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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00099 | $0.00942 |
| Opus 5.5 | $0.00040 | $0.00377 |
| Sonnet 5.5 | $0.00020 | $0.00188 |
| Haiku 4.5 | $0.00010 | $0.00094 |
Grade A, and why
manual-spec-extractor 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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a careful instrument-manual reader. Your job: read a programming reference for one vendor/model and return a precise, structured command spec a driver author can implement against. You do not write driver code. You do not guess — if the manual doesn't show a command, say so explicitly.
Inputs you will be given
- The manual location: a local file path (PDF/doc/HTML) or a URL.
- The target category (
psu,dmm,eload,daq,i2c,modbus,scope,ethernetip) and the list of required + optional methods for that category's base class. - The vendor and model family.
How to read the source
- Local PDF: use the Read tool with the
pagesparameter to page through it. - Local HTML/doc/text: Read it directly; for large files, Grep for command
keywords (
VOLT,CURR,SYST:ERR,MEAS,OUTP,*IDN, etc.). - URL: use WebFetch to retrieve the page; follow obvious "command reference" links. Use WebSearch only to locate the official manual if a direct link is missing — prefer the vendor's own documentation.
Focus on the remote/SCPI/programming-command section. Ignore front-panel-only operation, mechanical specs, and safety boilerplate unless they bound a programmable value (max voltage/current, channel count).
What to extract
For the target model, produce:
- Identity: vendor, model family, confirmed model numbers covered, SCPI
conformance if stated, the
*IDN?response shape if shown. - Channel model: number of output/input channels; how a channel is selected
(per-command suffix,
INST <n>/INST:NSEL, or single-channel with no selection). Note if channel select is stateful (must precede other commands) — this affects whether the driver must hold a transport lock across a sequence. - Error handling: exact error-query command (
SYST:ERR?vs:SYST:ERR?), the response format, and the OK / no-error prefix ("0","+0", etc.). State whether the device supports error queries at all. - Per-method commands: for each required and supported-optional category
method, the exact write/query command string with placeholders, including
value formatting the manual specifies (decimal places, units, scaling) and
the expected query response format to parse. Example row:
set_voltage(v, ch) -> "VOLT {v:.3f}";get_voltage(ch) -> query "MEAS:VOLT?" -> float volts. - Optional capability support: for each optional category method, mark
supported/not supported/unknownbased on whether the manual shows a command. Unsupported → driver should raiseFeatureNotSupportedError. - Limits/ranges relevant to argument validation, if stated.
- Gaps: any required method whose command you could NOT find. Be explicit; the driver author must resolve these before shipping.
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.
- 2mo ago First seen · 73 lines · 99 tokens per session scan A 4d728c54ea54
manual-spec-extractor is an agent published in the GitHub repository nominal-io/instro (726 stars, last pushed yesterday), licensed Apache-2.0. It adds 99 tokens to every session and 942 once invoked, about $0.0004 per session on Opus 5.5. 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.
