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 medium
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 →
- medium Excessive Agency · line 73 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00114 | $0.01346 |
| Opus 5 | $0.00057 | $0.00673 |
| Sonnet 5 | $0.00023 | $0.00269 |
| Haiku 4.5 | $0.00011 | $0.00135 |
Grade A, and why
update-rules 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 11d 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 — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Update Rules and Configuration
Update existing AGENTS.md/CLAUDE.md and .rules/ files from the latest plugin templates. Non-destructive: never overwrite user customizations, always preview changes before applying.
When to Use
- After plugin templates have been updated with new rules or improvements
- When adding a rule file introduced after initial project setup
- When checking if project rules are current with latest best practices
- When checking existing project rules against newer templates. For installing
or updating user-level instructions across Claude, Codex, Copilot, or Cursor,
use
install-user-instructionsinstead. - When a user wants to know what changed in the templates since they last synced
Two Operating Levels
Project Level (/update-rules project)
Update the current project's configuration:
-
.rules/directory sync -- Compare each template rule file against the project's.rules/directory:MISSING-- new in templates, not in project. Show purpose and offer to add.CHANGED-- exists but differs from template. Show unified diff, suggest merge.CURRENT-- matches template. Report as up to date.CUSTOM-- user-added rule not in templates. Preserve completely, report.
-
AGENTS.mdsection comparison -- Extract H2 headers from both template and project AGENTS.md. Identify missing sections. For matching sections, compare content and suggest updates. Preserve all project-specific customizations (replaced placeholders, custom guidelines, architecture maps). If the project only has CLAUDE.md, offer to migrate shared content into AGENTS.md and leave CLAUDE.md as the Claude adapter. -
What gets compared:
- Template
rules/*.mdvs.rules/*.md - Template
AGENTS.mdsections vs./AGENTS.mdsections (script emitsPROJECT_SECTION_SOURCE=agents|claudeso a CLAUDE.md fallback is never silently treated as AGENTS.md) - The CLAUDE.md adapter check is performed as an LLM read step (verify it begins with
@AGENTS.mdand contains only Claude-specific additions), not part of the script output
- Template
What ships with it
1 file 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.

update-rules is a skill published in the GitHub repository neuromechanist/research-skills (45 stars, last pushed 8d ago), licensed BSD-3-Clause. It adds 114 tokens to every session and 1,346 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.
