What it does
Agent Action Handshake is an agent skill from friday-platform/friday-studio. Canonical reference for the contract between an FSM action and the agent it invokes. Loads when authoring or debugging any combination of: type: llm inline action, type: agent action with outputTo, type: agent action with inputFrom, agent prompts that need to coordinate with the action invoking them. Covers what the runtime auto-injects per invocation kind (platform tools, complete when outputTo is set), outputTo semantics, inputFrom resolution, the four invocation kinds.
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development. The repository describes itself as: Agent Harness Platform — shareable workspaces, MCP tools, skills, memory, and cron/webhook automations. Self-hosted and transparent.
When your agent uses it
- Development work in your project
Example prompts
- “/agent-action-handshake”
What it can do on your machine
Read from SKILL.md and the folder at commit fb3069a. 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
No scripts in the folder and no shell commands in SKILL.md (its code samples are yaml).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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.
Context cost
Agent Action Handshake loads about 1.5k tokens when it runs. Until then it costs about 129 tokens; SKILL.md has 588 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 588 words (~1,500 tokens).
“This is the contract between an FSM action and the agent it invokes. Most "platform bug" misdiagnoses live in the gap between "how the FSM authors the action" and "what the agent prompt expects." Read this once, then ground every…”
