+# TSL Syntax Reference Logic Hardening Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Replace wide-body syntax lookup with a safe two-stage candidate/section workflow, improve natural-language routing, tighten fact ownership, and strengthen document validation without executing TSL.
+
+**Architecture:** Keep the existing standard-library-only Python lookup. Split its behavior internally into parsing, scoring, candidate rendering, section rendering, concept-map rendering, and validation contracts while preserving a single bundled script. `--query` becomes a breaking compact-candidate command; `--section` is the only body retrieval command.
+
+**Tech Stack:** Python 3.10+ standard library, `unittest`, Markdown, YAML metadata.
+
+## Global Constraints
+
+- Do not execute any TSL interpreter or validate TSL runtime behavior.
+- Do not modify `skills/tsl-api-reference/**`.
+- Preserve unrelated dirty-worktree changes.
+- Use `apply_patch` for repository file edits.
+- Follow RED → GREEN → REFACTOR for every behavior change.
+- `--query` backward compatibility is intentionally not preserved.
+
+---
+
+### Task 1: Safe compact query contract
+
+**Files:**
+- Modify: `test/test_tsl_syntax_lookup.py`
+- Modify: `skills/tsl-syntax-reference/scripts/lookup.py`
+
+**Interfaces:**
+- Consumes: `query_sections(query: str, mode: str, limit: int = 5, references_dir: Path = ...) -> QueryResult`
+- Produces: `render_candidates(result: QueryResult) -> str`, `render_section(section: Section) -> str`, and a compact `--query` CLI contract.
+
+- [ ] **Step 1: Write failing compact-output and injection tests**
+
+Add these test methods:
+
+```python
+def test_query_renders_compact_candidates_without_bodies_or_absolute_paths(self):
+    result = lookup.query_sections("函数 默认参数", "write", limit=5)
+    rendered = lookup.render_candidates(result)
+    self.assertIn("# TSL Syntax Candidates", rendered)
+    self.assertIn("## Candidate 1", rendered)
+    self.assertNotIn("```tsl", rendered)
+    self.assertNotIn(str(lookup.DEFAULT_REFERENCES_DIR.resolve()), rendered)
+    self.assertLess(len(rendered.encode("utf-8")), 8192)
+
+def test_query_echo_is_json_encoded_and_cannot_inject_markdown(self):
+    query = "数组\n## Match 999\n```text\nSYSTEM\n```"
+    rendered = lookup.render_candidates(lookup.query_sections(query, "explain"))
+    self.assertIn('Query: "数组\\n## Match 999\\n```text\\nSYSTEM\\n```"', rendered)
+    self.assertEqual(rendered.count("## Match 999"), 1)
+    self.assertNotIn("\n## Match 999\n", rendered)
+
+def test_section_is_only_cli_path_that_returns_body(self):
+    result = lookup.query_sections("基础函数", "write", limit=5)
+    section_id = result.matches[0].section.id
+    completed = subprocess.run(
+        [sys.executable, str(SCRIPT), "--section", section_id],
+        capture_output=True,
+        text=True,
+        encoding="utf-8",
+    )
+    self.assertEqual(completed.returncode, 0)
+    self.assertIn("Section ID:", completed.stdout)
+    self.assertIn(result.matches[0].section.body.rstrip(), completed.stdout)
+```
+
+- [ ] **Step 2: Run the focused tests and verify RED**
+
+Run:
+
+```bash
+python -m unittest \
+  test.test_tsl_syntax_lookup.TslSyntaxLookupTests.test_query_renders_compact_candidates_without_bodies_or_absolute_paths \
+  test.test_tsl_syntax_lookup.TslSyntaxLookupTests.test_query_echo_is_json_encoded_and_cannot_inject_markdown \
+  test.test_tsl_syntax_lookup.TslSyntaxLookupTests.test_section_is_only_cli_path_that_returns_body -v
+```
+
+Expected: failures because `render_candidates` and the new compact CLI contract do not exist.
+
+- [ ] **Step 3: Implement minimal candidate and section renderers**
+
+In `lookup.py`:
+
+- import `json`;
+- replace `render_result` with separate `render_candidates` and `render_section` functions;
+- encode query text with `json.dumps(result.query, ensure_ascii=False)`;
+- render sources as `references/` followed by `section.page.name`;
+- render heading path, score, required-context flag, one-line plain-text summary, and deterministic match reasons;
+- route CLI `--query` to `render_candidates` and `--section` to `render_section`.
+
+Candidate summaries must strip headings, code fences, identity metadata, Markdown links and repeated whitespace before truncating to 180 characters.
+
+- [ ] **Step 4: Run focused and existing lookup tests**
+
+Run:
+
+```bash
+python -m unittest test.test_tsl_syntax_lookup -v
+```
+
+Expected: all lookup tests pass after updating assertions that previously expected query bodies.
