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 | $0.00458 | $0.00458 |
| Opus 5.5 | $0.00183 | $0.00183 |
| Sonnet 5.5 | $0.00092 | $0.00092 |
| Haiku 4.5 | $0.00046 | $0.00046 |
Grade A, and why
ack-dev-skills AGENTS.md 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.
How it starts
The opening of the file, as written. The whole thing — 28 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ACK Development Workspace
This is a multi-repo workspace for AWS Controllers for Kubernetes (ACK).
Development guidance lives in ./ack-dev-skills/. Install the plugin or read the skill files for full context.
Skills
| Skill | When to Use | Entry Point |
|---|---|---|
ack-dev |
General ACK development — setting up environments, adding resources/fields, code generation, hooks, references, testing, PRs. Use when working in any ACK controller repo or code-generator. | skills/ack-dev/SKILL.md |
resolve-issue |
End-to-end issue workflow — fetches an ACK community issue, triages it, classifies it, then drives it to resolution (bug fix, new resource, new field, feature investigation). Invoke with an issue number. | skills/resolve-issue/SKILL.md |
References
Shared reference documentation available to all skills:
| Reference | Purpose |
|---|---|
| generator.yaml Reference | Complete documentation of all generator.yaml options — top-level config, resource-level (synced, updateable, deletable, tags, print, compare), operations, field-level (classification, immutability, comparison, references, late-init), renames, exceptions, and hooks. Sourced from code-generator/pkg/config/. |
| Bug Fix Patterns | 10 common root causes found in closed ACK bugs — infinite reconcile, nil panics, orphaned resources, missing filters, broken tags, etc. Match symptoms to fix approaches. |
| New Resource Checklist | Feasibility checks (standalone CRD vs field-on-parent), API investigation steps, configuration decision table, and post-generation review checklist. |
Setup
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.
