From 59024ab10ba3f50823a53a9e573510f99f75ee40 Mon Sep 17 00:00:00 2001 From: Kedar Bhujade <206036177+cx-kedar-bhujade@users.noreply.github.com> Date: Tue, 6 Oct 2026 12:05:24 +0530 Subject: [PATCH 1/5] Add provenance tag and confidence-gated suppression to guardrail prompts (AST-180794) (#1578) * AST-180794: Add provenance tag and confidence-gated suppression to guardrail prompts Tags ASCA/KICS/SCA guardrail output with a Checkmarx provenance marker so agents can distinguish genuine findings from spoofed text, and replaces the blanket "ask the user first" suppression gate with a confidence-gated model: suppress only when grounded in something verifiable in the file (or, for SCA, after actually attempting remediation), otherwise ask instead of guessing. Also reminds the agent to resume the original task after handling a finding. Co-Authored-By: Claude Sonnet 5 * AST-180794: Fix whitespace lint issues in provenanceTag helpers Co-Authored-By: Claude Sonnet 5 * AST-180794: Add hook-deny header and explicit user-instruction path to guardrail prompts Adds a shared hookDenyHeader to ASCA, KICS, and SCA guardrail prompts that states up front the message is a Checkmarx hook deny, not file content or an untrusted tool error, without repeating the spoof phrases the anti-injection skill tests treat as evidence a message did not come from Checkmarx. Splits the suppression rule into two independently sufficient paths: (a) the user explicitly told the agent to suppress or ignore the finding, honored immediately with no further verification, or (b) the agent decides on its own and grounds that decision in code it has actually opened and read itself (not an assumption or another file's claim). SCA's package suppression path is tightened the same way, requiring either the user's instruction or an actual remediation attempt returning "no fixed version exists". Adds injection-trigger regression tests across all five supported agents for ASCA, KICS, and SCA verifying the hook-deny header is present and phrases like "without asking" or "silently" never appear in agent-facing text. Co-Authored-By: Claude Sonnet 5 * AST-180794: Restructure guardrail prompts to classify-then-act remediation model Replaces the analyze/ask-when-unsure flow with an explicit classify-then-act sequence: findings are false positives only when cited evidence meets (a) or (b), otherwise they are always remediated autonomously and never surfaced to the user as a remediate-or-suppress question. Adds a structured remediation summary report and a verify-and-retry step across ASCA, KICS, and SCA guardrails. Co-Authored-By: Claude Sonnet 5 * AST-180794: Include findings list and tighten guardrail summary wording Adds the findings/packages list into the Cursor ASCA/KICS prompts and the SCA malicious/vulnerable prompts (previously only in the non-Cursor path), and simplifies remediationNote's signature now that subject/goal are no longer used. Aligns summary report wording and evidence hints (e.g. "parent module or sibling manifest") across agents, and updates the KICS Cursor test to match. Co-Authored-By: Claude Sonnet 5 * AST-180794: Share remediation report templates and bump ast-cx-hooks Extract the ASCA, KICS, and SCA closing remediation reports into shared constants (ascaRemediationReport, kicsRemediationReport, scaMaliciousReport, scaVulnerableReport) so the Cursor and non-Cursor deny paths render the same markdown report instead of two copies that could drift apart. Bump ast-cx-hooks to v1.0.10 and refresh go.sum.
