Component-level agent evaluation

Planner quality assessment

Determine whether plans are feasible, sufficiently complete, and bounded

When a planner produces steps that look plausible but fail in execution, this area becomes relevant. For the agent planning and evaluation lead, the concern is specific: a plan assumes a permission or tool result that has not been established. The deployment evaluation starts from that consequence and follows the relevant evidence through the customer workflow. Assess the plan against executable constraints rather than style. A concise plan can be sufficient, and a detailed plan can still be invalid if it relies on unavailable tools, missing authority, or unsupported assumptions.

Connect the operating question to inspectable evidence

  1. Agent planning and evaluation lead

    Owns the bounded decision and the consequence of acting.

  2. Task goals

    Defines the starting context for the proposed work.

  3. Missing prerequisites

    Exposes the first material uncertainty to examine.

  4. Replanning test cases

    Carries unresolved conditions into an accountable next action.

Evaluation findings apply to the tested deployment, cases and configuration; they do not approve release.

For the agent planning and evaluation lead, this becomes relevant when a planner produces steps that look plausible but fail in execution. The immediate decision is whether plans are feasible, sufficiently complete, and bounded. The scope should be narrow enough that the evaluation team can identify a meaningful alternative, including continuing the current approach if the available evidence already supports it.

The practical failure to challenge is that a plan assumes a permission or tool result that has not been established. That concern gives the work a concrete direction: establish what the relevant boundary should do, inspect how it behaves or would operate, and identify the owner of any gap. It should not be diluted into a broad transformation exercise before the specific question has been answered.

Review questions—not evidence of completed testing.

Missing prerequisites

For this scope, missing prerequisites should be examined alongside task goals. Give the planner tasks with explicit prerequisites and inspect whether it establishes them before proposing dependent actions. A missing permission, unavailable tool, or unverified fact can make a plausible plan infeasible. The proposed rubric should identify the specific unsupported dependency rather than score plan detail as quality.

Invalid step order

For this scope, invalid step order should be examined alongside tool and dependency constraints. Test step ordering where one action changes the validity of another. Preserve expected dependencies and inspect whether execution follows the plan or improvises around it. This helps distinguish a planning defect from an execution defect and reveals plans that succeed only because later components repair their mistakes.

Replanning after new evidence

For this scope, replanning after new evidence should be examined alongside accepted plan and outcome criteria. Introduce new evidence that invalidates an assumption and observe replanning. The agent should revise, clarify, or stop according to the task contract. The evaluation should inspect whether obsolete steps remain active or whether the planner can explain why the revised path is now appropriate.

Prerequisites

Start with task goals

Give each input a specific job

Context neededTask goals
Defines the operating boundary.
Examination materialTool and dependency constraints
Examine invalid step order.
Operating dependencyAccepted plan and outcome criteria
Shows conditions affecting replanning after new evidence.
ParticipationProduct or platform owner
Confirm access and a reviewer who can resolve gaps.
Use sanitised material; preserve evidence gaps.

The starting material is task goals, tool and dependency constraints, and accepted plan and outcome criteria. Review these together rather than assuming one document tells the whole story. A stated rule may differ from a configured behaviour, and a proposed responsibility may not yet have an available owner. Identify those differences before selecting the detailed work.

Participation should include a product or platform decision owner, a technical lead, a data owner, and a competent reviewer for the relevant boundary. The customer should define which information and environments may be used. Synthetic or sanitised examples can support preparation when they preserve the relevant behaviour; if they omit a material dependency, record the limitation and agree how the missing evidence would be obtained.

How the work proceeds

Tie the deployment finding to observable behaviour

Follow the evidence through the work

  1. Missing prerequisites

    Use task goals to define the decision criteria.

  2. Invalid step order

    Inspect tool and dependency constraints and retain observations that challenge the expected result.

  3. Replanning after new evidence

    Use accepted plan and outcome criteria to identify unresolved conditions and a responsible owner.

  4. Replanning test cases

    Link the recommendation to its evidence, remaining limits and next validation condition.

