Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00050 | $0.00384 |
| Opus 5.5 | $0.00020 | $0.00154 |
| Sonnet 5.5 | $0.00010 | $0.00077 |
| Haiku 4.5 | $0.00005 | $0.00038 |
Grade A, and why
checkpoint scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Capture the current session as a resumable handover so a fresh session (after /clear) can pick up cold without undoing work.
Steps
-
Run
printf '%s-%s' "$(date +%Y-%m-%dT%H%M)" "$(openssl rand -hex 3)"to get a timestamp with a random suffix (e.g.2026-04-22T1717-a3f9c1) for the filename. -
Generate a summary covering these sections — keep the whole document under 400 words:
- Project: name, repo path, one-line description
- Accomplished: bullet list of what was done this session
- Current state: branch, uncommitted changes, open PRs, test status, anything a fresh session needs to know to not undo work
- Pending: numbered list of next actions with enough detail to resume cold (include specific commands, file paths, URLs where relevant)
- Environment: non-obvious setup that won't survive a shell restart (e.g. ssh-add, nvm, auth tokens, background processes)
-
Write the summary to
~/.claude/handovers/<timestamp>.md. -
Print exactly this (substituting the real timestamp):
Saved to ~/.claude/handovers/<timestamp>.md
After /clear, paste this to resume:
Read ~/.claude/handovers/<timestamp>.md and resume from where we left off
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.

checkpoint is a skill published in the GitHub repository toBzh30/Claude-Project-Bootstrap (3 stars, last pushed 2mo ago), licensed MIT. It adds 50 tokens to every session and 384 once invoked, about $0.0002 per session on Opus 5.5. 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.

thought
Capture a surprising model answer as a thought entry. Synthesizes the last answer with context, saves as a granular file, and auto-updates the TLDR.
handoff
Write a short handoff note for the next chat or a teammate, with what is done, what is open, what comes next and what was rejected and why. Saves it to project memory so the next chat sees it at the start, and prints it so it can be pasted into a message or a pull request. Use when the user ends a piece of work…
recall
Must be used at the start of any non-trivial task involving code changes, debugging, repo exploration, file inspection, or environment/tooling investigation to surface stored guidance before analysis or tool use.
alive:session-history
Revive sessions (quick or heavy), browse, and search — 'what happened recently?', 'find the session where we discussed X', 'revive yesterday's session'. For single-session recall and multi-session browsing. If the human needs to merge multiple sessions into one working context or detect conflicts between parallel…
knowledge-priming-refiner
Facilitate a structured conversation to create a project-specific knowledge base document. Produces a knowledge-base.md that primes AI with the project's tech stack, architecture, trusted sources, and project structure. Use when the user says 'set up knowledge base', 'prime the project', 'onboard AI', 'create…
