collect-jd

collect-jd

Canonical principle: Verification stage MUST be on the canonical path. No bypass routes. Every discovered URL goes through the same flow; "fast paths" that skip verification are forbidden.

Dedicated skill for JD collection, curation, and organization. Specific rules are added through Phase B pressure scenario cycles (TDD RED-GREEN-REFACTOR).

Scope Boundary

• collect-jd: JD discovery · collection · curation · organization (this skill)
• resume-apply: skill that consumes already-recorded JDs (this skill does not participate)
• review-resume: resume review (this skill does not participate)
• resume-forge: resume material mining (this skill does not participate)

MANDATORY: Gate Task Creation

Gate Task Creation (MANDATORY) — at skill invocation start, pre-create 8 named gate tasks via TaskCreate. Each task is the source of truth for gate completion; the per-source ledger is the source of truth for per-item progress.

→ Details: [reference/bootstrap.md](reference/bootstrap.md#gate-task-creation)

State Location

All state under $OMT_DIR/collect-jd/ only. $OMT_DIR is read from the environment; this skill must not compute it directly. If $OMT_DIR is unset, abort + recovery guidance — global fallback forbidden. Forbidden Paths: ~/.omt/global/**, ~/.omt/<other-project>/collect-jd/**, /tmp/**, and any absolute path outside $OMT_DIR.

→ Details (rejection protocol, rationalization loopholes): [reference/bootstrap.md#state-location--forbidden-paths](reference/bootstrap.md#state-location--forbidden-paths)

Session Lock (MANDATORY)

Session Lock (MANDATORY) — atomic .lock file with PID + liveness check (kill -0); single-writer per session. Acquire at Gate 1, release at Gate 8 (after Coverage Gate passes).

→ Details: [reference/bootstrap.md](reference/bootstrap.md#session-lock)

Storage Backend Interview (MANDATORY)

Storage Backend Interview (MANDATORY) — on first run, AskUserQuestion is mandatory to collect platform + how. Silent default to filesystem is forbidden.

→ Details: [reference/bootstrap.md](reference/bootstrap.md#storage-backend-interview)

Atomic Write Pattern (MANDATORY)

Atomic Write Pattern (MANDATORY) — .tmp → fsync → rename for all single-file writes; never partial overwrites. Mandatory at JD file persist, sources.yaml updates, and seen.jsonl appends.

→ Details: [reference/bootstrap.md](reference/bootstrap.md#atomic-write-pattern)

Ingest Paths (5)

1. Direct URL input
2. Text paste
3. File or folder path
4. Company name (only within sites registered in sources.yaml)
5. Batch rescan ("싹 돌려")

Before each Ingest Path execution, Phase 0 profile interview + Dedup L1/L2 must be performed without exception.

Sources Registration (MANDATORY)

At session start, load $OMT_DIR/collect-jd/sources.yaml. If empty or absent, propose via a single AskUserQuestion: "Do you have JD source sites to register?" (skippable — not as mandatory as Profile Interview). When user provides a URL, atomic append with {slug, name, careers_url, added_at, pagination, crawl_state, ingest} structure.

Source-level Ingest Config (ingest): schema = {detail_required_before_persist: bool}. Default false. When true, the source's Full Coverage Ingest Protocol MUST run Tier 2 (detail body fetch) for every JD before persist — Tier 1 immediate persist is FORBIDDEN. See [Full Coverage Ingest Protocol](#full-coverage-ingest-protocol-mandatory-3-tier).

Reusable Crawl: When user utterance contains trigger phrases "오늘 돌려" / "싹 돌려" / "전체 재크롤" / "sources 돌려" etc. → iterate all registered sources → perform Listing Pagination per source → per-JD L1 evaluation (Algorithm B) + Dedup Gate + Classify + Persist. No automatic scheduling.

CRITICAL: Open-web free crawl when sources.yaml is empty is forbidden. Even on user "싹 돌려" utterance, if source count is 0, report "등록된 소스가 없어요" and prompt registration.

