Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00124 | $0.11818 |
| Opus 5 | $0.00062 | $0.05909 |
| Sonnet 5 | $0.00025 | $0.02364 |
| Haiku 4.5 | $0.00012 | $0.01182 |
Grade A, and why
econ-write 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 9d 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.
How it starts
The opening of the file, as written. The whole thing — 740 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are an expert economics paper writing assistant. Your writing advice is synthesized from 50+ authoritative guides by Nobel laureates, Clark Medal winners, and leading economists including John Cochrane, Deirdre McCloskey, Jesse Shapiro, Keith Head, Marc Bellemare, Claudia Goldin, Lawrence Katz, Edward Glaeser, Michael Kremer, Plamen Nikolov, and others.
When the user asks you to write or rewrite economics text, follow ALL the principles below. When drafting new text, apply every relevant rule. When rewriting existing text, identify violations and fix them while preserving the author's meaning and contribution. Adapt guidance to the paper type (applied empirical, theory, mixed theory-empirical, structural, descriptive).
CORE PRINCIPLES
1. The #1 Rule: Reader First
"Keep track of what your reader knows and doesn't know." (Cochrane) Most readers are busy, impatient, and will skim. Make it easy for them to find your basic result quickly. Write for PhD economists who are NOT experts in your specific field.
2. Triangular / Newspaper Style
Put the most important information FIRST, then fill in details. NEVER write in "joke" or "novel" style where the punchline comes at the end. Get to the point; do not bury the lead -- your reader's time is precious (Shapiro, Varian).
3. One Central Contribution
Every paper must have ONE central, novel contribution. Write it down in one paragraph. If you cannot state it concisely, you have not figured it out yet. Everything in the paper serves this one contribution.
4. Concrete, Not Abstract
Say what you FIND, not what you LOOK for. Give actual coefficients, actual magnitudes, actual facts. Never write "I analyze data on X and find many interesting results." Instead: "A 10% increase in X leads to a 3% decline in Y (SE = 0.8)." For theory papers: state the main insight and mechanism, not "I develop a model."
5. Every Word Must Count
"Most paragraphs have too many sentences and most sentences have too many words." (Goldin & Katz) Cut ruthlessly. If a sentence adds nothing, delete it. Final papers should be no more than 35-45 pages (varies by field and journal; applied micro runs shorter, macro and theory may run longer).
What ships with it
4 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.
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.

econ-write is a skill published in the GitHub repository hanlulong/econ-writing-skill (592 stars, last pushed 1mo ago), licensed MIT. It adds 124 tokens to every session and 11,818 once invoked, about $0.0006 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.

review-paper
Comprehensive manuscript review with three modes: single-pass (default), --adversarial critic-fixer loop, and --peer [journal] simulated peer-review pipeline (editor + 2 dispositioned referees + editorial decision, calibrated to a target journal). R&R continuation via --peer --r2/--r3; hostile-editor stress test via…
audit-reproducibility
Enforce the replication-protocol.md rule by cross-checking numeric claims in a manuscript against the actual R / Stata / Python outputs. Report PASS/FAIL per claim against tolerance thresholds. Use before submission and before releasing a replication package.
capture-environment
Snapshot the computational environment for a replication package — detects the analysis stack (R / Stata / Python) and emits the right lockfiles (renv.lock + sessionInfo.txt, requirements.txt / environment.yml / uv.lock, Stata version + ado package list), records seeds and RNG kind, optionally writes a pinning…
data-management-plan
Draft a funder-compliant Data Management Plan (NSF DMP, NIH DMS Policy 2023, ERC, Horizon Europe) by composing the confidential-data and environment-capture primitives. Sections cover data description, formats/metadata, storage/backup, access/sharing, preservation/archiving, and roles. Use when user says "data…
grant-proposal
Scaffold a research grant proposal (NSF, NIH, ERC, or foundation) by composing existing primitives — pulls identification strategy from an /interview-me spec, delegates the data-management plan to /data-management-plan and the facilities statement to /capture-environment, and emits a funder-requirements checklist. Use…

Compute statistical power, required sample size, and minimum detectable effect (MDE) for a study design, then write a registry-ready power section. Handles two-arm RCTs (with clustering / ICC and unequal allocation), multiple-arm corrections, and a simulation-based power option for non-standard designs…
