Consolidates provider-specific AI costs into unified metrics across 5 providers: Anthropic, OpenAI, Google Gemini, GitHub Copilot, and Ollama (local/zero-cost).
Enable apples-to-apples cost comparison across AI providers for any given task, supporting model selection optimization (COST-003) and budget enforcement (COST-001).

Provider pricing is configured in src/config/providers.yaml.
Update that file when providers change their published rates.

COST-001 (cost_budgeter): Uses same rate structure patternpyyaml: providers.yaml loadingpytest: Test suiteThis skill participates in the framework's continuous improvement cycle (see skill-improvement-feedback).
When you use cost-aggregation during a task, include a skill_feedback entry in your HANDBACK to help improve it over time:
skill_feedback:
- skill_name: cost-aggregation
effectiveness_score: 0.85 # required: 0.0–1.0
clarity_score: 0.90 # optional
coverage_gaps:
- "Specific scenario the skill did not address"
improvement_suggestions:
- "Concrete change that would have helped"
usage_context: "One sentence on how you used this skill"
Positive feedback is as valuable as critical feedback. Three or more feedback items for this skill automatically trigger an improvement task.
Experiment orchestration framework with traffic allocation, statistical analysis, and early stopping detection. Use to test routing changes, model upgrades, and role assignments with Welch's t-test significance testing.
DEPRECATED — This skill is no longer maintained. Prometheus and Grafana infrastructure was never implemented. Use local JSON metrics analysis instead.
Scaffolds new SPEC-compliant agentic-engineers agents with a single call. Generates SKILL.md frontmatter, test scaffolds (TDD RED-phase), __init__.py, scripts/ layout, and DELEGATE/HANDBACK protocol templates. Use when creating any new automation agent, task handler, or operational tool. Validates role, model, effort, naming, and dependency graphs (circular dep detection) before writing files. Supports dry-run mode for planning without side effects.
Routine maintenance for Codex sessions: monitor queue state, close completed sub-agents, resume or escalate active work, and keep agent capacity available.
Automated cross-validation of protocol queue integrity. Scans all DELEGATEs/HANDBACKs, validates schema compliance, detects cycles, checks rate limits, generates compliance report. Enables self-referential protocol improvements.
Cost Budget Enforcement (COST-001) — enforces per-session, per-hour, and per-day AI spend limits across all agents and models. Blocks task execution when budgets are exceeded and emits structured alerts for operator action. Integrates with model-selection (COST-003) to pre-screen model choices against budget headroom.
