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 | $0.04839 | $0.04839 |
| Opus 5.5 | $0.01936 | $0.01936 |
| Sonnet 5.5 | $0.00968 | $0.00968 |
| Haiku 4.5 | $0.00484 | $0.00484 |
Grade A, and why
texttile AGENTS.md 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 9d 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 — 369 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Texttile
Texttile is a blog CMS for two people who write together. Phoenix, LiveView and SQLite in one Docker image. One volume holds the whole installation: the database and every uploaded file. Nothing else is needed to run it.
You can think of Texttile as a self-hosted alternative to WordPress, Ghost and Substack, in the spirit of "one container, your data".
What makes Texttile special?
These are the promises the product is built on. Keep them intact.
1. Nothing is loaded from outside
A reader's browser talks to this server and to nothing else. No CDN, no third-party script, no tracker, no captcha, no hosted font, no external video player. The statistics are counted here, the spam filter runs here, the mail leaves from here. A change that adds an outside call breaks the product, not just a rule.
2. Light enough for a slow line
Texttile is written for a person reading on a phone far from a data center. Pages stay small, JavaScript stays little, and a picture is only ever as large as the screen asks for. Weigh every kilobyte you add. Continuously repainting animations are out; they cost the reader battery and the writer frames.
3. Written together
Two people work on the same entry at the same time. The title and body are locked, and only softly: the holder writes, the other one watches the text arrive live and can take over in one click. Tiles, tags, settings and publish controls stay free for both, last write wins per field. The admin area shows who is on which screen. This is the hero feature, and it is why the lock is a GenServer and not a database column.
4. The writer's Markdown, byte for byte
The body is plain text, not a document tree. What the writer typed is what is stored, character for character, so a version diff shows real edits and nothing else. Never normalize, reflow or clean Markdown, and never introduce an editor that serializes it from a tree (ProseMirror, TipTap, Milkdown).
5. Minimal, and everybody is an admin
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.
