How to get it
These run inside the Snappy workspace. Want this working in your business? I set skills like this up with you, in one focused week.
For developers how this skill is built, graded, and how it runs
at a glance- the short version
what's inside - the parts that make up a skill 2/4 present
A skill is just a few plain-text files. Only the main one is required. The rest are optional, added as the work needs them. This is what the skill is made of; how it runs is just below.

how it's graded - what counts as a good run 4 criteria · 2 deterministic · 2 judge
Each row is one thing a good run has to get right. deterministic means a quick check decides, pass or fail. judge means the AI reads the result and rates it. Grading each piece on its own (instead of one overall score) shows exactly where a run fell short, so the fix is obvious.
how it runs - the shared frame every skill uses 5/5 present
Every skill runs the same way. One part does the work, a separate part checks it, and a short loader hands the AI exactly what it needs for the job. Anything this skill doesn't use shows a one-line note saying why, on purpose, not by accident.
state/log/evals.ndjson - NEVER trust the shell exit code. The eval is voice.checkTone() returning zero violations — a dispatch can return exit 0 with em-dashes still in the output. The kernel shipped em-dashes because of exactly this confusion.
- ALWAYS hand the rewrite model the actual violations list, not a generic "be better." The model can only fix what it's told failed.
- Image-prompt frontmatter (layer_, metaphor_rationale, image_prompt) is §4a-exempt. Don't run checkTone on those — they go to DALL-E, not a reader. (feedback_image_prompts_not_4a.md)
- Scan for the literal string , (space-comma-two-spaces) — known kernel artifact where round-tripped em-dashes leave a residue voice.ts doesn't catch. (feedback_skool_emdash_backfill_artifact.md)
what it has learned - fixes written back in over time sample
When a run hits something this skill didn't handle, the fix gets written back into the skill so it doesn't happen again. FIXED means it was corrected on the spot. LOGGED means it's queued for a bigger rewrite. Either way, the skill gets a little better and never makes the same mistake twice.

SKILL.md- the skill, written out in plain English
content-polish
The thesis test. This skill exists because the kernel's content-polish shipped em-dashes: the shell exit code was 0 so it reported success, but the draft had two em-dashes (dead AI tells). Metrics aren't evals. In mini, voice.checkTone() runs as deterministic code inside the skill, and the eval score IS the violations-zero check, not a downstream wrapper.
Steps
1. Scope - no side effects
Run voice.checkTone(draft). Return { pass, violations }. If pass, done; log eval score 1.0.
2. Rewrite loop (if violations present)
for turn in 1..max_turns:
dispatch {
model: "gemini",
prompt: <draft> + <violation list> + <voice rules> + "rewrite, zero violations",
}
draft = response
result = checkTone(draft)
if result.pass: break
3. Flow check (long-form drafts only)
After tone passes, run voice.checkFlow(draft) on drafts ≥ 10 sentences. This catches AI-flat prose: monotone sentence length, no short punches, no flowing clauses. Score degrades to 0.5 if flow violations remain after rewrite.
const flow = checkFlow(draft);
if (!flow.pass) {
// re-dispatch with flow violations as additional instruction
// re-check after each turn, same loop as step 2
}
4. Final verdict + log
const tone_ok = checkTone(draft).pass;
const flow_ok = draft_sentences < 10 || checkFlow(draft).pass;
score("content-polish", run_id, {
score:
tone_ok && flow_ok && first_try ? 1.0 :
tone_ok && flow_ok ? 0.5 :
tone_ok && !flow_ok ? 0.5 :
0.0,
primary_issue: final_violations.slice(0, 3).join("; ") || flow.violations?.[0] || null,
turns_used: turn,
flow_profile: flow.profile,
flow_stdev: flow.stats?.stdev,
});
append("chain", { run_id, skill: "content-polish", action: "scoped", ... });
Eval
Actor: dispatch model (gemini-2.5-flash via openrouter) rewrites the draft. Auditor: voice.checkTone() - deterministic regex + banned-phrase list in state/lib/voice.ts. Two different systems, as rule #actor-≠-auditor requires.
Score convention:
| Outcome | Score |
|---|---|
Draft passes checkTone() on first try | 1.0 |
Draft fails, dispatch rewrites, re-check passes within max_turns | 0.5 |
Still failing after max_turns | 0.0 - do not ship |
The shell exit code is irrelevant. A dispatch can return exit 0 with an em-dash in its output. The eval catches that.
Gotchas
- Image-prompt frontmatter (
layer_*,metaphor_rationale,image_prompt)
is §4a-exempt. Don't run checkTone on those fields - they go to DALL-E.
- Round-tripped drafts may contain the
,artifact where em-dashes used
to be. Add a scan for the literal string if you see it.
dispatch()usespiunder the hood; make surepiis on PATH.- Rewrite prompts should hand the model the actual violations list, not a
generic "be better." Give it what failed so it can fix it.
Graduation
Sidecar at state/bin/content-polish/run.ts is the deterministic path.

