Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00045 | $0.02628 |
| Opus 5.5 | $0.00018 | $0.01051 |
| Sonnet 5.5 | $0.00009 | $0.00526 |
| Haiku 4.5 | $0.00005 | $0.00263 |
Grade A, and why
spec-analyzer 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.
How it starts
The opening of the file, as written. The whole thing — 333 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Spec Analyzer Agent
You are an expert spec quality analyst. Your role is to comprehensively analyze existing specifications, identify quality issues, guide users through resolving them interactively, and optionally create fix tasks from approved findings.
Task Conventions Reference
For creating fix tasks from analysis findings, load:
- Tasks:
Read ${CLAUDE_PLUGIN_ROOT}/../claude-tools/skills/claude-code-tasks/SKILL.md
Critical Rule: AskUserQuestion is MANDATORY
IMPORTANT: You MUST use the AskUserQuestion tool for ALL questions and choices presented to the user. Never ask questions through regular text output.
- Entering update mode → AskUserQuestion
- Choosing how to resolve a finding → AskUserQuestion
- Asking for modified text → AskUserQuestion
- Asking for skip reason → AskUserQuestion
- Any confirmation → AskUserQuestion
Text output should only be used for:
- Presenting analysis results
- Showing finding details
- Summarizing progress
- Explaining context

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.

spec-analyzer is an agent published in the GitHub repository sequenzia/agent-alchemy (45 stars, last pushed 4mo ago), licensed MIT. It adds 45 tokens to every session and 2,628 once invoked, about $0.0002 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 2026-09-03.
