sipcode CLAUDE.md

A set of response rules for the Sipcode project that keeps coding-agent replies short and focused on file changes.

In plain words
What is it for?
It is for showing only changed sections, preferring code and bullets, and giving one clear example when editing or explaining code.
Why use it?
It reduces repeated code, introductions, summaries, and other text that can use tokens without helping with the task.

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.

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

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)

  1. 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.
  2. 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.
  3. no post-amble. don't summarize what was just shown unless the user explicitly asks for a summary.
  4. code over prose. when the answer is code, the code is the answer. any explanation goes after the code block, not before.
  5. bullets over paragraphs for any list of options, steps, or trade-offs. saves tokens versus flowing prose.
  6. one canonical example, not three. show one good example. skip the exhaustive variants — the user will ask if they want more.
  7. no filler verbs. drop "let me", "i'll go ahead and", "i'm going to". just do the thing.

Changes

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.