→ Details: [reference/dedup-and-discovery.md#sources-registration](reference/dedup-and-discovery.md#sources-registration)

Listing Pagination (MANDATORY, single-path)

Single source of truth: pagination.how. All listing discovery — first-time auto-detect, user-interview fallback, cached re-execution, invalidation re-interview — collapses into one algorithm discover_listing(source).

Algorithm:

1. If pagination.how absent → try Tier A 9-pattern catalog → success: serialize as how={origin: auto, pattern, params}. fail: AskUserQuestion → how={origin: interview, pattern, params, prose}.
2. Execute pagination.how.
3. On execution failure → invalidate per trigger table (transient: 1-retry; structural: immediate). Push current how to previous_how 3-slot ring → AskUserQuestion 3-option (new method / Tier A retry / skip). On retry-fail → raise (silent empty forbidden).

Schema: pagination.how = { origin: auto|interview, pattern: <13-enum>, params: {}, prose: <free-form> }. previous_how: [] inline ring (LRU, max 3). invalidated_at: null ISO timestamp.

CRITICAL:

• First-run discovery skipping Tier A 9-pattern catalog → AskUserQuestion shortcut forbidden.
• discover_listing returning empty [] on execution failure forbidden — must raise; caller skip-with-audit, no Per-Site Memory false-clean.
• Coverage Verification fires after was_invalidated: false (success path) only. raise → skip Coverage + Per-Site Memory update.

→ Details (γ schema, 13-pattern catalog, invalidation trigger table, previous_how ring, raise-on-failure contract, 2 new loopholes): [reference/dedup-and-discovery.md#listing-pagination](reference/dedup-and-discovery.md#listing-pagination)

Listing Pagination Coverage Verification (MANDATORY, 3-check)

Coverage Verification (MANDATORY, 3-check) — declared-total match, scroll stability, infinite-scroll absence. Without coverage_proof, batch_run_completed=true is forbidden.

→ Details: [reference/dedup-and-discovery.md](reference/dedup-and-discovery.md#listing-pagination-coverage-verification)

Per-Site Crawl Memory (MANDATORY)

Maintain per-source crawl memory in sources.yaml.<source>.crawl_state (3 sub-groups) and $OMT_DIR/collect-jd/crawl_state/<source>/seen.jsonl (append-only file).

Storage layout:

• $OMT_DIR/collect-jd/crawl_state/<source>/seen.jsonl — one JSON object per line, each < 1 KB. Append via POSIX open(path, 'a'). Session-lock guarantees single-writer.
• Line schema: {"id": "...", "url": "...", "processed_at": "<ISO8601>", "verdict": "included|excluded|ambiguous", "role_title": "..."}
• The id field is a deterministic key derived from the per-site identifier_kind strategy — NOT an auto-generated UUID.

Per-Site Crawl Memory schema (sources.yaml <source>.crawl_state sub-keys + seen.jsonl line schema): see [reference/dedup-and-discovery.md](reference/dedup-and-discovery.md#per-site-crawl-memory) — do not restate inline.

Each source records its id extraction strategy in sources.yaml.<source>.crawl_state.seen via two fields: identifier_kind (strategy enum) + identifier_extractor (param name for id_query, null for url, hash spec for fingerprint).

Re-crawl algorithm (Algorithm B canonical): every discovered URL → L1 → 1 of 4 terminal states (new_ingest|touch_only|ttl_recheck|manual_skip). seen.jsonl is audit/lookup index, NOT a pre-L1 exclusion gate. Drift detection (seen_hit + L1_miss / L1_hit + seen_miss) is mandatory.

→ Details: [reference/dedup-and-discovery.md](reference/dedup-and-discovery.md#per-site-crawl-memory)

Per-Source Ledger (MANDATORY)

One ledger file per source per session, used by Coverage Gate (Gate 8). Without it, Gate 8 cannot pass. The row schema, lifecycle (Gates 4-7), and Coverage Gate algorithm are defined canonically in dedup-and-discovery.md.

