Rosentic

Cross-branch semantic conflict detection engine. Checks whether active git branches are compatible before merge. Detects function signature mismatches, HTTP route conflicts, GraphQL schema breaks, OpenAPI drift, and protobuf contract changes across 13 languages. Deterministic AST analysis, not AI review. Vendor-neutral: works regardless of which agent or IDE authored the branch.

Call it over A2A

A2A JSON-RPC: send SendMessage, then poll GetTask. Agent card: https://api.rosentic.com/.well-known/agent.json. Auth and limits are set by its operator.

curl -s https://api.rosentic.com/a2a -H 'Content-Type: application/json' -d '{"jsonrpc":"2.0","id":1,"method":"SendMessage","params":{"message":{"role":"ROLE_USER","messageId":"m1","parts":[{"text":"What can you do? Answer in three bullets."}]}}}'

How to call Rosentic over A2A

A2A 1.0 JSON-RPC: SendMessage returns a task or a message; poll a task with GetTask. The agent card at api.rosentic.com/.well-known/agent.json lists its skills and auth.

Python

import httpx, uuid

resp = httpx.post("https://api.rosentic.com/a2a", json={
    "jsonrpc": "2.0", "id": 1, "method": "SendMessage",
    "params": {"message": {"role": "ROLE_USER", "messageId": str(uuid.uuid4()),
                           "parts": [{"text": "What can you do? Answer in three bullets."}]}},
}, headers={"A2A-Version": "1.0"}, timeout=60)
print(resp.json())  # a Task (poll it with GetTask) or a direct Message

JavaScript

const res = await fetch("https://api.rosentic.com/a2a", {
  method: "POST",
  headers: { "content-type": "application/json", "A2A-Version": "1.0" },
  body: JSON.stringify({ jsonrpc: "2.0", id: 1, method: "SendMessage",
    params: { message: { role: "ROLE_USER", messageId: crypto.randomUUID(), parts: [{ text: "What can you do? Answer in three bullets." }] } } }),
});
console.log(await res.json());

Skills (5)

  • Assess Integration Posture assess_integration_posture
    Evaluate cross-branch conflict exposure for a repository with parallel agent branches: active branches, unverified branch pairs, agent attribution, estimated conflict surface, and whether merge-safety checking exists in CI. Scans run via t…
  • Check Cross-Branch Conflicts check_conflicts
    Cross-branch conflict detection for parallel agent branches: breaking function signature changes, HTTP route contract breaks, and schema drift that git merge will not catch. Deterministic AST analysis, UNSAFE/WARNING findings. Scans run vi…
  • Explain Conflict explain_conflict
    Explain one cross-branch conflict finding: which branches break each other, producer/consumer evidence, affected files and lines, and how to resolve before merge.
  • List Branches list_branches
    Active parallel branches with agent attribution, divergence from base, and commit metadata - see which agent holds which branch before checking cross-branch conflicts.
  • Merge Index merge_index
    Composite merge-safety score for a repo or org running parallel agents: historical cross-branch conflict trends, agent overlap, finding lifecycle, hotspot repos. Requires API key with Merge Index entitlement.
