### Other Agent Skills hosts (OpenClaw, NemoClaw, Pi, Hermes, …)
Agent hosts differ in install paths, discovery settings, and support for optional frontmatter fields. `npx skills add` (Option 1) commonly installs into the `~/.agents/skills/` convention, with project-scoped installs under`.agents/skills/`; confirm both paths against your host's current documentation. To install manually on a host configured to scan one of those locations:
You usually don't need anything host-specific. `npx skills add` (Option 1) installs into the shared `~/.agents/skills/` convention, and any compliant client that scans that directory — including **OpenClaw**, **NVIDIA NemoClaw** (an OpenClaw-based secure runtime), and **Pi** — discovers the skills automatically. Project-scoped installs land in`.agents/skills/` and work the same way. To install without the CLI, clone straight into either location:
For Hermes versions that support skill taps, add the repository as a tap:
**Hermes** is the one host that uses its own registry instead of the shared directory, so add the repo as a tap:
```bash
hermes skills tap add K-Dense-AI/scientific-agent-skills
```
Every `SKILL.md` has YAML frontmatter, but legacy and community skills vary in `metadata` formatting (block or flow style) and optional extension fields. Repository updates must keep `metadata.version` as a quoted numeric string and pass canonical `skills-ref validate ./skills/<skill-name>` checks. Hosts may interpret optional metadata and credential prompts differently, so verify behavior on the target host. Because 150 skills add up to a lot of standing context, consider installing a topical subset rather than the whole collection.
These skills stay portable across all of them: `metadata` is single-line JSON (so OpenClaw's line-based reader parses it), credentialed skills declare a top-level `required_environment_variables` field (so Hermes prompts for keys), and unknown fields are ignored everywhere else. Because 147 skills add up to a lot of standing context, consider installing a topical subset rather than the whole collection.
> **NemoClaw note:** NemoClaw runs agents inside NVIDIA OpenShell with default-deny outbound networking. Skills are discovered and loaded normally, but any skill that needs the network — package installs via `uv`, or API calls (Exa, Parallel, Benchling, NCBI, Materials Project, …) — only works once the operator pre-approves the relevant domains in the OpenShell TUI.

## Reporting a vulnerability
**Please do not open a public issue for a security vulnerability.**
Use GitHub's private vulnerability reporting, which keeps the report confidential until a fix is available:
> **Security** tab → **Report a vulnerability**
<!-- TODO(maintainers): add a monitored security contact address here as a second channel,
or delete this comment if private vulnerability reporting is the only intended route. -->
Please include, as far as you are able:
- The affected skill (or repository tooling) and the version or commit you observed it on
- What an attacker could achieve, and what access they would need to achieve it
- The steps to reproduce, ideally with the smallest input that triggers it
- Any agent host and model you reproduced it on, since skill behavior varies by host
We will acknowledge your report and tell you whether we consider it in scope. If we accept it, we will keep you informed as we work on a fix and will credit you in the release notes unless you ask us not to.

## What is in scope
This repository distributes **Agent Skills**: instructions, reference material, and bundled scripts that an AI agent reads and may execute on your machine. In-scope reports concern content in this repository that could harm someone who installs it:
- A bundled script that reads credentials, files, or environment variables it has no reason to read, or that transmits data to an unexpected destination
- Instructions in a `SKILL.md` that steer an agent toward destructive, exfiltrating, or unauthorized action
- Prompt-injection vectors — including content in `references/` or `assets/` that an agent is instructed to treat as authoritative
- A skill whose documented behavior materially misrepresents what its bundled code does
- Unsafe credential handling, such as instructions to place secrets where they will be committed or logged
- Vulnerabilities in this repository's own tooling (`scan_skills.py`, `scan_pr_skills.py`, `validate_report.py`) or its GitHub Actions workflows
## What is out of scope
- **Vulnerabilities in the third-party libraries and services a skill documents.** A flaw in RDKit, Scanpy, or a public API belongs to that project — please report it upstream. A skill that *instructs users to use a library unsafely* is in scope here.
