OPC Skills is a collection of reusable instruction folders, scripts, and resources that extend coding agents with specialized tasks for solopreneurs and one-person companies. Its skills cover areas such as search optimization, demand research, domain discovery, branding, social-media assets, and platform-specific research. The catalogue entries are the project's own skills, plugins, and hook.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00065 | $0.00498 |
| Opus 5 | $0.00032 | $0.00249 |
| Sonnet 5 | $0.00013 | $0.00100 |
| Haiku 4.5 | $0.00006 | $0.00050 |
Grade A, and why
archive 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.

What it actually says
Archive Skill
Capture, index, and reuse project knowledge across sessions.
When to Archive
- After completing a significant task (deploy, migration, major feature)
- After resolving a tricky debugging session
- When the user says "archive this"
- After any multi-step process with learnings worth preserving
When to Consult Archives
- Before debugging infrastructure, deploy, or CI issues
- Before repeating a process done in a past session
- When encountering an error that may have been solved before
Search: grep -ri "keyword" .archive/
Index: .archive/MEMORY.md
Archive Workflow
- Read
.archive/MEMORY.md— check for related existing archives - Create
.archive/YYYY-MM-DD/directory if needed - Write markdown file with YAML frontmatter (see
references/TEMPLATE.md) - Update
.archive/MEMORY.md: add one-line entry under the right category - If related archives exist, add
relatedfield in frontmatter
Lookup Workflow
- Read
.archive/MEMORY.mdto find relevant entries - Read the specific archive file for detailed context
- Apply learnings to current task
Categories
- infrastructure — AWS, ECS, IAM, networking, secrets, CloudWatch
- release — TestFlight, versioning, Git Flow, CHANGELOG
- debugging — Bug fixes, error resolution, gotchas
- feature — Feature design, implementation notes
- design — UI/UX, icons, visual design
Rules
.archive/must be in.gitignore— local-only notes- Keep entries concise but reproducible
- Focus on problems, fixes, and exact commands
- Always update MEMORY.md after creating an archive
- Use descriptive filenames (e.g.,
cloudwatch-logging.mdnotsession.md) - Include YAML frontmatter with
tags,category, and optionalrelated
What ships with it
4 files 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.

archive is a skill published in the GitHub repository ReScienceLab/opc-skills (1,757 stars, last pushed today), licensed Apache-2.0. It adds 65 tokens to every session and 498 once invoked, about $0.0003 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 2026-08-30.
Other skills, from other repositories
context-okf-llm-ingest
Use when extracting a codebase's implementation decisions into Metatron with an LLM/agent instead of metatron ingest — authoring candidate decisions as Open Knowledge Format (OKF) markdown files locally for review.
create-opc-wiki
Scaffold a personal LLM wiki (Karpathy pattern) — multi-agent, MCP-ready, with SEO/GEO publish target. Compiles knowledge into a persistent wiki instead of re-deriving from raw docs on every query. One paste from any agent (OpenClaw, Claude Code, Codex, Cursor, Hermes) installs it.
research-wiki
Persistent research knowledge base that accumulates papers, ideas, experiments, claims, and their relationships across the entire research lifecycle. Inspired by Karpathy's LLM Wiki pattern. Use when user says "知识库", "research wiki", "add paper", "wiki query", "查知识库", or wants to build/query a persistent field map.
wiki-status
Show the current state of the wiki — what's been ingested, what's pending, and the delta between sources and wiki content. Use this skill when the user asks "what's the status", "how much is ingested", "what's left to process", "show me the delta", "what changed since last ingest", "wiki dashboard", or wants an…
wiki-import
Import a wiki knowledge graph into the current vault — either from a graph.json export file (stubs) or from an OKF (Open Knowledge Format) markdown bundle (full page bodies). Use this skill when the user says "import wiki", "import from export", "load graph.json", "import vault", "import OKF bundle", "import OKF"…
hermes-history-ingest
Ingest Hermes agent history into the Obsidian wiki. Use this skill when the user wants to mine their past Hermes sessions for knowledge, import their /.hermes folder, extract insights from previous Hermes conversations, or says things like "process my Hermes history", "add my Hermes memories to the wiki", "ingest…
