ctx-delete

A Cursor command for deleting sessions created by the ctx tool. Session deletion permanently removes selected data, so the command requires careful targeting.

In plain words
What is it for?
Running `ctx delete` from Cursor, with a Python fallback when ctx is unavailable. It is intended for explicit, destructive cleanup.
Why use it?
It provides a direct way to remove unwanted ctx sessions instead of running the deletion command manually.

Made for: Cursor.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 78 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

ctx-delete 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 2d 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

Experimental integration for deleting ctx sessions in Cursor.

Treat any extra text after /ctx-delete as the argument string for ctx delete.

Run:

ctx delete <arguments>

If ctx is unavailable, fall back to:

python3 scripts/ctx_cmd.py delete <arguments>

This is destructive. Be explicit about what will be deleted.

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.
