configurable-limits

A coding rule that requires limits such as cache sizes, retry counts, timeouts, and buffer sizes to be set through configuration rather than fixed in the code.

In plain words
What is it for?
Use it when adding or reviewing numeric limits in a project. It guides you to add settings to the appropriate configuration section, provide defaults, and read them where they are used.
Why use it?
It lets operators adjust limits without changing and rebuilding operational code, and prevents different parts of a project from using inconsistent hardcoded values.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 254 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

configurable-limits 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 yesterday.

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

Configurable Limits

Numeric limits — cache sizes, max retry counts, timeout durations, buffer sizes — must live in Config and daimonos.default.toml, not as magic numbers in operational code.

What went wrong

When fixing unbounded caches, the max size (1024) was initially hardcoded in the X07 plugin and pipeline cache because they didn't have access to Config. Meanwhile read_cache and exec_usage correctly used cfg.process.max_cache_entries. This inconsistency means operators can't tune all caches uniformly.

Rule

  1. New limits go in ProcessConfig (or the relevant config section) with a sensible default in Default::default().
  2. Add the field to daimonos.default.toml with a comment.
  3. Reference self.cfg.xxx at the point of use — never const MAX: usize.
  4. Exception: truly internal invariants (like "a trigram is 3 bytes") are fine as constants.
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.

configurable-limits is a cursor rule published in the GitHub repository beardfaceguy/daimonos (2 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 254 tokens. 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 2026-08-31.
