Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Summary
agentsentrypoint, capability flags, and validation modes documented in the specificationtdd_expected_failtags from coverage threshold regression tests now that the bug fixes have landedMotivation
Specification §Tool Registry and §Validation Mode require a discoverable reference that demonstrates how tools and validations share the unified registry, how capability flags affect execution, and how wrapped validations reuse existing tooling. QA reviewers flagged the missing showcase as a documentation gap during the March doc audit.
Changes
docs/showcase/cli-tools/tool-and-validation-management.md: Added clarification on capability flag display behaviordocs/showcase/examples.json: Added new showcase example entry with commands and metadatarobot/coverage_threshold.robot: Removed obsoletetdd_expected_failtags from two test casesTesting

Reviewed this docs-only PR adding a showcase example for tool and validation management CLI commands. The markdown documentation itself is well-written and comprehensive. However, there are several critical issues that must be addressed before merge.
🔴 Required Changes
1. [CRITICAL — DATA LOSS]
examples.jsonOverwrites Existing Examplesdocs/showcase/examples.jsonexamples.jsoncontains only 1 example (the new tool-and-validation-management entry), but the master version contains 3 existing examples (output-format-flags, actor-management-workflow, server-and-a2a-integration). This PR removes all 3 existing examples and replaces them with just the new one.examplesarray, not replace it. The resulting file should have 4 entries total. Also preserve the existinglast_updatedfield behavior (master hasnull, branch sets"2026-04-07"— setting a date is fine, but don't lose the existing entries).2.

The branch appears to be behind master.examples.jsonconflict is the likely culprit given the data loss issue above.🟡 Documentation Accuracy Concerns

Review Context
This is a follow-up review after the implementer addressed the critical
examples.jsondata loss issue and rebased the branch. I verified the fixes and performed a deep review of the documentation accuracy by cross-referencing against the actual CLI source code (src/cleveragents/cli/commands/tool.py,src/cleveragents/cli/commands/validation.py) and the specification (docs/specification.md).✅ Previously Reported Issues — Now Resolved

3. [BEHAVIOR-CORRECTNESS] Capability and Resource Slot Display Inconsistency
Location:
docs/showcase/cli-tools/tool-and-validation-management.md— Step 1 vs Steps 6-7Issue: In Step 1 (
tool add), the registration output shows full capability flags:But in Step 6 (
tool show), the same tool shows:And in Step 7 (JSON output), it shows
"capability": {}(empty object).Root Cause Analysis: I traced this through the CLI source code. The
Tool.as_cli_dict()method (tool.py domain model, line 509-521) always serializes full capability flags. However, the_tool_spec_dict()fallback in the CLI (tool.py CLI, line 126) usestool.get("capability", {})for dict-like objects from the repository layer, which may return an empty dict if the repository doesn't hydrate capability data. This means thetool addcommand (which returns the domain model directly) shows full capabilities, whiletool show(which goes through the repository) may not.Impact: This is confusing for users — they register a tool with explicit capabilities and resource slots, then when they inspect it, those fields appear empty. A user following this tutorial would reasonably wonder if their registration was incomplete.
Suggested Fix: Either:
This is a medium-severity documentation accuracy issue — not blocking by itself, but should be addressed for a showcase document that's meant to teach users.

🔴 Required Changes
1. [BEHAVIOR-CORRECTNESS] Validation YAML configs missing
timeoutfields, but outputs show non-default valuesLocation:
docs/showcase/cli-tools/tool-and-validation-management.md— Steps 2, 3, and 4Issue: The YAML configs shown for the two validations do not include a
timeoutfield:required-validation.yaml(qa/coverage-check): Notimeoutin YAMLwrapped-validation.yaml(qa/lint-check): Notimeoutin YAMLYet the
tool listoutput in Step 4 shows:And the JSON output in Step 7 shows
"timeout": 120and"timeout": 180respectively.Only
custom-tool.yaml(local/line-counter) correctly showstimeout: 60in the YAML, matching the output.Impact: A user following this tutorial would copy the YAML configs as shown, register the validations, and then see different timeout values than expected. The YAML configs are incomplete — they're missing the
timeoutfields that produce the 120s and 180s values shown in the output. This is a factual inaccuracy in the documentation.Required Fix: Either:
timeoutfields to the YAML configs shown in Steps 2 and 3 (e.g.,timeout: 120forrequired-validation.yamlandtimeout: 180forwrapped-validation.yaml), OR2. [REQUIREMENTS-COVERAGE] JSON output for validations does not expose the
modefieldLocation:

tool list --format jsonoutput shown in Step 7 includes validation entries without amodefield:The
modefield (requiredorinformational) is absent. This means users who want to script against validation modes cannot do so usingtool list --format json.Spec Reference: Issue #4565 acceptance criteria: "The guide explains capability flags, resource slots, validation modes, and JSON output for scripting." The JSON output section does not demonstrate how to access validation modes programmatically.
Impact: The scripting section (
jqexamples) shows how to filter bytool_type, count tools, and check timeouts — but not how to check or filter by validation mode. A user following this guide would not know whethermodeis available in JSON output at all.Required Fix: One of the following:
tool show qa/coverage-check --format jsonincludes themodefield, add that example to Step 7 and ajqscripting example:agents tool show qa/coverage-check --format json | jq '.data.mode'modeis genuinely absent from all JSON output, add a note in Step 7 explaining this limitation: "Note: Themodefield is not included in JSON output. Usetool show <name>(rich format) to inspect validation mode."tool list --format jsondoes includemodefor validations (and the output shown is incorrect), update the JSON output to include themodefield🟡 Minor Suggestions (Non-blocking)

Specification says (spec line 7837):
There is no mention of soft-deletion anywhere in the spec. The tool is removed from the registry. Calling it a "soft-delete" is misleading and inaccurate — it implies the record is retained in a deleted state and could be recovered, which is not the specified behavior.
Required: Change "soft-deletes the tool from the registry" to "removes the tool from the registry."

