project-agent-handoff

project-agent-handoff is a skill for Claude Code, Codex from besoeasy/open-skills. It costs 74 tokens per session (1,305 once invoked), scanned A, original, MIT.

A project-preparation workflow for handing a codebase to another AI coding agent. It examines the project, records its structure and safety rules in AGENTS.md, and runs the test suite to check the handoff.

In plain words
What is it for?
Use it before another agent starts work, when a project has no current AGENTS.md, or after an agent has become confused. It helps document runtime details, important commands, and boundaries for safe changes.
Why use it?
It reduces the risk that a new agent will misunderstand the project, change unsafe parts, or repeatedly ask basic questions. The initial diagnosis is read-only except for writing the guide and running tests.

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

project-agent-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 7d 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.

Project Agent Handoff

Prepares a project for work by another AI coding agent: diagnose the current state read-only, inventory architecture and safety gates, write or refresh AGENTS.md, and verify the test suite. The goal is that any agent dropped into the repo can operate correctly without asking the user basic questions or touching dangerous code.

When to use

  • The user says "help with " or "get up to speed on ".
  • A repo is about to be opened by a different agent and has no (or stale) AGENTS.md.
  • An agent previously failed or got confused working in a repo — use this to hand it a correct map.

Required tools

  • A shell (bash) and the standard file tools of your agent runtime.
  • No external APIs required. All steps are local and read-only except the explicit test run and the AGENTS.md write.

Workflow

1. Diagnose first (read-only)

Run these and record results before proposing any change:

# Running processes / sessions related to the app
ps aux | grep -Ei "python|node|engine|watchdog" | grep -v grep
tmux ls 2>/dev/null            # long-running app sessions
uptime && date -u               # reboot? note timezone vs UTC logs
# Runtime state files (adjust names to the project)
ls -lat data/ 2>/dev/null | head -20
cat data/live_status.json 2>/dev/null   # or equivalent status/state files
tail -30 logs/*.log 2>/dev/null         # recent errors

Key discipline:

  • Logs often use UTC while the shell shows local time. Convert before concluding a service is "stale" (e.g. date -u).
  • Check what stdout a live process points at: ls -l /proc/<pid>/fd/1 — tmux/systemd redirection hides real output.
  • Never conclude a bug from one log line; count occurrences (grep -c "PATTERN" log) and read the surrounding events.

2. Inventory the architecture

  • List entry points: ls *.py *.sh / cat package.json / cat Cargo.toml.
  • Identify anything that moves money, sends messages, or mutates prod: mark these as safety gates that any agent must respect.
  • Identify config: where secrets live (.env, env vars), how modes are switched (paper vs live vs testnet).

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.
