analog-spec-extract

analog-spec-extract is a skill for Claude Code from vibeic/vibe-ic. It costs 55 tokens per session (1,976 once invoked), scanned A, original, Apache-2.0.

A skill that reads analog design documents and creates a machine-readable specification for each analog circuit block. Analog blocks are circuit sections such as oscillators, voltage regulators, bandgaps, or charge pumps that need transistor-level design.

In plain words
What is it for?
Use it at the start of an analog design project to identify required blocks from L1 and L5 documents and produce a spec.json file for each block.
Why use it?
It turns scattered requirements and interface details into an explicit list of design units. This helps prevent circuit requirements from being silently omitted.

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

analog-spec-extract 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.

The scan reads SKILL.md. This mod also ships 1 executable file (tests/test_compliance.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Analog Spec Extract

Reads L1_DATASHEET.json (pin types, electrical specs) and L5_ADI_SPEC.json (analog-digital interface) to enumerate every analog block that needs transistor-level design, and produces a machine-readable spec.json for each.

⛔ HARD RULE — never silently emit empty block list (Wave 47, v0.120.1)

User directive (Wave 47): "EVERY ITEM IN DESIGN DOCUMENTS SHOULD BE IMPLEMENTED!!!! EVERY!!!"

The deterministic parts of this hard rule are now programs — run them, don't re-implement them in prose:

  • 8-class analog keyword scan + L5-mapping — enforced by programs/analog_content_detected_must_emit_l5_check.py (the chip-AGNOSTIC grep over input_doc/*.txt + input/docs/*.txt for oscillator / ldo / bandgap / por / pull / esd / charge_pump / trim, with per-hit negation awareness, lives there). For each detected class emit at least one minimal analog_blocks[] entry:
    {"name": "<descriptive>", "type": "<class>", "spec": "<one-line>",
     "evidence": "<file>:<line>", "implementation_status": "needs_design_work"}
    
    then run the gate against <project_dir>.
  • Forbidden analog/A0_skip_decision.json top-level skip — enforced by programs/analog_a0_skip_forbidden_check.py. Replace any skip with analog/A0_implementation_status.json (per-block A1-A8 status) OR set L5.analog_blocks_detected=false when the keyword scan PASSes empty.

A1 (this skill) PASS criterion is keyword-grep cleanliness, not human judgment that "the chip looks digital".

Residual LLM judgment (not a program): the keyword scan is a recall floor, not a complete detector — recognising a NON-keyword analog block (a custom sensor-readout front-end described only functionally, with no token in the 8-class list) is exactly where your judgment is needed. Catch what the grep misses and add it to analog_blocks[] anyway.

Spurious-block flip-side (cross-ref → analog-topology-select, #466B): the recall floor also OVER-fires. A candidate emitted only because a product-name keyword in L1 matched a class — with no spec ever bound (spec == null) — is presumed spurious and must be confirmed against the L5 type enumeration (the "N analog blocks" count sentence and/or the Block A/B table headers) before A2 spends any sizing compute. Drop it if L5 doesn't enumerate that class; keep + spec-bind it if L5 does. A block's multiplicity (×N) must come from the block's OWN enumeration row, never a sibling block's evidence paragraph. The full sanity procedure + why_not_bucket_a rationale lives in analog-topology-select's "spurious-block sanity check" capture; do not re-implement it here as a deny-list — whether a name-only block is real requires reading L5, not a static rule.

What this file has done since we first saw it

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.

analog-spec-extract is a skill published in the GitHub repository vibeic/vibe-ic (23 stars, last pushed today), licensed Apache-2.0. It adds 55 tokens to every session and 1,976 once invoked, about $0.0003 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.
