Archon is a workflow engine for AI coding agents that turns development processes into YAML-defined sequences with phases, validation gates, and artifacts. Developers use it to run repeatable processes such as planning, implementation, testing, code review, and pull-request creation across projects. The catalogue entries provide commands, agents, skills, hooks, instructions, and settings for working with Archon.
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 5.1 | $0.00000 | $0.00662 |
| Opus 5.5 | $0.00000 | $0.00265 |
| Sonnet 5.5 | $0.00000 | $0.00132 |
| Haiku 4.5 | $0.00000 | $0.00066 |
Grade A, and why
discover-checks 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 — 27 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Discover the checks
Find the project's own checks and declare them. You do not run the gate: a script runs exactly what you declare, for as long as it takes, and records every exit status. Your declaration is the whole of what gets validated, so it must be the project's gate and nothing else.
Optional narrowing (may be empty — empty means the full applicable gate):
$INPUTS.scope
The run's trigger message, which may add context:
$ARGUMENTS
Discover
- Read the checks from the repository itself: package scripts, task runners, CI workflow definitions, contributor docs. Never invent a generic command the project does not define; never substitute your own idea of a check for the project's.
- Honor a documented aggregate gate (a
validate/checkscript) over reassembling its pieces by hand. Declare it as one check in one group. Declare separate checks only when the project has no aggregate gate, and then in the project's own order where one is documented: type checks, lint, tests, build. - Find the independent gates. A project with several independently built parts — a service in one language beside a web app in another, per-module or per-crate gates — has one group per part, so a failure in one never hides another's results. Checks that belong to one gate share a group, in order.
- If dependencies are missing, declare the project's own install command in locked mode as the first check (for example a frozen lockfile flag). A gate that fails on a broken environment is reporting the environment, not the code.
- Apply the narrowing above when it is not empty: the checks that cover that package, directory or named check.
You may read files and run read-only commands to find these out — list scripts, check whether dependencies are installed, inspect git status. Do not run the checks themselves, and do not modify anything.
Declare
checks— each check as{ name, argv, group }, in the order to run.argvis the command and its arguments as separate strings, run from the repository root with no shell. When a check genuinely needs a shell (a pipeline,&&, an environment assignment), name the shell explicitly, as in["bash", "-c", "<the project's own command>"]. On Windows, a command installed as a.cmdshim (such asnpmorpnpm) also needs a shell to start.groupnames the independent gate the check belongs to; within a group order matters and the first failing check ends that group, while every group runs. A project with one gate puts every check in one group. An install step goes first in each group that needs it, so a failed install stops exactly the gates that depend on it; a locked install that already holds is quick to repeat.notes— one or two sentences: where the gate is defined and why these checks. When the repository genuinely defines no checks,checksis empty andnotessays what you looked at to establish that. An empty list reads as green, so declare it only when there is truly nothing to run, never because the gate looked hard to run.
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.

discover-checks is a command published in the GitHub repository coleam00/Archon (23,690 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 662 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 2026-09-26.
