resume

A command that restores context from a previous coding session by reading its checkpoint and project notes. It also checks the current branch and uncommitted changes before continuing.

In plain words
What is it for?
Use it to reload a saved task, review its lessons and domain documents, and prepare to continue the next recorded step.
Why use it?
It helps prevent work from restarting without knowing what was completed, what changed, or what should happen next.

Made for: Claude Code.

Per session 20 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 355 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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.

What it actually says

Resume previous session: $ARGUMENTS

Pre-loaded context

Branch: !git branch --show-current Uncommitted: !git status --short 2>/dev/null | head -20 Current todo: !head -40 claude/tasks/todo.md 2>/dev/null || echo "No active todo"

Instructions

  1. Read checkpoint — Read claude/tasks/todo.md in full. Identify the most recent task.
  2. Read lessons — Read claude/tasks/lessons.md (mandatory).
  3. Verify branch — Compare against checkpoint. Warn if different.
  4. Check uncommitted state — Compare against checkpoint.
  5. Reload domain docs — Read each claude/*.md listed in checkpoint's "Loaded docs".
  6. Present resumption summary:
    ## Session Resumed
    
    **Task:** [title]
    **Branch:** [current] (matches checkpoint: ✅/❌)
    **Last completed step:** [step N]
    **Next action:** [description from NEXT → marker]
    **Domain docs loaded:** [list]
    
    Ready to continue. Shall I proceed with [next action]?
    
  7. Wait for user confirmation before proceeding.

If no checkpoint exists

  1. Read claude/tasks/lessons.md
  2. Read claude/architecture.md
  3. Ask the user what task to work on
Changes

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.