- **Vulnerabilities in agent hosts.** Issues in Claude Code, Cursor, Codex, and similar belong to those vendors.
- **The inherent capability of skills.** Skills are instructions for an agent that can execute code; a skill performing the work it documents is not a vulnerability. See the [Security Disclaimer](README.md#%EF%B8%8F-security-disclaimer) in the README.
- **Missing version pins on documented dependencies**, unless you can show a concrete exploitation path.

## Before you install
Skills execute code and influence your agent's behavior. Review what you install, and prefer installing the subset of skills you actually need. Bundled scripts that reach the network or read credentials are documented as such in the relevant `SKILL.md`. Treat skill content from any source — including this repository — as code review material, not as trusted input.
---
## Automated skill scanning
Skills in this repository are scanned using [`cisco-ai-skill-scanner`](https://pypi.org/project/cisco-ai-skill-scanner/), which combines static behavioral analysis, trigger analysis, and LLM-assisted review. Changed skills are scanned on every pull request.
The scheduled scan runs weekly and is incremental: a skill whose package contents are unchanged since the last scan carries its previous findings forward rather than being rescanned. Every skill is rescanned in full whenever the scanner version or the model changes, when a maintainer triggers a full run, and at least every 30 days regardless. Each skill's `last_scanned` date is recorded in the JSON report, so you can always see when a given finding was actually produced.
**How to read the report.** It is generated by automated tooling, including a language model, and is published to be useful rather than authoritative. It is not an audit, a certification, or a guarantee. A finding in the report is a prompt to review a skill, not a determination that the skill is malicious.
Before any report is published, `validate_report.py` checks it against the actual contents of `skills/` and blocks publication if the scan makes claims that cannot be true of the packages on disk — findings anchored to files that do not exist, cross-file behavior in single-file packages, or asserted script counts that the package does not have. When that check fails, the workflow fails and no report is published. This exists because a scanner that malfunctions would otherwise publish its own errors unreviewed.
**If you believe a finding is wrong**, open a regular issue (false positives are not sensitive) with the skill name, the rule ID, and why the finding cannot hold. If a class of false positive originates in the scanner rather than in our configuration, we will also raise it upstream.

## Reporting a malicious skill elsewhere
If you find a skill published *outside* this repository that impersonates Scientific Agent Skills or K-Dense, please tell us through the private reporting channel above so we can respond and warn users.
Scientific Agent Skills is built on the shoulders of giants. The 148 skills in this repository leverage dozens of incredible open source projects created and maintained by dedicated developers and research communities around the world.
Scientific Agent Skills is built on the shoulders of giants. The 146 skills in this repository leverage dozens of incredible open source projects created and maintained by dedicated developers and research communities around the world.
**If you find value in these skills, please consider supporting the underlying open source projects that make them possible.**
**Status:** awaiting regeneration — no validated report is currently published.
This file is the output of the automated skill scan described in the [Security Policy](../SECURITY.md#automated-skill-scanning). It is regenerated by `scan_skills.py` and published by [`.github/workflows/security-scan.yml`](../.github/workflows/security-scan.yml) only after `validate_report.py` confirms the scan's claims are consistent with the contents of `skills/`.
## Why there is no report here yet
The previous report was withdrawn rather than relocated. Verification against the repository showed it contained findings that cannot be true of the packages they describe. For example:
| Skill | The report claimed | Actually in the package |
|---|---|---|
| `seaborn` | 13 files including 3 Python scripts forming an "exfiltration chain across 3 files" | 4 files, **no** executable files |
| `umap-learn` | 23 files including 6 Python scripts, withheld to evade detection | 2 files, **no** executable files |
| `venue-templates` | Environment-variable exfiltration in `scripts/generate_schematic_ai.py` and `scripts/generate_schematic.py` | Neither file exists here; both belong to a **different** skill (`scientific-schematics`) |
These are defects in the scan pipeline, not findings about the skills. Because the report was published automatically each week with no check on its plausibility, the errors were republished unreviewed — and because the report occupied the `SECURITY.md` filename, GitHub presented it as this project's official security policy.
