Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00084 | $0.04386 |
| Opus 5 | $0.00042 | $0.02193 |
| Sonnet 5 | $0.00017 | $0.00877 |
| Haiku 4.5 | $0.00008 | $0.00439 |
Grade A, and why
humanize-en 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 yesterday.
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 — 153 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Humanize EN
Strip AI writing tells from English prose. Preserves meaning, structure, code blocks, links, anchors, and frontmatter — rewrites only the flagged phrasing.
Additional context from the user: $ARGUMENTS
Scope
This skill removes AI slop. Default mode (no -f): the goal is a clean, direct, human-edited register that preserves the source voice — universal AI tells stripped, no opinion injected. If the source is an opinion piece and the user explicitly asks for voice, references/voice.md covers the optional voice-calibration pass.
Under -f <voice-doc>, the brand voice is the primary contract. Prescan and validation enforce mechanically detectable rules; the LLM reviews the remaining semantic rules. A mechanical clean result covers only those detectors, not every brand rule. Preserve source facts, code and quotations throughout.
Brand voice integration (optional)
When $ARGUMENTS starts with -f <voice-doc>, load a BRAND-VOICE.md (typically produced by /brand-voice) and treat its rules as the primary contract on top of the universal 32 patterns.
$SKILL_DIR = this skill's folder — ${CLAUDE_SKILL_DIR} in Claude Code, the directory containing this SKILL.md elsewhere.
Workflow:
- Strip
-f <voice-doc>from the head of$ARGUMENTS. The remainder follows the Input modes table below as usual. - Verify
<voice-doc>exists and is readable. Missing explicit brand input blocks brand-aware completion; report the exact path/error instead of silently substituting universal-only success. - Resolve once. Find the installed brand-voice skill through the harness, then its
scripts/extract_rules.py; known fallback locations are the sibling skill and~/.agents/skills/brand-voiceor~/.claude/skills/brand-voice. Runpython3 <extract_rules.py> --resolved-json <voice-doc> > <temporary-rules.json>and read that JSON as the LLM's rule contract. It resolvesvoice.extendsand_replace/_removethrough the existing resolver. On failure, preserve stderr and stop brand-aware completion. If the resolver is absent and the voice has no inheritance, read its local YAML and use--brand <voice-doc>for both checks. Inherited input requires the resolver: reportnpx skills add coroboros/agent-skills --skill brand-voice, then the exact extraction and rerun commands; never claim parent coverage from child-only input. - Run the brand-aware prescan:
python3 "$SKILL_DIR"/scripts/prescan.py --rules-json <temporary-rules.json> <file>. Use the same resolved JSON for the LLM and both mechanical checks; do not rescan the original child path. Local-only fallback uses--brandinstead. Brand hits carrysource: "brand"and arule_idalongside the 8 mechanically detectable universal patterns. - Cite per source. Name each hit by source: pattern numbers for universal (
#14), brandrule_ids for brand ([no-hedging-imperative],[forbidden_lexicon:game-changing],[all_caps_emphasis]). Brand rules win on direct conflict — a voice that requires em-dashes overrides pattern #14. - Validate the authorized edit with
python3 "$SKILL_DIR"/scripts/validate.py --rules-json <temporary-rules.json> [--baseline <pre-rewrite-hits.json>] <file>(or the local-only--brandinput selected above).cleanends the mechanical pass; include semantic coverage before completion.residuals→ surface and iterate within the cap;regression→ repair the offending edit. Audit-only may validate a temporary proposed rewrite, leaving the target unchanged. - Pseudo-tables (
```textor unspecified-language fences) are scanned the same as prose under-f— see Preservation rules. Real code (```python,```bash, etc.) stays verbatim.
What ships with it
21 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

humanize-en is a skill published in the GitHub repository coroboros/agent-skills (4 stars, last pushed 2d ago), licensed MIT. It adds 84 tokens to every session and 4,386 once invoked, about $0.0004 per session on Opus 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 2026-08-31.
