handoff

A command for saving or loading a structured handoff document between coding sessions.

In plain words
What is it for?
Use it to create a handoff after working and resume from the latest handoff when returning to the project.
Why use it?
It prevents important decisions, changed files, unfinished work, blockers, and next steps from being lost when a session ends.

Install

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.

git clone --depth 1 https://github.com/FerroxLabs/ijfw

Or install claude, the plugin that ships this one along with the rest of its 18 commands, 37 agents, 1 MCP server.

Per session 21 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 126 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

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 3d 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

/handoff create -- Generate a structured handoff document for session continuity. Capture: what was accomplished, what's in progress, key decisions made, modified files, next steps, blockers, open questions. Save to .ijfw/memory/handoff.md

/handoff resume -- Load the most recent handoff and display a summary. Automatically invoked at SessionStart if a handoff exists.

/handoff (no args) -- Show current handoff status.

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.

handoff is a command published in the GitHub repository FerroxLabs/ijfw (210 stars, last pushed 9d ago), licensed MIT. It adds 21 tokens to every session and 126 once invoked, about $0.0001 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.
