What it does
Fluent Feedback Formatter is an agent skill from m98/fluent. Canonical feedback template for every learner answer in the Fluent system — celebrate correct parts, correct mistakes with category and brief explanation, show the full correct version, score out of 10, and classify severity (🔴 critical / 🟡 moderate / 🟢 minor). Use in every practice session (fluent-writing, fluent-vocab, fluent-speaking, fluent-reading, fluent-review) immediately after the learner submits an answer.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Linting and formatting. The repository describes itself as: The AI Language Learning Kit for Claude Code and others. The licence is MIT.
When your agent uses it
- Tasks that involve Linting and formatting
Example prompts
- “/fluent-feedback-formatter”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 86fb80f. 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 (its code samples are markdown).
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
Fluent Feedback Formatter loads about 1.2k tokens when it runs. Until then it costs about 112 tokens; SKILL.md has 505 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.

- fluent-feedback-formatter
- description
- Canonical feedback template for every learner answer in the Fluent system — celebrate correct parts, correct mistakes with category and brief explanation, show the full correct version, score out of 10, and classify severity (🔴 critical / 🟡 moderate / 🟢 minor). Use in every practice session (fluent-writing, fluent-vocab, fluent-speaking, fluent-reading, fluent-review) immediately after the learner submits an answer.
Feedback Formatter
Overview
Every practice session ends each turn with immediate feedback. Consistency matters — the learner builds mental models from the structure, and error patterns we mine from session files depend on predictable markers (❌, ✅, severity emoji). This skill defines the single feedback shape used across all Fluent practice skills.
When to Use
Load this skill whenever the tutor:
- Grades a learner answer in any practice skill (
fluent-learn,fluent-vocab,fluent-writing,fluent-speaking,fluent-reading,fluent-review). - Needs to classify an error by severity before writing to
mistakes-db.json. - Needs to tag an error by category (grammar, vocabulary, prepositions, etc.).
Skip this skill for non-feedback output (greetings, summaries, progress reports).
Instructions
1. Standard template
{✅ or ❌} {one-line encouragement or gentle correction}
**Corrections:**
- ❌ "{wrong_part}" → **"{correct_part}"** ({category} — {brief_why})
- ✅ "{correct_part}" — {specific_praise}
**Correct version:**
"{full_correct_sentence}"
**Score: {X}/10** {emoji} {short_comment}
---Skip the ❌ block if the answer is fully correct. Skip the ✅ block only if truly nothing was right (rare — usually at least word order or intent was right).
2. Tag severity on every error
| Symbol | Severity | Meaning | Example |
|---|---|---|---|
| 🔴 | Critical | Breaks communication or exam-blocker | Formal/informal mix in formal email; wrong subordinate-clause word order |
| 🟡 | Moderate | Noticeable but understandable | Preposition error, missing article |
| 🟢 | Minor | Low priority | Spelling, punctuation, accent marks |
A single answer may contain multiple errors of different severity — tag each.
3. Use these category labels
These feed mistakes-db.json:
grammar— word order, conjugation, clause structureformal_informal— u/je, uw/jouw, register mismatchvocabulary— wrong word, English mixing, register-wrong synonymspelling— minorprepositions— om/op/in/bij/naar/etc.articles— de/het, definite/indefinitemissing— omitted greeting, closing, required word
4. Tone rules
- Encourage before correcting. Open with a ✅ or a warm ❌ (
"Close! Let's tune one word."), not a bareWrong.. - Explain why, not just what.
"Ik schrijf je" → "Ik schrijf u" (formal_informal — business emails require u)beats"Use u not je.". - Name the pattern. Helps the learner generalize:
"This is the omdat word-order rule: verb goes last.". - Celebrate progress.
"You didn't miss this last time — well done."whenmistakes-dbshows improvement. - Emojis on. The learner's profile has
use_emojis: trueby default. Keep them.
Show full SKILL.md (195 more words)Show less
5. Hand score to SM-2
After scoring, feed the score into the SM-2 update via the fluent-sm2-calculator skill: quality = floor(score / 2).
Examples
See .claude/references/feedback-template.md for fully-rendered examples (mostly-correct answer with a minor slip; critical error with severity tagging). The reference file is the authoritative version — keep it and this skill in sync if updating.
Quick pattern:
- Fully correct: open with ✅, skip ❌ block, list 1-2 ✅ strengths, show "Correct version" for echo, score 9-10/10.
- Mistakes: open with warm ❌, list each correction with severity emoji + category + brief why, show full correct version, score with breakdown if the answer is long.
Critical Rules
- Always use the template exactly. Deviations break session-file parsing downstream.
- Severity tag is mandatory on every ❌ line. Drives spaced-repetition priority.
- One score per answer. Total out of 10, with optional breakdown (grammar/vocab/structure) for long answers like writing tasks.
- Never skip the "Correct version". Even if perfect, echoing the target form reinforces motor memory.
Why This Matters
Structured, consistent feedback:
- Lets the learner scan for what to fix at a glance.
- Makes session files parseable so
PRACTICE.mdanalysis +/resultsmining work. - Populates
mistakes-db.jsoncategories cleanly — which feeds spaced repetition, which drives the whole system.
