Agent Action Gate Evidence Packet: What to Capture Before a Decision

The direct answer

Assemble reviewable evidence for a pre-action evidence and authority gate for agent tool use without turning assumptions or producer claims into proof. The working output is A claim-to-evidence packet with provenance, freshness, contradiction, and NOT_TESTED fields.

For Agent Action Gate, the bounded capability is a pre-action evidence and authority gate for agent tool use. Begin only when the team can supply the agent codebase, environment configuration, authority policy, and synthetic normal and failure cases. The documented delivery target is a deployed pre-action gate verified in the buyer's environment; anything broader requires a new scope and a new authority decision.

The copyable evidence packet

This evidence packet is for teams that need an agent to name its intended state change, consequence ceiling, permitted actions, and completion evidence before a tool runs. It begins with the agent codebase, environment configuration, authority policy, and synthetic normal and failure cases and stays inside the documented workflow: start-state capture, intended end state, consequence classification, admissible action set, evidence requirements, deny or escalate behavior, execution, and closeout. For Agent Action Gate, the evidence packet remains reviewable because its decisions have named owners, evidence fields, and stop conditions.

The Agent Action Gate evidence packet keeps each claim separate from its source and from the reviewer decision that accepts or rejects it. For this evidence-packet task, a URL or file name supplies provenance but not automatic proof; an executor saying “done” remains an assertion until a separate observation supports the exact criterion.

Machine-readable evidence row

{
  "claim_id": "CLM-01",
  "claim_type": "OBSERVED",
  "content": "All required fields exist before tool selection.",
  "evidence": "attach a direct readback or test receipt",
  "provenance": {
    "source": "named path or system",
    "observed_at": "ISO-8601",
    "method": "inspection or test"
  },
  "status": "NOT_TESTED",
  "contradictions": [],
  "reopen_if": "start state inferred instead of observed"
}

Contradiction rule

When two admissible records disagree, retain both and mark the claim REVIEW. Do not average incompatible observations or choose the convenient one. The human approver records what changed, which evidence applies to the current boundary, and what must be rerun. When required evidence is unavailable, the status stays NOT_TESTED.

Run the workflow as a sequence of decisions

The Agent Action Gate evidence packet follows this working sequence: start-state capture, intended end state, consequence classification, admissible action set, evidence requirements, deny or escalate behavior, execution, and closeout. Within this artifact, each phrase marks a state boundary for a pre-action evidence and authority gate for agent tool use. A stage output becomes the next named input, while a failed, missing, or unavailable check keeps the dependent evidence packet decision closed.

Separate failure register

• FAIL-01: Start state inferred instead of observed.
• FAIL-02: Consequence ceiling written after action selection.
• FAIL-03: Tool permission confused with business authority.
• FAIL-04: Done evidence defined as the agent's own confidence.
• FAIL-05: Unknown actions allowed by a broad fallback.

The register supplies negative cases for the complete acceptance set. A reviewer determines affected checks from observed evidence; array position never asserts that one failure proves or disproves one criterion.

The producer can explain what it attempted, but the human approver evaluates the evidence. If the artifact changes, its prior verdict expires. This is especially important for a pre-action evidence and authority gate for agent tool use, where a plausible narrative can hide a stale configuration, an untested negative case, or an authority mismatch.

Failure and recovery drills

A useful Agent Action Gate evidence packet explains what happens when its happy path breaks. These drills come from the accepted product truth record rather than a claim that every buyer has each failure. Use safe synthetic or authorized observations for a pre-action evidence and authority gate for agent tool use, and keep private credentials out of every fixture.

1. Start state inferred instead of observed.

Detect for Agent Action Gate: task owner captures a direct readback or safe fixture that makes this evidence packet condition observable. Its record binds source, time, method, and the current ART-20-02 fingerprint.

Contain the evidence packet: stop only the affected Agent Action Gate path after observing “start state inferred instead of observed”. Preserve its failed material and last verified state instead of erasing evidence or blindly repeating an external effect.

Recover and prove: apply the smallest authorized Agent Action Gate correction, then have a distinct reviewer re-evaluate the complete accepted check set. Do not select one check merely because it shares this failure's list position. If any affected evidence packet check cannot run, its result remains NOT_TESTED.

2. Consequence ceiling written after action selection.

Detect for Agent Action Gate: agent platform owner captures a direct readback or safe fixture that makes this evidence packet condition observable. Its record binds source, time, method, and the current ART-20-02 fingerprint.

Contain the evidence packet: stop only the affected Agent Action Gate path after observing “consequence ceiling written after action selection”. Preserve its failed material and last verified state instead of erasing evidence or blindly repeating an external effect.

