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

tldr-update 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 9d 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

TLDR Update

When invoked, run the update CLI via Bash and report the result. Do not invent SHAs — quote the command output.

How to run

Pick the first that applies:

  1. Local checkout — if bin/install.js exists here:
    node bin/install.js update $ARGUMENTS
    
  2. tldr on PATH:
    tldr update $ARGUMENTS
    
  3. Fallback:
    npx -y github:0p9b/TLDR -- update $ARGUMENTS
    

Useful flags

Flag Effect
--check Report available update; do not apply
--dry-run Show git + reinstall plan; write nothing
--ref <tag|branch> Update to that ref (alias: --tag)
--force Hard-reset local checkout to origin/<ref> if ff-only fails (never force-pushes)

Report

Tell the user: before SHA, after SHA, source path, and what the installer reinstalled. Exit code 0 = success / already up to date; 1 = failure.

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.