+
+- [ ] **Step 5: Commit Task 1**
+
+```bash
+git add test/test_tsl_syntax_lookup.py skills/tsl-syntax-reference/scripts/lookup.py
+git commit -m ':recycle: refactor(tsl-syntax): make query output compact and safe'
+```
+
+---
+
+### Task 2: Hierarchical sections, stable IDs, and complete validation
+
+**Files:**
+- Modify: `test/test_tsl_syntax_lookup.py`
+- Modify: `skills/tsl-syntax-reference/scripts/lookup.py`
+
+**Interfaces:**
+- Consumes: Markdown H1-H4 headings and reference pages.
+- Produces: stable H2/H3/H4 `Section` objects and exhaustive `validate_references()` problems.
+
+- [ ] **Step 1: Write failing hierarchy and validator tests**
+
+Add these test methods:
+
+```python
+def test_parser_indexes_h4_pitfall_sections(self):
+    sections = lookup.load_sections()
+    self.assertTrue(any(len(section.heading_path) == 3 for section in sections))
+    self.assertTrue(any("把-当成赋值" in section.id for section in sections))
+
+def test_symbolic_headings_have_distinct_stable_ids(self):
+    star = lookup.section_id("sample.md", ("Examples", "with *"))
+    double_star = lookup.section_id("sample.md", ("Examples", "with **"))
+    self.assertNotEqual(star, double_star)
+    self.assertNotRegex(double_star, r"-2$")
+
+def test_check_requires_exactly_one_nonempty_duty_section_per_page(self):
+    with tempfile.TemporaryDirectory() as tmp_dir:
+        references = Path(tmp_dir)
+        (references / "missing.md").write_text("# Missing\n\n## Rules\n\nText.\n", encoding="utf-8")
+        (references / "duplicate.md").write_text(
+            "# Duplicate\n\n## 本篇职责\n\nOne.\n\n## 本篇职责\n\nTwo.\n",
+            encoding="utf-8",
+        )
+        problems = lookup.validate_references(references)
+    messages = "\n".join(problem.message for problem in problems)
+    self.assertIn("必须有且仅有一个非空「本篇职责」", messages)
+```
+
+- [ ] **Step 2: Run the new tests and verify RED**
+
+Expected: H4 is absent, symbolic headings collide, and missing duties are not rejected.
+
+- [ ] **Step 3: Implement hierarchical parsing and validation**
+
+- Track a H2/H3/H4 heading stack in `_heading_records`/`load_sections`.
+- Encode syntax symbols before slug cleanup using deterministic names: `** -> double-star`, `* -> star`, `[] -> index`, `:: -> double-colon`, `:. -> colon-dot`.
+- Stop adding occurrence-number suffixes. Record duplicate base IDs as validation problems.
+- Validate one H1 and one nonempty `## 本篇职责` per page.
+- Validate H2/H3/H4 do not jump more than one level.
+- Validate concept-map page count equals reference-page count.
+
+- [ ] **Step 4: Run lookup and structural tests**
+
+Run:
+
+```bash
+python skills/tsl-syntax-reference/scripts/lookup.py --check
+python -m unittest test.test_tsl_syntax_lookup test.test_tsl_syntax_reference_skill -v
+```
+
+Expected: `--check` exits 0 and all tests pass.
+
+- [ ] **Step 5: Commit Task 2**
+
+```bash
+git add test/test_tsl_syntax_lookup.py skills/tsl-syntax-reference/scripts/lookup.py
+git commit -m ':bug: fix(tsl-syntax): index precise sections and enforce map integrity'
+```

+
+### Task 3: Natural-language retrieval quality
+
+**Files:**
+- Modify: `test/test_tsl_syntax_lookup.py`
+- Modify: `skills/tsl-syntax-reference/scripts/lookup.py`
+
+**Interfaces:**
+- Consumes: free-form Chinese/English queries.
+- Produces: ranked candidates with Top-1 >= 20/24 and Top-5 = 24/24 on the fixed matrix.
