error-propagation SKILL.md skillA
error-propagation from hoangsonww/claude-code-agent-monitor is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add hoangsonww/claude-code-agent-monitor/error-propagation@git:20260804.9eab0d7Pins git:20260804.9eab0d7 in mdr.lock. Pin the fingerprint instead.

Trace error propagation through a multi-agent session by agent depth — where failures originated, the depth at which they appeared, and how they cascaded up to parent agents — using the Agent Monitor workflow intelligence API and the session event stream. Use when a multi-agent run failed and you need to find the origin and blast radius of the failure.
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
# Error Propagation
Trace where a multi-agent session's failures started and how far they spread.
## Input
The user provides: **$ARGUMENTS**
A session ID. If empty, fetch `GET /api/sessions?limit=1`, but prefer the most recent session whose `status` is `error` or `abandoned`; state which one you picked.
## Data Sources
| Endpoint | Returns |
|----------|---------|
| `GET /api/workflows/{sessionId}` | The `errorPropagation` dataset: failures grouped by agent depth, with originating depth and cascade paths to parents |
| `GET /api/events?session_id={sessionId}` | The event stream — corroborate with `APIError`, `SubagentStop`, and failing `PostToolUse` events (`event_type`, `tool_name`, `summary`, `timestamp`) |
## Report Sections
### 1. Failure Summary
From `errorPropagation`: total errors, the depth where the first error originated, and how many distinct agents were affected.
`Origin depth: d · Errors: N · Agents affected: M`
### 2. Errors by Depth
| Depth | Errors originated | Errors inherited from children | Net failing agents |

How to install
mdr add hoangsonww/claude-code-agent-monitor/error-propagation@sha256:2b55594c9868b71aThe line at the top of this page pins the label git:20260804.9eab0d7, 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.
