What it does
Coordinate Handoffs is an agent skill from digipulse-engineering/GAAI-framework. Validate sub-agent handoff artefacts, sequence phase transitions, and manage retry and escalation logic. Activate after each sub-agent terminates to determine next action.
Its SKILL.md is about 2.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Works with any filesystem-based AI coding agent
It sits in Agent Workflows, covering Subagents. The repository describes itself as: Turns AI coding tools into reliable software delivery systems. Drop a .gaai/ folder into any project — Discovery defines what to build, Delivery executes autonomously until…
When your agent uses it
- Tasks that involve Subagents
Example prompts
- “/coordinate-handoffs”
Requirements
- Node.js
- Compatibility (from SKILL.md): Works with any filesystem-based AI coding agent
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Check: does {id}.execution-plan.md exist?
- Check: does the execution plan contain required sections? (Implementation Sequence, Edge Cases, Test Checkpoints, Risk Register)
- Valid artefact: → PROCEED to Implementation phase
What it can do on your machine
Read from SKILL.md and the folder at commit a26ea7a. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
gitnpx
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git and npx, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Compatibility
Works with any filesystem-based AI coding agent
From compatibility in the SKILL.md frontmatter.
Context cost
Coordinate Handoffs loads about 2.5k tokens when it runs. Until then it costs about 48 tokens; SKILL.md has 1,134 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,134 words (~2,526 tokens).
“Activate after each sub-agent writes its handoff artefact and terminates.”
