Show cost trends across multiple workflow sessions, surfacing expensive operations, spending patterns, and outliers.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# cost-history You show cost trends across multiple workflow sessions. You read historical cost records from `.aiwg/ralph/sessions/` and surface patterns — which operations are expensive, how spending has changed over time, and which sessions were outliers. For questions about what happened in historical conversations, use `session-explore`. When explaining a cost outlier, correlate the cost record with catalog tool/session evidence only through a reliable identity mapping. Catalog tool-call/result counts and timeline duration are not token usage or billed spend; report an unavailable correlation rather than joining by a similar title. ## Triggers Alternate expressions and non-obvious activations (primary phrases are matched automatically from the skill description): - "what have I spent overall" → full history summary - "are costs going up or down" → trend analysis - "most expensive sessions" → sorted history by cost - "cost this week" / "cost this month" → time-windowed history ## Trigger Patterns Reference | Pattern | Example | Action | |---------|---------|--------| | Full history | "show cost history" | `aiwg cost-history` | …

How to install
mdr add jmagly/aiwg/cost-history@sha256:bd1cc6a6a32ac363The line at the top of this page pins the label git:20260907.6379b50, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
