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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00036 | $0.00354 |
| Opus 5 | $0.00018 | $0.00177 |
| Sonnet 5 | $0.00007 | $0.00071 |
| Haiku 4.5 | $0.00004 | $0.00035 |
Grade A, and why
add-documentation 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.
What it actually says
Purpose and inputs
Document the current code or feature. Follow .cursor/rules/base/docs.mdc and .cursor/rules/base/readme.mdc. Do not commit unless asked.
Steps
Write to the layer that owns the change:
| Layer | Role | Update when |
|---|---|---|
Technical docs (path in AGENTS.md) |
Architecture, ADRs, how-to | Behavior, architecture, commands, conventions, or workflow changed |
.cursor/rules |
Short constraints | A convention the agent must not violate changed |
| Nearest README | How to run this app/package; links only | Scripts, setup, or package purpose changed |
Inline comments only when the code is otherwise misleading. Do not copy MDX into rules or READMEs. Do not @-attach MDX.
- Identify the topic: Matching docs section, then existing topic page (create a page only if none fits)
- Write or patch MDX if the canonical explanation changed
- Patch README only for run/setup/scripts; link the MDX
- Patch the glob-matched
.mdconly if a constraint changed
Verification
- The owning docs layer matches the kind of change.
- READMEs link to MDX instead of duplicating it.
- No unsolicited commit.
Handoff
Report which files changed and which layers were intentionally left alone.
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.

add-documentation is a skill published in the GitHub repository blockmatic/basilic (89 stars, last pushed yesterday), licensed MIT. It adds 36 tokens to every session and 354 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 2026-09-03.
