Section 1
Hermes As A Local Agent Brain
Hermes is useful when you need open-weight instruction following, tool-call discipline, and local control more than frontier-model peak reasoning.
- 1Name the job before naming the tool.
- 2Write the smallest useful scope the agent can finish.
- 3Run the result as a user, not as a fan of the tool.
- 4Inspect the diff, data access, and failure path before sharing.
Use this as the working prompt or checklist for the lesson.
Pick one low-risk agent job for Hermes: summarize logs, draft release notes, or classify support tickets. Keep writes disabled at first.- What should the user be able to do when this is finished?
- What data should the app or agent never expose?
- What test proves the change works?
- What rollback path exists if the output is wrong?

Write A Prompt Contract For Hermes
Section 3
Write A Prompt Contract For Hermes
Local models benefit from explicit output contracts: schema, allowed actions, refusal behavior, and retry rules.
- 1Name the job before naming the tool.
- 2Write the smallest useful scope the agent can finish.
- 3Run the result as a user, not as a fan of the tool.
- 4Inspect the diff, data access, and failure path before sharing.
Use this as the working prompt or checklist for the lesson.
System: return only JSON matching this schema. If missing data, return status:'needs_input'. Never invent IDs. Harness: reject invalid JSON and retry once.- What should the user be able to do when this is finished?
- What data should the app or agent never expose?
- What test proves the change works?
- What rollback path exists if the output is wrong?

Route Hermes Behind A Gateway
Section 5
Route Hermes Behind A Gateway
A gateway lets Hermes handle cheap routine work while escalating hard tasks to stronger cloud models.
- 1Name the job before naming the tool.
- 2Write the smallest useful scope the agent can finish.
- 3Run the result as a user, not as a fan of the tool.
- 4Inspect the diff, data access, and failure path before sharing.
Use this as the working prompt or checklist for the lesson.
Create routing rules: local Hermes for summaries, cloud model for code edits touching auth, reject any prompt containing secrets unless local-only.- What should the user be able to do when this is finished?
- What data should the app or agent never expose?
- What test proves the change works?
- What rollback path exists if the output is wrong?
Section 6
Evaluate Hermes On Your Workflow
Section 7
Evaluate Hermes On Your Workflow
Do not ask whether Hermes is good. Ask whether it wins on your exact prompts, schemas, and failure cases.
- 1Name the job before naming the tool.
- 2Write the smallest useful scope the agent can finish.
- 3Run the result as a user, not as a fan of the tool.
- 4Inspect the diff, data access, and failure path before sharing.
Use this as the working prompt or checklist for the lesson.
Build 20 examples for one workflow. Score exactness, schema validity, latency, and cost. Compare Hermes against your current model.- What should the user be able to do when this is finished?
- What data should the app or agent never expose?
- What test proves the change works?
- What rollback path exists if the output is wrong?
Section 8
Memory Boundaries For Hermes Agents
Section 9
Memory Boundaries For Hermes Agents
A local model can still leak data if the harness feeds it the wrong context. Memory should be scoped by task and sensitivity.
- 1Name the job before naming the tool.
- 2Write the smallest useful scope the agent can finish.
- 3Run the result as a user, not as a fan of the tool.
- 4Inspect the diff, data access, and failure path before sharing.
Use this as the working prompt or checklist for the lesson.
Design memory scopes: public docs, project notes, private customer data. Define which Hermes workflows can read each scope and which cannot.- What should the user be able to do when this is finished?
- What data should the app or agent never expose?
- What test proves the change works?
- What rollback path exists if the output is wrong?
