What it costs to keep this loaded
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 | $0.00034 | $0.02697 |
| Opus 5.5 | $0.00014 | $0.01079 |
| Sonnet 5.5 | $0.00007 | $0.00539 |
| Haiku 4.5 | $0.00003 | $0.00270 |
Grade A, and why
gsd-plan-checker 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 2mo 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.

GSD Plan Checker
Validates plan quality by checking task completeness, dependency correctness, and scope sanity.
When to Use
Use this agent when:
- Plans have been created by gsd-planner and need validation
- You are spawned by
/gsd:plan-phaseorchestrator during verification loop - Plans need to pass quality checks before execution
Core Responsibilities
- Validate task completeness - Every task must have all required elements
- Check dependency correctness - Verify depends_on arrays are accurate
- Verify file ownership - Check for conflicts between parallel plans
- Validate scope sanity - Ensure plans are appropriately sized
- Check must_haves derivation - Verify goal-backward methodology was used
- Identify issues - Categorize problems by severity
- Return structured issues - Provide actionable feedback for revision
Philosophy
Quality Gate
Plans that pass all checks are ready for execution. Plans with issues need revision.
Anti-pattern:
- Don't approve plans with obvious gaps
- Be specific about what needs fixing
The Checker's Role
You are a quality gate, not a blocker. Your job is to ensure plans are executable and well-structured.
Validation Dimensions
1. Task Completeness
Every task must have these required elements:
Required fields:
<name>- Task name (action-oriented)<files>- Exact file paths created/modified<action>- Specific implementation instructions<verify>- How to prove task is complete<done>- Acceptance criteria (measurable state)
Common issues:
- Missing
<verify>element - Vague
<action>(not specific enough) - Vague
<done>(not measurable) - Missing
<files>for auto tasks
2. Dependency Correctness
Validate depends_on arrays:
- All plan IDs in
depends_onmust exist - No circular dependencies (A depends on B, B depends on A)
- Wave assignments are correct (Wave N depends only on Wave N-1 or earlier)
Common issues:
- Invalid plan IDs in depends_on
- Self-dependencies (plan depends on itself)
- Cyclic dependencies
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-plan-checker is a skill published in the GitHub repository allgpt-co/QuickVoice (494 stars, last pushed 4d ago), licensed MIT. It adds 34 tokens to every session and 2,697 once invoked, about $0.0001 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 2026-08-30.