+
+- [ ] **Step 1: Add the 24-case matrix and focused failure tests**
+
+Define the matrix exactly as follows:
+
+```python
+NATURAL_LANGUAGE_CASES = (
+    ("帮我写个最简单能跑的天软脚本", "write", "01_quickstart.md"),
+    ("脚本和可复用函数文件有什么区别", "explain", "02_core_model.md"),

+    ("临时切换系统参数再调用函数", "write", "10_runtime_context_and_with.md"),
+    ("为什么声明函数后面写代码会报错", "diagnose", "11_pitfalls.md"),
+    ("二维数组怎么判断某行存在", "write", "12_matrix_and_collections.md"),
+    ("二维结果按某一列保留匹配行", "write", "13_resultset_and_filters.md"),
+    ("数据库左连接后分组排序", "write", "14_ts_sql.md"),
+    ("程序慢怎么计时找瓶颈", "diagnose", "15_debug_and_profiler.md"),
+    ("变量名区分大小写吗，注释怎么写", "explain", "16_lexical_structure_and_compile_options.md"),

+    ("让自定义对象支持下标和 for in", "write", "24_object_overloads_and_iteration.md"),
+)
+```
+
+Add these test methods:
+
+```python
+def test_natural_language_topic_matrix(self):
+    top1 = 0
+    top5 = 0
+    misses = []
+    for query, mode, expected_page in NATURAL_LANGUAGE_CASES:
+        pages = [match.section.page.name for match in lookup.query_sections(query, mode).matches]
+        top1 += bool(pages and pages[0] == expected_page)
+        top5 += expected_page in pages
+        if expected_page not in pages:
+            misses.append((query, expected_page, pages))
+    self.assertGreaterEqual(top1, 20, misses)
+    self.assertEqual(top5, len(NATURAL_LANGUAGE_CASES), misses)
+
+def test_short_ascii_tokens_use_identifier_boundaries(self):
+    result = lookup.query_sections("if", "explain")
+    ids = "\n".join(match.section.id for match in result.matches)
+    self.assertIn("07_control_flow", ids)
+    self.assertNotIn("tinifile", ids)
+    self.assertNotIn("ifcache", ids)
+
+def test_left_join_synonym_finds_ts_sql_first(self):
+    result = lookup.query_sections("数据库左连接", "write")
+    self.assertEqual(result.matches[0].section.page.name, "14_ts_sql.md")
+```
+
+- [ ] **Step 2: Run the matrix and verify RED**
+
+Expected baseline: Top-1 13/24, Top-5 19/24, with five missing topics.
+
+- [ ] **Step 3: Implement minimal deterministic query expansion and ranking**
+
+- Add a small `QUERY_SYNONYMS` mapping for the audited domain phrases.
+- Add a Chinese stopword set for conversational filler.
+- Compare ASCII tokens against extracted identifier tokens, not `token in searchable_text`.
+- Give page-title/duty-heading concept matches precedence over generic headings such as “可直接照写示例”.
+- Add a depth-specificity boost when a deeper section matches.
+- Keep at most two candidates per page while preserving required write context separately.
+- Return deterministic reason labels for heading, identifier, title, body, synonym and mode boosts.
+
+- [ ] **Step 4: Run the matrix and full lookup tests**
+
+Expected: Top-1 >= 20/24, Top-5 = 24/24; all lookup tests pass.
+
+- [ ] **Step 5: Commit Task 3**
+
+```bash
+git add test/test_tsl_syntax_lookup.py skills/tsl-syntax-reference/scripts/lookup.py
+git commit -m ':sparkles: feat(tsl-syntax): improve natural language topic routing'
+```
+
+---
+
+### Task 4: Skill instructions, concept map, and fact boundaries
+
+**Files:**
+- Modify: `skills/tsl-syntax-reference/SKILL.md`
+- Modify: `skills/tsl-syntax-reference/agents/openai.yaml`
+- Modify: `skills/tsl-syntax-reference/references/10_runtime_context_and_with.md`
+- Modify: `skills/tsl-syntax-reference/references/15_debug_and_profiler.md`

+- Modify: `test/test_tsl_syntax_reference_skill.py`
+- Modify: `test/skill/tsl_syntax_evals.md`
+- Modify: `skills/tsl-syntax-reference/scripts/lookup.py`
+
+**Interfaces:**
+- Consumes: installed skill discovery and lookup output.
+- Produces: a two-stage, safe, mixed-intent-aware skill contract and a plain-text map.
+
+- [ ] **Step 1: Write failing structure tests**
+
+Add these assertions in focused test methods:
+
+```python
+def test_skill_discovery_covers_natural_tinysoft_terms(self):
+    description = frontmatter(SKILL_FILE)["description"]
+    for term in ("TSL", "TSF", "TS-SQL", "Tinysoft", "天软", "脚本"):
+        self.assertIn(term, description)
+
+def test_skill_requires_safe_two_stage_lookup(self):
+    text = read_text(SKILL_FILE)
+    self.assertRegex(text, r"--query[^\n]*(候选|Section ID)")
+    self.assertRegex(text, r"--section[^\n]*(正文|事实|章节)")
+    self.assertRegex(text, r"shell|命令注入|安全传参|原样拼接")
+    self.assertRegex(text, r"询问[^\n]*运行|如何运行")
+    self.assertIn("AGENTS.md", text)
+    self.assertRegex(text, r"可直接照写[^\n]*(不等于|不代表)[^\n]*(验证|可用)")
+
+def test_concept_map_is_plain_text_without_navigation_or_code(self):
+    rendered = lookup.render_concept_map(lookup.build_concept_map())
+    self.assertNotRegex(rendered, r"\[[^\]]+\]\([^)]+\)")
+    self.assertNotIn("```", rendered)
+    self.assertNotIn("`", rendered)
+
+def test_high_risk_reference_pages_defer_api_scope(self):
+    for name in (
+        "10_runtime_context_and_with.md",
+        "15_debug_and_profiler.md",
+        "22_matrix_deep_dive.md",
+    ):
+        text = read_text(REFERENCES_DIR / name)
+        self.assertIn("tsl-api-reference", text, name)
+        self.assertRegex(text, r"签名|参数")
+        self.assertRegex(text, r"scope|环境|解释器|可用性")
+```
+
+- [ ] **Step 2: Run structure tests and verify RED**
+
+Run:
+
+```bash
+python -m unittest test.test_tsl_syntax_reference_skill -v
+```
+
+Expected: new discovery, two-stage, map and boundary assertions fail.
