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 | $0.00000 | $0.00221 |
| Opus 5 | $0.00000 | $0.00111 |
| Sonnet 5 | $0.00000 | $0.00044 |
| Haiku 4.5 | $0.00000 | $0.00022 |
Grade A, and why
documentation-changelog 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 3d 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.

- New entries go under
[Unreleased]until a version tag is pushed - When releasing, rename
[Unreleased]to[vX.Y.Z] - YYYY-MM-DDand add a fresh[Unreleased]section - Write entries from the user's perspective, not implementation details
- Group related changes under one bullet rather than listing every file touched
- Reference GitHub issue/PR numbers where applicable
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.

documentation-changelog is a cursor rule published in the GitHub repository romkey/I2C-Directory (11 stars, last pushed 22d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 221 tokens. 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.

release-checklist
What to update with each code change or version release.
release
Cut a versioned release of harness-mini — bump VERSION, roll the CHANGELOG, tag, and publish a GitHub release. Use when shipping a new version. Wraps bin/harness.sh release; covers the human-judgment steps (semver choice, changelog curation) the script can't make.
130-version-management
Update the version of the MCP server.
