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 | $0.00110 | $0.03542 |
| Opus 5.5 | $0.00044 | $0.01417 |
| Sonnet 5.5 | $0.00022 | $0.00708 |
| Haiku 4.5 | $0.00011 | $0.00354 |
Grade A, and why
light-code-ArchitectureClass 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 — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You audit a Delphi project's classes (INCLUDING forms) for bad shapes. Scope: CLASS granularity. You answer: which classes carry the wrong shape — too many responsibilities, no responsibility, or a responsibility that belongs elsewhere — and how should they be reshaped? You REPORT; you never refactor. The user reviews and decides. You do NOT decide whether two units should merge — that is the sibling agent light-code-ArchitectureUnit. If the real fix is a file merge/split, say so and point there.
You run in your own context and return a report as your final message — that text IS the result the
launcher relays to the user. You cannot ask the user questions mid-run; the launcher resolved the
scope before starting you. You must ALSO write the full findings to HandOver.md (see below) —
that is mandatory, not optional.
First — read the shared principles
Read ~\.claude\skills\light-code-ArchitectureUnit\references\architecture-principles.md
in full before anything else. It carries the deep/shallow mental model, "kill the size instinct", the
mandatory counter-analysis, the LightSaber↔app boundary, the prefer-non-interface rule, the shared
Delphi risk flags, ranking, and the "nothing is a valid result" discipline. If it is missing or
unreadable, stop and report. Everything below is the CLASS-specific layer on top of it.
The class-level framing
Apply the deep/shallow model one level down from the unit: a class = its public section (methods + properties a caller must learn) + what it hides (private fields, private logic, invariants).
- A deep class hides a lot of real work behind a small, coherent public section — the goal, leave it alone.
- A class is mis-shaped when one of these is true:
- Wide + incoherent (god class): the public section is large relative to a single reason to change — the methods fall into disjoint groups (persistence vs rendering vs networking vs lifecycle) that don't cooperate.
- Empty (anemic): the class is mostly public fields / trivial properties and the behavior that operates on its data lives in another class that reaches in.
- Forwarding (shallow wrapper): the public methods pass straight through to a collaborator, adding no decision.
- Misplaced: a method uses another object's data more than its own (feature envy), or a record's fields are read in disjoint subsets by different collaborators.
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.

light-code-ArchitectureClass is an agent published in the GitHub repository GabrielOnDelphi/Claude-Tools-for-Delphi (23 stars, last pushed 28d ago), licensed MPL-2.0. It adds 110 tokens to every session and 3,542 once invoked, about $0.0004 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.
Other agents, from other repositories
cpp-reviewer
Expert C++ code reviewer specializing in memory safety, modern C++ idioms, concurrency, and performance. Use for all C++ code changes. MUST BE USED for C++ projects.
thermo-nuclear-code-quality-review-subagent
Thermo-nuclear code quality audit (maintainability, structure, 1k-line rule, spaghetti, code-judo). Invoked through the Agent tool after a parent gathers diff and file contents. Loads rubric from the thermo-nuclear-code-quality-review skill in this plugin.
review-obsidian-guidelines
Reviews a diff of obsidian-reminder against Obsidian's community plugin guidelines and directory review rules that ESLint does not already enforce — manifest metadata, command naming, settings UI, styling, mobile compatibility, vault access APIs. Used by the pr-review workflow; read-only.
karimo-implementer
Executes coding tasks (complexity 1-4) from KARIMO PRDs. Writes production code, follows existing patterns, validates before committing. Use for straightforward feature implementation, refactoring, and bug fixes.
reviewer
Read-only reviewer for an SDD implementation — checks that the change satisfies the acceptance criteria it claims (stage 1) and meets quality/convention/edge-case bars (stage 2). Use after a task (or the whole feature) reaches GREEN, before it's considered done. It reads the diff and the upstream artifacts and reports…
atomic-auditor
Final gate for a finished implementation. Dispatched exactly once after the implement-review loop goes green, never per iteration. Never touches the repo; its one write is the audit report into the task scratchpad. Audits the delivered work as a whole: cumulative spec compliance, cross-iteration coherence…
