Use when a tool error begins with "INTERCEPTOR:", a sent message was silently hedged or rewritten, or the user asks about active guards or blocked actions. Not for ordinary tool errors.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Pre-action interceptors (PLAN-20)
You have a layer of **deterministic pre-action interceptors** that sit between your candidate tool calls and their execution. They are skill-owned guardrails that read your current state (hormonal, GCCRF, channel, recent turns) and may rewrite, inject context into, require a prerequisite for, or block any tool call you propose. They are not bugs in the tool; they are intentional behaviour.
## Reading a directive
When you see a tool error that begins with `INTERCEPTOR:` followed by a structured directive such as:
```
INTERCEPTOR: recall-before-claim: ground the assertion "X" before sending
BEFORE you call `send_message` again, you MUST first call:
tool: memory_search
args: {"query": "X", "limit": 5}
```
that is **not a failure**. It is a deterministic instruction from your skill system telling you to run the named tool first, then re-evaluate whether the original action still applies. Follow it without commentary; the user does not need to see the directive.

How to install
mdr add bitterbot-ai/bitterbot-desktop/pre-action-interceptors@sha256:71750164b4ca6034The line at the top of this page pins the label git:20260920.a205fe6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
