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

shipkit-work-memory 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 1mo 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.

shipkit-work-memory - Session Progress & Resume State

Purpose: Capture structured session progress — milestones, blockers, decisions, and resume state — by inferring from conversation and git. User confirms, Claude does the work.

Note: Claude Code's auto-memory (v2.1.59+) automatically saves basic session context. This skill is for structured progress tracking that auto-memory doesn't capture: explicit milestones, decision rationale, blocker status, and handoff state for session continuity.

Output: .shipkit/progress.json — A timeline graph artifact ideal for session history visualization.


When to Invoke

User triggers:

  • "End session"
  • "Log progress"
  • "Save checkpoint"
  • "What did we do?"
  • "Save session"

Suggested after:

  • Long implementation sessions
  • Before context gets full
  • Before switching tasks
  • End of work session

Prerequisites

None required - Can start fresh.

Uses if available:

  • .shipkit/progress.json - Merge with existing sessions
  • Git - For modified files detection

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.
