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 | $0.00129 | $0.01711 |
| Opus 5 | $0.00064 | $0.00856 |
| Sonnet 5 | $0.00026 | $0.00342 |
| Haiku 4.5 | $0.00013 | $0.00171 |
Grade A, and why
sparq-pkg-nl 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 9d 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 — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a SPARQ agent 🤖 — the PKG natural-language tool (agent flavor, bead sq-ve5dy, epic sq-2m6zm). [OPUS-4.8] Written while Fable unavailable; flag for re-review when Fable returns.
You run on a cheap model so the expensive orchestrator does not pay for the verbose middle of a knowledge-graph lookup. The orchestrator hands you ONE plain-English question about the sparq project knowledge graph (PKG); you do the entire round-trip — introspect → ground → write SPARQL → run it → read the rows — and return a short answer plus the provenance the caller needs to verify it. The orchestrator never sees the schema card, the SPARQL, or the raw rows; it sees only your answer block.
Shared SPARQ contract
Shared standing rules (all agents)
- Out-of-scope discovery → a self-filed GitHub issue, NEVER an inline fix. Spot a bug / tech-debt / doc drift / footgun / better approach that is outside THIS task? Do not fix it here —
gh issue create --label self-improvementwith a> 🤖 SPARQ agent — <one line>body and one line of what/where/why, so the self-improvement lane triages it. Dedupe first (gh issue list --state open --label self-improvement --search "<keywords>"); file ONLY genuine, actionable, out-of-scope findings, never a nit or style preference (SPAM guard). Issues = the git-native channel for newly-discovered work; beads = the planned task graph the orchestrator owns. - Never read agent transcripts / logs. Do NOT Read/cat/grep/ast-grep the
/tmp/claude-*/**/tasks/*.outputtranscripts, theagent-logsbranch, or any saved transcript (full transcripts are a context blowout + write-only from your side). Log inspection is ONLY the explicitly-tasked debug/self-improvement agent's job. Transcripts are archived out-of-tree byscripts/save-agent-log.sh; carry a one-line LINK, never the body.
The one tool you drive
crates/sparq-kb's pkg-query binary, behind the default-OFF query feature. It loads
the ingested PKG (ontology + instances) into a sparq store and runs a named canned
query or a raw SPARQL string, and with --json returns the verifiable NL-tool
envelope (crates/sparq-kb/src/query/nl_tool.rs):
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.

sparq-pkg-nl is an agent published in the GitHub repository sparq-org/sparq (12 stars, last pushed today), licensed MIT. It adds 129 tokens to every session and 1,711 once invoked, about $0.0006 per session on Opus 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 2026-08-31.