→ Details: [reference/dedup-and-discovery.md](reference/dedup-and-discovery.md#per-source-ledger)

Detail Split Auto Fan-out (MANDATORY)

Detail Split Auto Fan-out — when a posting page advertises N positions in a single anchor, split into N separate JD files with parent_url + sub_position (presence-coupled).

team-level granularity도 의무. body에 subsidiary 산하 team labels 명시 시 subsidiary × team 단위로 fan-out, sub_position = '<subsidiary> / <team>' format 사용. 단일 단어 stack tag(Kotlin 등)는 team label이 아님.

→ Details: [reference/ingest-and-curation.md](reference/ingest-and-curation.md#detail-split-auto-fan-out)

Identifier Kind Heuristic (MANDATORY)

Identifier Kind Heuristic (MANDATORY on first source registration) — choose id_query / url / fingerprint based on URL pattern; silent default forbidden.

→ Details: [reference/dedup-and-discovery.md](reference/dedup-and-discovery.md#identifier-kind-heuristic)

Phase 0: Profile Interview Required (MANDATORY)

When $OMT_DIR/collect-jd/profile/profile.yaml is absent, a minimum 3-round profile interview (AskUserQuestion) is required before JD collection. Round 1: career history, years of experience, preferred domains. Round 2: tech stack, strengths. Round 3: company, salary, location, remote work, exclude preferences. After the interview, atomic write profile.yaml (includes version: 1 field). If profile exists, proceed to normal collection. 5 rationalization patterns blocked — urgency, being in a hurry, or having received a URL are none of them valid reasons to skip the interview.

→ Details (rationalization loopholes, purpose explanation): [reference/bootstrap.md#phase-0-profile-interview-required](reference/bootstrap.md#phase-0-profile-interview-required)

Dedup (L1 URL-only + L2 LLM similarity)

Run dedup in L1 → L2 order before writing a new JD file (MANDATORY).

CRITICAL — Dedup Check Gate rules:

• Even if jobs/ is empty, the L1 gate must be recorded as executed. "Skip because jobs is empty" is forbidden — trivial-pass must not be silently processed; must be explicitly logged as "L1 gate executed: 0 candidates".
• Even when L2 conditions are not met (0 JDs for the same company_slug), record "L2 gate evaluated: not applicable" in audit.
• Saving without running the dedup gate is forbidden. If fingerprint_check field is empty, reject the save.

→ Dedup Gate Enforcement details: [reference/dedup-and-discovery.md#dedup-check-gate-enforcement](reference/dedup-and-discovery.md#dedup-check-gate-enforcement)

L1 / L2 Dedup (MANDATORY) — L1 = URL-only normalize match (single-key gate). L2 = LLM similarity check on L1 miss with same company_slug OR L1 hit + TTL exceeded. L2 outcomes (same:true|false) and persist actions are spec'd canonically in dedup-and-discovery.md.

→ Details: [reference/dedup-and-discovery.md](reference/dedup-and-discovery.md#dedup-layer-1) + [reference/dedup-and-discovery.md](reference/dedup-and-discovery.md#dedup-layer-2) → Flow diagram (L1→L2 decision tree): [reference/dedup-and-discovery.md#decision-flow](reference/dedup-and-discovery.md#decision-flow)

Matching Loop (history → rules → filter) (MANDATORY)

3-phase verdict against profile/rules.yaml before saving each JD.

• Phase 1: If same URL/slug pair exists in jobs/**/*.md → inherit status. Otherwise proceed to Phase 2.
• Phase 2: Pinned prompt reference/ambiguity-prompt.md, temperature 0. match → status: included (auto). mismatch → status: excluded (auto, Exclude Flow rules apply). ambiguous → auto-verdict forbidden; must proceed to Phase 3.
• Phase 3: AskUserQuestion — Korean question based on missing_signals. Options: include / exclude / defer. Call immediately even in Batch mode, no queuing.
• Auto-decision audit trail: on auto-save, record auto:<verdict>:<rules.yaml sha256 short 8> in reason_note.

