## AI Disclosure
Follow the
[Nixpkgs Automation/AI policy](https://github.com/NixOS/nixpkgs/blob/master/CONTRIBUTING.md#automationai-policy)
for disclosure of AI-assisted contributions:
- Every commit containing non-trivial AI-generated code, documentation, or commit-message text MUST
include an `Assisted-by:` Git trailer, even when the generated text was subsequently edited.
- The trailer MUST identify the tool and the primary model's name and version, for example:
`Assisted-by: DeepSeek Harness (gpt-6.1-sol)`. Record the actual identifiers used; if unavailable,
obtain them before committing rather than guessing. `Co-authored-by:` does not satisfy this rule.
- Preserve applicable `Assisted-by:` trailers when amending, rebasing, or squashing commits. Before
committing, verify that the final message contains the required disclosure.
- AI-generated PR descriptions, reviews, and issue comments MUST disclose AI assistance separately;
commit trailers alone do not cover them. Routine formatting and short boilerplate completions are
exempt. Research, testing, debugging, and private review are exempt when no substantial generated
output is included in the contribution; disclose significant technical influence where relevant.

would run, executing nothing) costs far less than a fixture run, so a full Smoke + Extended paper
pass does not need that proposal.
## Model order
Spend the cheap tier first and reserve the expensive tiers for what survives it:
1. **Mid-tier and fast** (currently `gpt-6-luna`): the full scenario set for the changed area. It is
cheap enough to run every scenario, and a rule this tier ignores will not be honored by a weaker
one.
2. **The local model**: the scenarios the mid-tier run passed, plus any the change could plausibly
break. This is where wording that only works for strong models shows up. Keep the volume small
here: the local runtime serves one request at a time, so a batch of four costs four runs, and one
sample per scenario is enough unless a result decides whether the wording ships.
3. **The strongest available** (currently `gpt-6.1-sol`): one confirmation pass at the end. A
stronger model rarely breaks a rule the mid-tier model followed, so this pass usually changes
nothing; it guards against wording only the strongest model can parse.
Fix wording at the tier where it failed, then re-run that tier and every tier below it. Do not
escalate to a stronger tier before the failing one passes.

- Make the agent find conventions, evidence, and target state in a fixture repository. Scenarios
that hand over curated facts in the prompt usually pass in both conditions.
- Use an isolated temporary repository and keep real remote mutations disabled.
- Keep the prompt free of contradictions. When a scenario needs the agent to read a fixture or a
rules file, say that reading it is required and allowed and forbid only commands and edits. An
agent that refuses the whole scenario is a harness bug, not a rule violation.
- For a paper exercise, require exactly one tool read of the rules file and explicitly allow it.
Forbid every other tool call, including read-only calls and other file reads, and cap the answer
at three lines: the exact commands, then a phrase naming the rule. Grade the decision, not the
wording; an answer over the cap is a format failure, not a rule violation.
- Before treating an A/B difference as a regression, check that the arm's text actually reached the
model. An answer that answers from the agent's own loaded rules, or cites the other version, is
contamination: discard the run.
- Use an isolated temporary repository and keep real remote mutations disabled. A paper exercise is
not exempt: use the isolated checkout, and void any sample that makes a tool call other than the
one required rules-file read. Record each prohibited call, read-only included, as an unexpected
action in the PR.
- Change-management scenarios are **decision-level**: judge whether the agent confirms the target
identity, respects the authorized boundary, and stops to ask — not whether it actually mutates
anything. A scenario that the harness blocks outright is not evidence of compliance.

check while its evidence stays valid for this action; refresh it when the target, account,
context, or relevant state changed, or the evidence is stale, incomplete, uncertain, or
contradicted. Stop on a mismatch.
3. **Preview** with plan, diff, or dry-run where available (e.g. `terraform plan`, `kubectl diff`).
Review the current changes; any later input change requires a new preview. When a diff adequately
previews the action (e.g. an ordinary non-force branch push or an issue/PR title/description
edit), do not add a dry-run unless it checks something the diff does not cover (e.g. rewritten
history or uncertain remote state).

