Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00073 | $0.00356 |
| Opus 5 | $0.00036 | $0.00178 |
| Sonnet 5 | $0.00015 | $0.00071 |
| Haiku 4.5 | $0.00007 | $0.00036 |
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:
- Local checkout — if
bin/install.jsexists here:node bin/install.js update $ARGUMENTS tldron PATH:tldr update $ARGUMENTS- 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.
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.

tldr-update is a skill published in the GitHub repository 0p9b/TLDR (23 stars, last pushed 16d ago), licensed MIT. It adds 73 tokens to every session and 356 once invoked, about $0.0004 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.

Read and send mail from the user's own Gmail or Outlook account, safely stage Gmail draft attachments, send from the agent's own address, manage Outlook contacts, and work with Google Drive files — with co gmail, co outlook, co email, and co gdrive.

Ultra-compressed reply mode. Cuts output tokens 65-75% by answering in terse "caveman" style while keeping full technical accuracy, and shapes what survives: action first, state restated every turn, concrete time estimates, visible wins.