Two changes address that:
1. The security policy is now hand-authored at [`SECURITY.md`](../SECURITY.md), and the scan report lives here instead.
2.`validate_report.py` now runs between the scan and the commit. It fails the workflow when a report anchors a finding to a file that is not present, describes cross-file behavior in a package too small to have any, or asserts a script count the package does not have. A failing scan no longer publishes anything.
The withdrawn report remains in version control for reference:
```bash
git show a177179:SECURITY.md
```
## What replaces it
The next scheduled run regenerates this file. If it passes validation, this page is replaced by the report; if it fails, the workflow fails, this page stays as it is, and the failure output names each claim that could not be reconciled with the repository.
Investigating the underlying pipeline defect — determining whether the confabulated inventories originate in per-skill scanner state, in the prompt assembly, or in the model's response — is tracked separately. The `venue-templates` case, where findings cite another skill's files by name, points toward contamination between skills within a single scan run rather than a per-skill parsing error.

- **[Arbor](../skills/arbor/)** - Autonomous Optimization (AO) via Hypothesis Tree Refinement (HTR), adapted from the Arbor framework (Jin et al., 2026; RUC-NLPIR/Arbor). Iteratively improves a real artifact — a codebase, model-training recipe, agent/search harness, data-synthesis pipeline, or prompt — against a measurable objective over many experiment cycles, without overfitting to the feedback signal. The agent acts as a long-lived **coordinator** that maintains a persistent **hypothesis tree** (each node binds a falsifiable hypothesis, a distilled reusable insight, and a pointer to the artifact version that realizes it) and runs the six-step loop Observe → Ideate → Select → Dispatch → Backpropagate → Decide; short-lived **executor** subagents each test one hypothesis in an isolated git worktree and return a dev score, factual result, distilled insight, and branch reference. A **held-out merge gate** promotes a candidate to the best artifact only when its improvement transfers to a test evaluator the search never optimized against, separating exploratory dev gains from verified progress. Insights are propagated up the tree so local findings become direction-level constraints and global priors, and falsified branches are pruned with their reasons recorded as negative constraints. Ships a `tree.py` state manager (init/observe/add-node/set-evidence/propagate/prune/merge/status/validate) that keeps the tree consistent and auditable, plus reference docs on the HTR methodology, the executor brief, the final-report template, and how to run the upstream `arbor` CLI instead. Use cases: "improve my model's eval score in fewer steps", optimizing an agent or search harness for higher pass rate/accuracy, tuning a data-generation pipeline judged by downstream model behavior, MLE-bench / Kaggle-style "improve the submission" tasks, and any long-horizon "make this artifact better and don't just memorize the dev set" workflow that needs structured, branching exploration with an audit trail

- **[Hypothesis Generation](../skills/hypothesis-generation/)** - Version 2.0 formulates evidence-bounded questions, candidate hypotheses, rival explanations, causal or associational claims, discriminating predictions, measurements, and preregistration-ready plans. All bundled Python 3.11+ standard-library tools are local, deterministic, bounded, non-scoring, and make no network/model/image calls. Hypotheses remain proposals rather than facts; the skill never automatically ranks/selects them, infers causation, supplies clinical advice, bypasses oversight, or fabricates novelty/evidence
- **[HypoGeniC](../skills/hypogenic/)** - Plan and audit ChicagoHAI `hypogenic==0.3.5`/HypoRefine workflows over labeled text datasets, task configs, hypothesis banks, and HypoBench data. The software proposes candidate textual patterns and task-prediction statistics; held-out accuracy is not experimental confirmation, causal evidence, novelty, or scientific validity.

