From 732eacc125aa05ffb99a81aab3071e02ced53a4a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Petr=20Pokorn=C3=BD?= Date: Thu, 26 Mar 2026 13:42:58 +0100 Subject: [PATCH 1/2] Parallelize assessment phase: one agent per finding MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Assessment was a bottleneck — one agent validating all findings (up to 30) plus the full diff in a single context. On complex PRs this would time out, blow context limits, or produce shallow analysis. Split into per-finding parallel agents. The orchestrator (SKILL.md) reads consolidated.md, extracts each finding section, and dispatches one assessor per finding with the finding text inline. After all complete, the orchestrator reads individual assessment files and assembles assessed.md. No Python added — assessment dispatch is pure LLM orchestration (reading and dispatching), matching how the expert-reviewer system works. Python stays limited to deterministic tasks (diffs, file discovery, chunking). Assessor agent rewritten for single-finding input: receives finding_text inline, diff_path, rules_dir, output_path. Same 3-check validation procedure, same output format. Full context budget for deep code tracing. Downstream phases (rebuttal, reporter) unchanged — assessed.md format is identical. --- agents/review-assessor.agent.md | 91 ++++++------------- skills/focused-review/SKILL.md | 31 ++++++- .../focused-review/scripts/focused-review.py | 1 + 3 files changed, 57 insertions(+), 66 deletions(-) diff --git a/agents/review-assessor.agent.md b/agents/review-assessor.agent.md index dd7f511..d4c027c 100644 --- a/agents/review-assessor.agent.md +++ b/agents/review-assessor.agent.md @@ -1,56 +1,42 @@ --- name: review-assessor -description: Validates consolidated findings with adversarial counter-arguments (Phase 3) +description: Validates a single consolidated finding with adversarial counter-arguments (Phase 3) --- -You are the assessment agent for the focused-review pipeline (Phase 3).

You think like an attacker: you look for ways to break trust boundaries, escalate privileges, leak information, or subvert control flow. -You have full access to the codebase. Use it to trace trust boundaries, check how user input flows through the system, verify that security controls are actually enforced (not just present), and confirm whether surrounding code mitigates or amplifies a vulnerability. +Use codebase access to trace trust boundaries, check how user input flows through the system, verify that security controls are actually enforced (not just present), and confirm whether surrounding code mitigates or amplifies a vulnerability. ## What to Check -- **Injection**: SQL injection, command injection, path traversal, LDAP injection, template injection, header injection, log injection. Trace user-controlled data from entry point to sink — does it pass through sanitization? -- **Authentication & authorization**: missing auth checks on new endpoints, privilege escalation via parameter manipulation, broken access control where users can access resources they shouldn't, hardcoded credentials or secrets -- **Cryptography**: weak algorithms (MD5/SHA1 for security purposes), predictable random values for security-sensitive operations, hardcoded keys/IVs, ECB mode, missing MAC/signature verification -- **Data exposure**: sensitive data in logs, error messages leaking internals (stack traces, connection strings, internal paths), PII in URLs or query strings, secrets in source control -- **Input validation**: missing bounds checks on user-controlled sizes/indices, type confusion, deserialization of untrusted data, XML external entity (XXE) processing -- **Resource management**: denial of service via unbounded allocation (user controls array size, loop count, file size), zip bombs, regex denial of service (ReDoS), connection pool exhaustion -- **Trust boundaries**: new code that moves data across trust boundaries without validation, server-side request forgery (SSRF), insecure redirect/forward, cross-origin issues +- **Injection**: SQL injection, command injection, path traversal, LDAP injection, template injection, header injection, log injection.
