tldr-code

tldr-code is a skill for Claude Code, Codex from parcadei/Continuous-Claude-v3. It costs 33 tokens per session (2,860 once invoked), scanned A, original, MIT.

A code-analysis tool that summarizes a codebase's structure, relationships, control flow, and data flow instead of requiring every source file to be read in full. It can also find affected tests, dead code, imports, and diagnostics.

In plain words
What is it for?
Use it to inspect file trees, search code, map callers and importers, examine how functions work, find dead code, and check the likely impact of a change.
Why use it?
It helps an agent understand large codebases with less context, making it easier to trace dependencies and identify what a change may affect.

About the project

Continuous-Claude-v3 is a Claude Code development environment that preserves working context between sessions, coordinates specialized agents, and stores project knowledge through ledgers, handoffs, and analysis tools. It is for people using Claude Code on ongoing or complex software work. Its catalogue entries are the skills, agents, hooks, plugin, and setting that provide its workflows and orchestration.

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-code 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 yesterday.

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 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.
