Electronics AI agent · Spec and compatibility
Spec & Compatibility AI Agent
Answer parameter and compatibility questions from the datasheet revision on file, cite that revision on the face of the answer, and hold it for the named applications engineer, who decides what is said.

What this agent does
Cites the document; it does not certify the part
In
- 01
Where an enquiry names a part, pull the vendor datasheet, errata and matrices from the authorised sources on file.
- 02
When a part number arrives partial or fuzzy, stop and resolve the full orderable suffix before anything else runs.
Reason
- 03
Where a parameter is quoted, carry its min, typ or max designation and the test conditions printed beside it.
- 04
When a datasheet has been superseded, read the errata or specification update over it and cite both.
- 05
Where a lifecycle notice is on file, surface the PDN with its last-order and last-ship dates as JESD48C states them.
Decide
- 06
When a certification mark is claimed, check the certifying body's own list and say plainly if it was not verified.
- 07
Where a specification version is cited, list the features the document itself says the product supports.
Out
- 08
Retain the question, the documents read, their revision identifiers, the retrieval dates and the engineer's release.
- 09
Execute write actions only inside the approval boundaries agreed during implementation.
Product statement
The agent cites; the applications engineer of record decides what leaves the building, and the seller warrants what is said.
Example workflow
One enquiry, question to release
- 1Enquiry receivedSales question, design-in query, distributor request or ticket
- 2Documents retrievedDatasheet revisions, errata and lifecycle notices, each with its revision identifier
- 3Citations assembledCited values, the comparison, unresolved points and confidence
- 4Controls appliedSuffix resolution, revision-currency checks, certification checks and confidence threshold
No human action required
Stages 1 to 4 run unaided, and nothing is asserted at any of them — the agent is citing, and the engineer's lane opens at the confidence gate.
Goes to the applications engineer to release.
Refuses and asks for the document.
Engineering release
The answer is held with its citations, its unresolved points and the confidence.
Release · Amend · Send to engineering lead
Released — answer goes out
- 6CRM and support systems updatedOnly where write access and approval policy allow it
- 7Outcome evaluatedCitation accuracy, revision currency, engineer amendments and post-release corrections
Amendments
Every amendment is counted in the evaluation.
What should not run autonomously
Human approval stays in control
Outside the boundary — human approval required
8 items
- Confirming a part will work in your design.
- Recommending a part for a customer's application.
- Asserting a USB-IF, HDMI, Qi2, Matter or Thread mark.
- Reading a feature out of a specification version number.
Automation boundary
Agent acts unaided
- ✓Resolve the full orderable part number, suffix included for the named owner.
- ✓Cite each value with the revision it was read from.
- ✓Surface errata and any lifecycle notice on file.
- ✓Assemble a side-by-side comparison and hold it for the engineer.
Any write happens inside the boundaries agreed at implementation, never ahead of the engineer's release.
- Answering where no current revision is on file.
- Approving a cross-reference or a suffix substitution.
- Releasing technical data beyond the published datasheet.
- Changes to the citation rules or the approved source list.
Example output
One compatibility answer, annotated
Everything the agent cites is attached to the revision it was read from.

Why it reads this way
It is a rated maximum, not a typical value — the line the engineer weighs.
What the score decides
Below the configured threshold the answer picks up an engineering-lead read before release.

Where AI adds value
The same four claims, placed at the point in the workflow where each one applies.
Where the value lands
Value 01 – 04
Every enquiry
From the documents on file
Answer from the revision
Draw on the datasheet revision, its errata and the lifecycle notices held for that part.
Cite the revision, not the memory
Routine parameter questions come back already cited and dated.
Put the unsupported answers first
Superseded documents, missing revisions and unverified marks are flagged, so the engineer reads where warranties attach.
Build an evidence trail
The answer, the datasheet revision behind it and the engineer who released it stay attached.
Integrations
Typical integrations
Five system groups connect to the same agent. Which of them are in scope is decided in discovery.

