Summary: WikiSkill proposes a framework that co-evolves agent skills with a persistent knowledge base (wiki), separating raw execution experience, accumulated knowledge, and executable skills. This architecture directly maps to gh-aw's existing skill system, repo-memory, and cache-memory but could be significantly enhanced.
Concrete Improvements:
1.1 Skill Wiki Knowledge Base
What: Implement a persistent knowledge base (wiki) that consolidates workflow execution experience into reusable knowledge. Each skill would maintain its own wiki section with learned patterns, common pitfalls, and optimization strategies.
Implementation: Add .github/skills/<skill>/WIKI.md alongside SKILL.md; compiler reads WIKI.md as additional context when skill is loaded; automated consolidation from workflow execution logs into wiki entries.
Impact: High - Enables cross-workflow learning and systematic skill improvement.
1.2 Skill Versioning & Evolution Tracking
What: Track skill versions explicitly with lineage and performance metrics. Allow skills to evolve through experience while maintaining backward compatibility.
Implementation: Add version field to skill frontmatter; maintain skill-performance.json in repo-memory tracking success rates per version; automated skill evolution proposals based on failure patterns.
Impact: Medium-High - Enables data-driven skill improvement and A/B testing.
1.3 Experience-to-Skill Pipeline
What: Build automated pipeline that mines workflow execution logs (repo-memory, cache-memory) to identify patterns and consolidate them into skill updates or new skill proposals.
Implementation: Create gh aw learn command that analyzes execution logs, clusters common patterns, and generates skill update proposals; integrate with existing repo-memory structure.
Impact: High - Automates skill discovery and evolution from real usage.
1.4 Separation of Experience, Knowledge, and Skills
What: Formalize three-layer architecture: (1) execution traces in cache-memory, (2) consolidated knowledge in skill wikis, (3) executable skill definitions in SKILL.md files.
Implementation: Document architectural pattern in AGENTS.md; update skill authoring guide; add validation that skills properly separate concerns.
Impact: Medium - Improves clarity and maintainability of skill system.
Summary: HarnessLens introduces budget-aware, behavior-aware verification for agent harness evolution. Instead of running all tests on every change, it selectively verifies candidates on behavior-relevant tasks using an attributable-evidence gate. This directly applies to gh-aw's workflow development and validation process.
Concrete Improvements:
2.1 Behavior-Aware Workflow Testing
What: Implement intelligent test selection that identifies which workflow changes affect which behaviors, then runs only relevant tests during development.
Implementation: Extend gh aw compile with --test-behavior flag; maintain behavior-test mapping in workflow metadata; derive behavior impact from diff analysis of workflow markdown.
Impact: High - Dramatically reduces test time during workflow iteration.
2.2 Budget-Aware Validation
What: Add budget tracking (time, API calls, compute) to workflow validation with smart allocation across test scenarios based on change impact.
Implementation: Add budget configuration to workflow frontmatter; track resource usage per validation run; implement priority-based test execution that exhausts budget on highest-risk areas first.
Impact: Medium-High - Enables faster iteration within cost constraints.
2.3 Trajectory-Derived Workflow Modifications
What: Analyze workflow execution trajectories to automatically suggest workflow improvements or identify inefficient patterns.
Implementation: Add gh aw analyze command that reads execution logs and suggests workflow optimizations; integrate with existing agent-drain/log-mining pipeline.
Impact: Medium - Provides data-driven workflow optimization suggestions.
2.4 Attributable-Evidence Gate for Safe-Outputs
What: Before allowing safe-output operations, require attributable evidence from execution trajectory that the action is justified and safe.
Implementation: Extend safe-outputs validation to require evidence linking action to workflow goal and execution context; add evidence tracing to agent execution logs.
Impact: High - Improves safety and auditability of workflow actions.
3. When Context Gets Root: Privilege Escalation in LLM Harnesses
Summary: This paper identifies instruction privilege escalation attacks where agent harnesses elevate low-level malicious content to higher instruction levels during context construction. Critical security finding for gh-aw given its handling of untrusted workflow content, inline prompts, and shared imports.
Concrete Improvements:
3.1 Instruction-Level Privilege Tracking
What: Implement explicit privilege levels for different instruction sources (workflow frontmatter, inline prompts, shared imports, GitHub context, tool outputs) and track privilege through compilation.
Implementation: Add privilege field to instruction AST nodes in compiler; validate that low-privilege content cannot inject into high-privilege contexts; emit privilege-violation warnings during compilation.
Impact: Critical - Prevents privilege escalation attacks in workflows.
3.2 Context Construction Audit
What: Audit all points where gh-aw constructs LLM context to ensure privilege boundaries are maintained and low-privilege content cannot be elevated.
Implementation: Add security review checklist to SKILL.md for developer-security; scan compiler code for context construction; add automated tests for privilege escalation attempts.
Impact: Critical - Prevents exploitation of context construction vulnerabilities.
3.3 Inline Prompt Isolation
What: Strengthen isolation of inline prompts from surrounding workflow context to prevent them from gaining higher privileges through context blending.
Implementation: Add explicit privilege markers in compiled YAML around inline prompts; modify engine integrations to enforce privilege boundaries; document safe inline prompt patterns.
Impact: High - Hardens inline prompt security model.
3.4 Shared Import Privilege Model
What: Define and enforce privilege model for shared imports (e.g., imports from external repos) to prevent malicious imports from gaining full workflow privileges.
Implementation: Add privilege annotations to import frontmatter; enforce that imported content inherits restricted privileges; require explicit privilege grants for trusted imports.
Impact: High - Prevents supply-chain attacks via malicious shared imports.
3.5 Safe-Outputs Privilege Enforcement
What: Ensure safe-outputs operations cannot be triggered or influenced by low-privilege content (e.g., issue comments, PR descriptions).
Implementation: Add privilege requirements to safe-outputs tool definitions; validate that only high-privilege instructions can authorize writes; add privilege audit trail to safe-outputs logs.
Impact: Critical - Prevents unauthorized GitHub writes via privilege escalation.
