craft-session-solidify

A session-checkpoint helper that records the current project state, pending work, decisions, and optional handover notes in project files, then commits those changes.

In plain words
What is it for?
Use it to save a mid-session checkpoint, document unfinished tasks and decisions, prepare a handover, or respond to a context-usage warning.
Why use it?
It preserves progress during a long or interrupted coding session so work can continue with the right context.

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

craft-session-solidify 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.

How it starts

The opening of the file, as written. The whole thing — 192 lines — stays where its author put it; the contents beside it link to each section on GitHub.

craft-session-solidify

Save the current state — then keep working.

When to run

  • Automatic: when the context monitor reports ~75% utilization
  • Manual: when the user types /craft-session-solidify
  • Proactive: when you notice a lot has happened that is not yet documented and the context window is filling up

Scope — what does NOT belong here

This skill maintains project documentation in .craft/. It does not maintain Claude's own memory. The boundary:

Tool Purpose Target
/craft-session-solidify Project state, backlog, decisions, handover .craft/*.md
/remember Save a single fact, decision, or warning .claude/memory/YYYYMMDD_*.md
/learn Abstract a pattern from context into a transferable insight .claude/memory/YYYYMMDD_*.md

Concretely: do not write new .claude/memory/ entries from this skill. If you notice during the solidify that a fact or pattern is worth keeping — mention it in the closing report as a recommendation (worth a /remember or worth a /learn), but do not write it yourself.

.craft/DECISIONS.md (project-level ADR log) and .claude/memory/ entries with type=decision (Claude's personal memory) are deliberately different layers. Some duplication is fine, but it is not the goal of this skill.

Steps

1. Get an overview

git diff --stat HEAD 2>/dev/null
git status --short 2>/dev/null
git log --oneline -5 2>/dev/null
ls .craft/ 2>/dev/null || echo "no .craft/"

If there is no .craft/: run anyway, but skip the doc-writing steps. Commit and short report still happen. At the end, suggest running /craft-project-setup.

2. Update .craft/PROJECT_STATE.md

Prepend a section at the top (newest state first):

## State: [YYYY-MM-DD HH:MM]

### Working
- ...

### In progress
- ...

### Known issues
- ...

### Technical debt
- ...

Be honest. If something is not working, say so explicitly — do not omit.

3. Update .craft/BACKLOG.md

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.

craft-session-solidify is a skill published in the GitHub repository derjochenmeyer/claude-code-craft (2 stars, last pushed 4mo ago), licensed MIT. It adds 64 tokens to every session and 1,615 once invoked, about $0.0003 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 2026-08-31.
