# Agent: The API Diplomat

## 1. High-Level Concept
**The API Diplomat** is an autonomous agent dedicated to maintaining the "Foreign Relations" of your software stack. It treats every external API integration as a diplomatic relationship that must be actively managed, negotiated, and updated.

Unlike simple monitoring tools that alert when things break, the Diplomat proactively researches upcoming changes (by reading documentation/changelogs), verifies compliance (by running contract tests), and even drafts "Amendments" (SDK updates) when the foreign power (the API provider) changes their laws (schema).

## 2. Core Toolset
- **fetch**: To conduct "Diplomatic Visits" (Poll endpoints) and verify the current state of the API.
- **web**: To gather "Intelligence" (Search changelogs, developer blogs, migration guides).
- **filesystem**: To maintain the "Treaties" (OpenAPI specs, SDK code, Mock files).
- **memory**: To build a "State of Relations" graph (Provider Reliability, Version History, Volatility Index).
- **shell**: To run "War Games" (Integration tests) to verify if the new treaty holds.

## 3. The Diplomatic Loop
The agent runs in a continuous "State of Relations" cycle:

### Phase A: Intelligence Gathering (Web)
1.  **Surveillance**: Periodically searches the web for "Provider X API changelog", "deprecation notice", or "migration guide".
2.  **Analysis**: If a new version or breaking change is detected in text, it flags the Provider as "Volatile" in Memory.

### Phase B: Contract Verification (Fetch)
1.  **Patrol**: Executes a suite of non-destructive "Contract Tests" against the live API.
2.  **Comparison**: Validates the response against the local `openapi.yaml` or type definitions.
3.  **Drift Detection**: If a field changes (e.g., `id` becomes `string`), it records the specific deviation.

### Phase C: Treaty Renegotiation (Filesystem)
1.  **Drafting**: If a drift is detected or a changelog suggests a fix:
    - It updates the local OpenAPI spec.
    - It attempts to patch the TypeScript/Python client (e.g., updating a type definition).
2.  **Ratification**: It runs the project's test suite with the new code.
    - *Success*: Commits the change as "chore(api): update User schema per v2 migration".
    - *Failure*: Reverts and generates a "Diplomatic Incident Report" for human review.

## 4. Memory Architecture: The Relations Graph
The agent builds a persistent graph in the Memory Server:

- **Nodes**: `Provider` (Stripe), `Endpoint` (/v1/charges), `Field` (amount), `Incident` (500 Error).
- **Edges**:
    - `Provider HAS_RELIABILITY Score(0-100)`
    - `Endpoint EXHIBITS DriftType(TypeChange)`
    - `Incident LINKED_TO ChangelogUrl`

This graph allows the agent to answer questions like: *"Which integration has been most unstable this month?"* or *"Did we update the Stripe SDK after their October announcement?"*

## 5. Failure Modes & Recovery
- **The "False Flag" Operation**: The API is temporarily down (503), but the agent thinks the schema changed.
    - *Fix*: The agent checks the "Status Page" (Web) before assuming a schema change.
- **The "Bad Translation"**: The agent updates a type definition but misses a subtle behavioral change (e.g., date format).
    - *Fix*: Rely on the project's existing test suite. If coverage is low, the agent requests human review instead of auto-committing.

## 6. Human Touchpoints
- **Ambassador Appointment**: The human must initially register the API keys and the location of the `openapi.yaml`.
- **Treaty Ratification**: Ideally, the agent opens a Pull Request. The human is the final signatory (Merge).
- **Sanctions**: The human can tell the agent to "Ignore" specific endpoints that are known to be flaky.

## 7. Real-World Use Case
A team maintains a dashboard integrating 15 different SaaS tools (Salesforce, HubSpot, Stripe, etc.).
- **Without Agent**: A provider deprecates a field. The dashboard crashes. A dev spends 4 hours debugging, finding the changelog, and fixing the type.
- **With Diplomat**: The agent noticed the deprecation notice 2 weeks ago, created a PR to switch to the new field, and the team merged it before the crash ever happened.
