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 | $0.00592 | $0.00592 |
| Opus 5.5 | $0.00237 | $0.00237 |
| Sonnet 5.5 | $0.00118 | $0.00118 |
| Haiku 4.5 | $0.00059 | $0.00059 |
Grade A, and why
agent-skill CLAUDE.md 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.

Honeycomb Agent Skill — Development Guide
Repository Structure
This repo contains a single Claude Code plugin at honeycomb/. The root also has a marketplace manifest at .claude-plugin/marketplace.json and test infrastructure under tests/.
honeycomb/ # Plugin root
.claude-plugin/plugin.json # Plugin manifest
skills/ # 8 skill directories, each with SKILL.md + references/
agents/ # Agent definitions (.md)
commands/ # Slash commands (.md)
hooks/ # hooks.json + scripts/ for query validation
Key Conventions
- All versions (plugin.json, marketplace.json, skill metadata) must stay in sync
- Skill frontmatter must include
name,description, andmetadata.version - All intra-plugin paths use
${CLAUDE_PLUGIN_ROOT}, never hardcoded paths - Skills use
allowed-tools(hyphenated), notallowed_tools - Hook scripts must fail open (
exit 0) on errors
Tests
python -m venv .venv && source .venv/bin/activate
make install # installs test deps including skills-ref
make test # runs structural tests only
Structural tests verify:
- Plugin manifest, marketplace manifest, and directory layout
- YAML frontmatter presence and required fields in all components
- Version consistency across plugin.json and marketplace.json
- The validate-query.sh hook behavior (subprocess-based unit tests)
The tests/scenarios/ and tests/skill-pressure/ suites require a Honeycomb API key and are not part of the default make test target.
Adding a New Skill
- Create
honeycomb/skills/<skill-name>/SKILL.mdwith frontmatter:--- name: skill-name description: > What this skill does. Trigger phrases: "phrase1", "phrase2", ... metadata: version: "1.0.0" --- - Add reference files in
honeycomb/skills/<skill-name>/references/ - Add the skill name to
REQUIRED_SKILLSintests/constants.py - Run
make testto verify structure
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.

agent-skill CLAUDE.md is an instructions file published in the GitHub repository honeycombio/agent-skill (28 stars, last pushed 10d ago), licensed MIT.
