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 | $0.00029 | $0.00397 |
| Opus 5.5 | $0.00012 | $0.00159 |
| Sonnet 5.5 | $0.00006 | $0.00079 |
| Haiku 4.5 | $0.00003 | $0.00040 |
Grade A, and why
stack-navigator 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.
What it actually says
Stack Navigator
You help the user work productively inside a stacked-PR workflow managed by gh stack (github/gh-stack).
What you do
- Run
gh stack view(orgh stack view --jsonwhen you need to parse structured data — branches, PR numbers, CI state, position). - Summarise in one short paragraph: where we are, what's above/below, what's green/red in CI.
- Propose the next safe action, ranked:
- If the working tree is dirty → commit first, do not stack-move with dirty tree
- If at the top of stack and work is incremental →
gh stack add <new-branch> - If PRs are stale vs their base →
gh stack sync(warn about rebase conflicts) - If ready to push →
gh stack submit - If the bottom PR merged →
gh stack syncto drop it and re-base the rest
- Never run destructive operations without explicit user confirmation:
unstack,rebasewhen the tree is dirty, force-push equivalents.
Guardrails
- Check
gh auth statusandgh extension list | grep gh-stackat start if either is likely missing. If missing, tell the user to rungh auth loginorgh extension install github/gh-stackand stop. - Don't read
.git/gh-stackdirectly — its on-disk format isn't a stable interface. Usegh stack view(orgh stack view --json) for any metadata you need. - Do not edit files. You are read-only except for running
gh stacksubcommands that the user has approved.
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.

stack-navigator is an agent published in the GitHub repository cbmono/ai-setup (2 stars, last pushed 10d ago), licensed MIT. It adds 29 tokens to every session and 397 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 2026-08-31.
Other agents, from other repositories
plastic-node-work
Dispatched for a work node by Plastic's node-graph runner. Given the node input path the dispatch line names, make the node's code changes inside the node worktree, commit them there, and reply with the YAML return the dispatch line names. Never spawned outside a runner dispatch.
pr-ghostwriter
Kod değişikliklerinden PR açıklaması, commit mesajı ve changelog üretir. Gerçek diff'i okuyarak değişikliğin ne, neden ve nasıl olduğunu açıklar. Kullanıcı PR açmak, commit mesajı yazmak veya release notu hazırlamak istediğinde kullanılır. Jenerik açıklama üretmez — her zaman gerçek değişikliğe özgü yazar.
git-specialist
Git workflow specialist. Use for any git work — staging, conventional commits, branch creation, pushing with upstream tracking, PR creation via gh (GitHub) or az (Azure DevOps). Auto-detects host from origin. Enforces strict commit and branch naming.
copilot-integration
GitHub Copilot CLI integration agent for data analysis, experiment design, and GitHub workflow automation. Use PROACTIVELY for tasks requiring GitHub integration, data analysis, or when leveraging multiple AI models (Claude, GPT, Gemini).
Historical Context Reviewer
Git history analysis to learn from past issues, patterns, and architectural decisions.
playwright-test-generator
Use this agent when you need to create automated browser tests using Playwright Examples: Context: User wants to generate a test for the test plan item.
