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 | $0.00060 | $0.01734 |
| Opus 5.5 | $0.00024 | $0.00694 |
| Sonnet 5.5 | $0.00012 | $0.00347 |
| Haiku 4.5 | $0.00006 | $0.00173 |
Grade A, and why
opensource-guide-coach 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.
This is a copy
100% identical to opensource-guide-coach — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 219 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Overview
Use the official Open Source Guides as a coaching framework for open source questions.
This skill is for diagnosis and action planning, not just summarization. Infer the user's situation, route them to the most relevant guide topics, and turn the advice into a practical next-step plan. Stay advisory by default: do not draft repository policies, governance docs, or contributor materials unless the user explicitly asks for those artifacts.
Source Of Truth
- Use the official Open Source Guides site: https://opensource.guide/
- Use
references/guide-map.mdto select the right topic quickly - Use
references/persona-router.mdto infer the closest audience persona - Use
references/attribution.mdfor source links, attribution, and license notes - Copy official guide titles and canonical URLs exactly from
references/guide-map.md
Treat the guides as curated community practice, not binding policy. The guides are especially strong for maintainership, community health, contributor experience, governance, and project sustainability questions.
When To Use
Use this skill when the user is trying to:
- decide whether or how to open source a project
- attract users or contributors
- improve onboarding or contribution flow
- reduce maintainer overload or burnout
- set governance or decision-making expectations
- adopt or enforce a code of conduct
- choose useful project metrics
- think about funding or sustainability
- understand open source legal basics
- tighten project security practices
Do not use this skill for:
- GitHub product how-to questions that need product docs
- repository-specific legal advice that requires a lawyer
- deep software security implementation guidance unrelated to open source project operations
Working Style
1. Identify the situation
Infer:
- the closest persona
- the project stage: considering launch, early launch, growing, overwhelmed, or formalizing
- the main pain point
- whether the user wants advice, a checklist, or actual drafted artifacts
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.

Other skills, from other repositories
docs-governance
Route broad documentation-governance requests to existing ECC skills and run an opt-in, read-only audit of mapped documentation roles, links, ADR indexes, and evidence references. Use when a user asks for documentation governance, project-knowledge organization, documentation integrity, or a deterministic docs audit…
notion
Search, read, create, and update Notion pages via the Notion MCP.
parallel-feature-development
Coordinate parallel feature development with file ownership strategies, conflict avoidance rules, and integration patterns for multi-agent implementation. Use this skill when decomposing a large feature into independent work streams, when two or more agents need to implement different layers of the same system…
meeting-action-items
Turn meeting notes into cited decisions, owners, tickets.
create-stories
Breaks one epic into implementable stories with acceptance criteria. Use when the user wants stories for an epic or the next batch of work to build. Not for turning the whole design into epics.
story-readiness
Checks whether a story is ready to implement: clear acceptance criteria, no open questions, valid ADR and dependencies. Use when the user asks if a story, or the sprint's stories, are ready to start or build.
