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 | $0.00821 | $0.00821 |
| Opus 5 | $0.00411 | $0.00411 |
| Sonnet 5 | $0.00164 | $0.00164 |
| Haiku 4.5 | $0.00082 | $0.00082 |
Grade A, and why
tabless CLAUDE.md scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.
tabless — notes for coding agents
A local shelf and reader for HTML that coding agents produce. README.md says
what it is for users; this file is what you need to work on it.
Before changing anything
Read CONTRIBUTING.md first. It lists seven design constraints that are not
up for negotiation, and docs/design-notes.md records the failure behind
each one. Both exist because this codebase's hard parts are decisions, not
algorithms — the code is simple and the reasons are not.
The short version, so you recognise when you are about to cross one:
- One reader window, ever. Projects are tabs.
- No process management. A
liveentry whose service is down opens blank, on purpose. - Copies, never references.
- No required third-party dependencies (
pyyamlis optional and must degrade silently). - Loopback only.
- Types stay an open set; nothing in the reader may key off a specific type name.
- Starring lifts an entry out of its group rather than duplicating it.

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.

tabless CLAUDE.md is an instructions file published in the GitHub repository starless0912/tabless (2 stars, last pushed 1mo ago), licensed MIT. It adds 821 tokens to every session, about $0.0041 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
