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

archive 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 4d 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.

Origin

This is a copy

98% identical to plan-archive — 10 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

You are archiving the user's completed (or abandoned) plan for future reference.

To do this, follow these steps precisely:

  1. Read .claude/plan-critique-config.json and get plansFolder path from settings. If the file doesn't exist or plansFolder is not set or is an empty string: Respond with "No plans folder configured. Run /plan:create first to set up."
  2. Get the Claude Code process ID by running: echo $PPID. Store this as sessionPID.
  3. Clean up stale sessions: Scan [plansFolder]/.sessions/ for files. For each file named with a PID, check if that process is still running via kill -0 [PID] 2>/dev/null. If the command fails (process not running), delete that session file. This is non-blocking cleanup.
  4. Read the current session's plan from [plansFolder]/.sessions/[sessionPID] if it exists. Store as sessionPlan.
  5. Scan [plansFolder]/ for subdirectories (each subdirectory is a plan). Exclude archived/ and .sessions/ folders and any files, only list plan directories. If no plan folders exist: Respond with "No plans found. Nothing to archive."
  6. Select the plan to archive:
    • If sessionPlan exists and matches a plan folder, auto-select it. Inform the user: "Using current session plan: [sessionPlan]"
    • Else if only one plan exists, auto-select it and inform user.
    • Otherwise, ask the user to select a plan from the list. Example:
      Available plans:
      1. add-user-authentication
      2. refactor-database-layer
      3. implement-caching
      
      Which plan would you like to archive? [1-3]
      
  7. Check prerequisites. If [plansFolder]/[selected-plan]/plan.md does not exist or is empty: Respond with "Nothing to archive. Plan file is missing or empty."
  8. Ensure [plansFolder]/archived/ exists, create it if not.
  9. Extract metadata:
    • Read plan.md to get the plan title (first H1 heading). If no title, use folder name.
    • Read critique.md to get keywords (if available)
    • Read execution-log.md to get execution status (if available)
  10. Generate archive folder name using format: YYYY-MM-DD_HH-MM-SS_[slug]/ Example: 2026-01-12_14-30-00_add-user-authentication/
  11. Create the archive folder at [plansFolder]/archived/[folder-name]/
  12. Copy contents from [plansFolder]/[selected-plan]/ to the archive:
    • Include: plan.md, execution-log.md (if exists), all other files (SQL, images, etc.)
    • Exclude: critique.md, execution-state.json
  13. Create archive-info.md in the archive folder using the format in archive-info-format.md.
  14. Delete the original plan folder [plansFolder]/[selected-plan]/ entirely.
  15. Clean up session references to the archived plan:
    • Delete [plansFolder]/.sessions/[sessionPID] if it contains the archived plan slug.
    • Scan all other session files and delete any that reference the archived plan (handles stale references).
  16. Respond with confirmation:
    Plan archived to: [plansFolder]/archived/[folder-name]/
    
    The original plan folder has been removed.
    Create a new plan with `/plan:create`.
    

Notes:

  • Never include critique.md in the archive (only keywords are preserved in archive-info.md)
  • Always include the full original plan and all supporting files
  • Include execution log only if the plan was executed
  • Use current timestamp for the archive folder name
  • Preserve the original file structure within the archived folder
  • Always delete the original plan folder after archiving
  • It is valid to archive a plan that was never executed (abandoned, reference, or superseded plans). In this case, the execution status will be NOT_EXECUTED.

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.
