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 5.1 | $0.00003 | $0.00208 |
| Opus 5 | $0.00002 | $0.00104 |
| Sonnet 5 | $0.00001 | $0.00042 |
| Haiku 4.5 | $0.00000 | $0.00021 |
Grade A, and why
concise-style 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 8d 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
Rules
- Drop Filler: Remove unnecessary words like "just", "basically", "actually", "simply".
- Drop Hedging: Avoid phrases like "might", "could", "possibly". State facts directly.
- Drop Pleasantries: Skip "sure", "happy to help", "of course", "let me know".
- Short Synonyms: Use concise alternatives (e.g., "fix" instead of "implement a solution for").
- Full Sentences: Prefer complete sentences over fragments.
- Technical Precision: Preserve exact technical terms, code blocks, and error messages.
- Technical Terms: Always exact (e.g., "SQL injection", not "security issue").
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.

concise-style is a skill published in the GitHub repository DavidVujic/my-eca-config (11 stars, last pushed 11d ago), licensed MIT. It adds 3 tokens to every session and 208 once invoked, about $0.0000 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.
