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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00062 | $0.07431 |
| Opus 5 | $0.00031 | $0.03716 |
| Sonnet 5 | $0.00012 | $0.01486 |
| Haiku 4.5 | $0.00006 | $0.00743 |
Grade A, and why
th08-matching 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 10d 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 — 379 lines — stays where its author put it; the contents beside it link to each section on GitHub.
TH08 exact matching
Use with $th08-re only after the target boundary, semantics, and ABI are
supported by evidence.
Canonical loop
-
Verify the target and list configured units:
python3 scripts/verify-target.py python3 scripts/compare-function.py --list -
Read the selected
[[units]]entry inconfig/match-units.toml. Confirm its target address/size, decorated COFF symbol, object path, and every relocation againstconfig/mapping.csv,config/reccmp-*.csv, and target disassembly. If an original delinked object is required and Ghidra is configured, generate it through the verified disposable import:python3 scripts/export_ghidra_objs.py --import-csv -
Build the entry's object basename. For an object recorded as
build/ScreenEffect.obj, run:python3 scripts/build.py --build-type=objdiffbuild --object-name ScreenEffect.objIf VC7 emits the right implicit constructor bytes but omits a COFF function- definition auxiliary record, declare and define the natural empty constructor explicitly, rebuild, and compare again. Do not synthesize behavior; member construction must remain compiler-driven.
-
Compare the configured function:
python3 scripts/compare-function.py UNIT --json -
Treat
exact,mismatch, anderrorliterally. Classify a mismatch before editing source: function boundary, ABI/layout, compiler flags, decorated symbol, REL32/DIR32 mapping, source/control-flow order, or translation-unit effect. -
Change one source-plausible expression or declaration, rebuild the same object, and rerun the same unit.
For a read-only search of already built, source-emitted leaves, use the conservative discovery gate:
nice -n 15 python3 scripts/analysis/propose-exact-units.py --min-size 0x80
It emits review-only candidates only when the target-pinned isolated extent,
full relocation replay, direct-call multiset, named destination ledgers, and
unique object ownership agree. --allow-unimplemented may reveal source-built
functions missing from implemented.csv; it never updates tracking. Inspect
the source and target, add a reviewed unit, and obtain this skill's canonical
compare-function.py exact result before entering either ledger.
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.
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.

th08-matching is a skill published in the GitHub repository N0zoM1z0/th08 (162 stars, last pushed 4d ago), licensed MIT. It adds 62 tokens to every session and 7,431 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.