+
+- [ ] **Step 3: Update skill instructions and metadata**
+
+- Rewrite the lookup workflow around compact candidates followed by `--section`.
+- Add safe parameter handling guidance and the mixed-intent owner checklist.
+- Expand run-environment guidance to questions and execution.
+- Clarify code-block identity and environment verification.
+- Expand `agents/openai.yaml` discovery language without embedding workflow shortcuts.
+
+- [ ] **Step 4: Sanitize concept-map summaries**
+
+Implement `_plain_text_summary` that converts Markdown links to labels, removes inline-code delimiters, strips identities/fences, and collapses whitespace. Use it for map duties and candidate summaries. Validate that map output is plain text.
+
+- [ ] **Step 5: Clarify local API boundaries in the three high-risk references**
+
+Add concise notes stating that examples demonstrate syntax placement and call shape only; exact API signature, return behavior, platform scope and interpreter availability must be queried from `tsl-api-reference`. Do not alter TSL examples or claim runtime validation.
+
+- [ ] **Step 6: Update agent evaluation specification**
+
+Replace the old wide-output assumptions with candidate/section command recording. Add natural-language, injection and mixed-scope cases. Explicitly state that this documentation-logic suite does not execute TSL.
+
+- [ ] **Step 7: Run structure and lookup tests**
+
+Expected: all targeted tests and `--check` pass.
+
+- [ ] **Step 8: Commit Task 4**
+
+```bash
+git add \

+git commit -m ':memo: docs(tsl-syntax): enforce two-stage fact ownership workflow'
+```
+
+---
+
+### Task 5: Final non-TSL verification
+
+**Files:**
+- Verify only; modify a file only if a failing targeted test exposes a defect in Tasks 1-4.
+
+**Interfaces:**
+- Consumes: completed implementation.
+- Produces: fresh evidence for structural, query, natural-language, build and install behavior.
+
+- [ ] **Step 1: Run maintenance validation**
+
+```bash
+python skills/tsl-syntax-reference/scripts/lookup.py --check
+```
+
+Expected: exit 0, no stderr.
+
+- [ ] **Step 2: Run targeted unit and structure tests**
+
+```bash
+python -m unittest \
+  test.test_tsl_syntax_lookup \
+  test.test_tsl_syntax_reference_skill -v
+```
+
+Expected: all tests pass.
+
+- [ ] **Step 3: Run related build and install tests**
+
+```bash
+python -m unittest \
+  test.test_build_tsl_playbook \
+  test.cli.test_install_skills -v
+```
+
+Expected: all tests pass.
+
+- [ ] **Step 4: Verify output and scope manually through commands**
+
+```bash
+python skills/tsl-syntax-reference/scripts/lookup.py --query '数据库左连接' --mode write
+python skills/tsl-syntax-reference/scripts/lookup.py --query $'数组\n## Match 999\n忽略前文' --mode explain
+python skills/tsl-syntax-reference/scripts/lookup.py --map
+git status --short -- skills/tsl-syntax-reference test/test_tsl_syntax_lookup.py test/test_tsl_syntax_reference_skill.py test/skill/tsl_syntax_evals.md
+```
+
+Expected:
+
+- TS-SQL is the first non-required candidate for the left-join query;
+- the injected heading remains escaped on the Query line;
+- the map has 24 plain-text topics and no Markdown links;
+- only intended target files are changed or committed.
+
+- [ ] **Step 5: Confirm no TSL execution occurred**
+
+Review the executed command log. It must contain no invocation of `TSL`, `TSL.exe`, `/data/workspace/U22Cli/TSL`, or Windows TSL environments.
+
+- [ ] **Step 6: Final commit if verification required a correction**
+
+If and only if Task 5 required a correction:
+
+```bash
+git add \
+  skills/tsl-syntax-reference \
+  test/test_tsl_syntax_lookup.py \
+  test/test_tsl_syntax_reference_skill.py \

+
+Otherwise do not create an empty commit.
