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 | $0.00041 | $0.00997 |
| Opus 5.5 | $0.00016 | $0.00399 |
| Sonnet 5.5 | $0.00008 | $0.00199 |
| Haiku 4.5 | $0.00004 | $0.00100 |
Grade A, and why
codex-simplify 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 5d 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.

Simplify: Code Review and Cleanup
Review the requested scope for reuse, quality, and efficiency. Fix actionable issues using the rules in CLAUDE.md.
Phase 1: Identify Changes
For an implementation cleanup, use the ticket or feature diff, including its committed changes. For a follow-up, use the delta since the reviewed revision plus unresolved findings. Include staged and unstaged changes when present. Record the scope and revision so a clean working tree or compaction does not reopen completed work.
The three-agent pass below is the initial cleanup of that scope. After fixes, check the findings and subsequent changes directly; repeat the full pass only for substantial new scope or risk, or an explicit user request.
Phase 2: Launch Three Review Agents in Parallel
Use the Agent tool (for Codex: spawn_agent; for OpenCode: Task) to launch all three agents concurrently in a single message. Pass each agent the full diff so it has the complete context.
Agent 1: Code Reuse Review
For each change:
- Search for existing utilities and helpers that could replace newly written code. Look for similar patterns elsewhere in the codebase:
packages/*/src/core/,packages/*/src/ports/,packages/open-cloud/src/internal/,packages/testing/src/, and files adjacent to the changed ones. - Flag any new function that duplicates existing functionality. Suggest the existing function to use instead.
- Flag any inline logic that could use an existing utility: environment access outside
packages/bedrock/src/core/get-environment.tsandpackages/bedrock/src/cli/, hand-rolled Open Cloud requests that bypasspackages/open-cloud/src/internal/resource-client.ts, ad-hoc type guards, and similar patterns.
Agent 2: Code Quality Review
Review the same changes for hacky patterns:
- Redundant state: state that duplicates existing state, cached values that could be derived, observers that could be direct calls
- Parameter sprawl: adding new parameters to a function instead of generalizing or restructuring existing ones
- Copy-paste with slight variation: near-duplicate code blocks that should be unified with a shared abstraction
- Leaky abstractions: exposing internal details that should be encapsulated, or breaking existing abstraction boundaries; I/O inside
core/, adapters reached without a port, or process access (process.exit,process.argv,process.env) outsidepackages/bedrock/src/cli/ - Stringly-typed code: using raw strings where constants, string unions, or branded types already exist in the codebase; errors that bypass the classes in
packages/open-cloud/src/errors/ - Type escapes:
ascasts,nullwhere the codebase usesundefined, and: unknownannotations on values that are already typed (CLAUDE.md, "Type Conventions") - Unnecessary comments: comments explaining WHAT the code does, narrating the change, defending the choice, or referencing the task, caller, or an ADR: delete. A comment states an invariant in a line or two; the argument for an edit goes in the commit
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

codex-simplify is a skill published in the GitHub repository christopher-buss/bedrock (19 stars, last pushed today), licensed MIT. It adds 41 tokens to every session and 997 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 2026-10-20.
