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 | $0.00078 | $0.00249 |
| Opus 5 | $0.00039 | $0.00125 |
| Sonnet 5 | $0.00016 | $0.00050 |
| Haiku 4.5 | $0.00008 | $0.00025 |
Grade A, and why
stack-handoff 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
stack-handoff
Persist and resume working state across sessions.
Write a handoff
npx @drmahdikazempour/agent-stack handoff write captures into .agent-stack/handoff.md:
- current git branch, uncommitted changes, recent commits,
- a template for the current task, decisions made, and next steps.
Edit the generated file to fill in the narrative parts before you stop.
Resume
npx @drmahdikazempour/agent-stack handoff resume prints the latest handoff so you can continue exactly where the last session stopped.
When to use
- At the end of any working session.
- Before switching branches or context.
- At the start of any resumed or handed-off task — resume first, then continue.
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.

stack-handoff is a skill published in the GitHub repository drmahdikazempour/agent-stack (2 stars, last pushed 3mo ago), licensed MIT. It adds 78 tokens to every session and 249 once invoked, about $0.0004 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.
