The model is declared extra="forbid" — unknown keys raise
ProbeValidationError at load time. The loader walks
src/agent_guardian/probes/asi**/*.yaml and *.yml recursively.
Mix of numeric AML.T* ids and named techniques (AI Agent Context Poisoning, Memory Manipulation, Escape to Host, …).
csa_category
CsaCategory enum
yes
CSA Agentic Risk taxonomy bucket.
The triple-framework gate in
_coerce_probe
runs before pydantic validation — missing or empty values raise
ProbeValidationError with an explicit message rather than a generic
pydantic error.

Every loader raises ProbeValidationError on the first failing
probe. The error message includes the source file and the failing
field path.
Pick a <2-letter> agent code that matches the specialist (e.g.
GH for goal-hijack, TA for tool-abuse, MP for memory
poisoning). Listed in list-agents.
Pick the next free 3-digit suffix in the same asi/agent series.
Write the YAML.
Add a fixture row to the corpus tests so a regression on the
loader catches missing fields.
Bump PROBE_CORPUS_VERSION in probes/loader.py:34 + the
sibling _meta/version.yaml stamp.
The triple-framework gate makes step 4 the contentious one — you
must declare the OWASP ASI 2026 category, at least one MITRE ATLAS
technique, and a CSA Agentic Risk category. If your probe doesn’t fit
any of those, the answer is usually that it’s not the right probe to
ship in the OSS corpus yet.
Don’t ship a probe with severity: critical without a
reproducible PoV. Every critical-severity finding triggers the
high-severity band cap (clamps the headline to 79). A noisy
critical probe ruins the trend graph for every consumer.
Don’t declare mitre_atlas: [] to skip the triple-framework
gate. The loader rejects empty lists explicitly — that’s the gate
doing its job, not a bug.
Don’t put PII or real customer prompts in seeds. The corpus
is public. Seeds should be synthetic adversary turns.
