Reliability & compatibility
Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Declaring Intent
Overview
Before a critical action, say what you intend to do and the reasoning behind it, then act unless someone stops you. The value is that a reviewer can challenge the thinking before the action happens, not the wreckage after. The declaration also forces the actor to make the "why" and the "how will I know" explicit. For an agent, the stated intent is a proposal to be reviewed, never evidence that the agent actually understood.
Decision contract
- Claim checked: the declared intent names a falsifying signal (not just success), carries concrete abort criteria and a checked rollback, and the preconditions are proven rather than assumed before the action runs.
- Artifact observed: the intended action and target, the reasoning and precondition evidence, the expected result, and the abort/rollback criteria -> an intent declaration or
intent.md(action, reasoning, expected result, abort, rollback, decision rights, backup) and the actual-vs-expected result. - Decision affected: block -- whether a reviewer clears the critical or irreversible action before it runs, given expected result, abort criteria, and rollback.
- Failure class: unfalsifiable-intent (a stated goal with no falsifying signal, abort threshold, or verified rollback).
- Next action: stop when no rollback exists or abort criteria are unmeasurable; get a second reviewer when only one has seen the reasoning.
When to Use
- Before a deploy, migration, data change, public claim, dependency or model swap, or release.
- When an action is hard to reverse, or its blast radius is more than the immediate file.
- When you want a reviewer's eyes on the reasoning and the abort criteria before execution.
- When standing authority lets an agent proceed unless told no, and the team needs the "no" window.
When Not to Use
- The action is a routine, reversible edit with obvious proof and no trust boundary.
- An incident is live and the next move is stabilization, not a fresh proposal.
- Someone wants the declaration treated as a guarantee or certification.
Inputs
- The intended action and the exact target.
- The reasoning and the evidence that says the preconditions are met.
- The expected result, and the signals that would mean it went wrong.
- The abort and rollback criteria, the decision rights, and who is backing up the action.
Process
- Write the intent as "I intend to on because ."
- State the expected result and the precise signals that would falsify it.
- State the abort criteria and the verified rollback, in numbers where possible.
- Name who may stop the action, by when, and who is the backup watcher.
- Confirm the preconditions are actually proven, not assumed, before you proceed.
- Act only after the review window; then record the actual result against the expected one.
Outputs
- An intent declaration, or an
intent.mdrecord, with action, reasoning, expected result, abort criteria, rollback, decision rights, and backup. - The actual result compared to the expected result after the action.
- Any mismatch routed to a pause, an incident, or a deficiency entry.
Verification
- The declaration names what would prove it wrong, not just what success looks like.
- Abort and rollback criteria are concrete and the rollback has been checked.
- The actual result is compared to the expected result and the gap is recorded.
Escalation
- Escalate when the preconditions cannot be shown to be true before acting.
- Stop when no rollback exists or the abort criteria cannot be measured.
- Get a second reviewer when the action is irreversible and only one person has seen the reasoning.
Common Rationalizations
- "I said what I intend, so I am cleared to go." Declaration invites a challenge; it is not its own approval.
- "The agent's intent reads confidently." Confident wording is not understanding or evidence.
- "Rollback is probably fine." An unverified rollback is a gap, not a plan.
- "Abort criteria are obvious." If they are not written and measurable, they will not be obeyed under pressure.
Red Flags
- The intent states the goal but no falsifying signal or abort threshold.
- Preconditions are asserted ("checks passed") with no link to the evidence.
- The review window is zero because the work felt urgent.
- A reviewer approves the result without ever seeing the reasoning.
Prompt
Declare intent before this action the Nuclear-grade way.
Inputs:
- intended action and target:
- reasoning / evidence preconditions are met:
- expected result:
- abort criteria (numbers where possible):
- rollback (and is it verified?):
- who may stop it, by when / backup watcher:
Return:
- "I intend to on because "
- the expected result and the precise signals that would falsify it
- the abort criteria and the verified rollback
- the decision rights and the backup
- after acting: the actual result compared to the expected result, and any gap
State what would prove this wrong, not just what success looks like. Treat the stated intent as a proposal to review, not proof the agent understood. Do not imply certification or formal assurance.
Source-lineage note
This skill is an original software-workflow translation of stating intent before acting. The "I intend to" construct and leader-leader idea are concept inspiration from intent-based leadership only — paraphrased, not template lineage (a copyrighted source; see docs/00-standards-foundation/do-not-cite-directly.md). Its public idea lineage is the deliberate-action, self-checking, and three-way-communication habits in DOE-HDBK-1028-2009, mapped in docs/00-standards-foundation/source-map.md. It does not create DOE compliance, formal assurance, safety, security, certification, or regulatory adequacy.
