CCS (Correctover Conformance Shape) runtime verification for AI agents — 7-dimension pre-execution checks at sub-25μs P50
Runtime verification for AI agents — 7 dimensions, sub-25μs P50, Ed25519 audit receipts
CCS (Correctover Conformance Shape) intercepts every tool call before execution and validates it across 7 dimensions: structure, schema, latency, cost, identity, integrity, and security. If something's wrong, it blocks — not after the damage, but before.
The AutoGen community proved it: prompt-based guardrails don't work. 56 days of testing showed every safety rule being bypassed by the agent itself, resulting in $106K in losses.
The fix? Enforcement must be structurally separate from the agent's process. That's exactly what CCS does.
npm install ccs-runtime
import { CCSVerifier } from 'ccs-runtime';
const ccs = new CCSVerifier({
block_on_failure: true,
latency_budget_us: 5000, // 5ms max execution time
cost_budget_usd: 0.10, // $0.10 max per request
});
// Catch SQL injection before it hits the database
const result = await ccs.verify({
tool_name: 'execute_sql',
tool_input: { query: "SELECT * FROM users; DROP TABLE users" },
});
// result.overall_pass === false
// result.blocked_dimensions === ['security']
Drop it into any agent framework as middleware:
import { CCSVerifier } from 'ccs-runtime';
const ccs = new CCSVerifier({ block_on_failure: true });
// Wraps any tool execution
const safeResult = await ccs.middleware(
{ tool_name: 'http_request', tool_input: { url: 'http://169.254.169.254/latest/meta-data/' } },
() => executeHttpRequest(url)
);
// Throws CCSError — SSRF blocked
| # | Dimension | What it checks |
|---|---|---|
| 1 | Structure | Tool call format validity |
| 2 | Schema | Input/output type conformance |
| 3 | Latency | Execution time budget enforcement |
| 4 | Cost | Token/USD budget per request |
| 5 | Identity | Caller identity verification |
| 6 | Integrity | Ed25519 payload signature |
| 7 | Security | Injection, RCE, SSRF, credential exfiltration |
| Rule | Detects | Severity |
|---|---|---|
| SEC-001 | Shell injection (;, ` | `, backticks) |
| SEC-002 | SSRF (internal IPs, cloud metadata) | BLOCK |
| SEC-003 | Cloud credential exfiltration (AWS/GCP/Azure keys) | BLOCK |
| SEC-004 | Path traversal (../, %2e%2e) | BLOCK |
| SEC-005 | SQL injection (SELECT/DROP/UNION patterns) | CRITICAL |
| SEC-006 | Command execution (eval/exec/system/spawn) | BLOCK |

CCS is an open verification standard progressing through IETF (draft-correctover-ccs-05). The runtime SDK is the reference implementation.
