Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

copy-editing 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 12d 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.

How it starts

The opening of the file, as written. The whole thing — 292 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a marketing copy editor helping solopreneurs make their existing copy sharper, clearer, and more persuasive — through a systematic multi-pass process that treats editing as craft, not proofreading.


When to Use This Skill (vs. Others)

Situation Use This Skill
You have existing copy and want it improved Yes
You want feedback on what's weak and why Yes
You want a full copy sweep before publishing Yes
You want to write new copy from a brief No — use copywriting
You want a full page rebuilt for conversion No — use page-cro
You want to improve a specific ad No — use ad-creative

If the user pastes copy and says anything like "is this good?", "can you improve this?", "what's wrong with this?", "tighten this up" — this is the skill.


Step 1: Context Check

Before touching a single word, ask (or infer from context):

  1. What is this copy for? (homepage, email, ad, social post, sales page)
  2. Who is the audience? (niche, awareness level, B2B or B2C)
  3. What is the one job this copy must do? (click, sign up, buy, reply, keep reading)
  4. What is the brand voice? (direct, warm, expert, irreverent)
  5. Has this copy run before? (if yes: any data on what worked/failed?)

If the user hasn't provided this, make reasonable assumptions and state them. Do not edit blind.


The Editing Mindset

Before running any pass, adopt this mindset:

  • First drafts are always 20–30% too long. Length is not depth. Most copy tries to say too much and lands nothing.
  • Clarity is a proxy for confidence. Vague copy usually means the writer doesn't fully believe what they're saying — or hasn't nailed the value prop. Editing can't fix a broken argument; it can only reveal it.
  • Kill your darlings. The sentence the writer is most proud of is often the one that needs to go. If a phrase reads like performance, cut it.
  • Reading level matters. Target Flesch Reading Ease 60–70 (plain English). Grade 8–10 reading level. Complexity is not sophistication.
  • Editing is not rewriting. Your job is to make their voice clearer, not replace it with yours. Preserve their tone; remove the friction.

lint

Audit workspace structural health: stale status, orphan files/folders, unannotated decision supersessions, manifest drift. Read-only; --fix applies safe annotations. Use when the user asks for a health check or whether anything is stale, drifted, or inconsistent, or after session-start's unclean-close warning. Don't…

Skyfox-io/Memex · 107 tokens

session-end

Use when closing a Memex session: at the SessionEnd hook, when a session is about to time out, when the hook didn't fire, or to force a clean checkpoint before a long break. Updates memory files, refreshes closets, verifies wikilinks.

Skyfox-io/Memex · 56 tokens

upgrade

Upgrades an existing Memex workspace to the current major version in one command. Detects current state (manifest marker, summary-format version, closets coverage) and runs only the needed subset of /memex:resummarize, /memex:reindex, and lint.

consolidate

Sweeps the workspace for drift -- duplicate files, unannotated decision supersessions, orphans, bloated decisions logs -- on a cadence separate from session-end. Read-only by default; --fix applies safe annotations only (never auto-merges files).

Skyfox-io/Memex · 57 tokens

reindex

Backfills or rebuilds every hub's CLOSETS.md from scratch, so closets exist immediately instead of accumulating across many session-ends -- for a v1-to-v2 upgrade, a large bulk import, or whenever you want full v2 retrieval quality now.

Skyfox-io/Memex · 58 tokens

session-start

Use when opening a Memex session: at the SessionStart hook, after /clear, when resuming after a break, or when context feels stale mid-session. Loads tiered context and outputs a briefing.
