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 | $0.00064 | $0.00514 |
| Opus 5 | $0.00032 | $0.00257 |
| Sonnet 5 | $0.00013 | $0.00103 |
| Haiku 4.5 | $0.00006 | $0.00051 |
Grade A, and why
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 yesterday.
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 — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Handoff
Capture operational state, not a transcript. The next agent needs facts, paths, decisions, and next actions.
When To Use
Use for:
- long-running audits;
- multi-repo publication work;
- paused implementation;
- debugging sessions with active hypotheses;
- research with source ledgers;
- job/client-search workflows;
- context compaction or thread transfer.
Handoff Contents
Include:
- objective and current status;
- repos, branches, important paths, URLs, and local servers;
- decisions made and why;
- files changed, commits, PRs, or releases;
- commands already run and their result;
- active hypotheses, blockers, or pending checks;
- suggested skills for the next session;
- exact next steps in priority order.
Closeout Receipt
When the handoff follows completed project work, include:
changed: files, commits, PRs, or artifacts that matter
verified: checks and results, or why verification was unavailable
skipped_with_reason: docs, memory, cleanup, or rules intentionally not updated
follow_up: bounded next actions only
Link to existing evidence instead of repeating it. Separate local checks from push, CI, deployment, and public availability. Do not turn closeout into cleanup authority: retain temporary files and old plans unless removal was approved. Memory changes require an explicit user request; a handoff is not that request.
Compression Rules
- Link to artifacts instead of copying them.
- Do not duplicate full diffs, logs, PRDs, plans, or source docs.
- Preserve concrete dates and versions when relevant.
- Redact secrets, credentials, private contacts, and unnecessary personal data.
- Separate confirmed facts from assumptions.
Output Location
If creating a file, write it outside the project unless the user asks for an in-repo artifact. Use the OS temp directory or a clear handoff/ location approved by the repo conventions.
Final Response
Tell the user where the handoff lives, what it covers, and what the next agent should do first.
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

handoff is a skill published in the GitHub repository markoblogo/abvx-agent-skills (16 stars, last pushed today), licensed MIT. It adds 64 tokens to every session and 514 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 2026-08-30.
Other skills, from other repositories
potpie-debug-memory
Use while debugging or troubleshooting failures, flaky tests, incidents, production alerts, CI failures, local dev setup issues, repeated bugs, prior fixes, failed attempts, and verification history.
debug-memory
Query and manage the executable feedback debug memory.
memorywhale
Query and write durable debugging memory recorded by MemoryWhale. Use when debugging a failure that may have happened before, when you need the exact error/flags/output from an earlier attempt, when the user asks "how did we fix this last time?", or once you've figured out why something failed / how a fix worked and…
remem
Use when the user asks Codex to recall prior project context, save durable decisions or bug fixes, inspect remem memory health, or activate remem automatic memory hooks from the Codex plugin.
role-skill-boundary-audit
Audit where governance instructions belong (Role.md, skill, global policy, workflow docs, memory, or an agent-boundary change); enforce minimal verbosity in roles and skills. Diagnostic by default.