Recover and prove: apply the smallest authorized Agent Action Gate correction, then have a distinct reviewer re-evaluate the complete accepted check set. Do not select one check merely because it shares this failure's list position. If any affected evidence packet check cannot run, its result remains NOT_TESTED.

3. Tool permission confused with business authority.

Detect for Agent Action Gate: security owner captures a direct readback or safe fixture that makes this evidence packet condition observable. Its record binds source, time, method, and the current ART-20-02 fingerprint.

Contain the evidence packet: stop only the affected Agent Action Gate path after observing “tool permission confused with business authority”. Preserve its failed material and last verified state instead of erasing evidence or blindly repeating an external effect.

Recover and prove: apply the smallest authorized Agent Action Gate correction, then have a distinct reviewer re-evaluate the complete accepted check set. Do not select one check merely because it shares this failure's list position. If any affected evidence packet check cannot run, its result remains NOT_TESTED.

4. Done evidence defined as the agent's own confidence.

Detect for Agent Action Gate: tool owner captures a direct readback or safe fixture that makes this evidence packet condition observable. Its record binds source, time, method, and the current ART-20-02 fingerprint.

Contain the evidence packet: stop only the affected Agent Action Gate path after observing “done evidence defined as the agent's own confidence”. Preserve its failed material and last verified state instead of erasing evidence or blindly repeating an external effect.

Recover and prove: apply the smallest authorized Agent Action Gate correction, then have a distinct reviewer re-evaluate the complete accepted check set. Do not select one check merely because it shares this failure's list position. If any affected evidence packet check cannot run, its result remains NOT_TESTED.

5. Unknown actions allowed by a broad fallback.

Detect for Agent Action Gate: human approver captures a direct readback or safe fixture that makes this evidence packet condition observable. Its record binds source, time, method, and the current ART-20-02 fingerprint.

Contain the evidence packet: stop only the affected Agent Action Gate path after observing “unknown actions allowed by a broad fallback”. Preserve its failed material and last verified state instead of erasing evidence or blindly repeating an external effect.

Recover and prove: apply the smallest authorized Agent Action Gate correction, then have a distinct reviewer re-evaluate the complete accepted check set. Do not select one check merely because it shares this failure's list position. If any affected evidence packet check cannot run, its result remains NOT_TESTED.

Ownership and handoff

For this Agent Action Gate evidence packet, the adjudication role is human approver. That role judges frozen acceptance evidence for a pre-action evidence and authority gate for agent tool use without becoming the product owner, legal adviser, security authority, or buyer. Its handoff retains open gaps, failed evidence, changed hashes, and the next action permitted for ART-20-02.

Evidence and acceptance

Use these product-specific statements as candidate acceptance checks:

• All required fields exist before tool selection.
• Authority and consequence checks fail closed.
• Synthetic unauthorized actions are denied.
• Done evidence is externally observable.
• Exceptions route to a named human decision.

For every Agent Action Gate evidence packet check, retain the tested object, environment or source, observation time, method, expected result, actual result, verifier identity, and artifact hash. In this ART-20-02 record, label a direct readback OBSERVED, a reproducible transformation COMPUTED, and an interpretation JUDGMENT; never merge those states into one confident claim.

The research packet observed 5 impressions across adjacent site queries such as “artificial intelligence can include all of the following except”, “recording which ai agent performed an action and which 'human' authorized the original task.”, “agent tool calling”, and “ai tool approval process” for the exact Search Console property https://sincllm.com/ during 2026-06-02/2026-08-30. Those observations help locate an existing audience vocabulary. They are not search-volume estimates, do not prove demand for this exact page, and do not predict clicks or rankings.

The product boundary remains controlling: A pre-action gate complements application authorization, sandboxing, monitoring, and human approval. It is not a complete security control.

Implementation checklist

• The evidence packet names the distinct reader job: Assemble reviewable evidence for a pre-action evidence and authority gate for agent tool use without turning assumptions or producer claims into proof.
• The input boundary is explicit: the agent codebase, environment configuration, authority policy, and synthetic normal and failure cases.
• The intended deliverable is explicit: a deployed pre-action gate verified in the buyer's environment.
• Every required acceptance check has current evidence or an honest NOT_TESTED status.
• At least one negative fixture covers start state inferred instead of observed.
• The human approver is distinct from the artifact producer.
• Rollback or reopen conditions are written before consequential action.
• No ranking, traffic, conversion, compliance, certification, or buyer-outcome guarantee was added.

When this Agent Action Gate evidence packet has a failed item, repair that named item and rerun its dependent checks. Keep the frozen threshold intact; the remaining checks cannot establish that the failed ART-20-02 condition probably holds.
