What is th08-library?

A workflow for recovering runtime and D3DX library functions linked into the original Japanese TH08 1.00d executable. D3DX is part of Microsoft's older DirectX graphics-support libraries.

Use it to inventory target-linked library functions, identify their original library sources, pin evidence with SHA-256 hashes, compare relocated code, and prepare complete linking. It does not cover the separate Detours submodule.

Library code inside a game executable must be matched to the correct toolchain, archive member, and binary location; this workflow adds provenance, hashing, and boundary checks.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00062	$0.00751
Opus 5.5	$0.00025	$0.00300

Security

Grade A, and why

th08-library 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.

TH08 target-linked library recovery

This skill covers type=library rows inside the original Japanese TH08 1.00d image. It does not cover 3rdparty/Detours, which only supports the optional reconstruction DLL.

Preflight

Read AGENTS.md, docs/RE_HANDOFF.md, docs/RE_WORKFLOW.md, and docs/TOOLS.md.

Run:

python3 scripts/verify-target.py
python3 scripts/validate-tracking.py --require-target
python3 scripts/analysis/report-reconstruction-status.py \
  --category library --state missing-size --sort address

The current first-lane result is seven rows. If that count changes, trust the command and current ledgers rather than copying an old prose list.

Select one coherent runtime/D3DX family. Reconcile every start and extent against target control flow before editing mapping.csv; imported Ghidra boundaries and the next CSV address are leads, not accepted sizes.

Evidence gates

Identify the exact originating toolchain/library version and archive member. Record SHA-256 for each archive used as evidence. A same-name TH07 archive or a modern SDK library is not a substitute.
Keep target facts, archive/member facts, inferred symbol names, and unknown boundaries distinct.
Compare code only after replaying COFF relocations and accounting for archive member padding, COMDATs, jump tables, thunks, and linker-owned transformations.
Prefer compiler/library source or extracted COFF evidence. Never recreate CRT or D3DX bodies with inline assembly, byte arrays, empty stubs, or copied target bytes.

Ledger boundary

No library exact ledger exists yet. config/implemented.csv, config/matches.csv, and docs/PROGRESS.md currently describe authored work; do not repurpose them for library percentages.

Before the first library acceptance, propose and review:

an archive-provenance manifest with hashes and member identities;
a library match-unit schema with target address, accepted extent, object or archive member, relocation replay, and evidence command;
validation that works without private target bytes in public CI and a local target-required acceptance command;
a separate library progress view that does not change authored totals.

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-library is a skill published in the GitHub repository N0zoM1z0/th08 (55 stars, last pushed yesterday), licensed MIT. It adds 62 tokens to every session and 751 once invoked, about $0.0002 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.