- **[Scientific Critical Thinking](../skills/scientific-critical-thinking/)** - Tools and approaches for rigorous scientific reasoning and evaluation
- **[Scientific Visualization](../skills/scientific-visualization/)** - Create and audit truthful, accessible, publication-ready figures with Matplotlib, Seaborn, or Plotly, including multi-panel layouts, uncertainty/missing-data displays, color/contrast review, metadata validation, and export planning. Pinned examples use Python 3.11+; bundled CLIs are network-free, while Plotly/Kaleido v1 static export needs compatible Chrome/Chromium. Preserve raw data and transformations, never hide or invent evidence, verify current journal rules, and do not claim that a palette, DPI, format, or automated report establishes accessibility or compliance
- **[Scientific Writing](../skills/scientific-writing/)** - Version 2.0 drafts, revises, and audits manuscripts or research reports with explicit evidence provenance, reporting-guideline coverage, authorship accountability, confidentiality controls, and local consistency checks. Every factual/numeric claim maps to human-verified source IDs; AI is not an author and fluency is not evidence. Bundled Python 3.11+ tools are offline, deterministic, and non-submitting; accountable human authors retain scientific decisions and final approval

The budget translates the research plan into a credible resource plan. Reviewers and program staff use it to judge whether the scope, staffing, timeline, and requested funds are aligned.
The methods section persuades reviewers that the proposed work can answer the research question with rigor, feasibility, and appropriate controls.
## Essential Components
- Study design or experimental design.
- Data sources, samples, subjects, systems, or models.
- Inclusion, exclusion, randomization, blinding, and control conditions where relevant.
- Measurements, instruments, assays, algorithms, or protocols.
- Statistical or computational analysis plan.
- Power, sample size, uncertainty, and sensitivity analysis where appropriate.
- Rigor, reproducibility, validation, and quality control.
- Alternative approaches for the most likely failure modes.
## Experimental Research
Describe biological or physical systems, controls, replicates, reagents, equipment, outcome measures, and analysis methods. Make clear which data support each hypothesis or aim.
## Computational Research
Describe datasets, preprocessing, model design, baselines, validation splits, metrics, error analysis, compute resources, software availability, and reproducibility plan.
## Clinical or Translational Research
Describe population, recruitment, consent, intervention or exposure, endpoints, monitoring, safety, regulatory approvals, and statistical analysis.
## Reviewer Checks
- Does each aim have a concrete method?
- Are controls and comparisons sufficient?
- Are sample sizes justified?
- Are assumptions explicit?
- Are risks and alternatives credible?
- Can another expert reproduce the work from the description?
A resubmission should show that the team understood reviewer concerns, made substantive improvements, and preserved the proposal's central value.
## First Step
Read the reviews in three passes:
1. Identify fatal concerns versus fixable presentation issues.
2. Group comments by theme: significance, innovation, approach, team, environment, budget.
3. Decide whether to revise, redirect to another mechanism, or build more preliminary data first.
## NIH A1 Resubmissions
- Use the introduction page to summarize major changes.
- Address all major critiques respectfully and specifically.
- Make changes visible through rewritten sections, not track changes.
- Strengthen preliminary data, rigor, statistics, or alternatives where requested.
- Do not argue with reviewers unless correcting a factual misunderstanding.
## NSF Resubmissions
NSF has no universal formal introduction page. Incorporate reviewer feedback into the revised narrative, especially around intellectual merit, broader impacts, feasibility, and clarity.
## Strong Response Patterns
- "We clarified..." for communication problems.
- "We added preliminary data..." for feasibility concerns.
- "We revised Aim 2..." for design concerns.
- "We added an alternative strategy..." for risk concerns.
- "We recruited collaborator X..." for expertise gaps.
## When Not to Resubmit Immediately
- Reviewers rejected the premise rather than the execution.
- The mechanism or program fit was poor.
- Essential preliminary data are missing.
- The team lacks required expertise.
- The budget or timeline is not credible without scope reduction.
NSF proposals are reviewed on **Intellectual Merit** and **Broader Impacts**. Strong proposals make both criteria explicit in the project summary, project description, and evaluation plan.
- Intellectual Merit: importance, originality, technical rigor, qualifications, and resources.
