)

Files are stored in user data directory:

  • Windows: %APPDATA%/plan-cascade/<project-id>/
  • Unix/macOS: ~/.plan-cascade/<project-id>/

Detection checks:

  • <user-dir>/mega-plan.json for mega-plan tasks
  • <user-dir>/.worktree/*/ for worktree tasks
  • <user-dir>/prd.json for hybrid-auto tasks

Legacy Mode

Files in project root:

  • <project-root>/mega-plan.json
  • <project-root>/.worktree/*/
  • <project-root>/prd.json

The command scans both locations for maximum compatibility.

Tool Usage Policy (CRITICAL)

To avoid command confirmation prompts:

  1. Use Read tool for file reading - NEVER use cat via Bash
  2. Use Glob tool for finding files - NEVER use ls or find via Bash
  3. Only use Bash for git commands

Step 1: Detect Task Context

Check for various planning files to determine what type of task was interrupted.

1.1: Check for Mega Plan

# Get mega-plan path from PathResolver
MEGA_PLAN_PATH = uv run python -c "from plan_cascade.state.path_resolver import PathResolver; from pathlib import Path; print(PathResolver(Path.cwd()).get_mega_plan_path())"

Use Read tool to check if mega-plan.json exists:
  Read(MEGA_PLAN_PATH)

# Also check legacy location if different
If file not found and MEGA_PLAN_PATH != "mega-plan.json":
  Read("mega-plan.json")

If file exists and is valid JSON:
  CONTEXT = "mega-plan"
  Extract: goal, target_branch, features count

1.2: Check for Hybrid Worktree

Use Read tool to check for worktree config:
  Read(".planning-config.json")

If file exists and mode = "hybrid":
  CONTEXT = "hybrid-worktree"
  Extract: task_name, target_branch

1.3: Check for Worktrees Directory

# Get worktree base directory from PathResolver
WORKTREE_BASE = uv run python -c "from plan_cascade.state.path_resolver import PathResolver; from pathlib import Path; print(PathResolver(Path.cwd()).get_worktree_dir())"

Use Glob tool to find worktrees in new mode location:
  Glob("{WORKTREE_BASE}/*/.planning-config.json")
  Glob("{WORKTREE_BASE}/*/prd.json")

# Also check legacy location if different
If WORKTREE_BASE != ".worktree":
  Glob(".worktree/*/.planning-config.json")
  Glob(".worktree/*/prd.json")

If any worktrees found:
  CONTEXT = "has-worktrees"
  List all found worktrees

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

resume is a command published in the GitHub repository Taoidle/plan-cascade (131 stars, last pushed 5mo ago), licensed MIT. It adds 32 tokens to every session and 2,357 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