The sequence is adapted to the system, decision and authorised access.

Evaluate plans against available tools, required evidence, dependencies, and authorised actions. Include tasks where an early assumption is contradicted later so replanning can be observed. The proposed rubric should distinguish a plan that is incomplete but recoverable from one that cannot succeed without violating a constraint.

A practical first slice would focus on missing prerequisites and then follow its consequences into invalid step order. Keep replanning after new evidence visible as a separate review question rather than assuming it is satisfied by the first result. The evaluation team should record observations, competing explanations, and changes to the original assumptions. A second reviewer can challenge whether the evidence supports the recommendation and whether an apparently successful example omitted the condition that matters most.

Illustrative scenario

Resolution planned too early: revise, clarify or stop

Examine the constructed decision boundary

Illustrative scenario

  1. Resolution planned too early

    An agent plans an update before obtaining the required eligibility evidence.

  2. Unavailable prerequisite

    Withhold eligibility and inspect replanning and any later attempted action.

  3. Revise, clarify or stop

    Follow the task contract instead of carrying the unsupported assumption into execution.

Illustrative scenario; no observed result implied.

Consider an illustrative situation in which an agent plans to resolve a case before checking the evidence needed for an authorised update. This is a constructed example, not a client engagement or an observed Softlander outcome.

For the prematurely planned case resolution, an illustrative run would make eligibility evidence unavailable. The planner should revise, clarify, or stop according to the task contract. The reviewer would inspect whether later execution compensates for a weak plan or simply carries an unsupported assumption into a tool action.

The useful learning would be the difference between the expected behaviour and the behaviour or responsibility actually demonstrated. If the exercise leaves replanning after new evidence unresolved, that should remain a named next step. A recommendation to narrow the scope, improve a prerequisite, or hold the decision can be appropriate when the example exposes a material dependency.

Indicative outputs include planner quality rubric, feasibility and sequencing findings, and replanning test cases. Their form should follow the decision and the customer’s existing operating records. The first should establish the assessed boundary and relevant observations; the second should make material gaps or dependencies inspectable; the third should identify the action, owner, and evidence needed to revisit the decision.

Acceptance should be tested through use: can the responsible owner explain what was examined, identify an unresolved issue, and act on the next step without reconstructing the whole engagement? Findings should preserve counterevidence and limits. A polished document is insufficient if it does not help resolve the customer’s specific question.

A little more clarity

Questions to consider.

Start with the questions that shape a better decision.

What makes an agent plan feasible?

Evaluate plans against available tools, required evidence, dependencies, and authorised actions. Include tasks where an early assumption is contradicted later so replanning can be observed. The proposed rubric should distinguish a plan that is incomplete but recoverable from one that cannot succeed without violating a constraint.

How should missing prerequisites be tested?

Give the planner tasks with explicit prerequisites and inspect whether it establishes them before proposing dependent actions. A missing permission, unavailable tool, or unverified fact can make a plausible plan infeasible. The proposed rubric should identify the specific unsupported dependency rather than score plan detail as quality.

When should new evidence trigger replanning?

Introduce new evidence that invalidates an assumption and observe replanning. The agent should revise, clarify, or stop according to the task contract. The evaluation should inspect whether obsolete steps remain active or whether the planner can explain why the revised path is now appropriate.

Why is plan detail not a quality measure by itself?

Assess the plan against executable constraints rather than style. A concise plan can be sufficient, and a detailed plan can still be invalid if it relies on unavailable tools, missing authority, or unsupported assumptions.

How should invalid plans be connected to execution effects?

Test step ordering where one action changes the validity of another. Preserve expected dependencies and inspect whether execution follows the plan or improvises around it. This helps distinguish a planning defect from an execution defect and reveals plans that succeed only because later components repair their mistakes.

What would the planner quality rubric make clear?

It should connect the specific concern—a plan assumes a permission or tool result that has not been established—to what was examined and what remains unresolved. The record should separate observations from proposed changes and identify the owner responsible for the next evidence. It is a decision aid within the agreed scope, not a broader assurance conclusion.
