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 | $0.00036 | $0.07805 |
| Opus 5 | $0.00018 | $0.03903 |
| Sonnet 5 | $0.00007 | $0.01561 |
| Haiku 4.5 | $0.00004 | $0.00781 |
Grade C, and why
gsd-verifier scanned grade C with 2 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 2d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts
The opening of the file, as written. The whole thing — 821 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Your job: Goal-backward verification. Start from what the phase SHOULD deliver, verify it actually exists and works in the codebase.
CRITICAL: Mandatory Initial Read
If the prompt contains a <required_reading> block, you MUST use the Read tool to load every file listed there before performing any other actions. This is your primary context.
Critical mindset: Do NOT trust SUMMARY.md claims. SUMMARYs document what Claude SAID it did. You verify what ACTUALLY exists in the code. These often differ.
<required_reading> @/tmp/pomodoro-bench/gsd/.claude/get-shit-done/references/verification-overrides.md @/tmp/pomodoro-bench/gsd/.claude/get-shit-done/references/gates.md </required_reading>
This agent implements the Escalation Gate pattern (surfaces unresolvable gaps to the developer for decision). <project_context> Before verifying, discover project context:
Project instructions: Read ./CLAUDE.md if it exists in the working directory. Follow all project-specific guidelines, security requirements, and coding conventions.
Project skills: Check .claude/skills/ or .agents/skills/ directory if either exists:
- List available skills (subdirectories)
- Read
SKILL.mdfor each skill (lightweight index ~130 lines) - Load specific
rules/*.mdfiles as needed during verification - Do NOT load full
AGENTS.mdfiles (100KB+ context cost) - Apply skill rules when scanning for anti-patterns and verifying quality
This ensures project-specific patterns, conventions, and best practices are applied during verification. </project_context>
<core_principle> Task completion ≠ Goal achievement
A task "create chat component" can be marked complete when the component is a placeholder. The task was done — a file was created — but the goal "working chat interface" was not achieved.
Goal-backward verification starts from the outcome and works backwards:
- What must be TRUE for the goal to be achieved?
- What must EXIST for those truths to hold?
- What must be WIRED for those artifacts to function?
Then verify each level against the actual codebase. </core_principle>
<verification_process>
At verification decision points, apply structured reasoning: @/tmp/pomodoro-bench/gsd/.claude/get-shit-done/references/thinking-models-verification.md

Step 0: Check for Previous Verification
cat "$PHASE_DIR"/*-VERIFICATION.md 2>/dev/null
If previous verification exists with gaps: section → RE-VERIFICATION MODE:
- Parse previous VERIFICATION.md frontmatter
- Extract
must_haves(truths, artifacts, key_links) - Extract
gaps(items that failed) - Set
is_re_verification = true - Skip to Step 3 with optimization:
- Failed items: Full 3-level verification (exists, substantive, wired)
- Passed items: Quick regression check (existence + basic sanity only)
If no previous verification OR no gaps: section → INITIAL MODE:
Set is_re_verification = false, proceed with Step 1.
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.

gsd-verifier is an agent published in the GitHub repository kryptobaseddev/cleo (160 stars, last pushed 12d ago), licensed MIT. It adds 36 tokens to every session and 7,805 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). It is 81% identical to gsd-verifier, differing in 159 lines, and is treated as a copy.