The showcase output showsValidation Mode: required(good) but noAttached Tosection at all.Furthermore, the spec (line 138) states validations are "always attached to a resource."

validation attachLifecycle Step Is MissingLocation:
docs/showcase/cli-tools/tool-and-validation-management.md— Overview and Steps 2/3Issue: The spec (line 9264) explicitly states:
And (line 9270):
The showcase registers two validations (
qa/coverage-checkandqa/lint-check) but never attaches them to any resource. This omits a critical part of the validation lifecycle. The "What You'll Learn" section also does not mentionattach/detach. The showcase gives users the impression that registering a validation is sufficient for it to be active, which is incorrect per the spec.Required: Add at least one step demonstrating
agents validation attach(e.g.,agents validation attach local/my-repo qa/coverage-check) andagents validation detach <ATTACHMENT_ID>. This is a core part of the validation management workflow that the showcase title promises to cover.6. [SPEC ACCURACY] JSON Output Missing

Reviewed PR #4212 with focus on security-concerns, input-validation, and access-control.
This is a documentation-only PR adding/updating a showcase example for tool and validation management. The content itself is well-structured and educational, but there are critical CONTRIBUTING.md violations and security documentation gaps that must be addressed before merge.

4. [SECURITY] Inline Code Execution Examples Lack Security Guidance
Location:
docs/showcase/cli-tools/tool-and-validation-management.md— Steps 1 and 2Issue: The documentation demonstrates the
code:block feature (inline Python execution) without any security warnings or guidance. The examples show:This pattern has a path traversal risk —
inputs["file_path"]is used directly inpathlib.Path()without any validation. A user following this example verbatim could write a tool that allows arbitrary file system access.Similarly, the coverage check example passes
inputs["coverage_json"]directly tojson.loads()without size or content validation.Required: The documentation should include a security note explaining:
code:blocks execute in a sandboxed environmentinputsvalues should be validated before use (e.g., path canonicalization, size limits)human_approval_required: Trueshould be set (the example showsFalsewithout explaining the security implications)Suggested fix — add a "Security Considerations" callout:
5. [SECURITY / ACCESS CONTROL]
human_approval_required: FalseShown Without ContextLocation:
docs/showcase/cli-tools/tool-and-validation-management.md— Step 1 outputIssue: The expected output shows
human_approval_required: Falseas part of the capability flags, but the documentation does not explain when this should beTrue. Users may copy the example without understanding the security implications of disabling human approval.Required: Add a brief explanation of when
human_approval_requiredshould be set toTrue(e.g., tools that write files, execute commands, make network requests, or have irreversible side effects).⚠️ Minor Issues (Non-blocking)
6. PR Title vs Commit Message Mismatch
PR title: "docs: add showcase example for tool and validation management"
Commit message: "docs: update examples.json index with tool and validation management example"
The
tool-and-validation-management.mdfile already existed onmaster(it was modified, not newly created). The commit message is more accurate. Consider aligning the PR title to reflect that this is an update/enhancement to an existing example.✅ Good Aspects
Type/Documentationlabel ✅docs: ...) ✅read_only,writes,idempotent,unsafeall shown ✅--updateflag documented — prevents accidental duplicate registration ✅--yesflag for scripting — good automation pattern ✅resource_slotsaccess control pattern well-documented ✅Deep Dive: Security, Input Validation, Access Control
Security Concerns:
code:block feature is powerful but potentially dangerous. The documentation presents it without security framing. Users will learn to write inline Python that processes arbitrary inputs without guidance on safe coding practices.transform:function truncates error output (errors[:5]) which is good practice, but this is incidental rather than intentional security guidance.Input Validation:
input_schemais enforced at runtime before thecode:block executes. This should be clarified.inputsvalues within the code block itself.Access Control:
resource_slotsconcept (showingfs-mount, read_only) is a good access control pattern and is well-documented. ✅capability.writes: falseflag is shown but not explained in terms of enforcement — is this enforced by the runtime or advisory only?Decision: REQUEST CHANGES 🔄
The three CONTRIBUTING.md violations (empty PR body, missing closing keyword, missing commit footer) are blocking issues. The security documentation gaps should also be addressed to prevent users from writing insecure tools based on these examples.

1. CHANGELOG.md Not Updated
The branch CHANGELOG.md does not contain an entry for this PR. The

The master version includes theHAL 9000 <hal9000@cleverthis.com>contributor entry that is absent from the branch. Merging this PR would delete the HAL 9000 contributor entry — a regression.Required: Rebase onto master so CONTRIBUTORS.md is at parity with master, then add any new contributor entry if applicable.
3. PR Is Not Mergeable (Conflicts)
The PR metadata shows
