paper-search-pro: Instructions file for Claude Code

CLAUDE.md

paper-search-pro CLAUDE.md is an instructions file for Claude Code from O0000-code/paper-search-pro. It costs 1,067 tokens per session, scanned A, original, Apache-2.0.

A repository instruction file for the paper-search-pro project, documenting rules that coding agents must preserve, such as naming, data handling, user workflows, and build behavior.

In plain words
What is it for?
Use it when modifying paper-search-pro, especially when working on journal rankings, source fetching, agent features, or the HTML report build.
Why use it?
It gives agents the project-specific constraints they need before changing code, reducing the risk of breaking established behavior or using incorrect research-metric terms.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

This is O0000-code/paper-search-pro's own configuration. It tells Claude Code how to work on paper-search-pro itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything paper-search-pro configures →

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

paper-search-pro CLAUDE.md 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 1mo ago.

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.

paper-search-pro — notes for sessions modifying this repo

Published Agent Skill (Apache 2.0). Edit the git repo here; the running copy is separate at ~/.claude/skills/paper-search-pro/ — sync to it (rsync scripts/ references/ assets/ + SKILL.md) for changes to take effect.

Invariants — do not break

  • R-04 naming: OpenAlex / SJR / 中科院(CAS) journal metrics are partitions / open impact, never "Impact Factor". Only JCR IF(YYYY) is a real Impact Factor.
  • R-19 human-path preservation: the human 14-STEP flow — especially STEP 6 (parallel classification SubAgents) and STEP 12 (HTML render) — must stay byte-identical when the agent/headless, source-switch, and journal-rank features are unused. Every new capability is opt-in additive; default = current behavior.
  • Journal-rank data is never committed (Clarivate/SCImago/CAS copyright). It is runtime-fetched from public GitHub mirrors into ~/.paper-search-pro/ranks/. scripts/journal_rank.py is the single canonical rank layer; scripts/sjr_helper.py is superseded (kept for back-compat, not the wired source).
  • Zero new hard dependencies for v2.2 (GitHub-raw fetch uses requests) — keep it that way: no playwright, no heavyweight libs.
  • One coverage estimator: scripts/discovery_curve.py (sample coverage over the run's raw/ retrieval files, bootstrap interval, labelled prior fallback). data_materialization only renders it — never add a second fit there: an improvised τ=80 fallback once became the only path and showed ~99% on every run.
  • Only relevance ranking may use OpenAlex's full-text search=: any other sort (citations, date) matches title_and_abstract.search — full-text matches ranked by citations or date were mostly off-topic (0–8 / 0–24 of 50 on topic across 8 topics, 2026-09-30). The recent layer is relevance within a date window (run_leg("recent")), never "newest first". tests/test_recency_legs.py goes red if either is undone.
  • No evidence never reads as high coverage: the estimator is exactly 1 when it has no singletons to go on (Q1 = 0, or Q1 = 1 and Q2 = 0), so that result is not used — the rcs ≥ 6 band is tried, then the prior capped at 50%. A 100% once stopped a Standard run with two core papers before its citation hop. The design record (history, Undermind, why sample coverage) is outside the repo: ~/Documents/Claude Code/Skills/Enhancement/Paper Search Pro/coverage-estimator/00_design_record.md.

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.
