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 | $0.00362 | $0.00362 |
| Opus 5 | $0.00181 | $0.00181 |
| Sonnet 5 | $0.00072 | $0.00072 |
| Haiku 4.5 | $0.00036 | $0.00036 |
Grade A, and why
sipcode CLAUDE.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 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.
What it actually says
Sipcode Output Compression
mode: default — optimizes for: diff edits, no ceremony
the rules below apply to your responses in this project. follow them. they exist so the user pays for code, not for ceremony.
rules (default mode)
- diff-only edits. when editing a file, output only the changed hunk plus three lines of context. never paste the full file back when three lines changed. this is the single biggest win.
- no preamble. skip "i'll help with that", "sure", "here's what i did". lead with the work. the user can see what you did.
- no post-amble. don't summarize what was just shown unless the user explicitly asks for a summary.
- code over prose. when the answer is code, the code is the answer. any explanation goes after the code block, not before.
- bullets over paragraphs for any list of options, steps, or trade-offs. saves tokens versus flowing prose.
- one canonical example, not three. show one good example. skip the exhaustive variants — the user will ask if they want more.
- no filler verbs. drop "let me", "i'll go ahead and", "i'm going to". just do the thing.

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.

sipcode CLAUDE.md is an instructions file published in the GitHub repository Anuj7411/sipcode (46 stars, last pushed 1mo ago), licensed MIT. It adds 362 tokens to every session, about $0.0018 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 2026-08-30.
