Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

lockedin-render-jaso scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.

render-jaso

Research-based calibration. RUBRIC.md ships with five dimensions and score bands. prompt-writer.md, prompt-reviewer.md, and banned_phrases.json (28 cross-source-confirmed entries) all ship.

Use this when

  • User names a Korean company and asks to write a 자소서.
  • User points at a 자소서 question (e.g., 지원동기 / 성장과정 / 성격의 장단점 / 입사 후 포부).
  • User asks to "polish my 자소서" against the rubric.

Do NOT use when

  • User wants an English resume → use render-resume-en.
  • The vault is empty (no ontology nodes to quote) → seed first via /lockedin init or lockedin init --fixture FILE.

Required design constraints (locked)

  1. 두괄식 — conclusion / 핵심 / 차별점 in the first paragraph; the rest of the answer scaffolds the lead.
  2. 구조화된 문맥 — within Korean 4-question convention (지원동기 / 성장과정 / 성격의 장단점 / 입사 후 포부 etc.), use STAR or PAR per paragraph.
  3. 두루뭉술한 표현 제거 — banned-phrase regex check runs before the reviewer rubric pass. See banned_phrases.json.
  4. 초개인화된 경험 기반 — every claim quotes a concrete ontology node by slug (e.g., [[role/lead-pm-fintech-2024]]). Vague generalities cost the 구체성 dimension.
  5. 회사·직무 fit — query the ontology for nodes with edges to the target company / 직무 / industry; surface the top-3 most relevant before drafting.

Two-turn writer/reviewer pattern

Run as two separate Claude turns:

  1. Writer turn — produce the 자소서 draft. Quote ontology slugs. Apply banned-phrase filter to the draft.
  2. Reviewer turn — clear the writer context. Re-load RUBRIC.md fresh. Score on 두괄식 / 구조화 / 구체성 / 표현 / 적합성 (0–5 each). Emit JSON. If any dimension < 4 OR revisions_required: true, return to the writer turn once with the review notes.

Same-turn self-evaluation inflates scores by ~1 point. Do not skip the separation.

Final checklist

  • Banned-phrase regex pass ran (and was clean) before rubric.
  • Reviewer turn was a separate Claude context with fresh RUBRIC.md load.
  • Output JSON has all 5 dimensions ≥ 4 (or one revise cycle ran).
  • Concrete ontology slugs are quoted in the rendered text.

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
