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 | $0.00138 | $0.04146 |
| Opus 5 | $0.00069 | $0.02073 |
| Sonnet 5 | $0.00028 | $0.00829 |
| Haiku 4.5 | $0.00014 | $0.00415 |
Grade A, and why
selftune 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 283 lines — stays where its author put it; the contents beside it link to each section on GitHub.
selftune
Observe real agent sessions, detect missed triggers, grade execution quality, evolve skills through package evaluation (replay, baseline, grading, body, unit tests, and post-deploy watch), and scaffold workflow skills from repeated telemetry patterns.
You are the operator. The user installed this skill so YOU can manage their skill health autonomously. They will say things like "set up selftune", "improve my skills", or "how are my skills doing?" — and you route to the correct workflow below. The user does not run CLI commands directly; you do.
Bootstrap
If ~/.selftune/config.json does not exist, read workflows/Initialize.md
first. The CLI must be installed (selftune on PATH) before other commands
will work. Do not proceed with other commands until initialization is complete.
Primary Lifecycle
Default to this lifecycle unless the user explicitly asks for a low-level workflow:
-
status- use
selftune status - for draft packages, use
selftune create status --skill-path <path>
- use
-
verify- use
selftune verify --skill-path <path> - if verify reports missing readiness or evidence, follow the returned next low-level command instead of rerunning the full chain
- use
-
publish- for draft packages, use
selftune publish --skill-path <path> - for already-live skills,
publishusually means a validatedImproveaction plusWatch
- for draft packages, use
-
improve- use
selftune improve --skill <name> --skill-path <path> - let
--scope autochoose bounded package search automatically when the skill already has package evidence or a draft package manifest - set
--scope description|routing|body|packagewhen the measured gap is already clear and you want to force the mutation surface - use
--scope packagewhen the problem spans routing and body together or you want measured frontier comparison before deciding what to publish - omit
--dry-runwhen you want the winning package candidate promoted back into the draft automatically
- use
What ships with it
60 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.
- 2d ago First seen · 283 lines · 138 tokens per session scan A 38704bd2e1a8
selftune is a skill published in the GitHub repository selftune-dev/selftune (16 stars, last pushed 2d ago), licensed MIT. It adds 138 tokens to every session and 4,146 once invoked, about $0.0007 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 2026-08-30.
