Research direction

Read the repository guidance and inspect the implementation of dependency #13 (B01-01) to find where this roadmap item belongs. First resolve the decision gate for scope, bounds, and confidence reporting; the issue names no files or tests to start from. Done means a bounded, read-only scan covers the listed risk areas and reports path and confidence, with both verification cases passing.

Written by the indexing model from the issue text.

Description

enhancement status:approved

Goal

Build a deterministic, read-only, bounded scanner that flags contextual risk (prompt-injection heuristics, not a guarantee) across scripts, hooks, actions, invisible unicode, and encoded payloads.

Observations

  • Baseline gitleaks already covers secret keys; B06 adds contextual risk analysis, not a duplicate scanner.
  • Prompt-injection heuristics reduce risk but cannot guarantee detection.
  • The scanner must be read-only and bounded in time and output.

Decision gate

Approve scope, bounds, and confidence reporting before implementing detection rules.

Acceptance criteria

  • The scanner is read-only and bounded by explicit time and size limits.
  • Checks cover scripts, hooks, actions, invisible unicode, and encoded payloads with context.
  • Findings carry path and confidence, never a bare pass/fail.

Verification

  • Scan of a benign tree -> exit 0 with no findings.
  • Scan with a known encoded-payload fixture -> a finding with path and confidence.

Release checkpoint

Remaining risk: heuristics have false negatives; tests must not claim 100% malware detection or an unconditional LLM pass/fail.

Tracking

Roadmap item: B06-01. All acceptance criteria remain pending; publication does not grant approval or release authority.

Dependencies

  • Depends on #13 (B01-01).
