## Notes

- **Checkpoint folder naming:** The specification references `.checkpoint/` while the SKILL.md implementation uses `.x-ipe-checkpoint/`. This is a deliberate rename for namespace clarity (avoiding collisions with generic `.checkpoint` dirs). All AC-050A-06 criteria are evaluated against the implemented `.x-ipe-checkpoint/` name since the functional behavior is identical and the rename is an improvement. The `references/handoff-protocol.md` still uses the old `.checkpoint/` name — a minor internal inconsistency to clean up.
- **loaded_tool_skills vs loaded_tool_skill:** The specification AC-050A-01c says "loaded_tool_skills" (plural). The implementation uses singular `loaded_tool_skill`, consistent with BR-3 (one category per run). Functionally satisfied.

## Detailed Results

| AC ID | Criterion | Result | Evidence |
|-------|-----------|--------|----------|
| AC-050A-01a | SKILL.md exists with valid input/output YAML contracts | **PASS** | `SKILL.md` exists at `.github/skills/x-ipe-task-based-application-knowledge-extractor/SKILL.md` with valid YAML frontmatter (name, description, category, triggers) and both `Input Parameters` (lines 41–64) and `Output Result` (lines 321–349) YAML blocks. |
| AC-050A-01b | Input params declare: target, purpose, config overrides | **PASS** | SKILL.md Input Parameters (lines 56–63): `target: "{path or URL}"`, `purpose: "user-manual"`, `config_overrides:` with `max_retries`, `web_search_enabled`, `timeout_seconds`. Input Initialization block (lines 68–76) confirms sources. Validation gates (line 79) enforce required fields. |
| AC-050A-01c | Output result declares: extraction_status, loaded_tool_skills, detected_input_type, detected_app_type, checkpoint_path | **PASS** | SKILL.md Output Result (lines 321–349): `extraction_status`, `loaded_tool_skill` (singular — consistent with one-category-per-run), `input_analysis: { input_type, format, app_type, source_metadata }` (contains detected types), `checkpoint_path`. All five semantic fields present. |
| AC-050A-02a | Local dir with Python/JS source files → "source_code_repo" + identifies languages | **PASS** | `references/input-detection-heuristics.md` §Input Type Detection: directory with `package.json`, `pyproject.toml`, etc. → `source_code_repo`. §Format Detection: `.py → python`, `.js/.jsx/.ts/.tsx → javascript`. `execution-procedures.md` Step 1.1 DECISION block confirms. `templates/input-analysis-output.md` Examples 1–3 demonstrate with `primary_language` populated. |
| AC-050A-02b | Local dir with only markdown files → "documentation_folder" + format "markdown" | **PASS** | `references/input-detection-heuristics.md`: "Directory with only .md, .rst, .txt, .adoc files (no code files) → documentation_folder". Format table: `.md, .markdown → markdown`. `templates/input-analysis-output.md` Example 4: `input_type: "documentation_folder"`, `format: "markdown"`, `app_type: "unknown"`. |
| AC-050A-02c | Public URL → "public_url" + format "html" | **PASS** | `references/input-detection-heuristics.md`: "URL matching `https?://[^localhost].*` → public_url". `execution-procedures.md` Step 1.1: "IF `https?://*` (not localhost) → input_type = public_url". `templates/input-analysis-output.md` Example 5: `input_type: "public_url"`, `format: "html"`. |
| AC-050A-02d | Running web app (localhost:3000) → "running_web_app" | **PASS** | `references/input-detection-heuristics.md`: "URL matching `localhost:*` or `127.0.0.1:*` or `0.0.0.0:*` → running_web_app". `execution-procedures.md` Step 1.1 DECISION confirms. `templates/input-analysis-output.md` Example 6: `input_type: "running_web_app"`. |
| AC-050A-02e | Single local file → "single_file" + format based on extension | **PASS** | `references/input-detection-heuristics.md`: "Single file path (not a directory) → single_file". Format Detection table maps file extensions to formats (14 format values). `execution-procedures.md` Step 1.1: "IF single file → input_type = single_file". `templates/input-analysis-output.md` Example 7: `input_type: "single_file"`, `format: "markdown"`. |
| AC-050A-02f | Non-existent path → error message about path not accessible | **PASS** | `references/input-detection-heuristics.md`: "Path does not exist → Error". SKILL.md Validation Gates (line 80): "IF target path missing or URL unreachable → halt". `execution-procedures.md` Step 1.1 DECISION: "IF target is local directory AND empty → halt with error" + constraints: "BLOCKING: Empty directory or unreachable URL → halt with error". |
| AC-050A-03a | Source code repo with package.json + HTML entry point → "web" | **PASS** | `references/input-detection-heuristics.md` §App Type Detection: "`package.json` with `"start"` script + HTML/JSX/TSX files → web (Priority 1)". §Framework Detection lists Flask, Django, Express, Rails markers → web. `templates/input-analysis-output.md` Examples 1–2 show web classification. |
