Planar Binding
Bind an external service, API, or agent to a contract with defined scope, duration, and failure modes.
What This Skill Does
Use this spell when you need to summon a powerful external entity - a third-party API, a cloud service, another agent - and lock it into serving your workflow under explicit terms.
In this grimoire, Planar Binding is treated as a hybrid spell with a prototype delivery profile.
Canonical reference input: Planar Binding (spell).
When To Use
- You are integrating an external API or service and need to define the contract before granting access.
- An external agent or model needs to be constrained to a specific role, scope, and duration within your workflow.
- You want explicit failure modes, cost limits, and termination conditions before binding a dependency.
Prerequisites
- No extra runtime dependencies beyond Hermes Agent and the normal toolset for this session.
Procedure
- Restate the target, the success condition, and any no-touch boundaries before taking action.
- Name the external entity to bind and the service it will perform.
- Define the binding contract: scope of access, duration, rate limits, cost ceiling, and failure behavior.
- Establish the termination conditions - when and how the binding ends.
- Execute the binding with the user's explicit consent and credentials, then confirm the contract is active.
- Package the result as the deliverables below, with confidence, assumptions, and unresolved risk called out explicitly.
Deliverables
- A binding contract specifying scope, duration, cost limits, and failure modes.
- A confirmation that the external entity is active and operating within bounds.
- A termination procedure for releasing the binding cleanly.
Pitfalls / Guardrails
- Call out the glue, permissions, or missing infrastructure before you imply this is fully operational.
- Never bind to an external service without the user's explicit consent and credentials.
- Make cost and rate-limit implications explicit before executing any binding.
- Include termination conditions in every binding - no open-ended commitments.
Verification
- Check that the result includes every deliverable promised above.
- Check that confirmed facts, assumptions, and inferences are visibly separated.
- Check which parts are concrete actions versus framing, so the user can tell what is real now.
- Check that any missing glue code, permissions, or future work is labeled before the skill is treated as ready.
