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.

python3 "${CLAUDE_PLUGIN_ROOT}/scripts/ctxguard.py" audit -n 40
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/ctxguard.py" status
The audit log records rule ids, tool names and aliases — never plaintext, so it is safe to read inside a session.
Read it for false positives: a rule that keeps firing on harmless content is a rule
that will get the whole plugin switched off. Fixes, in order of preference:
add the value to allowlist / allowlist_substrings in policy.json, narrow the
rule, or add it to disabled_secret_rules.
