signal-integrity-review

signal-integrity-review is a skill for Claude Code, Codex from fireostendere/mcp_diptrace. It costs 48 tokens per session (888 once invoked), scanned A, original, Apache-2.0.

A review workflow for checking PCB signal quality, including trace shape, board layers, return paths, and available simulation evidence.

In plain words
What is it for?
Use it to review impedance and return paths on single-ended or differential traces, and to report when a requested analysis is unavailable.
Why use it?
It separates estimates from external simulations and prevents pass/fail claims when required board details or tools are missing.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

signal-integrity-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Signal-integrity review

Keep analytical equations, geometry heuristics, and external solver output in separate evidence classes. No result is fabrication sign-off. Use public tools/list for exact callable names and get_capabilities for document/configured feature and adapter availability.

Scope selection

  • microstrip: supported single-ended analytical model for an outer-layer trace.
  • differential_microstrip: supported coupled analytical model with explicit gap.
  • symmetric_stripline: supported single-ended analytical estimate within its published range.
  • Differential stripline: unavailable; return blocked_by_capability.
  • run_openems_stripline_analysis: a registered typed external adapter, not a bundled solver.
  • run_ngspice_simulation: a registered batch adapter for a caller-supplied netlist, not a PCB geometry extractor.

Workflow

  1. Call diptrace_status, get_capabilities, and get_document_info; freeze the PCB SHA-256.
  2. Read get_stackup and get_route_details. Require explicit net, layer, dielectric height/permittivity, copper width/thickness, reference conductor, and target/tolerance when a pass/fail judgment is requested.
  3. Use calculate_impedance for standalone inputs, analyze_stackup_for_impedance for complete outer-layer microstrip stackups, and validate_impedance_constraints or analyze_controlled_impedance for named routed nets.
  4. Use analyze_return_path only as a caller-radius geometry heuristic. Disclose boundary-only pour geometry, layer-transition ambiguity, and confidence limits.
  5. Invoke ngspice/openEMS only when runtime discovery says the configured adapter is available. For openEMS retain request SHA-256, solver version, convergence, result SHA-256, and resources. For ngspice retain the netlist SHA-256, job status, return code/log summary, and resources; its current API exposes no executable version, convergence field, or result SHA-256, so record those fields as unavailable instead of inventing them.
  6. Emit ../shared/result.schema.json. Put impedance, effective permittivity, length/skew, frequency, and return-path coverage values in measurements, each with a unit, evidence class, and evidence IDs; do not hide numeric evidence in prose.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

signal-integrity-review is a skill published in the GitHub repository fireostendere/mcp_diptrace (22 stars, last pushed 2d ago), licensed Apache-2.0. It adds 48 tokens to every session and 888 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
