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 5.1 | $0.00029 | $0.00435 |
| Opus 5.5 | $0.00012 | $0.00174 |
| Sonnet 5.5 | $0.00006 | $0.00087 |
| Haiku 4.5 | $0.00003 | $0.00044 |
Grade A, and why
knowledge-base-builder 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 1mo 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
Knowledge Base Builder
Purpose
Create durable markdown knowledge bases that the assistant and user can search later. This skill favors clear structure, source links, and update workflows over one-off summaries.
When To Use
Use for project wikis, personal knowledge bases, research collections, docs indexes, FAQ sets, and reusable notes.
Inputs And Evidence
- Topic, source files/links, desired structure, audience, and update cadence.
- Existing notes and memory/search results.
Tool Map
search_workspaceread_filewrite_notememory_searchresearch_webpagesdoc-coauthoringagent_skill_script_catalogagent_skill_script_run
Native Scripts
scripts/build_markdown_index.py: builds a JSON index of markdown files with titles, relative paths, and link counts. Use it for a mechanical inventory before model-led knowledge-base organization.
Workflow
- Define the knowledge base purpose and folder/note structure.
- Collect source evidence and avoid duplicate pages.
- Write concise pages with source references.
- Add indexes, tags, and cross-links when useful.
- Record update rules or triggers if ongoing maintenance is desired.
- Verify created notes and searchability.
Native Implementation Boundaries
- Use Stram file, memory, and web tools.
- Do not import external reference llm-wiki scripts.
- Do not build hidden vector stores unless a native retrieval tool exists.
Safety And Approval
- Respect source privacy and copyright.
- Keep personal/private knowledge out of public folders.
- Do not overwrite existing notes without confirmation.
Verification
- Confirm created paths and key source links.
- Search for duplicate/related notes.
- Report what is not covered.
Failure Modes
- Creating a pile of summaries without navigation.
- Losing provenance.
- Mixing private and public knowledge.

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.

knowledge-base-builder is a skill published in the GitHub repository CodeInfinity1/Stram (11 stars, last pushed 2mo ago), licensed MIT. It adds 29 tokens to every session and 435 once invoked, about $0.0001 per session on Opus 5.5. 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.
