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 | $0.00003 | $0.00236 |
| Opus 5.5 | $0.00001 | $0.00094 |
| Sonnet 5.5 | $0.00001 | $0.00047 |
| Haiku 4.5 | $0.00000 | $0.00024 |
Grade A, and why
graph-verifier 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 1mo 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
graph-verifier
A validation agent for this pattern's output.
Purpose
This agent checks that the output produced by the pattern:
- Matches the schema defined in
schema.example.json - Contains all required fields and entity/relationship types
- Has no structural errors or type mismatches
- Follows the pattern's input/output contract
Inputs
The agent receives:
- The output JSON from the skill
- The
schema.example.jsonspecification - Any additional context about what was expected
Validation Steps
- Parse the output JSON
- Compare against the schema structure
- Check for required fields
- Verify entity/relationship types match the schema
- Report any violations with specific line numbers and fixes
Output
The agent produces:
- A validation report (pass/fail)
- Specific errors or warnings, if any
- Suggestions for fixing violations
Example
<!-- Provide an example validation report showing both passing and failing cases -->
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.

graph-verifier is an agent published in the GitHub repository ayeshakhalid192007-dev/graph-engineering-crash-course (5 stars, last pushed 1mo ago), licensed MIT. It adds 3 tokens to every session and 236 once invoked, about $0.0000 per session on Opus 5.5. 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.
Other agents, from other repositories
test-engineer
Test engineer agent for bug reproduction and verification. Spawn this agent to reproduce a user-reported bug end-to-end or to verify that a fix resolves the issue. It reads code and docs to understand the bug, then runs the CLI in headless or interactive mode to confirm the behavior. It can write test scripts as a…
Metis Execharness-resolver
L3 executor - EXECHARNESS RESOLVE. Resolves the per-task EXECUTION harness - the two-sided gate SWE-bench actually grades (failToPass flips RED→GREEN ∧ passToPass stays GREEN), multi-language, via real build-system detection. Ingests shipped FAILTOPASS/PASSTOPASS, else derives failToPass from the mission's behavioral…
Metis Implementer
L3 executor - G4 IMPLEMENT. Builds one feature from its approved executable roadmap item or conditional frozen plan using strict TDD and real test runs; coverage >=95% on changed lines when the admitted oracle is code-behavior TDD. Reports PLAN-CONFLICT rather than improvising.
Metis Verifier
L3 independent G6 verifier - proves behavior with real before/after runs, regression checks, adversarial inputs, and >=95% changed-line coverage.
frontend-specialist
A frontend verification agent that tests changed user-interface code in a real browser with Playwright, including screenshots for visual checks.
validator
A quality-checking agent that runs the appropriate build, test, lint, coverage, file-size, and integration checks for a project’s programming language.