| AC-050A-03b | CLI entry point (argparse, click, commander) → "cli" | **PASS** | `references/input-detection-heuristics.md`: "argparse, click, commander, clap → cli (Priority 2)". §Framework Detection: `import argparse`, `import click`, `require('commander')`, `use clap` patterns documented. `templates/input-analysis-output.md` Example 3: `app_type: "cli"`, `framework: "click"`. |
| AC-050A-03c | Mobile framework markers → "mobile" | **PASS** | `references/input-detection-heuristics.md`: "React Native, Flutter, Swift, Kotlin → mobile (Priority 3)". §Framework Detection: `"react-native"` in package.json, `pubspec.yaml` with flutter, `.swift` + Xcode, `.kt` + Gradle. `templates/input-analysis-output.md` §Framework Values lists `react-native`, `flutter`. |
| AC-050A-03d | Documentation folder with no code markers → "unknown" + proceeds without mixin | **PASS** | `references/input-detection-heuristics.md`: "No framework markers → unknown (Priority 4)". `templates/input-analysis-output.md` Example 4: `app_type: "unknown"` for documentation folder. SKILL.md Step 1.3: "proceed without a mixin if no label matches". |
| AC-050A-04a | Discovers and loads tool skill via glob `.github/skills/x-ipe-tool-knowledge-extraction-*/SKILL.md` | **PASS** | SKILL.md Step 1.3 (line 178): "Glob .github/skills/x-ipe-tool-knowledge-extraction-*/SKILL.md, filter by category". `execution-procedures.md` Step 1.3 CONTEXT confirms exact glob pattern. `references/category-taxonomy.md` §Tool Skill Naming Convention: "Discovery: Glob `.github/skills/x-ipe-tool-knowledge-extraction-*/SKILL.md`". |
| AC-050A-04b | Loaded tool skill provides playbook template, collection template, acceptance criteria as file paths | **PASS** | SKILL.md Step 1.3 output: `tool_skill_artifacts {playbook_template, collection_template, acceptance_criteria, app_type_mixins}`. `execution-procedures.md` Step 1.3 ACTION: "Extract artifact paths: playbook_template, collection_template, acceptance_criteria". `templates/checkpoint-manifest.md` template (lines 47–52) confirms three artifact path fields. VERIFY checkpoint confirms artifact paths exist. |
| AC-050A-04c | No matching tool skill → halt with install instruction error | **PASS** | SKILL.md Step 1.3 constraints (line 183): "BLOCKING: 0 matching tool skills → halt with install instructions". `execution-procedures.md` Step 1.3 DECISION: "0 matches → halt (install tool skill)". SKILL.md Important Notes §2: "If no tool skill is found, the skill halts with error." |
| AC-050A-04d | Multiple tool skills match → selects only category-matching one | **PASS** | `execution-procedures.md` Step 1.3 DECISION: "multiple → filter by frontmatter category". SKILL.md Step 1.3 (line 178): "Glob ..., filter by category". Step 1.3 action #2: "Parse frontmatter, extract artifact paths". |
| AC-050A-05a | purpose="user-manual" → validates and proceeds | **PASS** | SKILL.md Step 1.2 (lines 165–171): "Validate against v1-supported categories (user-manual only)". `execution-procedures.md` Step 1.2: "IF purpose == 'user-manual' → selected_category = 'user-manual'". `references/category-taxonomy.md` taxonomy table: user-manual = v1 Supported ✅. |
| AC-050A-05b | purpose="API-reference" → halt "not supported in v1" | **PASS** | `execution-procedures.md` Step 1.2: "IF purpose in ['API-reference', 'architecture', 'runbook', 'configuration'] → halt: 'Not supported in v1'". SKILL.md Important Notes §1: "Requests for other categories (API-reference, architecture, runbook, configuration) will halt with error listing v1-supported categories." `references/category-taxonomy.md`: API-reference marked "❌ Future". |
| AC-050A-05c | Unknown purpose → halt with error listing valid categories | **PASS** | `execution-procedures.md` Step 1.2: "ELSE → halt: 'Unknown category'". Distinct from 05b (known-but-unsupported vs truly unknown). `references/category-taxonomy.md` §Category Selection Logic: `select_category_v1()` raises error with category name and supported list. The five valid categories are defined in taxonomy table (lines 17–21). |

## Observations

1. **Internal inconsistency — checkpoint folder name:** `SKILL.md` and `execution-procedures.md` consistently use `.x-ipe-checkpoint/`, but `references/handoff-protocol.md` still references the old `.checkpoint/` name. Recommend updating `handoff-protocol.md` to align.
2. **Open-ended format/app_type labels:** SKILL.md §Purpose #2 describes "open-ended source format and application-context labels" with both summary labels and multi-value detections (`source_metadata.detected_formats` / `detected_app_types`). This goes beyond the spec's enumerated values, which is an extensibility improvement — not a regression.
3. **All 19 acceptance criteria pass** against the implementation artifacts. The skill skeleton, input detection heuristics, app-type detection, tool skill loading, category selection, and file-based handoff protocol are all thoroughly documented and procedurally defined.
