Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

What it costs to keep this loaded
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 | $0.00053 | $0.01074 |
| Opus 5.5 | $0.00021 | $0.00430 |
| Sonnet 5.5 | $0.00011 | $0.00215 |
| Haiku 4.5 | $0.00005 | $0.00107 |
Grade A, and why
autonomous-run 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 9d 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 — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Autonomous run — bounded overnight execution
This skill is for a finite approved implementation, not a recurring watcher. For recurring work use the autonomous-loops profile. For unresolved product or architecture decisions, run Wayfinder first.
Hard gate
Do not begin implementation unless all of these are true:
- The terminal spec is committed under
docs/specs/withstatus: accepted,accepted_by, andaccepted_at. An agent may author onlystatus: draft. - A separate implementation-ticket ID is named. The decision ticket is not executable work.
- The operator explicitly invokes or authorizes
start. Producing or checking a spec never self-authorizes implementation.
Linear and every other external system still follow the installed write-consent rule. The v1 controller has no external-write adapter at all.
Prepare the contract
Use .agentsmith/autonomous-run.py in an installed project; the source checkout uses
scripts/autonomous-run.py. The installed template is
.harness/templates/autonomous-run.json (the harness source checkout uses
templates/autonomous-run.json):
python3 .agentsmith/autonomous-run.py prepare --run-id <short-id> --spec docs/specs/<name>.md --ticket <implementation-ticket> --maker codex --checker claude --template .harness/templates/autonomous-run.json
This creates a non-executable draft until both roles have explicit model and effort settings.
Review its exact allowed/denied paths, verifier, models, attempt cap,
wall-clock limit, budgets, and optional scope.resources keys such as port:3000 or
db:local/test. Resource keys coordinate cooperating local runs; they do not replace operating-
system port binding or database isolation. Commit the manifest before execution; the controller
refuses an uncommitted contract. Concurrent worktrees share writable Git metadata needed for local
commits, so this guard prevents accidental collisions between cooperating runs; it is not a
security boundary for mutually untrusted makers.
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.

autonomous-run is a skill published in the GitHub repository PromptPartner/agentsmith (178 stars, last pushed 7d ago), licensed MIT. It adds 53 tokens to every session and 1,074 once invoked, about $0.0002 per session on Opus 5.5. 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.
