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 | $0.41532 | $0.41532 |
| Opus 5 | $0.20766 | $0.20766 |
| Sonnet 5 | $0.08306 | $0.08306 |
| Haiku 4.5 | $0.04153 | $0.04153 |
Grade A, and why
Yodecomp CLAUDE.md 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 2d 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 — 1,669 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Yodecomp — Desktop Adventures decompilation + engine
Decompilation of LucasArts' Desktop Adventures engine (Yoda Stories / Indiana Jones' Desktop Adventures)
into real, buildable C++/MFC source, plus an extended multi-game engine built on it. Patterns follow
~/workspace/OpenJKDF2 (CMake, macOS/Linux hosts, wine for Windows toolchains). Claude is permitted to
modify this file with any useful notes that will aid other/later Claudes.
Deep history lives in PLAN_COMPLETED.md — the full phased plan (A–G), TU/struct status tables, the
v1–v71 milestone chain, and the ⭐ KEY codegen lessons #1–#40 + MFC-matching lessons (later lessons #41–#47 are standing bullets in this file) (cite as
"PLAN_COMPLETED.md lesson #N"). This file carries only what's needed to work NOW.
Where the project stands (2026-07-11, v87; re-baselined 217→234 at v100 (MEASUREMENT FIX); 234→237 at v102, 237→240 at v103, 240→244 at v104, 244→247 at v105, 247→249 at v106, 249→250 at v107, 250→251 at v108, 251→255 at v110 (REAL MATCHES); 255→252 at v114 — a DELIBERATE, user-approved re-baseline DOWN, see below; held at 252 at v115; 252→255 at v116 (REAL MATCHES — the CONTAINER CALL FORM, lesson #48); held at 255 at v117, which landed no new match but cut 654 bytes of residual STRUCTURALLY via the new LENGTH census, lesson #49; 255→257 at v118 (REAL MATCHES — the MEMBER-ALIAS/CSE-reload dial, lesson #50, plus the INNER-BLOCK decl axis no tool could reach); 257→258 at v119 (REAL MATCH — the COMPOSITE LEVER, lesson #51: two dials that each measure WORSE alone, including on LENGTH, landing together; it also cut 1029 bytes of residual across four more functions and put four more LENGTHS exactly on their Ghidra extents); 258→255 at v120 — the SECOND DELIBERATE, user-approved re-baseline DOWN, for a real ARITY BUG in TextDialog::Layout, see below; v120 also cut 1050 bytes of residual across three functions and put two more LENGTHS exactly on their extents; 255→256 at v121 (REAL MATCH — the CROSS-JUMPED IF/ELSE, lesson #52: a constant argument materialized by a BRANCH in the original is two duplicated CALLS tail-merged, not an expression); held at 256 at v122 — no new byte-match, but OnNewDocument 0x41bb10's LENGTH went 946 -> 975 = its extent EXACTLY (537 B -> 422) on a RECOVERED MISSING SOURCE CONSTRUCT, the house CATCH_ALL+THROW_LAST, found by lesson #53's read-it-out-of-your-own-exact-code method; held at 256 at v123 — no new byte-match, but the SIX closest-to-exact functions in the project (11 bytes total) were PROVEN unreachable from the source and closed: lesson #54, the compare-encoding peephole)
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.

Yodecomp CLAUDE.md is an instructions file published in the GitHub repository shinyquagsire23/Yodecomp (22 stars, last pushed 3d ago), licensed CC0-1.0. It adds 41,532 tokens to every session, about $0.2077 per session on Opus 5. A static security scan graded it A with 0 findings.