Critical Rules
- NEVER trust the shell exit code. The eval is

The kernel shipped em-dashes because of exactly this confusion. - ALWAYS hand the rewrite model the actual violations list, not a generic "be better." The model can only fix what it's told failed.
- Image-prompt frontmatter (

OpenUI Resource
- Skill-owned OpenUI Lang resource:
state/skills/content-polish/resources/ui.openui. Read it before rendering or editing this skill's generated component surface. - Treat this resource as a first-class artifact of the skill, not a generic chat response. Improve it when the skill's user-facing output needs to become richer.
- System resources compose OpenUI primitives and inherit SnappyChat tokens. Use
ui_contract: brandedin SKILL.md only for deliberate platform or client visuals.
Known Pitfalls
- After tone passes on long-form (≥10 sentences), run
voice.checkFlow()- flow violations degrade score to 0.5 even with clean tone dispatch()usespiunder the hood;pimust be on PATH or the loop silently misfires- Score 0.0 = do not ship. There is no "good enough" override.
Self-Test
An agent reading this should correctly:
- [ ] Treat
voice.checkTone()zero-violations as the only success signal, not exit code - [ ] Skip checkTone on image-prompt frontmatter fields
- [ ] Pass the violations list into the rewrite prompt, not just the draft
Self-report
If this loader fell short, append a line:
echo "[$(date -u +%FT%TZ)] content-polish: <what was missing>" >> state/log/loader-feedback.log
<!-- kernel-ok: historical attribution for the PID-loader pattern. -->
Self-correcting loader (PID feedback)
This is the rule that makes loaders learn. Ported from snappy-kernel, where it demonstrably worked: the snappy-dom-cartographer skill mapped Skool admin UI once, every later ship-agent inherited the full map for free.
Before you finish, do two things:
1. Fix gaps (P - proportional). MANDATORY. If this loader didn't cover your case - if you had to read another file, run an undocumented command, work around a wrong selector, or discover a quirk - you MUST attempt an Edit to this AGENTS.md before you log.
- Default action: edit this file. Surgical. Add the missing line, table
row, or code example where it belongs. No restructuring.
- Only
LOGGEDis allowed when: the fix needs >10 lines, spans multiple
files, or requires a structural rewrite. In that case the state/regen/drain.sh queue picks it up asynchronously.
- "I didn't have time" / "it's minor" / "the next agent will figure it out"
are NOT valid reasons. Minor gaps compound - that's the whole point of this loop.
- Concrete example of a valid P-fix: discover
agent-browser screenshot
takes path positionally not as --output <path>. One line in a table. Edit it in. Do not just log it.
- The goal: the next agent never has to leave the loader.
2. Log the result.
echo "[$(date -u +%FT%TZ)] content-polish: <what was missing or fixed> [FIXED|LOGGED]" >> state/log/loader-feedback.log
FIXED= you patched this loader inline (P-fix).LOGGED= too large for inline; the PostToolUse enqueue + Stop-hook drain
will rewrite the loader from scratch on next session-end.
Do not skip this. Every agent run must leave the system better than it found it. The loader is the setpoint; you are the sensor; the gap is the error signal; closing the gap is the correction.
