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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00045 | $0.00904 |
| Opus 5 | $0.00023 | $0.00452 |
| Sonnet 5 | $0.00009 | $0.00181 |
| Haiku 4.5 | $0.00005 | $0.00090 |
Grade A, and why
jscpd 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 — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.
jscpd
Copy-paste detector for source code. Use this skill to run jscpd against packages/* in this repo and understand its output before handing clones to dry-refactoring.
Not to be confused with
packages/hr-skills-build/src/server/validation/detect-duplicates.ts, which detects duplicated HR skill content (skills/hr-*/SKILL.md) at publish time.jscpdhere targets TypeScript source code inpackages/*only — keep the two concerns separate and never merge their logic.
Quick start
This repo uses Bun, so prefer bunx over npx:
# Scope to the TypeScript packages only — skip skills/ (markdown) and generated output
bunx jscpd@5 packages \
--format typescript \
--mode strict \
--min-lines 3 \
--min-tokens 20 \
--reporters console,json,markdown \
--output duplicate-report \
--ignore "**/node_modules/**,**/dist/**,**/*.md"
# Compact output optimized for agents
bunx jscpd@5 packages --reporters ai --format typescript
duplicate-report/ is a generated artifact — do not commit it; add it to .gitignore if it isn't already covered.
AI reporter output format
The ai reporter produces compact, token-efficient output:
Clones:
packages/hr-skills-build/src/server/validation/validate.ts:53-59 ~
security.ts:89-94
---
N clones · X% duplication
- Same directory: shared path prefix factored out
- Different paths: full path shown for both sides
Options used in this repo
| Option | Value here | Why |
|---|---|---|
--format typescript |
scoped to .ts |
skills/**/*.md content duplication is handled by detect-duplicates.ts, not jscpd |
--mode strict |
exact-match clones | avoids false positives from formatting-only similarity (Biome already normalizes formatting) |
--min-lines 3 / --min-tokens 20 |
low thresholds | this is a small, young codebase; catch clones early before they compound |
--ignore |
node_modules, dist, *.md |
matches .gitignore / build output conventions |
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.

jscpd is a skill published in the GitHub repository tuanductran/hr-skills (57 stars, last pushed today), licensed MIT. It adds 45 tokens to every session and 904 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
