datasheet-and-refmanual-reading

datasheet-and-refmanual-reading is a skill for Codex from OutlineDriven/outline-driven-development. It costs 48 tokens per session (1,228 once invoked), scanned A, original, Apache-2.0.

A guide to finding technical facts in microcontroller datasheets, reference manuals, and errata sheets. It extracts pin assignments, electrical limits, registers, clocks, timing values, and documented hardware problems.

In plain words
What is it for?
Use it to confirm register fields, pinouts, clock limits, timing requirements, electrical conditions, and peripheral behaviour for an exact part.
Why use it?
It prevents driver and hardware decisions based on guesses or on values that apply only to a different chip revision, voltage, or operating mode.

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

datasheet-and-refmanual-reading 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 3d 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.

Datasheet and reference manual reading

Contract

Field Bound contract
Trigger Driver work starts on unfamiliar silicon, a register bit behaves ambiguously, an electrical or timing limit must be confirmed, or the question is where in the documentation a fact lives.
Authority Read-only: reads vendor documents and reports locations, extracted values, and cross-references to chat. Rollback is not needed because no file is written. No remote mutation.
Side effect Chat output only.
Done Each requested fact is reported with the document, section, and table it came from, its conditions (voltage range, silicon revision, mode) are stated, and the errata sheet has been checked for the peripheral.

Inputs

  • The exact part number, including package and revision suffix, and the silicon revision if known (DBGMCU->IDCODE REV_ID on STM32).
  • The vendor documents: datasheet, reference manual, core programming manual, and errata sheet.
  • The question: a pin, a register field, a clock limit, a timing parameter, or a peripheral behavior.

Procedure

  1. Pick the document by the kind of fact. Done when: the fact is being sought in the document that owns it.

    Document Owns
    Datasheet Pinout and alternate-function table, absolute maximum ratings, operating conditions, package, electrical and timing characteristics
    Reference manual Memory map, register maps and bit fields, clock tree, peripheral behavior and init sequences
    Core programming manual (Arm) Core registers, NVIC, SysTick, MPU, fault registers, debug
    Errata sheet Silicon defects and the firmware workaround for each

    The datasheet says what exists; the reference manual says how to program it.

  2. Read the reference manual in this order on a first pass: memory and bus architecture, reset and clock control, GPIO and pin multiplexing, the target peripheral chapter, the interrupt and event mapping table, then electrical characteristics only when timing is critical. Done when: the base address, clock enable bit, pin mux, and interrupt line for the peripheral are each located.

  3. Extract each register with its full row, not just the bit name. Done when: every column below is filled for each register the driver will touch.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

datasheet-and-refmanual-reading is a skill published in the GitHub repository OutlineDriven/outline-driven-development (52 stars, last pushed 3d ago), licensed Apache-2.0. It adds 48 tokens to every session and 1,228 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 2026-09-06.
