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

tcx-fundamental 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 6d 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

Fundamental Analysis

Use this skill for business, accounting, financial statement, issuer, protocol/project, sector, and fundamental quality analysis when the installed workflow can support the requested universe.

Universe method:

  • Public equity: analyze business model, financial statement linkage, earnings quality, cash conversion, DuPont-style driver decomposition when useful, management, capital allocation, operating KPIs, source/as-of posture, and evidence gaps.
  • ETF/index: analyze constituent, sector, factor, liquidity, passive-flow, and methodology fundamentals only when supported by evidence.
  • Crypto public markets: analyze protocol economics, supply, usage, governance, liquidity, and ecosystem fundamentals as research context only.
  • Macro/rates/FX/commodities: identify the relevant fundamental transmission channel and call out specialist underwriting gaps rather than inventing unsupported coverage.
  • Credit signals may inform common-equity or portfolio downside; do not underwrite debt securities unless a dedicated credit workflow is installed.

Expected output:

  • Universe and workflow type
  • Business model
  • Revenue and margin drivers
  • Balance sheet and cash flow quality
  • Earnings-quality, cash-conversion, statement-linkage, and red-flag notes
  • Management and capital allocation
  • Fundamental risks
  • Evidence and source notes
  • Source/as-of posture, stale data, and missing support gaps

Decision quality fields when applicable:

  • evidence_grade, source_freshness, source_quality
  • scenario_cases, contrary_evidence, update_triggers
  • invalidation_conditions, decision_readiness, confidence
  • forecast permission fields when prediction or decision support is in scope

Role-specific quality:

  • State what matters most for the company instead of listing generic ratios.
  • Explain drivers, risks, and uncertainty in plain causal terms.
  • Reconcile filing-derived aggregates to the underlying filing or disclosure: identifier/accession, accepted or published time, form, fiscal period, units, and amendment posture. For a historical cutoff, use only the version available then; a latest company-facts view cannot silently replace it.
  • Distinguish issuer/company fundamentals from security actionability; good fundamentals alone are not a buy decision.
  • Use ready-for-portfolio-risk when conclusion-driving fundamentals have current, attributable support and material conflicts and gaps are explicit. Use factual-baseline, screen-grade, or not-decision-ready only when a material missing input prevents the stronger conclusion; credible provider-normalized or secondary evidence does not trigger an automatic downgrade.
  • Do not fabricate financial metrics, source facts, filings, or validation results.
  • Keep unresolved questions and needed evidence in the report body or missing_evidence. When a distinct follow-up proposal is material, encode it as a structured follow_up_requests object required by the artifact tool; never submit a string list.

Changes

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.
