Forecast AI knowledge staleness loss

Forecast stale and unsupported AI answers plus economic-loss VaR/CVaR by learning tenant-local knowledge-change hazards, retrieval failure and lognormal stale-loss severity, then simulating scheduled refreshes under coherent demand/change/loss scenarios and a shared index-failure state.

What it's for

Prices the hidden liability behind a RAG dashboard: how often answers are likely to be stale or unsupported, what that costs, and how ugly the correlated downside becomes when the index itself fails.

How it works

Forecasting & survival — Estimate when something completes or fails, with censoring and unresolved work handled honestly rather than dropped.

  1. 1 Validate consecutive zero-inclusive domain-period history and fit Gamma source-change hazards, Beta retrieval-failure rates and partially pooled lognormal positive stale-loss severity from tenant data and governed priors.
  2. 2 Draw one common operating scenario and index-failure state per Monte Carlo path, then simulate daily source changes, scheduled refreshes, queries, unsupported retrieval and stale exposure for every domain.
  3. 3 Aggregate correlated paths into domain and portfolio stale fractions, breach probabilities, expected loss and economic-loss VaR/CVaR; abstain when local history or evidence is insufficient.

Before you trust it

Every tool in the catalog ships with the conditions under which its answer is meaningful — and the conditions under which it should abstain instead of guessing.

Assumptions & guardrails

  • Training examples precede their outcomes, censoring and unresolved work are represented, and deployment populations remain comparable to validation cohorts.
  • Knowledge domains, refresh definitions, zero query/change periods, mature stale labels, positive loss marks and common scenarios share a stable prospective horizon.
  • A predictive interval or risk estimate is not a deadline promise, causal explanation, or individual-performance judgment.
  • This conditional system forecast neither certifies factual truth nor attributes blame; do not transfer fitted rates or losses between tenants.

Minimum evidence

  • domain_history: required and organization-defined
  • current_domains: required and organization-defined
  • scenarios: required and organization-defined

How to validate it

Use chronological train/calibration/test windows, compare proper scores and decision value with a simple baseline, and recalibrate only from outcomes resolved after prediction time.

Calibrating it to your org

Same for everyone

The mathematical kernel, validation rules, method version, and JSON output semantics are organization-independent; no tenant-trained coefficients or company benchmark is embedded in the function.

Specific to you

  • stable knowledge-domain period spine joined to complete source change/version, scheduled refresh, query evaluation and finance loss histories without dropping zero periods, unresolved outcomes or common index incidents
  • domain/version epoch, stale/unsupported label and maturity, exposure/change/refresh semantics, loss perimeter, tenant priors, horizon/cadence, query/value plan, coherent scenario law, common index failure, evidence/support gates and tail appetite

Calibration workflow

  1. 1 Define the management decision, target outcome, aggregate unit, privacy boundary, cadence, and prediction/intervention horizon for this organization.
  2. 2 Build a tenant-scoped historical cohort using only information available before each prediction or decision; preserve zero periods, censoring, assignment probabilities, and unresolved outcomes when the method requires them.
  3. 3 Estimate statistical parameters on training history, but obtain costs, utilities, risk tolerance, practical-effect thresholds, capacity, and policy constraints from accountable decision owners.
  4. 4 Validate on later time windows or held-out aggregate units at the deployment grain, against a simple baseline and the function-specific validation strategy.
  5. 5 Deploy only if the returned decision clears evidence, overlap, calibration, robustness, and guardrail checks; warning, unsupported, schema-gap, and fallback decisions are abstentions.
  6. 6 Monitor realized outcomes, data drift, coverage, and decision regret; recalibrate at a governed cadence or after a detected regime/definition change, never merely because a stakeholder dislikes the result.

Call it from your AI

You don't wire up 388 tools in your MCP client. The GitRevio MCP server exposes 18 tools, three of which let an agent search the catalog, read a tool's schema, and run it — so the assistant finds this one on its own.

gitrevio_capabilities_search
  { "q": "forecast stale and unsupported ai answers" }
  → finds "forecast_ai_knowledge_staleness_loss"

gitrevio_capability_describe
  { "capability_id": "forecast_ai_knowledge_staleness_loss" }
  → returns the input schema and agent guidance shown on this page

gitrevio_capability_run
  { "capability_id": "forecast_ai_knowledge_staleness_loss", "arguments": { ... } }
  → returns the result shown above

Works in Claude Desktop, Claude Code, Cursor, Cline, Continue.dev, Goose and Aider. See the MCP server.