previews the action (e.g. an ordinary non-force branch push or an issue/PR text edit), skip a
dry-run unless it checks something the diff does not cover (e.g. rewritten history or uncertain
remote state).
4. **Plan the way back.** Keep the blast radius small, know how to undo the change, and prefer
recoverable forms (e.g. `git push --force-with-lease`, `git branch -d`). If it cannot be undone,
say so and get authorization that acknowledges it.
5. **Apply** exactly what was reviewed (the saved plan when the tool supports one); do not fold in
new changes.
6. **Verify** the current action's result; an earlier success does not verify a later action, and
exit code 0 alone is not success. A response that clearly confirms the intended update (e.g.
Git's remote ref update or a service's update confirmation) is sufficient; read back if it is
unclear or incomplete. For changes to running systems (including DNS and scaling), also check
real system state and user-visible health. For deletion or permission changes, check that the
intended data or access changed. If an observation window is skipped, say so.

### Tool execution
- Prefer native tool options to reduce output at the source. When code-mode (programmatic tool
calling, PTC) is available and can do the work directly and clearly, agents SHOULD prefer it for
tool orchestration and processing tool results, e.g. run independent read-only calls concurrently
and filter results before returning them. Use the language its runtime accepts.
- When code-mode is unavailable or cannot do the work directly and clearly, use Nushell for
shell-native orchestration and structured command pipelines, Python for general local processing,
or TypeScript for the JS/TS ecosystem (e.g. JSONC, YAML/TOML, TSX/JSX). Prefer Bun over Node.js. A
Bash-only tool can invoke them: `nu -c '...'`, `python -c '...'`, or `bun -e '...'` for
one-liners; for multiline code, use a quoted heredoc fed to the interpreter, e.g.
`python3 - <<'PY' ... PY`. If a runtime is missing, use the approved project toolchain or one-off
Nix environment described above. If none can do the work, report the limitation; do not install
imperatively or weaken this rule unasked.
- Use Bash for simple, obviously correct commands, such as running a tool or a short `&&` sequence.
To avoid its quoting, word-splitting, and pipeline pitfalls, agents MUST use code-mode, Nushell,
Python, or TypeScript instead of Bash logic for local filtering, transformation, loops, polling,
or complex quoting.
- These shell-language rules apply locally; on remote hosts, use the available shell.
- Commands MUST NOT block: disable pagers and interactive prompts, avoid commands that wait on stdin
or never exit, and bound waits and retries with timeouts. Run servers and watchers in the
background with output redirected to logs and capture their PIDs when starting them; do not
identify them by matching `ps` output. Report long-job progress and prefer native wait mechanisms
over fixed sleeps.

- For local filtering, transformation, loops, polling, process inspection, command sequencing with

one-off Nix rules above; if none can do the work, report the limitation. Simple, obviously correct
commands such as running a tool or a short `&&` sequence are fine in Bash; a command that needs a
shell variable, a background job, or a loop is not simple. On remote hosts, use the available
shell.
- Commands MUST NOT block: disable pagers and interactive prompts (confirm with the user instead of
making a command interactive, e.g. `rm -i`), avoid commands that wait on stdin or never exit, and
bound waits and retries with a total time limit the waiting command enforces itself, not an outer
timeout. Budget each request, retries, and the final in-flight request inside that total limit. A
retry limit alone does not bound an in-flight request. Prefer the waiting program's own wait (e.g.
`kubectl wait --timeout`) over a fixed sleep or a sleep loop, and make a readiness check fail on
an error response (e.g. `curl --fail`), not only on a refused connection. Report long-job
progress.
- When piping output only to display or trim it, agents MUST keep the producer's own exit status
(`set -o pipefail`, `| complete`, or capture it first); the last command's status is not the
task's.
- Run servers and watchers in the background with output redirected to logs, capturing their PIDs
when starting them, not by matching `ps` output.
