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 | $0.03826 | $0.03826 |
| Opus 5.5 | $0.01530 | $0.01530 |
| Sonnet 5.5 | $0.00765 | $0.00765 |
| Haiku 4.5 | $0.00383 | $0.00383 |
Grade A, and why
skills 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 yesterday.
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 — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent instructions
This repository is the source of the Open Mercato Skills collection: seventy-four agent skills (skills/<name>/SKILL.md) that run a full PR pipeline or stop at a staged human-review handoff — plan, implement, review, QA gate, merge — installable into any repo via skills.sh. The deliverables here are markdown skill documents plus a small amount of shell/Node tooling; there is no application code.
Task routing
| When the task involves… | Read first | Key rules |
|---|---|---|
Editing or adding a skill (skills/<name>/SKILL.md) |
DECISIONS.md, scripts/lint.sh, the Cross-skill contract section below, the skill's own references/ dir if present |
Frontmatter name must equal the directory name and description must be present (≤500 chars — lint-enforced; aim for ≤350). Content must stay product-agnostic: no Open Mercato product references, no hard-coded base branch or package manager (the lint gate greps for these). All tracker state management goes through named tracker operations, never direct gh commands (only references/trackers/ may contain them). Config values (baseBranch, paths, labels, validation commands) always come from .ai/agentic.config.json, never hard-coded. New om-auto-* skills MUST implement the Cross-skill contract. |
| Cross-skill contracts (tracker operations, config schema, Progress format, harness review/staging formats) | skills/om-setup-agent-pipeline/SKILL.md, skills/om-setup-agent-pipeline/references/trackers/TEMPLATE.md, skills/om-harness/references/, BACKWARD_COMPATIBILITY.md |
Multiple skills parse each other's outputs (execution-plan Progress sections, test-env.json, tracker descriptors, model review results, staged handoff markers). Changing a shared format requires updating every consumer in the same PR. Model/binding facts additionally live in skills/om-setup-agent-harness/references/configuration-template.json, provider-catalog.md, skills/om-harness/README.md, UPGRADE_NOTES.md, and this repo's README.md — update them together. |
Installer / tooling scripts (scripts/*.sh, scripts/*.mjs) |
package.json, the script itself, .github/workflows/ |
Keep scripts POSIX-portable where they run in CI (ubuntu) and locally (macOS). scripts/lint.sh is the CI gate — changes to it change what every PR must pass. |
CI workflows (.github/workflows/*.yml) |
scripts/lint.sh, scripts/audit-skills.sh |
lint.yml runs the frontmatter + product-agnosticism gate on every PR. skills-audit.yml is informational (skills.sh third-party audit surfacing). |
| Process / pipeline configuration | .ai/agentic.config.json, SDLC.md, .ai/trackers/github.md, skills/om-setup-agent-harness/SKILL.md |
Config and SDLC.md describe the same process — change them together. The optional agentHarness object is additive and managed by its separate setup skill. |
| README, DECISIONS.md, LICENSE | DECISIONS.md |
These MAY reference the upstream Open Mercato project (the agnosticism gate is scoped to skills/** only). Read DECISIONS.md before proposing structural changes — most "obvious" restructurings were already considered and decided. |
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.
