toml-string-safety

toml-string-safety is a cursor rule for Cursor from zhangdszq/teamclaw. It costs 0 tokens per session (246 once invoked), scanned A, original, Apache-2.0.

Rules for safely preparing text before parsing TOML, a configuration-file format. They focus on preserving triple-quoted multi-line strings while correcting common generated TOML mistakes.

In plain words
What is it for?
Use it when maintaining fixTomlArrayTables or handling TOML generated by a language model, especially strings with inner quotes and array-table headers.
Why use it?
It prevents preprocessing from damaging valid multi-line text or leaving invalid TOML that cannot be parsed.

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

toml-string-safety 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 5d 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

TOML String Pre-processing

fixTomlArrayTables pre-processes LLM-generated TOML before parsing.

Critical: Preserve triple-quoted strings

TOML """...""" multi-line strings must NOT be matched by single-line quote fixers. Always use negative lookahead (?!"{3}) before matching "(.*)" patterns.

// BAD — mangles """ into "\""
/^(\s*\w[\w.-]*\s*=\s*)"(.*)"$/gm

// GOOD — skips triple-quoted lines
/^(\s*\w[\w.-]*\s*=\s*)(?!"{3})"(.*)"$/gm

Common LLM TOML mistakes to handle

  1. Unescaped inner quotes: description = "识别为"值得沉淀"的标准"
  2. Misformed multi-line strings: system_prompt = "\"" followed by bare text
  3. Missing [[array]] table headers turning into invalid keys
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.
