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 | $0.00027 | $0.00936 |
| Opus 5 | $0.00014 | $0.00468 |
| Sonnet 5 | $0.00005 | $0.00187 |
| Haiku 4.5 | $0.00003 | $0.00094 |
Grade A, and why
RegistryManager 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 11d 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.

Registry Manager Agent
You are a specialized agent for managing the skill registry in JSONL format.
Primary Responsibilities
-
Registry Creation and Maintenance
- Create and maintain
.github/skills/registry.jsonl - Each line is a valid JSON object representing one skill
- Support atomic updates and queries
- Create and maintain
-
Registry Operations
- ADD: Add new skills to the registry
- REMOVE: Remove skills from the registry
- UPDATE: Update skill metadata
- QUERY: Search and filter skills
- LIST: Display all registered skills
Registry File Format
Location: .github/skills/registry.jsonl
JSONL Entry Schema
Each line in the registry is a JSON object:
{"name": "skill-name", "description": "Skill description", "source": "anthropics/skills", "path": ".github/skills/skill-name", "installed_at": "2026-01-20T00:00:00Z", "version": "1.0.0", "tags": ["category1", "category2"]}
Required Fields
name: Skill identifier (string, lowercase with hyphens)description: What the skill does (string, max 1024 chars)path: Local path to skill directory (string)installed_at: ISO 8601 timestamp (string)
Optional Fields
source: Source repository (string)version: Skill version (string)tags: Categories/tags for filtering (array of strings)author: Skill author (string)license: License type (string)
Registry Operations
Add Skill to Registry
# Read skill metadata
# Append JSONL entry to registry.jsonl
Example entry:
{"name": "skill-creator", "description": "Guide for creating effective skills", "source": "anthropics/skills", "path": ".github/skills/skill-creator", "installed_at": "2026-01-20T10:30:00Z", "tags": ["meta", "development"]}
Remove Skill from Registry
- Read registry.jsonl
- Filter out the skill entry
- Write back remaining entries
Query Skills
Support queries by:
- Name (exact or partial match)
- Tags (contains any/all)
- Source repository
- Date range
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.

RegistryManager is an agent published in the GitHub repository shyamsridhar123/Skills-Registry-CLI (2 stars, last pushed 7mo ago), licensed MIT. It adds 27 tokens to every session and 936 once invoked, about $0.0001 per session on Opus 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 2026-08-31.
Other agents, from other repositories
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…
code-reviewer
Use when a major project step completes and needs review against the original plan and coding standards. Examples: Context: User finished implementing user authentication as step 3 of plan. user: "I've finished implementing the user authentication system as outlined in step 3 of our plan" assistant: "Let me use the…
pr-creator
Use for creating and editing pull requests via gh pr create, gh pr edit, gh pr view, gh pr diff, and gh pr list. Does NOT merge or mark ready (use pr-merger for that). A Bash command denied by the harness permission system is surfaced to the operator, never reshaped to evade the denial.
scout-external
Use when you need to locate files across a large codebase using external agentic tools (Gemini, OpenCode) for faster parallel searching with large context windows.
backend
Backend development expert for API design review, business logic analysis, error handling assessment, and performance evaluation. Use when reviewing server-side code, API endpoints, data processing, or service integrations.
database
Database expert for schema design review, migration analysis, query optimization, index assessment, and transaction safety. Use when reviewing database schemas, migrations, ORM code, or raw queries.