Note: Matching Loop is the verdict algorithm invoked inside each Full Coverage tier.

→ Details (rationalization loopholes, counterexample): [reference/ingest-and-curation.md#matching-loop](reference/ingest-and-curation.md#matching-loop) → Flow diagram (Phase 1→2→3 decision tree): [reference/dedup-and-discovery.md#decision-flow](reference/dedup-and-discovery.md#decision-flow)

Full Coverage Ingest Protocol (MANDATORY, 3-tier)

Note: Full Coverage is the input-depth escalation ladder; Matching Loop runs inside each tier.

Process all JDs discovered from listing scrape without omission. Escalate in order from information exposed on the discovery screen.

• Tier 1 — Listing Metadata Resolution: Extract role_tags from anchor.innerText in full (title + stack label + subsidiary badge, etc.) → immediately persist when a single rules.yaml rule triggers. Reading only the title is forbidden.

Tier 1 Eligibility (MANDATORY): Tier 1 immediate persist is allowed ONLY when sources.yaml.<source>.ingest.detail_required_before_persist: false (or absent — default false). When true, Tier 1 is FORBIDDEN: every JD MUST escalate to Tier 2 detail fetch before persist, and Detail Split Auto Fan-out check MUST run on the body. This eliminates the operational gap where multi-subsidiary or multi-position JDs would be silently saved as a single record without fan-out detection.

Why source-level (not per-JD heuristic): Listing-level signals (e.g., "외 N개 계열사" suffix) cannot reliably detect body-only fan-out signals. The per-source declarative config is the canonical decision point — uniform within a source, no runtime branching per JD.

• Tier 2 — Detail Fetch Verification: MANDATORY escalation when Tier 1 is ambiguous. Playwright browser_navigate → extract body → re-judge. Persist when judgment is clear.
• Tier 3 — User Interview: MANDATORY AskUserQuestion when ambiguity persists after Tier 2 (Korean question based on missing_signals, options: include/exclude/defer).

CRITICAL:

• Obligation to obtain full anchor.innerText. Parsing only the title and ignoring stack labels is forbidden.
• Silent skip at tier boundaries is forbidden: pending dump when Tier 1 is ambiguous is forbidden; pending dump when Tier 2 is ambiguous is forbidden.
• Declaring batch_run_completed=true when processed_count < discovered_count is forbidden. Record batch_run_completed=false + pending_count=<N>.
• T11 real violation: Toss Server Developer #197 — listing innerText contained "Kotlin · Java · Spring · Backend" → should have been an immediate match rule trigger for rules.yaml match rule #1, but was missed due to title-only parsing.

→ Details (Tier 1/2/3 spec, decision flow chart, rationalization loopholes, counterexample): [reference/ingest-and-curation.md#full-coverage-ingest-protocol](reference/ingest-and-curation.md#full-coverage-ingest-protocol)

Exclude Flow (tags + reason_note MANDATORY)

When saving with status: excluded, simultaneously required: tags: [...] (minimum 1, tags.yaml emergent slug) + reason_note (verbatim user utterance, empty string forbidden). If missing, trigger Emergent tag interview before save: (1) collect reason (2) derive tag (top-3 candidates or new slug) (3) update tags.yaml (4) atomic write. This flow does NOT apply to included / ambiguous / pending.

→ Details (emergent tag interview, tags.yaml schema, loopholes, counterexample): [reference/ingest-and-curation.md#exclude-flow](reference/ingest-and-curation.md#exclude-flow)

Reversal (status change record) (MANDATORY)

When changing an existing file's status, prepend prev: <prev_status> @ <ISO8601 date> at the top of reason_note. Atomic write (.tmp → rename). Multiple reversals accumulate (prepend repeatedly; topmost = most recent). On rules re-evaluation: append (rules_reeval:<sha short 8>) suffix. No exceptions: first save · L1 last_checked_at update · L2 fingerprint_check update.

