From f6f64e1541b952392c3e3c94cb80ff3b7c2c2906 Mon Sep 17 00:00:00 2001 From: Thando Mini Date: Fri, 26 Jun 2026 20:08:52 +0200 Subject: [PATCH 1/4] feat(security): knowledge base + multi-tool scanner runner (internal/security) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit New package backing vxd's security agent: - knowledge.go: growable, JSON-persisted KnowledgeBase seeded with OWASP Top 10 (2021) + high-value CWEs (hardcoded secrets, path traversal, XSS), each with detection + remediation guidance. Add() is immutable + version-bumping + dedup-by-ID (the self-upskilling store). Checklist() renders for prompts. - scanners.go: orchestrates gosec/govulncheck/gitleaks/semgrep/npm-audit with language-aware applicability + PATH detection (graceful degrade). Pure parsers per tool turn real scanner output into Findings — no hallucinated vulns. - languages.go: manifest + extension language detection (ts vs js aware). - finding.go/severity.go/report.go: findings model, severity ranking with scanner-synonym parsing, dedup, and an operator-facing markdown report. TDD: 16 tests (KB roundtrip/immutability/lang-filter/checklist, scanner applicability, all 5 parsers against representative output, report counts/format). vet + golangci-lint clean. --- internal/security/finding.go | 39 ++++ internal/security/knowledge.go | 258 ++++++++++++++++++++++ internal/security/knowledge_test.go | 174 +++++++++++++++ internal/security/languages.go | 86 ++++++++ internal/security/report.go | 100 +++++++++ internal/security/report_test.go | 55 +++++ internal/security/scanners.go | 317 ++++++++++++++++++++++++++++ internal/security/scanners_test.go | 207 ++++++++++++++++++ internal/security/severity.go | 55 +++++ 9 files changed, 1291 insertions(+) create mode 100644 internal/security/finding.go create mode 100644 internal/security/knowledge.go create mode 100644 internal/security/knowledge_test.go create mode 100644 internal/security/languages.go create mode 100644 internal/security/report.go create mode 100644 internal/security/report_test.go create mode 100644 internal/security/scanners.go create mode 100644 internal/security/scanners_test.go create mode 100644 internal/security/severity.go diff --git a/internal/security/finding.go b/internal/security/finding.go new file mode 100644 index 0000000..4d85fd1 --- /dev/null +++ b/internal/security/finding.go @@ -0,0 +1,39 @@ +package security + +import "fmt" + +// Finding is a single security issue surfaced by a scanner or the LLM review. +type Finding struct { + Tool string `json:"tool"` // "gosec", "semgrep", "govulncheck", "gitleaks", "npm-audit", "llm" + RuleID string `json:"rule_id"` // tool rule id, CWE, or OWASP category + Severity Severity `json:"severity"` // serialised as its int rank + File string `json:"file"` + Line int `json:"line"` + Title string `json:"title"` + Detail string `json:"detail"` + Category string `json:"category,omitempty"` // OWASP category when known + Source string `json:"source"` // "scanner" | "llm" +} + +// key identifies a finding for deduplication across overlapping tools. +func (f Finding) key() string { + return fmt.Sprintf("%s|%s|%s|%d", f.Tool, f.RuleID, f.File, f.Line) +} + +// DedupeFindings removes exact duplicates (same tool, rule, file, line), +// preserving first-seen order.

Continuous upskilling: confirmed high+ findings whose vuln CLASS (CWE, else OWASP category, else tool rule) isn't already covered are added to the knowledge base as learned rules (KnowledgeBase.Covers matches ID or CWE so OWASP-indexed baseline classes aren't re-learned), persisted, and announced via SECURITY_RULE_LEARNED — so every future build inherits classes found in past ones. New events STORY_SECURITY_PASSED/FAILED + SECURITY_SCAN_COMPLETED/RULE_LEARNED wired into the projection switch (TestProject_AllDeclaredEventsHandled passes). TDD: 7 tests (scan aggregation+event, block-on-critical, pass-below-threshold, self-upskill on new class, no-relearn known class, LLM findings parse).

All three are verified working on the Claude CLI subscription tier. - **Default execution tiers are all-Anthropic (2026-06-24 fix).** `DefaultConfig` previously set junior/intermediate/supervisor to `{google, gemma-4-27b-it}` — a model that 404s on the Google AI API (it does not exist on `v1beta`). Every low-complexity story spawned a gemini agent that died in ~10s producing no code, then limped forward by escalating to senior. Defaults are now `{anthropic, claude-haiku-4-5}` so a fresh install works with only the Claude CLI configured (no Google AI key/quota). `TestDefaultConfig_NoInvalidJuniorModel` pins this. **A model 404 in the agent runtime surfaces as "agent produced no code changes," NOT as a model error — if a whole tier silently produces nothing, validate the model ID with `gemini -m -p OK` / `claude --model -p OK` first.** diff --git a/README.md b/README.md index d69c872..ae72ba6 100644 --- a/README.md +++ b/README.md @@ -391,6 +391,7 @@ Run `vxd init` to generate `vxd.yaml` with sensible defaults, then customize: | `runtimes` | Map of named CLI runtime definitions — command, args, supported models, and idle/permission detection patterns | Includes built-in entries for `claude-code`, `codex`, `gemini`, `swe-agent`; each supports optional `runner: docker\|ssh` | | `billing` | Hourly consulting rate, currency, Fibonacci-to-hours range mapping, and LLM cost accounting mode | `default_rate: 150.0`, `currency: USD`, `llm_costs.mode: subscription` | | `qa` | Declarative success criteria evaluated after each story (output_contains, file_exists, file_contains, exit_code_zero, etc.); `disable_pre_merge_verify` (turn off the per-story pre-merge build/test gate); and the requirement-completion gate — `disable_completion_gate` (turn off) + `completion_fix_cycles` (auto-fix attempts against a red composed mainline before blocking; `0`→default 2, negative→hard gate).

The per-story gate now pauses a build only on CRITICAL findings (leaked secrets via gitleaks, LLM-confirmed injection/hardcoded credentials) — high-signal where it counts.
