Spec Test Analyzer

This skill uses ./docs/ as the canonical ArkTS spec corpus. It prefers the generated ./.agent/ index for fast recall, but it must remain usable in a clean checkout where ./.agent/ has not been built yet.

Directory Contract

• ./docs/: committed raw spec Markdown files and the only long-term source of truth.
• ./.agent/: generated retrieval index produced from ./docs/. Do not commit it.
• ./scripts/build_agent.sh: builds or refreshes ./.agent/ with wiki_agentizer.
• ./scripts/validate_agent.sh: validates the generated index.
• ./.tooling/: local bootstrap area for the wiki_agentizer tool, its virtual environment, and temporary build outputs. Do not commit it.

Preflight

Before analyzing any snippet or CTS failure:

1. Confirm ./docs/ exists.
2. If ./.agent/manifest.json exists, use the index-first workflow below.
3. If ./.agent/ is missing, tell the user the fast index is unavailable and choose one of these paths:
   • Recommended: run ./scripts/build_agent.sh, then continue with the index-first workflow.
   • Fallback: continue with raw-doc retrieval from ./docs/ if the task is small, urgent, or build tooling is unavailable.
4. Never treat ./.agent/ as a committed or guaranteed input in a clean environment.

Build and Validate the Index

./scripts/build_agent.sh bootstraps wiki_agentizer from https://gitcode.com/anxuesm/wiki_agentizer into ./.tooling/, checks out the pinned default commit, verifies HEAD, builds into an isolated temporary output root under ./.tooling/, then syncs the resulting ./.agent/ back into the skill root.

./scripts/build_agent.sh
./scripts/validate_agent.sh

Useful environment overrides:

• WIKI_AGENTIZER_DIR: use an already checked-out local tool directory instead of cloning.
• WIKI_AGENTIZER_REPO: override the clone URL.
• WIKI_AGENTIZER_REF: explicitly override the pinned default commit after auditing the new version.
• GIT_BIN: choose the Git executable used for clone, checkout, and HEAD verification.
• WIKI_AGENTIZER_FULL_BUILD=1: force a full rebuild instead of incremental mode.
• WIKI_AGENTIZER_CONFIG: pass a config file to wiki_agentizer.
• WIKI_AGENTIZER_JOBS: set build parallelism.
• PYTHON_BIN: choose a specific Python executable.

Trigger Conditions

Use this skill when:

• The user provides one or more ArkTS code snippets or test cases and asks which spec rules they relate to.
• The user asks to generate or complete test cases for a given syntax feature.
• The user asks to check whether existing test cases fully cover a spec section.
• The user provides a failed CTS test case and needs spec-grounded expected behavior, rule recall, or gap analysis.

CTS Defect Spec Analysis Mode

When the input is a failed CTS test case with an error message or unexpected behavior, switch to CTS defect analysis mode.

Additional work in this mode:

1. Extract the expected compiler behavior from recalled spec rules.
2. Map the observed error to a spec gap or implementation mismatch.
3. Identify the likely responsibility split:
   • Syntax parsing error -> Parser
   • Type mismatch or semantic error -> Checker
   • Code generation or desugaring error -> Lowering
4. Produce the CTS defect analysis report in the format below.

Generated Index Layout

When ./.agent/ has been built, treat these as the main retrieval artifacts:

• ./.agent/manifest.json
• ./.agent/catalog/docs_min.jsonl
• ./.agent/catalog/dirs_min.jsonl
• ./.agent/documents/
• ./.agent/sections/
• ./.agent/cache/section_index.jsonl
• ./.agent/graph/ as optional hints only
• ./.agent/reports/

graph/ data is optional acceleration data. If it is sparse or empty in the current build, the workflow must fall back to related_docs[], section metadata, and fixed chapter scans instead of failing.

Retrieval Workflow

Step 1: Syntax Feature Extraction

From each code snippet, extract:

• Keywords: language keywords present such as class, interface, extends, implements, async, and abstract
• Constructs: structural patterns such as class declarations, generic instantiations, and enum usage
• Types used: concrete types, user-defined types, unions, nullable forms, and type arguments
• Modifiers: public, private, static, readonly, abstract, override, and related modifiers
• Context: whether the code is a declaration, expression, statement, module-level construct, or type position

Step 2A: Index-First Recall

Use this path when ./.agent/manifest.json exists.

1. Scan ./.agent/catalog/docs_min.jsonl for candidate chapters.
2. Read matching document sidecars under ./.agent/documents/ to inspect keywords[], related_docs[], and entry scores.
3. Read matching section sidecars under ./.agent/sections/ to locate the most relevant headings and line ranges.
4. Scan ./.agent/cache/section_index.jsonl for cross-document section matches when the feature spans multiple chapters.

Step 2B: Raw-Doc Fallback

Use this path when ./.agent/ is unavailable.

1. Search ./docs/ with rg using extracted keywords, syntax names, and expected chapter terms.
2. Prioritize chapter files that map naturally to the feature, such as:
   • 9_classes.md for classes and members
   • 10_interfaces.md for interfaces
   • 11_enums.md for enums
   • 5_generics.md for generics
   • 6_conversions.md for conversions
   • 15_semantics.md for semantic rules
   • 4_names.md for scope and declaration rules
3. Read the matched source text directly from ./docs/.

Step 3: Source Reading

For each matched section, read the actual spec text from the canonical source file in ./docs/:

• Use source_path, line_start, and line_end when the index is available.
• Otherwise infer the section by heading and read the matching range directly from the Markdown file.
• Always cite the source file and line range in the final analysis report.

Step 4: Cross-Chapter Expansion

For each matched rule, expand to related chapters by using this priority order:

1. related_docs[] from the generated document metadata, if present
2. ./.agent/graph/link_graph.json and ./.agent/graph/backlinks.json if they contain usable edges
3. Fixed manual chapter checks:
   • 15_semantics.md for semantic constraints
   • 6_conversions.md for conversion behavior
   • 4_names.md for scope and declaration rules
   • 5_generics.md for generic interactions

Test Case Generation Strategy

For each recalled spec section, enumerate:

1. Valid syntax variants
2. Invalid syntax variants
3. Boundary conditions
4. Modifier combinations
5. Inheritance or implementation scenarios when relevant
6. Generic instantiations when relevant
7. Success and failure behaviors

Do not duplicate cases that only change trivial literal values without changing the spec rule being exercised.

Report Requirements

Every analysis output must:

• cite the canonical source text from ./docs/
• state whether the result came from index-first retrieval or raw-doc fallback
• separate directly relevant rules from cross-chapter rules
• list uncovered or ambiguous areas explicitly

For non-CTS requests, use a compact Markdown report with:

1. Overview
2. Recalled spec sections
3. Source citations
4. Generated or missing test scenarios
5. Coverage summary
