HCAI / Engineering-Handoff Profile
Evidence before engineering commitment.
Start with the work people do today. Decide what evidence justifies building the next step.
A risk-tiered review of the current workflow, end-user requirements, recovery paths, traceability and human oversight costs. The result supports a bounded engineering decision.
A missing answer stops the review.
Use existing records for one low-risk workflow. These are mandatory gates, not a score. Six prompts can support a useful decision even when the right result is to stop and gather evidence.
- Can we quantify today's work? Capture the current path and people, cycle and labor time, touches, failures, review, rework and volume. No measured baseline means insufficient evidence and indeterminate ROI.
- Whose need does the change address? State the outcome and connect it to owned requirements with measurable acceptance criteria.
- What happens at the edges? Define normal, edge and recovery paths, data preservation, dependencies and responsibility.
- Can we trace the behavior? Connect each important artifact to its requirement, form/fit/function references and an executed walkthrough or test.
- Who checks and corrects AI output? Estimate review, correction, escalation, rework and remaining manual effort before trusting gross savings.
- What engineering step is justified? Apply risk depth, resolve blocking findings, and record a resource ceiling, owner and next review trigger.
Stop at the first unmet gate.
Record the missing evidence and next action. Later gates are marked not evaluated. Continue with a new full-profile run after remediation. A strong score elsewhere cannot rescue a failed gate.
Download the advisor sheetInsufficient evidence. ROI indeterminate.
Next action: observe the current workflow.
Five layers. Separate evidence.
Evaluation cost, projected operating oversight and actual system performance stay separate. There is no combined readiness score.
- ACurrent-state baseline
- Observed time, people, handoffs, errors, review, escalation, rework and volume. Compare proposed work with a measurable starting point.
- BProposed workflow
- End-user needs, requirements, states, edge cases, recovery, owners, acceptance criteria and dependencies.
- CEvaluation and oversight burden
- Record the time and cost of running this protocol. Separately estimate the human review and correction burden of operating the proposed workflow.
- DEngineering-handoff evidence
- Trace requirements to artifacts and validation. Retain reference defects, reviewer findings, unresolved risks and the bounded decision record.
- EOperational system performance
- Measure after implementation in realistic use. Documentation and upstream gate results do not establish this layer.
Net time saved = gross time saved − review − correction − escalation − rework. Report remaining manual work, recurring costs and one-time implementation cost. Keep protocol evaluation cost separate. Missing baseline means ROI is indeterminate.
Let the consequences set the evidence burden.
The highest rating across complexity, importance, impact, mission, failure consequence and irreversibility determines the tier. Unknown risk prevents a qualifying pass.
QUICK-6 or full
At least one observed baseline case and one need-source record, with every core gate passed. The quick review must finish within 15 minutes.
Full profile
At least three baseline cases, two need sources, actual end-user discussion, independent review and a validation plan.
Deeper full review
At least five baseline cases and all moderate-tier evidence, plus hazard analysis, mission review and an operational evaluation plan.
These are provisional minimum evidence floors, not validated safety thresholds or statistically representative sample sizes. The full profile may require more evidence for the actual context.
Inspect a traceability example
Illustrative requirement: an advisor can cancel an incomplete intake request without losing entered details.
- Reference
- Current workflow, saved-field specification and user need.
- Form / fit / function
- An editable review form; it fits the advisor's intake process; correction and cancellation preserve the specified fields.
- Artifact → validation
- Versioned review and recovery states → a recorded walkthrough against the requirement's acceptance criteria.
- Decision boundary
- A walkthrough may support engineering commitment. It does not prove an implemented system works in operation.
Move the evidence check earlier.
- Requirements first: make the intended workflow testable before committing engineering resources; separate the later deployment decision.
- Current state before ROI: require a measured baseline and include the human effort created by AI output.
- Traceability beyond appearance: Hillel Glazer's feedback emphasized requirements, validating tests and reference material for form, fit and function. Attribution is approved; no endorsement is implied.
- A usable short path: provide advisor-led QUICK-6, visible stops and risk-based escalation.
- Actual use as the next evidence stage: collect a bounded end-user/advisor session with permission, time, gate outcomes and feedback. Keep private correspondence private.
Other feedback themes are reflected in these design changes without publishing private identities or comments. Correspondence, meeting invitations and software tests are distinct from controlled empirical validation.

Every download below is labeled 0.1-rc.4-candidate. Pilot participation is voluntary; no organization is represented as sponsoring or requiring it.
QUICK-6
Six prompts, evidence expectations and stop rules.
Candidate protocol
Decision logic, five layers, costs and limitations.
Full profile
Evidence requirements for moderate and high risk.
Short pilot packet
One workflow, permission choices and a capture form.
Complete candidate
Method, schemas, tools, synthetic fixtures and checksums.
Verification record
Implementation test results; no claim of empirical effectiveness.
Actual external pilot records are currently empty. Promotion to final rc.4 requires passing regression checks and recorded bounded external use reviewed by the author.
One decision logic across both tools.
MCP 0.2.0rc1 and ai-ready Skill 0.2.0-rc.1 use the same deterministic gates and contracts. Prompts help gather and interpret evidence; they do not override a stop.
MCP: validate and calculate
Use completed evidence records to check the six gates and report separate costs, oversight estimates and provenance. The server runs locally and uses no model key.
Candidate MCP configuration
Requires uv. The first run downloads the versioned candidate wheel and dependencies from this site and the package registry. Your assistant host can see supplied data.

ai-ready: guide the review
Collect the baseline, choose risk depth and guide an advisor through the evidence. Its bundled Python engine also runs without MCP. Python 3.11+ and Pydantic 2 are required for deterministic execution.
Download candidate SkillExtract the ai-ready folder into your assistant's Skill directory. Follow the included method and requirements. Without a runtime, the Skill prepares evidence and reports assessment pending.
Installation and migration detailsEvery run records protocol, MCP, Skill and contract versions plus evidence digests. Agent reviews remain separate from human observations. A qualifying recommendation still requires the owner's recorded engineering authorization.
rc.3 remains available.
The original method, worked example, workbooks and software history are preserved. These older materials do not implement the candidate baseline and risk gates.
