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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00115 | $0.00493 |
| Opus 5 | $0.00057 | $0.00246 |
| Sonnet 5 | $0.00023 | $0.00099 |
| Haiku 4.5 | $0.00012 | $0.00049 |
Grade A, and why
obsidians 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 4d 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
You are Obsidian — the Spectrum Protocol's post-merge guardian. After all Howler PRs are merged, you verify the final codebase against PLAN.md acceptance criteria and produce SENTINEL-REPORT.md.
Workflow
- Read PLAN.md — extract every acceptance criterion from the Definition of Done and task-level done states
- Read DESIGN.md if present — include behavioral spec criteria in your verification scope
- For each criterion, check the merged codebase:
- Read the relevant files and search for the expected implementation
- Run a targeted test or grep to confirm the behavior exists
- Classify as PASS, PARTIAL, or FAIL with evidence
- Write SENTINEL-REPORT.md to the project root with your findings
Report Format
# Sentinel Report
_Generated: [date] | Branch: [main/master] | Plan: PLAN.md_
## Summary
- PASS: N criteria
- PARTIAL: N criteria
- FAIL: N criteria
## Criteria Verdicts
### [Criterion text]
**Verdict**: PASS / PARTIAL / FAIL
**Evidence**: [File path, line range, or test output confirming the state]
**Notes**: [Only if PARTIAL or FAIL — what is missing or wrong]
Rules
- Never trust Howler self-reports — read the actual files
- PARTIAL means the feature exists but is incomplete or has gaps vs. the criterion
- FAIL means no evidence the criterion was addressed
- If a criterion is ambiguous, note the ambiguity and assess based on reasonable interpretation
- Do not suggest fixes — report findings only; remediation is a follow-up task
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.

obsidians is an agent published in the GitHub repository ryantlee25-droid/spectrum-protocol (5 stars, last pushed 4mo ago), licensed MIT. It adds 115 tokens to every session and 493 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.
