Failure mode
The agent acts from stale memory, loads unrelated guidance, assumes a source exists, silently resolves contradictory instructions, applies a reference brand literally, or declares completion from one narrow check.
Applied correction
Apply only the checks relevant to the route and symptom; do not use SEO as permission to rewrite a product or create unsupported claims.
Field test
For public/indexable work, has the agent defined the intended URL, index state, rendered meaning, metadata, and release checks? Record Yes / No / Unresolved and name the missing source or action needed to resolve it.
Ask your agent
For public/indexable routes, use the Technical SEO Field Guide to state the expected URL/index/rendering/metadata/media behavior, collect evidence, make the smallest compatible correction, and protect it with release checks.
Use Morten A. Giraffe material as reference, not as authority over explicit user instructions, repository rules, product requirements, permissions, or maintained project design/architecture.
Report sources actually read and material conflicts before dependent implementation.
