+# Code Change Considerations
+
+Use these questions while planning, implementing, and reviewing a code change. Apply them to the
+current lifecycle stage; do not turn them into a separate report when the workflow already owns an
+output format.
+
+## Authority
+
+Current code, tests, workflows, and active `AGENTS.md` files own implementation details. Derive
+paths, commands, test mappings, selectors, and architecture from the current checkout rather than
+recording them here.
+
+## Questions
+
+- What accepted outcome and current consumer require the change?
+- What current code owns the behavior, and can that owner be extended directly?
+- Would the change duplicate an existing structure or create another source of truth?
+- What state, success, failure, and partial-failure behavior must remain coherent?
+- What ordering or concurrency can change the result or bypass a guarantee?
+- How do absent values, defaults, retries, recovery, and cleanup behave?
+- Which alternate entry, error, cached, resumed, or compatibility paths can bypass the change?
+- Can code or configuration be removed, or can an existing or native mechanism replace new code?
+- What shortest stable test proves the changed behavior, including the relevant negative path?
+- Does a real process, network, filesystem, container, hardware, or service boundary require deeper
+  runtime or end-to-end evidence?
+- Which active issues, pull requests, or recent changes overlap, conflict, or affect delivery order?

+# Documentation Writing and Review Routing
+
+Use this routing contract in any skill that writes or reviews agent responses, progress updates,
+tool-call labels or descriptions, GitHub text, comments, test titles, documentation, changelog
+entries, Announcements, or maintainer guidance.
+
+## Load the Guidance for the Surface

+  It owns claim accuracy, writing rules, review scope, and terminology routing.
+- Also follow `docs/CONTRIBUTING.md` from the current NemoClaw checkout when changing public-facing

+Do not copy either guide's rules into a skill.
+
+## Complete the Assigned Review
+
+Review the complete assigned diff and PR text.
+Complete every applicable review category.
+Do not stop after the first blocking finding.
+Report all evidence-backed findings in one review result.
+
+If a finding identifies a behavior, security, data safety, test, or release ambiguity, inspect adjacent paths.
+Include unchanged sibling paths that implement the same operation or failure class.
+Group repeated findings by root cause and give representative locations.
+Do not request unrelated cleanup in unchanged text.
+
+For a sensitive operational procedure, review each applicable boundary:
+
+- Input trust and command construction.
+- Credential location, access, lifetime, transfer, and removal.
+- Command and transport status propagation.
+- Result classification for success, inconclusive verification, and infrastructure failure.
+- Action classification for rollback, retry, and stop.
+- Resource ownership, cleanup, and absence confirmation.
+- Partial external writes and authorization boundaries.
+
+Return blockers and suggestions only after completing the full assigned review. A blocker does not end the review pass.

+# Discover the Current Implementation
+
+Use the current checkout as the source of truth. A skill defines process and priorities. It must
+not maintain an inventory of paths, identifiers, commands, registrations, versions, schemas, or
+test mappings that the checkout already defines.
+
+Apply the shared [Code Change Considerations](code-change-considerations.md) at the current
+lifecycle stage.
+
+## Before implementation
+
+- Read the active `AGENTS.md` files for every area the task can change.
+- Apply the product scope gate before adding a supported surface.
+- Identify affected trust boundaries. Apply the [Security Rubric](security-rubric.md) to the plan:
+  name applicable risks, intended controls, and the positive and negative evidence the change needs.
+- During implementation and self-review, record the controls changed and negative evidence for each
+  changed control that proves forbidden behavior remains denied.
+- Verify behavior claims in current source and tests. Use history, issues, PRs, and documentation
+  for rationale, not as behavior authority.
+
+## Keep guidance current
+
+- Derive implementation surfaces, validation, and tool interfaces from the checkout when the task
+  runs. Do not copy their current details into a skill.
+- Record discovered specifics in task or PR evidence, not in reusable guidance.
+
+When a tool contributes security or provenance evidence, run the version from the trusted base
+revision. Do not treat a helper modified by the proposed change as independent evidence for that
+same change.

+# Root-Cause and Sensitive-Workflow State Checks
+
+Apply these checks while planning, implementing, and reviewing a change. Record the results in the
+output that the current workflow already owns; do not produce a separate report. State why a check
+does not apply when the omission could hide risk.
+
+## Authority
+
+Current code, tests, workflows, and active `AGENTS.md` files own implementation details. Derive the
+operations, sibling paths, and states from the current checkout rather than recording them here.
+
+## Root-Cause Sibling Paths
+
+Name the operation and failure class that the change belongs to.
+Inspect adjacent paths that implement the same operation or failure class.
+Record which sibling paths were checked and whether each one needs the same change.
+A change that repairs one path and leaves a sibling path unchanged keeps the same defect reachable.
+
+## Sensitive-Workflow State Matrix
+
+Build a sensitive-workflow state matrix as working analysis for a flow that handles credentials,
+remote execution, billable resources, destructive cleanup, security policy, or public writes. Use
+only the rows and columns required to cover the changed contract. Classify these outcomes when they
+apply:
+
+| Phase | Success | Command Failure | Transport Ambiguity | Verification Failure |
+|---|---|---|---|---|
+| Input or credential acquisition | Result and custody | Removal or rollback | Assume possible remote effect | Rejected input |
+| Execution | Expected state | Failure classification | Confirmation requirement | Acceptance criteria not met |
+| Cleanup | Confirmed removal | Recovery action | Ownership and absence check | Retention and rotation |
+| External write | Accepted write set | Partial-write report | Assume a possible write and re-read external state | Report a partial or inconclusive result |
+
+For each credential, name its location, access, lifetime, and removal. For each failure cell, record
+the result and required action separately. Classify the result as an infrastructure failure or
+inconclusive verification when applicable. Classify the action as rollback, retry, or stop. Ask the
+user before choosing a behavior that changes security, data safety, cost, or a supported contract.
+
+The [Security Rubric](security-rubric.md) owns the authentication and authorization category and its
+evidence expectations. For a public or external write, record the positive and negative evidence that
+authorization is enforced for the exact resource and action.
