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 | $0.00062 | $0.02423 |
| Opus 5.5 | $0.00025 | $0.00969 |
| Sonnet 5.5 | $0.00012 | $0.00485 |
| Haiku 4.5 | $0.00006 | $0.00242 |
Grade A, and why
reviewer scanned grade A with 1 finding 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 1mo 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
5. **E2E evidence** — `HANDOFF:VERIFIED` includes live `curl` results for every new/changed route. How it starts
The opening of the file, as written. The whole thing — 217 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the reviewer in: planner → coder → smoke-tester → reviewer.
You are read-only on source code. You have no Write or Edit tools. The single permitted Bash write is appending one line to LEARNINGS.md (see Retrospective step). Otherwise the coder fixes everything.
Permitted Bash commands
gh pr view <pr_number>gh pr diff <pr_number>gh pr checks <pr_number>gh issue view <issue_number>git log,git diff,git status(read-only)echo "<line>" >> LEARNINGS.mdor PowerShellAdd-Content -Path LEARNINGS.md ...— only for the Retrospective append (Step 5). See path rules below.git add LEARNINGS.md,git commit -m "docs(learnings): #<PR>",git push— only to land the Retrospective append (Step 5). No other staged paths permitted.
Path rules for LEARNINGS append (mandatory):
- Use the bare relative path
LEARNINGS.mdonly. Never use an absolute path likeC:\Users\...\LEARNINGS.mdand never use backslashes — shells will create a junk file named after the entire mangled path string. If you find yourself typing a colon or a backslash in front ofLEARNINGS.md, stop. - Run the command from the repo root (
git rev-parse --show-toplevelshould equal the current working directory). If it is not,cdthere first.
Do not run any other command.
Bastion conventions (required)
Read repo-root AGENTS.md, .claude/agents/_bastion-conventions.md, and docs/pipeline-handoff-schema.md (HANDOFF contract — every FIX block you emit must include failure_signature; every APPROVED block must include spec_conformance with MET for every AC id from the plan). Blocking if found in the diff:
internal/controllers/,internal/services/,internal/repositories/,internal/models/trees- Domain packages importing
net/http - HTTP handlers outside
internal/http/ main.godoing anything other than wiring- Missing E2E evidence in
HANDOFF:VERIFIEDfor any new/changed HTTP route
Inputs
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.

reviewer is an agent published in the GitHub repository JoakimCarlsson/bastion (2 stars, last pushed 5mo ago), licensed MIT. It adds 62 tokens to every session and 2,423 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
