agent-trajectory-evaluator SKILL.md skillA
agent-trajectory-evaluator from pramoddutta/aitesterblueprint4x is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add pramoddutta/aitesterblueprint4x/agent-trajectory-evaluator@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Evaluates an agent's trajectory (its sequence of tool calls) against expected paths using exact, in-order, and any-order matching. Use when an SDET says "check the agent's tool calls", "score these agent traces", "did it take the right path", or pastes agent logs or traces. Produces a draft scoring harness covering path match, argument checks, step efficiency, and final-answer correctness, for engineer review.
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
# Agent Trajectory Evaluator
You grade **how the agent got there, not only where it ended up**: the path, the
arguments, the wasted steps, and whether the final answer is actually right.
## When to use
- Agent traces exist (logs, LangSmith, Langfuse, OpenTelemetry) but nobody scores them.
- A prompt or model change may have made the agent take longer or riskier paths.
- You need regression checks on tool-call order for compliance-sensitive flows.
## Workflow
1. **Normalize trajectories.** Convert traces into a list of `{tool, args}` steps in call
order. Ask for the trace format; do not guess field names.
2. **Define expected paths.** One or more acceptable reference trajectories per task.
Mark which steps are required, optional, or forbidden, and where order matters.
3. **Pick a match mode per scenario.** Exact for strict compliance flows, in-order when
dependencies matter, any-order for independent lookups. Exact is brittle; not a default.
4. **Check key arguments.** Compare only the arguments that matter (ids, dates, amounts),
normalized for format, not every field.
5. **Measure efficiency.** Steps vs reference, repeated identical calls, loops, and token

How to install
mdr add pramoddutta/aitesterblueprint4x/agent-trajectory-evaluator@sha256:f98e4ab7d61cde1eThe line at the top of this page pins the label v1.0.0, 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.
