Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00043 | $0.03871 |
| Opus 5 | $0.00022 | $0.01936 |
| Sonnet 5 | $0.00009 | $0.00774 |
| Haiku 4.5 | $0.00004 | $0.00387 |
Grade A, and why
dedupe-analyze 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 5d 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 — 411 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MISSION
Phase 2 of the dedupe skill: consume the blocks manifest produced by
/dedupe-setup, narrow the O(N²) pair space through a staged pipeline,
and dispatch one classifier subagent per surviving pair to produce a
verdict file.
Part of the dedupe- command family.* Run after /dedupe-setup. Run
before /dedupe-report.
Invariant Principles
- Narrowing is staged — each pair that reaches the classifier has passed every prior gate in order.
- Mechanical safety floor short-circuits classification — any pair
with a block flagged
inline_mandatory_mechanical=trueis recorded as a KEEP-flavored verdict withsource=mechanical_floorwithout a classifier dispatch. - Structural template floor short-circuits classification — any
intra-bucket pair whose heading-topic bucket key (derived per
skills/dedupe/references/segmentation-protocol.md§3) matches the allowlist inskills/dedupe/references/template-headings.mdis recorded asKEEP-placementwithsource=structural_templatewithout a classifier dispatch. Cross-bucket pairs surfaced by triage are exempt to preserve drift detection. - One subagent per surviving pair — each pair gets exactly one
Taskdispatch with a per-pair randomized 16-hex-char sentinel nonce wrapping the inert-DATA blocks. - Off-schema fails safe toward KEEP — verdict-scoped only; the coercion rule is defined in the canonical home (see References).
- Triage off-schema HALTS — a malformed triage response means the cross-bucket signal is unreliable; halting is the safety-preserving choice. There is no triage coercion.
- Off-schema halt threshold is 25% — running rate over the last 20 verdicts (or all verdicts if M < 20). Exceeding the threshold HALTS analyze with a failure report. This is NOT verdict coercion; the halt produces a failure artifact, not a misleading clean run.
Halt-not-coerce invariant: The 25% off-schema halt threshold and the triage-off-schema HALT are correctness-preserving safety stops. Producing a coerced-clean report when the cross-bucket signal or the per-pair classifier signal is degrading would mask exactly the failures the skill exists to surface. HALT is the correct response, not best-effort completion.
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.
- 5d ago First seen · 411 lines · 43 tokens per session scan A 3e4772f44e8a
dedupe-analyze is a command published in the GitHub repository axiomantic/spellbook (10 stars, last pushed yesterday), licensed MIT. It adds 43 tokens to every session and 3,871 once invoked, about $0.0002 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.
