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.

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 | $0.00050 | $0.00107 |
| Opus 5 | $0.00025 | $0.00053 |
| Sonnet 5 | $0.00010 | $0.00021 |
| Haiku 4.5 | $0.00005 | $0.00011 |
Grade A, and why
implement 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 yesterday.
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
Capstone: implement
From this skill's base directory, read ../core/references/core.md
and ../core/references/core-authoring.md, then execute
../core/references/protocols/implement.md
exactly.
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.

implement is a skill published in the GitHub repository GentBajko/capstone (2 stars, last pushed 3d ago), licensed Apache-2.0. It adds 50 tokens to every session and 107 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 2026-08-31.
Other skills, from other repositories
write-changelog
Generates a CHANGELOG.md entry for a release by summarizing git commits since the last tag. Groups changes by type: Added, Changed, Fixed, Removed. Follows Keep a Changelog format (https://keepachangelog.com). Invoked when the user asks to update the changelog, write release notes, or prepare a release.
write-readme
Generates or updates a README.md for a project or package. Reads the source code to understand the project and produces a clear, accurate README following the project's conventions. Invoked when the user asks to write, update, or generate a README.
project-map
Generates a compact structural orientation document (.agentic/project-map.md) so any agent can understand codebase structure without filesystem exploration. Invoked when onboarding to a codebase, exploring unfamiliar projects, or auditing code layout and conventions.
format-markdown
Formats Markdown files consistently using project-native tooling first (repo scripts/config), then safe fallback formatters, and verifies the result with lint/check commands. Invoked when the user asks to format markdown, tidy docs, normalize README files, or fix markdown style drift.
write-adr
Creates an Architecture Decision Record (ADR) documenting a significant technical decision. Follows the standard ADR format with context, decision, and consequences. Invoked when the user says "write an ADR", "document this decision", or "create an architecture record".
sync-confluence
Syncs engineering documentation (ADR, RFC, architecture) from docs/engineering/ to Confluence Cloud using the mark tool. Operates in two modes: scaffold (creates the directory tree locally) and CI sync (pushes on every main push). Only files with mark metadata headers are synced. Enforces diagram hierarchy (Mermaid >…
