Why use it?
They explain where the project’s source files live and which files should be edited first, reducing the risk of changing generated or incorrect copies.

Instructions file for Claude Code

Written for Claude Code: SessionStart hook event. Also seen: mentions CLAUDE.md; mentions subagents; reads ~/.codex paths.

This is 0p9b/TLDR's own configuration. It tells Claude Code how to work on TLDR itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything TLDR configures →

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

TLDR CLAUDE.md 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 1mo 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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Native (no-npx, self-contained) providers install a fenced always-on TLDR ruleset into the agent's global instruction file plus the full auto-discovered TLDR skill suite (the 8 `OPENCODE_SKILL_DIRS`: `tldr`, `tldr-commit

Edit rules

  • Edit source first: skills/**, agents/**, src/**, bin/**, commands/**.
  • Run python3 tests/verify_repo.py before any commit touching skills, agents, hooks, plugins, or installer code.
  • Do not add legacy package names, legacy hook markers, or legacy skill paths to shipped code/docs.
  • Historical lineage belongs in docs/legal/ATTRIBUTION.md, docs/legal/THIRD_PARTY_NOTICES.md, or data/**, not in install paths or public commands.

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.
