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 B, and why

ashlr-brief scanned grade B with 1 finding 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.

Recursive force deletemediumDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

1. **Destructive actions** — `rm -rf`, `git reset --hard`, `git push --force`, `DROP TABLE`, dropping migrations, deleting branches, killing processes

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

How it starts

The opening of the file, as written. The whole thing — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Ashlr Brief

Reduce token spend by trimming Claude's output, not just tool I/O. Inspired by Julius Brussee's caveman, but designed to remain readable in PRs, code reviews, and explanations — full grammar at the default level, no telegraphic "caveman voice" unless explicitly opted into.

Activation

Three ways to activate:

  1. Slash command/ashlr-brief on standard
  2. Natural language — "be brief", "tldr", "less tokens", "stop being brief"
  3. Eco mode/ashlr-eco-mode on auto-activates standard if no level is already chosen

Persistence: the active level is written to ~/.ashlr/brief.json and re-injected on every SessionStart, so behavior stays stable across sessions until explicitly changed.

Intensity levels

lite — professional terseness

  • Drop: filler ("just", "really", "basically", "actually", "simply", "essentially", "in order to"), hedging ("might possibly", "I think it could"), self-narration ("Let me look at...", "I'll now...")
  • Keep: articles, complete sentences, paragraph breaks, full grammar, all explanations the user asked for
  • Tone: professional, direct, like a senior engineer in a code review
  • Expected output reduction: ~25–35%

standard — default — drop padding, keep grammar

  • All of lite, plus:
  • Drop transition padding ("Now that we have X, let's move on to Y", "As you can see")
  • Replace verbose constructions with short ones ("in order to" → "to", "due to the fact that" → "because")
  • Cut restating-the-question preambles
  • One-sentence summaries instead of "Here's what I did:" lists when the diff already shows it
  • Keep: complete sentences, articles, code blocks untouched
  • Expected output reduction: ~35–45%

concise — fragments + arrows allowed

  • All of standard, plus:
  • Sentence fragments OK when meaning is clear
  • Arrow notation for causality (X → Y instead of "X causes Y")
  • Common abbreviations OK (db, auth, cfg, req, res, fn, ctx)
  • Bullets over prose for lists of 3+
  • Keep: Code blocks, error messages, file paths, identifiers — never abbreviated
  • Expected output reduction: ~50–60%

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.
