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 5.1 | $0.00000 | $0.00483 |
| Opus 5.5 | $0.00000 | $0.00193 |
| Sonnet 5.5 | $0.00000 | $0.00097 |
| Haiku 4.5 | $0.00000 | $0.00048 |
Grade C, and why
example-skill scanned grade C with 1 finding 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.
Hidden instructionshighPrompt injection
Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.
<!-- SKILL.md is the main instruction file for a skill. It's loaded into context when the user invokes this skill. Think of skills as specialized "modes" for Claude Code — each skill gives Claude domain expertise, workfl How it starts
The opening of the file, as written. The whole thing — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Example Skill
Before You Start
Read required context:
references/guidelines.md # Domain-specific guidelines
Read learned patterns:
LEARNED.md # What worked (and didn't) in previous sessions
Workflow
- Read the required context files listed above
- Understand the user's request
- Follow the rules below
- Verify output against the checklist
Rules
- Always verify facts before including them in output
- Use project terminology consistently (see references/)
- Ask the user when requirements are ambiguous — don't guess
- Keep output focused and actionable
Self-Learning
Read LEARNED.md before starting. Update it when you discover:
- Patterns that work well for this skill
- Common mistakes or gotchas
- User preferences learned during use
Consolidation (target ~50 lines): Before adding a new entry, check file length. If approaching 50 lines:
- Merge duplicate/overlapping entries
- Remove entries that haven't been reinforced
- Keep only entries that would change behavior
What ships with it
2 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.

example-skill is a skill published in the GitHub repository lukasz-fedor/claude-memory-template (31 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 483 tokens. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

done
End the current Awareness memory session and save final progress.
save
Save current session progress to Awareness memory as a batch of structured steps.
session-start
Initialize memory session, load project context, and create a sessionid for tracking.
recall
Search Awareness memory for past implementations, decisions, or relevant context.
setup
Setup Awareness Memory — check local daemon, authenticate via browser, and configure credentials.
