Token cost

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.

Security

Grade A, and why

updating-knowledge 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.

The opening of the file, as written. The whole thing — 152 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Updating Knowledge

Core Principles

  • Systematic > ad-hoc - Follow research methodology, don't scatter searches randomly
  • Cross-validate - Verify claims across multiple independent sources
  • Confidence tracking - Explicitly flag single-source claims and gaps
  • Concise output - Present findings efficiently, introspection in thinking blocks

Preflight Check

This skill requires web_search tool access.

Verify it's available before proceeding. If it isn't, tell the user immediately — "I need web search enabled for research tasks. Please toggle on 'Web search' in the feature menu." — and stop there rather than researching from memory alone or spending context on workarounds.

Trigger Disambiguation

Avoid triggering on generic action verbs like "update" (which could mean file/code changes instead) — trigger on the explicit knowledge-gathering requests named in the description above.

Research Workflow

1. Scope Definition (internal)

Identify in thinking block:

  • What specifically needs investigation
  • Current knowledge baseline
  • Known gaps
  • Required depth (overview vs comprehensive)

2. Source Gathering (2-10 tool calls)

Source priority:

  1. Official documentation, project repos, company announcements
  2. Academic papers, technical blogs with clear expertise
  3. Community discussions (for ecosystem context only)

Tool selection:

  • web_search - Find authoritative sources
  • web_fetch - Extract complete content from any URL (no prior search required)
  • Internal tools (GitHub, Drive, etc.) - Company/personal context
  • Multiple tool types as needed

Gather 3-5 diverse sources minimum for cross-validation.

3. Synthesis (internal)

In thinking block:

  • Cross-validate major claims across sources
  • Note contradictions explicitly
  • Track publication dates
  • Assess source credibility
  • Identify remaining gaps

4. Output (concise)

Present findings concisely:

## [Topic]

**Key findings:**
[2-3 sentence summary with most important updates]

**Current state:**
[Concise description of what's true now]

**Changes since cutoff:**
[Only if relevant - what's different]

**Gaps:**
[Only if user needs to know - what wasn't found]

Sources: [URLs]

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.
