handoff-mcp AGENTS.md

A set of repository instructions for handoff-mcp, a tool that preserves work context between coding sessions. It defines how to manage tasks, session notes, tests, and safe repository changes.

In plain words
What is it for?
Use it when working on handoff-mcp to load and save session context, track task progress, verify completion criteria, and follow the project’s Rust workflow.
Why use it?
It reduces lost context when work moves between sessions or agents. It also clarifies which files and operations need special handling.

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.

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-mcp AGENTS.md 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 — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.

handoff-mcp repository guidance

Scope and safety

  • Work in the current repository and preserve unrelated user changes.
  • Do not push, publish, deploy, or commit directly to main or master.
  • Do not edit .handoff/ files directly. Use the Handoff MCP tools for task, session, document, and memory state.
  • Treat write, network, credential, migration, and destructive operations as requiring the applicable Codex approval or explicit user authorization.

Session handoff

This repository uses Handoff MCP for session continuity.

  • At session start, call handoff_load_context. If it returns session_guidance, establish an active session with handoff_save_context(session_status: "active") before work begins.
  • Track implementation work with handoff_update_task; check each verified done criterion with handoff_check_criterion before moving a task to done.
  • At session end, save a concise summary, decisions, blockers, context pointers, related task IDs, and concrete next-step suggestions.

Repository workflow

  • Rust commands must source scripts/cargo-env.sh first. Use it for builds, tests, formatting, clippy, audit, and cargo-deny checks.

  • Run focused checks for the files changed, then the relevant release checks:

    . scripts/cargo-env.sh && cargo fmt --all -- --check
. scripts/cargo-env.sh && cargo clippy --all-targets -- -D warnings
. scripts/cargo-env.sh && cargo test
npm run test:js
./scripts/sync-workflow-inline.sh --check
./scripts/sync-plugin-skills.sh --check
./scripts/sync-plugin-version.sh --check

  • When the Codex CLI is installed, also run npm run test:codex-plugin. It installs the plugin into an empty local Codex profile and verifies the installed package contents.

  • When changing the package version, keep package.json, Cargo.toml, the Claude plugin manifests, and plugins/handoff-task-loop-codex/.codex-plugin/plugin.json in sync. The existing version-sync script covers the Claude manifests; update the Codex manifest deliberately and verify it too.

  • When changing shared skills under skills/, run ./scripts/sync-plugin-skills.sh so the marketplace-served plugin/skills/ copy remains synchronized.

  • Validate a Codex plugin and each changed Codex skill before release. Install it from the repository marketplace and verify the installed cache rather than only validating source files.

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.