Most NIH research project grants receive an overall impact score informed by five scored criteria.
- Significance: importance of the problem and likely impact.
- Investigator(s): expertise, productivity, and team suitability.
- Innovation: conceptual, technical, or methodological novelty.
- Approach: rigor, feasibility, alternatives, statistics, and risk handling.
- Environment: institutional support, facilities, and collaborative setting.
Reviewers also assess protections for human subjects, vertebrate animals, biohazards, authentication, data management, and rigor and reproducibility.
## DOE
DOE review criteria vary by office and FOA, but commonly emphasize scientific and technical merit, relevance to program mission, applicant qualifications, adequacy of resources, and reasonableness of budget.
Competitive DOE proposals connect the scientific question to the office mission, national laboratory or user facility context when relevant, and measurable outcomes.
## DARPA
DARPA reviews focus on whether the work attacks a DARPA-hard problem with high payoff, credible technical milestones, and a path to transition.
- Technical innovation and risk.
- Potential impact if successful.
- Measurable milestones and demonstration plan.
- Team capability and execution speed.
- Transition relevance to defense or national-security users.
## Cross-Agency Reviewer Questions
- What important problem does this solve?
- Why is now the right time?
- Why is this team the right team?
- What makes the approach credible?
- What can go wrong, and what is the fallback?
- What will be true at the end of the award that is not true today?
The team section should convince reviewers that the proposed work has the right expertise, leadership, collaboration structure, and institutional support.
## Team Design Questions
- What expertise is essential for each aim?
- Which roles must be senior investigators versus staff or trainees?
- Where are the methodological, clinical, computational, or translational gaps?
- What facilities, cores, field sites, datasets, or partnerships are required?
- Who owns coordination, data management, compliance, and dissemination?
## Roles to Define
- Principal investigator or project lead.
- Co-investigators and senior/key personnel.
- Collaborators and consultants.
- Project manager or coordinator.
- Data, software, statistics, or evaluation leads.
- Trainees and mentoring structure.
- External advisory board, if appropriate.
## Evidence of Fit
- Prior publications or preliminary data in the area.
- Complementary expertise across aims.
- Prior collaboration or a clear collaboration plan.
- Letters that commit specific resources or activities.
- Institutional support, facilities, and protected time.
## Common Pitfalls
- Adding famous names without defined roles.
- Missing key expertise for a high-risk method.
- Overloading the PI with all tasks.
- Providing generic letters of support.
- Failing to explain how multi-site coordination will work.
A timeline shows that the project is executable within the award period. It should connect aims, milestones, personnel, dependencies, deliverables, and decision points.
## Timeline Elements
- **Aims and tasks**: Break each aim into concrete work packages.
- **Milestones**: Define measurable completion points, not just activities.
- **Dependencies**: Identify tasks that require prior data, approvals, hires, or equipment.
- **Decision points**: Specify go/no-go thresholds and alternatives.
- **Deliverables**: Publications, datasets, software, prototypes, reports, or demonstrations.

### Converting .doc to .docx
## Creating with docx-js — gotchas
`docx` is preinstalled — do not run `npm install` first; write the script and `require('docx')` directly. Only if that require fails: `npm install docx`. The model knows the API; these are the footguns:
- **Page size defaults to A4.** For US Letter set `page: { size: { width: 12240, height: 15840 } }` (DXA; 1440 = 1″).
- **Tables need dual widths:** set `columnWidths` on the table AND `width` on every cell, both in `WidthType.DXA` (PERCENTAGE breaks in Google Docs). Column widths must sum to the table width.
- **Table shading:** use `ShadingType.CLEAR`, never `SOLID` (renders black).
- **Lists:** never insert `•` literally; use a `numbering` config with `LevelFormat.BULLET`.
- **Never use `\n`** — use separate `Paragraph` elements.
- **TOC:** headings must use built-in `HeadingLevel.*`; custom heading styles need `outlineLevel` set or they won't appear.
