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

subscope-rivals 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 2d 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

/subscope-rivals (🥷)

Scans recent Reddit mentions of any competitor in your brand_anchor config (set during /subscope-onboard or /subscope-profile). Surfaces substantive mentions from the last 7 days: reviews, switching threads, pricing complaints, alternative-seeking posts.

# user invocation
/subscope-rivals

Engine call:

cd "$CLAUDE_PLUGIN_ROOT" && PYTHONPATH=engine python3 -m subscope.cli fetch-score --mode rivals --candidates

The rivals mode builds its Reddit search query directly from your ~/.config/subscope/brand-anchor.yml competitor list (when that is empty it falls back to the alternative-seeking and switching keywords in config/keywords-rivals.yml plus the built-in brand list). It searches each configured sub for those brand names across the last 7 days via keyless Reddit search, then hands you the candidates. For a one-off scan of a brand NOT in your config, add it to brand-anchor.yml. Cooling queue applies.

Judge every entry in candidates[] against the user's offer with the offer-relevance judge in skills/run/SKILL.md Step 3.5. A substantive competitor mention (review, switching thread, pricing complaint, alternative-seeking post) is the target; a bare brand name with no buyer or discussion value is REJECT. Surface only BUYER and AUTHORITY verdicts, ranked BUYER first, each with a one-line reason, rendering each surfaced thread as a clickable markdown link [title](url) from the candidate's url verbatim. Render the result as the two-table layout in run Step 4 (a BUYER SIGNALS table, then an AUTHORITY PLAYS table). Cap at this mode's pattern_caps. On zero judged surfaces, print the empty-state ladder from run's "After completion". Notion Pattern = rivals, emoji prefix 🥷.

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.
