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.

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 | $0.00000 | $0.00259 |
| Opus 5 | $0.00000 | $0.00130 |
| Sonnet 5 | $0.00000 | $0.00052 |
| Haiku 4.5 | $0.00000 | $0.00026 |
Grade A, and why
update-docs scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
/stacks:update-docs
Refresh the compressed documentation index by fetching the latest from docs.stacks.co/llms.txt.
When to Use
- When the plugin suggests documentation may be outdated
- When you notice missing documentation paths
- Periodically to ensure the index is current
Instructions
Step 1: Run the Update Script
Run the update script to fetch and compress the latest docs index:
node "${CLAUDE_PLUGIN_ROOT}/scripts/update-docs-index.js" "${CLAUDE_PROJECT_ROOT}/.claude/stacks/knowledge/general-stacks-knowledge.md"
If the project knowledge file doesn't exist yet, update the plugin source instead:
node "${CLAUDE_PLUGIN_ROOT}/scripts/update-docs-index.js"
Step 2: Confirm Update
Tell the user the results shown by the script (path count and size).
Notes
- The script fetches from https://docs.stacks.co/llms.txt
- Non-English docs (zh, es) are filtered out
- Press/brand sections are excluded (not useful for development)
- The index is compressed into Vercel's format:
dir:{file1.md,file2.md,...}|dir2:{...}
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-docs is a command published in the GitHub repository kenny-stacks/stacks-claude-plugin (11 stars, last pushed 7mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 259 tokens. 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.