- **Don't use a table as a horizontal rule** — use a paragraph bottom border instead.
- **Dot-leader / right-aligned-on-same-line:** use `PositionalTab` (`alignment: PositionalTabAlignment.RIGHT`, `leader: PositionalTabLeader.DOT`) inside a `TextRun`, not literal `.` or space padding.
## Verify the output
After writing a `.docx`, render it and look at it:
Legacy `.doc` files must be converted before editing:
```bash
python scripts/office/soffice.py --headless --convert-to pdf output.docx
Word splits text across many `<w:r>` runs (revision ids, spell-check markers), so a phrase you can see in the document often doesn't exist as a contiguous string in the XML. `merge_runs.py` merges adjacent identically-formatted runs in `word/document.xml` without changing content or rendering; it also accepts a `.docx` directly (`python scripts/merge_runs.py doc.docx -o merged.docx`).
**Tracked changes:** when redlining, validate with `--author "<the name you redlined under>"` (needs `--original`) — it reports any text you changed without a `<w:ins>`/`<w:del>` around it, which is easy to do by accident and invisible in the accepted view. Wrap runs in `<w:ins>`/`<w:del>` with `w:id`, `w:author`, `w:date` attributes. Inside `<w:del>`, the text element is `<w:delText>`, not `<w:t>`. A deleted paragraph mark (`<w:pPr><w:rPr><w:del w:id=".." w:author=".." w:date=".."/></w:rPr></w:pPr>`) means "merge this paragraph into the next" — so deleting a paragraph outright is that plus a `<w:del>` around every run. The `<w:del/>` must come before the rPr's other children; their order is schema-enforced.
To produce a clean copy with all tracked changes accepted: `python scripts/accept_changes.py in.docx out.docx`.
Accepting a deleted paragraph mark should join that paragraph to the one below it, so a paragraph whose runs are *all* deleted vanishes. Word does this; `accept_changes.py` and `pandoc --track-changes=accept` don't always. Both fail the same way — they strip the deleted text but leave the emptied paragraph behind, which reads as a stray empty bullet when it was auto-numbered:
- `pandoc --track-changes=accept` never joins the paragraphs.
- `accept_changes.py` (LibreOffice) joins them correctly, except when the deleted paragraph is followed by an empty spacer paragraph.
An empty bullet in either view is an artifact of that view, not a defect in the document. Check paragraph deletions in the XML.
## Comments
Comments require six cross-linked files. Use the helper — directory mode when you'll also be editing `document.xml` (saves an unzip/rezip cycle), `.docx`-direct mode otherwise:
### Converting to Images
```bash
# Against an already-unpacked directory (preferred when also placing markers)
python scripts/comment.py unpacked/ "Fees & expenses cap is too low"
python scripts/comment.py contract.docx "This cap is too low" -o annotated.docx
python scripts/office/soffice.py --headless --convert-to pdf document.docx
pdftoppm -jpeg -r 150 document.pdf page
```
The script writes `comments.xml`, `commentsExtended.xml`, `commentsIds.xml`, `commentsExtensible.xml`, the relationships, and the content-type overrides. Comment IDs are auto-assigned. It then prints the `<w:commentRangeStart>`/`<w:commentRangeEnd>`/`<w:commentReference>` snippet to add to `word/document.xml` so the comment anchors to specific text — until you place those markers, the comment exists but is not visible.
### Accepting Tracked Changes
## Dependencies
To produce a clean document with all tracked changes accepted (requires LibreOffice):
`docx` (npm, preinstalled — install only if `require('docx')` fails) · `pandoc` · LibreOffice (`soffice`) · `pdftoppm` (Poppler)

## Creating New Documents
Generate .docx files with JavaScript, then validate. Install: `npm install -g docx`
new Paragraph({ numbering: { reference: "bullets", level: 0 },
children: [new TextRun("Bullet item")] }),
new Paragraph({ numbering: { reference: "numbers", level: 0 },
children: [new TextRun("Numbered item")] }),
]
}]
});
// ⚠️ Each reference creates INDEPENDENT numbering
// Same reference = continues (1,2,3 then 4,5,6)
// Different reference = restarts (1,2,3 then 1,2,3)
```
### Tables
**CRITICAL: Tables need dual widths** - set both `columnWidths` on the table AND `width` on each cell. Without both, tables render incorrectly on some platforms.