Agent controls
Six layers between the model and the answer
Every layer wraps the next. What none of them catches is in the map below.
L6 · Outermost — last line of defence
Inward → L1 · closest to the model
- L1 – L2
- Test whether an answer may stand
- L3
- Puts the release in an engineer's hands
- L4 – L5
- Hold the document revision the answer rested on
- L6
- Falls back to document lookup when signals degrade
How Nestack evaluates it
Evaluate the whole retrieval path — not only the sentence at the end.
Coverage runs the whole depth of the workflow, and every layer is cut by slice.
Surface — the answer the customer reads
- E1Final-output evaluationDid every cited value match the revision it was attributed to?
- E2Step-level evaluationDid the agent read the current revision, its errata and its notices?
- E3Tool evaluationDid it resolve the correct part number and read the correct table?
- E4Confidence calibrationDo low-confidence answers actually attract more engineer amendments?
- E5Slice evaluationHow does performance change across specific product families?
- E6Business outcomeHow many released answers needed a correction after they went out?
Floor — the answer the seller warrants
Failure modes
Where each failure originates in the agent
Seven modes, set at the stage each one starts in.
Agent lifecycle
Direction of processing →
01 · Retrieval
1 mode
- XR-03
Superseded revision
A value is read from a revision the vendor has since replaced.
Stage gathers
Datasheet revisions, errata, notices and matrices
02 · Reasoning
2 modes
- XR-04
Version read as feature set
A specification version number is taken to mean a supported feature.
- XR-06
Typical read as guaranteed
A typical parameter is treated as a limit and headroom is asserted.
Stage proposes
Cited values, the comparison and confidence
03 · Tool / write
2 modes
- XR-02
Certification asserted
A mark is stated for a product not on the certifying body's list.
- XR-05
Suffix normalised away
A truncated suffix answers about a different grade or package.
Stage writes
Only where write access and approval policy allow it
04 · Output
1 mode
- XR-01
Lifecycle notice missed
A part under an active PDN is answered as though it were current.
Stage returns
The answer the engineer releases and the buyer reads
05 · Change / Version
1 mode
- XR-07
Errata source dropped
An index refresh drops the errata source and answers regress.
Stage tracks
Model, prompt, source catalogue and citation rules
- Sev-1 · a held act performed by the agent
- Sev-2 · a wrong value reaches the customer
- Sev-3 · a source degrades, answer goes to review
Affected slices
Overall accuracy can hide one family
Do not read the aggregate citation figure on its own — break it out by cohort. Nestack reports the rate by slice, because a few part families absorb most of the wrong answers.
Slice performance — reported separately, not only in aggregate
Illustrative example| Slice | Failure rate | Lift | Lift vs. threshold | Status |
|---|---|---|---|---|
| Parts under an active PDN | 6.5% | 3.8× | Review | |
| Suffix variants of one base part | 4.4% | 2.6× | Review | |
| Optional-feature standards | 3.2% | 1.9× | Watch | |
| Mature parts, one revision | 1.2% | 0.7× | Normal |
Bar: wrong-citation lift vs. the mature-part baseline · scale 0–4.0× · tick marks the 2.0× review threshold

Evidence-linked improvement
A cycle ends in the suite, not a meeting
The loop shuts when the miss is a case in the suite, not when it has been explained. That suite is what the next compatibility answer is measured against.
Improvement cycle · five stages
Switchback — the path turns at Improve and returns at Learn
- 01
Detect
Wrong-citation rate rises in a part family.
- 02
Diagnose
Read the released answers back against the revisions they cited, until one document, rule or prompt accounts for it.
- 03
Improve
Whatever changes ships against a version, with the answers that prompted it attached.
- 04
Verify
Nothing ships until the affected cases pass a second time.
- 05
Learn
The suite grows by one case; so does the citation rule set.
Learn → Detect
The return edge. The next detection runs against a longer suite than this one.
Typical build scope
Twelve workstreams across six weeks
The build scope read against the delivery timeline. Week structure follows the six-week plan — discovery, sources, citation workflow, evaluation, integration, then production validation and handover.
