Keeps credentials, company names, personal names and PII out of the model's context. Enforcement lives in Claude Code hooks rather than in instructions to the agent: a skill alone cannot protect anything, because by the time the agent reads a rule the surrounding context has already been sent. Credentials are removed irreversibly and marked. Entities from a user-supplied dictionary become stable aliases, rewritten back to real values on their way to disk and to the shell, so code and commands referring to them still work. Published from a clean tree; development history is not included.

description: Turn a block of text (ticket, log, email) into an aliased version safe to paste
|
|
---
|
|
|
|
The user has text containing sensitive data and needs an aliased version they can
|
|
send. A hook cannot rewrite a prompt, only block it, so this is the supported route.
|
|
|
|
Ask the user to paste the text into a file (or use text they already have on disk),
|
|
then run:
|
|
|
|
```
|
|
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/ctxguard.py" sanitize < <file>
|
|
```
|
|
|
|
The aliased text goes to stdout; a per-rule summary goes to stderr.
|
|
|
|
Note: only values already in the dictionary become aliases. Credentials and PII are
|
|
detected by pattern regardless. If a company or person came through untouched, it is
|
|
not registered yet — offer `/ctx-entity`.