```javascript
// CRITICAL: Always set table width for consistent rendering
// CRITICAL: Use ShadingType.CLEAR (not SOLID) to prevent black backgrounds
children: [new TextRun("Page "), new TextRun({ children: [PageNumber.CURRENT] })]
})] })
},
children: [/* content */]
}]
```
### Critical Rules for docx-js
- **Set page size explicitly** - docx-js defaults to A4; use US Letter (12240 x 15840 DXA) for US documents
- **Landscape: pass portrait dimensions** - docx-js swaps width/height internally; pass short edge as `width`, long edge as `height`, and set `orientation: PageOrientation.LANDSCAPE`
- **Never use `\n`** - use separate Paragraph elements
- **Never use unicode bullets** - use `LevelFormat.BULLET` with numbering config
- **PageBreak must be in Paragraph** - standalone creates invalid XML
- **Use `ShadingType.CLEAR`** - never SOLID for table shading
- **Never use tables as dividers/rules** - cells have minimum height and render as empty boxes (including in headers/footers); use `border: { bottom: { style: BorderStyle.SINGLE, size: 6, color: "2E75B6", space: 1 } }` on a Paragraph instead. For two-column footers, use tab stops (see Tab Stops section), not tables
- **TOC requires HeadingLevel only** - no custom styles on heading paragraphs
- **Override built-in styles** - use exact IDs: "Heading1", "Heading2", etc.
- **Include `outlineLevel`** - required for TOC (0 for H1, 1 for H2, etc.)
Extracts XML, pretty-prints, merges adjacent runs, and converts smart quotes to XML entities (`“` etc.) so they survive editing. Use `--merge-runs false` to skip run merging.
### Step 2: Edit XML
Edit files in `unpacked/word/`. See XML Reference below for patterns.
**Use "Claude" as the author** for tracked changes and comments, unless the user explicitly requests use of a different name.
**Use the Edit tool directly for string replacement. Do not write Python scripts.** Scripts introduce unnecessary complexity. The Edit tool shows exactly what is being replaced.
**CRITICAL: Use smart quotes for new content.** When adding text with apostrophes or quotes, use XML entities to produce smart quotes:
```xml
<!-- Use these entities for professional typography -->
<w:t>Here’s a quote: “Hello”</w:t>
```
| Entity | Character |
|--------|-----------|
| `‘` | ‘ (left single) |
| `’` | ’ (right single / apostrophe) |
| `“` | “ (left double) |
| `”` | ” (right double) |
**Adding comments:** Use `comment.py` to handle boilerplate across multiple XML files (text must be pre-escaped XML):
```bash
python scripts/comment.py unpacked/ 0 "Comment text with & and ’"
**Inside `<w:del>`**: Use `<w:delText>` instead of `<w:t>`, and `<w:delInstrText>` instead of `<w:instrText>`.
**Minimal edits** - only mark what changes:
```xml
<!-- Change "30 days" to "60 days" -->
<w:r><w:t>The term is </w:t></w:r>
<w:del w:id="1" w:author="Claude" w:date="...">
<w:r><w:delText>30</w:delText></w:r>
</w:del>
<w:ins w:id="2" w:author="Claude" w:date="...">
<w:r><w:t>60</w:t></w:r>
</w:ins>
<w:r><w:t> days.</w:t></w:r>
```
**Deleting entire paragraphs/list items** - when removing ALL content from a paragraph, also mark the paragraph mark as deleted so it merges with the next paragraph. Add `<w:del/>` inside `<w:pPr><w:rPr>`:
```xml
<w:p>
<w:pPr>
<w:numPr>...</w:numPr> <!-- list numbering if present -->
