SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00054 | $0.02001 |
| Opus 5 | $0.00027 | $0.01001 |
| Sonnet 5 | $0.00011 | $0.00400 |
| Haiku 4.5 | $0.00005 | $0.00200 |
Grade A, and why
lanes-writing 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 2d 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 — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Writing for Lanes
Canonical copy lives in lanes-sh/web at .claude/skills/lanes-writing/SKILL.md.
The copies in lanes-sh/link and lanes-sh/core follow it; edit the canonical one.
The reader
One person, in a hurry, who wants the thing running. They did not come to admire the architecture. Every sentence between them and a working setup is a cost, and the only justification for that cost is that the sentence saves them more than it spends.
Step 1: pick the register
Three registers. Which one a page gets depends on what success means for its reader.
| Register | Reader's success | Shape |
|---|---|---|
| Quickstart | "It is running." | Prerequisite line, numbered commands, one line of result, one link out. Reasoning goes in a Notes block at the foot |
| Layered | "I understand this well enough to decide." | What it is, what you do about it, then why it works this way. In that order, never interleaved |
| Site voice | "I know whether this is for me." | A claim, then the proof. Benefit-first subheads, second person, short paragraphs |
Look the page up rather than deciding by feel:
| Page type | Register |
|---|---|
| Quickstart, install, connect, deploy, "add it to your agent" | Quickstart |
| Per-feature how-to (worktrees, loops, gateway, sessions, issue board) | Quickstart, plus one sentence on a step with a real gotcha |
| Concept and explainer (architecture, security, scopes, identity, capabilities) | Layered |
| Reference (commands, settings, shortcuts, providers, errors, API) | Tables only. One row per thing, no prose between rows |
| README, first screen | Site voice |
| README, everything below install | Quickstart |
Index and overview (/docs, /docs/mcp, src/content/pages/*.md) |
Site voice |
| Use case, comparison | Site voice |
| Blog | Leave the voice alone. Correct facts only |
| Terms, privacy, GDPR, cookies | Plain legal English. Accuracy beats brevity. No register change |
Step 2: make every heading name an outcome
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.

lanes-writing is a skill published in the GitHub repository lanes-sh/link (34 stars, last pushed yesterday), licensed Apache-2.0. It adds 54 tokens to every session and 2,001 once invoked, about $0.0003 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 2026-09-05.
