Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
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 | $0.00105 | $0.01799 |
| Opus 5.5 | $0.00042 | $0.00720 |
| Sonnet 5.5 | $0.00021 | $0.00360 |
| Haiku 4.5 | $0.00011 | $0.00180 |
Grade A, and why
ring:planning-codebase-simplification 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 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.
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 — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Dev Simplify — Whole-Codebase Structural Sweep
When to use
- User asks to simplify, flatten, or audit architecture of a whole codebase
- User mentions "too much indirection", "kill shims", "unnecessary abstractions"
- Pre-public application where break-compatibility refactor is cheap
- Post-pivot cleanup: speculative scaffolding accumulated during exploration
Skip when
- Diff review on a feature branch → use ring:reviewing-code
- Standards-conformance refactor → use ring:planning-backend-refactor
- Dead code from a specific change → use ring:dead-code-reviewer in ring:reviewing-code
- Application already has external clients depending on internals

Complementary: ring:reviewing-code, ring:codebase-explorer Similar: ring:planning-backend-refactor, ring:auditing-production-readiness
Core principle: DELETE is the default verdict. An abstraction survives only with concrete evidence of the swap it enables.
Hard Constraint
Default: public APIs MUST NOT break (HTTP routes, SDK surface, webhooks, event contracts).
Supply hard_constraint input to override. Must be declared — never auto-inferred.
Dispatch Protocol
⛔ STOP-CHECK BEFORE DISPATCH
Before emitting any Task call, count the explorers you intend to launch in this turn.
- Count MUST equal 6 (or 5 if branch has no commits ahead of main — Task 5 skipped).
- If your dispatch count diverges → STOP and reconcile against the task table below.
- No substitutions, no omissions.
⛔ MUST NOT trickle-dispatch
All explorers leave in the SAME TURN, before reading any explorer output.
Forbidden sequences:
- Dispatch explorer 1 → read result → dispatch explorer 2
- Dispatch a subset → wait → dispatch the rest
- Dispatch follow-up explorers conditioned on partial output
- Loop sequentially over the task list
If you find yourself about to dispatch an explorer in a turn AFTER any explorer has already returned a result → STOP. You violated parallel dispatch. Report the violation and mark the phase INCOMPLETE rather than completing the trickle.
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.

ring:planning-codebase-simplification is a skill published in the GitHub repository LerianStudio/ring (218 stars, last pushed 6d ago), licensed Apache-2.0. It adds 105 tokens to every session and 1,799 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 2026-09-03.

antidote
Stop AI agents from patching symptoms. Use this skill when coding, reviewing, refactoring, auditing, committing fixes, or adding guards, validation, workarounds, or 20+ lines without deleting code.
review
Structured code review with parallel audit agents, confidence-scored triage, and optional auto-fix. Examines uncommitted changes, staged diffs, commit ranges, or specific paths. Produces a tiered report (MUST-FIX / RECOMMENDED / NIT) backed by evidence, then optionally applies fixes with verification.
write-tests
Write tests for existing production code. Processes ONE file at a time through a full pipeline: analyze, inventory (frozen BEFORE writing), write, executable coverage gate, verify, blind coverage audit, adversarial review, log. Uses CodeSift for discovery and analysis when available. Modes: [path] (specific target)…
db-audit
Database performance and safety audit. 70+ checks across 13 dimensions (DB1-DB13): query patterns, indexes, schema design, connections, transactions, migrations, caching, query optimization, ORM anti-patterns, observability, data lifecycle, DB security, and migration deployment safety. Code-level checks for all ORMs.…
brainstorm
Explores a codebase, researches the problem space, and produces an approved design specification before any code is written. Use when the user wants to create a new feature, add significant functionality, redesign a subsystem, or build something that touches multiple parts of the project.
