Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

SkillSpector: 16 findings, 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 →

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 | $0.07402 |
| Opus 5.5 | $0.00014 | $0.02961 |
| Sonnet 5.5 | $0.00007 | $0.01480 |
| Haiku 4.5 | $0.00004 | $0.00740 |
Grade A, and why
nerdbot 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.
How it starts
The opening of the file, as written. The whole thing — 467 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Nerdbot
Build, query, and maintain Obsidian-native, git-friendly, agent-managed knowledge bases that separate raw evidence from synthesized wiki knowledge. Nerdbot is for layered KBs with provenance, indexes, schema/config, shared vault conventions, and append-only activity logging.
NOT for: freeform note-taking, docs site maintenance (docs-steward), database-backed knowledge systems (database-architect), or one-off research that does not maintain a repository (research).
Input: $ARGUMENTS — mode keywords, topics, repo paths, or natural-language KB requests.
Dispatch Table
$ARGUMENTS |
Workflow | First move |
|---|---|---|
| (empty) | Interview | Show mode menu; if headless, run inventory-only planning and do not mutate files |
create <topic> |
Create | Establish an Obsidian-native KB root, layered structure, shared vault surfaces, starter indexes, and activity log |
ingest <source-or-path> |
Ingest | Add sources to raw/, preserve originals, then update indexes and provenance stubs |
enrich <page-or-topic> |
Enrich | Improve wiki/ pages from raw or canonical inputs with traceable synthesis |
audit [path] |
Audit | Run inventory + lint read-only; report structure, provenance, and drift findings |
query <question-or-topic> |
Query | Answer from wiki/ + indexes/ first, inspect raw/ only to verify citations or confirm gaps, and stay read-only |
derive <artifact-or-target> |
Derive | Generate reproducible outputs from the current KB without replacing canonical material |
improve <path> |
Existing repo | Start with inventory-first, Obsidian-native overhaul planning before any expansion or refinement |
migrate <path-or-scope> |
Migration | Run the risky-change interview + inversion before any move, rename, cutover, or replacement |
| Natural language: "create a knowledge base / vault for ..." | Create | Treat the remainder as topic and scope; default to an Obsidian-native vault |
| Natural language: "ingest/import these sources" | Ingest | Route sources into raw/ and update indexes |
| Natural language: "improve/fix this knowledge base/repo/vault" | Existing repo | Start with a read-only inventory, vault classification, and additive-first repair plan |
| Natural language: "query/search/ask this KB/wiki/vault about ..." | Query | Read maintained wiki/ + indexes/, answer with provenance, and recommend enrich or ingest if the KB has a gap |
Natural language mentioning Obsidian, vault, .obsidian, [[wikilinks]], embeds, or Dataview |
Create / Existing repo / Audit | Route to the matching workflow with Obsidian-native assumptions turned on |
| Natural language: "audit/lint/check the knowledge base" | Audit | Stay read-only unless the user explicitly asks for fixes |
replay [operation-id] |
Utility | Dry-run replay against activity/operations.jsonl; do not mutate files |
watch-classify <path> |
Utility | Classify a filesystem event for watch-mode safety without mutating files |
| Requests for generic notes or docs-site work | Refuse + redirect | Redirect to the correct workflow or specialized skill |

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.
- 1mo ago First seen · 467 lines · 36 tokens per session scan A ef9a360f48a2
nerdbot is a skill published in the GitHub repository wyattowalsh/agents (5 stars, last pushed 1mo ago), licensed MIT. It adds 36 tokens to every session and 7,402 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.
