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 | $0.00890 | $0.00890 |
| Opus 5 | $0.00445 | $0.00445 |
| Sonnet 5 | $0.00178 | $0.00178 |
| Haiku 4.5 | $0.00089 | $0.00089 |
Grade A, and why
.agents AGENTS.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 today.
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 — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
.agents
.agents/ is the canonical source. templates/ may contain only host-specific differences; do not duplicate canonical content there.
Commands
- Before finishing any change:
make check(runs every CI gate from ci.yml locally) - After changing
scripts/install.shor installer behavior:bats test/ - Before finishing a shell-script change:
shfmt -d scripts - Before finishing an installer change:
shellcheck scripts/install.sh
Run asdf install shfmt or asdf install bats when a tool is unavailable.
Gotchas
- The installer skips a host whose root directory does not exist; inspect its output.
--rulesdoes not remove stale destination files. Legacy Working Agreement cleanup happens only after a successful--contextinstallation.- A Claude
pathsoverlay marks a rule that must not become an OpenCode global instruction. --contextoverwrites the host-native context file and removes only legacy rules that match the canonical content.lint,typecheckand the other file-selecting gates readgit ls-files; an untracked file is skipped silently and the gate can still exit 0. Stage it first.- Everything tracked under
.agents/skills/ships to five host directories; keep tests and fixtures intest/, which ships nowhere.
Boundaries
These constraints protect canonical source files and installed host views.
Always
- Keep behavior shared by hosts in
.agents/; add host-specific frontmatter or prompt fragments only intemplates/. - Run
make validateafter changing a skill. - Follow the surrounding style. Do not refactor adjacent legacy content without a separate task.
Ask first
- Changes to host-wide settings in
.claude/,.gemini/, or.opencode/. - Installer destinations or stale-file migration behavior.
- Canonical skill content, its validators, or vendor templates.
Never
- Edit installed files under
$HOMEas a substitute for updating this source repository. - Copy a path-scoped Claude rule into OpenCode's global rules.
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.