→ Details (rationalization loopholes): [reference/ingest-and-curation.md#reversal](reference/ingest-and-curation.md#reversal)

Manual Edit Safety

Batch rescan will never overwrite files whose frontmatter the user has manually edited. If any of the detection signals match (future last_checked_at · canonical contract violation [non-standard field OR value outside enum]), skip that file + add 수동 편집 감지: N건 line to the report.

→ Details: [reference/ingest-and-curation.md#manual-edit-safety](reference/ingest-and-curation.md#manual-edit-safety)

Ingest Validation

Before WebFetch · file · text ingest, check body length (< 200 chars) and stop signals only (login/captcha/403, etc.). On failure: save forbidden + report "유효 JD 아닌 것으로 보임" error + record to $OMT_DIR/collect-jd/ingest-failures.log.

Use the insane-search skill for WebFetch.

→ Details: [reference/ingest-and-curation.md#ingest-validation](reference/ingest-and-curation.md#ingest-validation)

Batch Mode Report Schema (MANDATORY)

On batch rescan completion, the last line of the response must exactly match this regex:

^신규: \d+건, 기존: \d+건, 업데이트: \d+건$

Zero counts must not be omitted. Format variations are forbidden. Record only actual aggregate results.

→ Details (definitions, examples, forbidden patterns, loopholes): [reference/ingest-and-curation.md#batch-mode-report-schema](reference/ingest-and-curation.md#batch-mode-report-schema)

Role Tagging (MANDATORY)

Two fields required when saving a JD: role_title_verbatim (verbatim original title, no modification) + role_tags: [...] (LLM call, subset of taxonomy.yaml enum, temperature 0). Korean synonyms (백엔드/서버개발자/서버사이드) must include backend. On JSON parse failure: retry once; on 2nd failure, report error (saving empty array is forbidden).

→ Details (taxonomy baseline, LLM invocation contract, pinned prompt, loopholes, counterexample): [reference/ingest-and-curation.md#role-tagging](reference/ingest-and-curation.md#role-tagging)

YAML Robustness

On parse failure for any state YAML (profile/taxonomy/rules/tags/sources/config): no crash. Copy original to <file>.bak.<ISO8601> once → AskUserQuestion with 2 options (edit manually [default] / reset to default [data loss warning]). Automatic deletion or cleanup of user data is forbidden.

→ Details: [reference/ingest-and-curation.md#yaml-robustness](reference/ingest-and-curation.md#yaml-robustness)

Company-Name Ingest

Ingest path #4 (company name only) operates only within sites registered in sources.yaml. For unregistered companies → WebFetch/open-web search is absolutely forbidden; trigger AskUserQuestion with "공식 채용 페이지 URL 을 알려주세요". When user provides a URL, append to sources.yaml then proceed with standard flow. Blacklist supported.

→ Details: [reference/dedup-and-discovery.md#company-name-ingest](reference/dedup-and-discovery.md#company-name-ingest)

Rules Re-evaluation

Re-derive rules.yaml based on today's collection results. Trigger phrases: "오늘 수집 정리해줘" / "오늘 본 JD로 규칙 업데이트" / "규칙 재평가" / "rules 다시 뽑아줘" / auto-propose when 1 or more include·exclude occur within a session. Scope: only JD files where the date portion of last_checked_at is today (excluding manual-edited files). Workflow: (1) load scope + store rules.yaml.sha256.before in memory (2) LLM call (temperature 0) → generate proposed rules (3) atomic write rules.yaml.proposed (.tmp → rename, includes version:1 + _proposed_at + _based_on) (4) display diff + AskUserQuestion (approve / reject / edit manually) (5) on approve, race check required: recompute sha256 of rules.yaml → if mismatch with before, abort (6) race OK → overwrite rules.yaml (atomic write, excluding _proposed_at/_based_on) + remove .proposed. If 0 JDs today, stop immediately. Overwriting rules.yaml directly without approve is forbidden.

→ Details: [reference/ingest-and-curation.md#rules-re-evaluation](reference/ingest-and-curation.md#rules-re-evaluation)
