What it does
Lilly Community Research is an agent skill from ssaaffaakk/Lilly. Lilly community-research skill. Community-sourced (Reddit) fixes, tools and failure-mode warnings for Lilly's four components: Whisper ASR (Croatian drift, KenLM rescoring, low-resource fine-tuning), MarianMT translation (chrF2 plateau, BCS lexicon drift, glossary/constrained decoding), OCR (invented words, Cyrillic blindness, diacritics, synthetic-to-real gap) and Piper TTS (voice ceiling, phonemizer/espeak problems). Use when working on any of those four components, or when the user mentions Croatian drift…
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `references/ocr.md`, `references/sources.md` and `references/speech-asr.md`).
It sits in AI & LLM Engineering, covering Speech recognition and synthesis, Text to speech and voice and Translation. It works with Reddit, Kaggle and FastAPI. The repository describes itself as: Bosnian-first offline assistant: type, speak, and snap street text → English. FastAPI app + Kaggle-trained listen/read models. Fail-stop training. The licence is MIT.
When your agent uses it
- Working on any of those four components
- The user mentions Croatian drift
- Invented OCR words
- KenLM rescoring
Example prompts
- “community tips”
- “/lilly-community-research”
What it can do on your machine
Read from SKILL.md and the folder at commit 4ebfde6. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Lilly Community Research loads about 1.4k tokens when it runs, and up to ~9.7k if it reads all its reference files. Until then it costs about 226 tokens; SKILL.md has 570 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Lilly community-research skill. Community-sourced (Reddit) fixes, tools and failure-mode warnings for Lilly's four components: Whisper ASR (Croatian drift, KenLM rescoring, low-resource fine-tuning), MarianMT translation (chrF2 plateau, BCS lexicon drift, glossary/constrained decoding), OCR (invented words, Cyrillic blindness, diacritics, synthetic-to-real gap) and Piper TTS (voice ceiling, phonemizer/espeak problems). Use when working on any of those four components, or when the user mentions Croatian drift, invented OCR words, Cyrillic OCR, diacritics, rs_cyrillic, KenLM rescoring, whisper speech improvement, language-token mislabelling, low-resource NMT, backtranslation, glossary injection, constrained decoding, chrF not moving, Piper voice quality, TTS espeak phonemes, or "community tips". Provides concrete, measured-mistake-mapped techniques with Reddit sources.
Lilly Community Research — community-sourced fixes, mapped to our measured mistakes
A permanent index of Reddit-sourced techniques for Lilly's four components. Built
13 Sep 2026 from a deep Reddit research pass. Each reference maps every technique to
the measured failure it fixes, and each has its provenance in references/sources.md.
GATE RULE — read first. This skill is advice, not a verdict. No technique in here ships, changes a pre-registered number, or becomes a new baseline unless it runs the same pre-registered gate as any other arm:
PREREGISTRATION.md, score throughapp.translate.Engine/app.ocr.scan, on the held-out rulers, never past a metric you carved for it. The proper shape of every idea here is: new arm intraining/PREREGISTRATION.md, run it, write RESULTS, then judge. If a technique below contradicts a result file already in the repo, the result file wins until a new arm beats it at a gate.
When to use
- Working on any of: speech listener (Whisper), translation (Marian/opus-mt, en↔bs), camera reader (OCR), or TTS voice (Piper).
- User mentions: Croatian drift, invented OCR words, Cyrillic, diacritics, KenLM, language-token mislabelling, chrF plateau, glossary/constrained decoding, espeak, WER not improving, "community tips", "what does the community do".
When NOT to use
- Nothing here replaces
docs/*(what-moves-the-model, diacritic-gate-literature, OCR-ROADMAP, HANDOFF.md). The repo docs are the settled record; this skill is the un-assessed idea shelf. - If a technique contradicts a repo result file, the result file wins (see gate rule).
- Do not cite a Reddit thread as proof for a claim about Lilly's own numbers. Threads are evidence that someone tried the technique; our numbers decide if it works here.

Known mistake → candidate fix map (the whole shelf at a glance)
| Component | Measured mistake / number | Candidate fix (details in reference) |
|---|---|---|
| Speech | Croatian substitution 1.1%→6.1%, large-v3 | KenLM/Ijekavian n-gram rescoring — no retrain |
| Speech | Croatian spelling via decode (vreme/dete) | initial_prompt + suppress_tokens on Croatian forms |
| Speech | <bs> token in front of Croatian text (root cause) | Force language=bs + task=transcribe per segment |
| Speech | drift cascades window→window | condition_on_previous_text=False + VAD gate |
| Speech | small-data fine-tune regressed WER | 1000–3000 steps, checkpoint-per-bucket eval, bs holdout |
| Speech | decoder picked up hr prior (11h bs vs 91h hr) | freeze encoder / tune only decoder (Distil-Whisper lesson) |
| Speech | appended hr data hurt old perf | one consolidated pass, bs upweighted, bs holdout stops |
| Translation | fine-tune does not move chrF2 (−0.16 tie) | data must be genuinely out-of-corpus; re-check overlap |
| Translation | Croatian lexicon losses (vlak/voz, travnja/aprila…) | glossary injection + constrained decoding at inference |
| Translation | Croatian-lexicon drift is "dictionary not GPU" | zero-training decode bias against hr pairs (lever #2) |
| OCR | 450 invented words at floor 0.9 | word-level gating + two-engine agreement + charset whitelist |
| OCR | Cyrillic unreadable (272/1,702 crops) | route crops to rs_cyrillic / cyrillic_g2, then transliterate |
| OCR | đ = 8 real examples (weak diacritic column) | synth đ/d pair crops, sign-font family, diacritic-clear fonts |
| OCR | 100% on postcards, 53% on real photos | synthetic backbone → real-data fine-tune; measure camera noise |
| OCR | detector false positives (39 empty crops) | box textness/score filter + glare pre-processing |
| TTS | all voices ~52% vs sr_RS 22.3% | treat TTS source as eval confound; eval buckets per phoneme set |
| TTS | espeak sr phonemes on 72% of bs utterances | verify espeak.voice + base model; phoneme-cache diagnostic |
| TTS | ~52% ceiling / mel plateau | grapheme-VITS run skips espeak (bs is phonemic) |
Every one of those has a Reddit thread in references/sources.md.
