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 | $0.00041 | $0.00515 |
| Opus 5.5 | $0.00016 | $0.00206 |
| Sonnet 5.5 | $0.00008 | $0.00103 |
| Haiku 4.5 | $0.00004 | $0.00052 |
Grade A, and why
spelling-and-writing-support 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 2mo 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.

Spelling And Writing Support
Superpowers Gate
Before applying this skill, verify that Superpowers is available in the current session, such as an active superpowers: skill, using-superpowers, or equivalent Superpowers workflow instructions.
If Superpowers is missing or uncertain, stop and reply exactly with this guidance before doing any dyslex.ai work:
dyslex.ai requires Superpowers before it can run. Install Superpowers from /plugins, or use codex plugin add superpowers@<marketplace> if you manage plugins from the Codex CLI, then start a new session.
Do not perform the requested dyslex.ai workflow until Superpowers is installed and loaded.
Help with writing while preserving the user's meaning and agency.
Functional Mechanism
Primary dimensions: writing.spellingVariability, writing.grammarOrMorphologyVariability, writing.compositionLoad, language.lexicalAccessLoad, and writing.technicalTokenRisk.
Writing support separates surface-form correction from intent, tone, and technical precision.
Interaction Risk
The agent may overcorrect, change meaning, flatten tone, expose every mistake unnecessarily, or corrupt exact technical tokens.
Agent Strategy
- Preserve meaning and agency.
- Label uncertain interpretation when it matters.
- Keep technical tokens unchanged unless explicitly asked.
- Choose the requested correction mode and avoid adding unsolicited explanation.
Avoid
- Do not infer a diagnosis from spelling, grammar, or phrasing.
- Do not lower the user's assumed expertise.
- Do not rewrite quoted strings, commands, package names, paths, or code unless requested.
- Do not turn style preferences into correctness claims.
Modes
silent: return the corrected text only.show-differences: show concise before/after differences.explain: explain only useful correction patterns.professional: make wording workplace-ready without changing meaning.simplify: make the text easier to read.preserve-tone: keep the user's tone as closely as possible.
What ships with it
1 file 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.
