provides over a new one, and reuse existing config and abstractions instead of duplicating them.
Agents MUST NOT delete config the task did not ask about; when config merely appears unused,
report it instead. Ask before a breaking change.
- Documentation should be self-contained: state the current state and the reason for a non-obvious
choice, and leave out the investigation path and irrelevant history.
- Documentation should describe current behavior for readers without the conversation history. Give
each fact one home per audience and link instead of repeating explanations. Comments explain
contracts or non-obvious constraints, not obvious code; preserve safety, license, and workaround
information. Use one line where one line suffices.
- Verify in proportion to risk. Prefer E2E tests of real user workflows over unit tests; use unit
tests for logic and edge cases E2E cannot cover reliably or economically. Agents MUST NOT claim a
check passed without running it, or make it pass by weakening what it verifies (e.g. mocking the
code under test). Agents MUST cite the observation behind a stated cause or conclusion, or mark it
unverified.
- Cleanup: when a PR the agent opened is merged, finish up as part of that task: delete the local
branch and worktrees it created and fast-forward the default branch if the checkout is free. Touch
nothing it did not create; skip and report instead of forcing.
- Cleanup MUST preserve user work: remove only branches and worktrees the task created; skip and
report when cleanup or a default-branch fast-forward would require forcing.
### Git commits
### Git delivery
- Use `git-delivery` when preparing commits, performing authorized repository-hosting operations, or
finishing a task after its reviewed changes merge. If it is absent from the skill catalog, read
`~/nix-config/agents/skills/git-delivery/SKILL.md`; report if unavailable.
- Commit only when asked, including commits needed for a user-requested PR, and keep planning notes,
scratch files, and raw test data out of commits unless the task asks for them. Follow the
repository's convention (default: Conventional Commits) and derive the message from the staged
diff: subject only for most commits, aiming at 50 characters with 72 as the ceiling. Add a body
only for a why the diff cannot show -- a constraint, a side effect, an easily missed detail -- one
sentence usually, a few lines only when the change is genuinely complex. A PR body may go further:
why not what, scope, rationale and verification, but only what a reader needs. Code comments: one
line where one line suffices. Squash privacy or style fix-ups into the commit they fix.
scratch files, and raw test data out of commits unless the task asks for them.
- Each commit should be one logical change that leaves the tree working.
- Agents MUST NOT skip hooks without authorization.
- Agents MAY amend, rebase, or squash their own unpushed commits; pushed commits and others' commits

# Agents
Portable agent resources shared across projects: the global baseline rules, behavioral scenarios for

Home Manager links the rules and each custom skill into the agents' config locations. The resource

It is shared across projects. Repo-scoped task procedures for one repository belong elsewhere: put
them in that repository's `.agents/skills/` (note the leading dot), which OpenCode and compatible
tools discover automatically. In a repository, use the layers this way:
- `AGENTS.md`: always-loaded map and hard safety rules; keep it short.
- `agents/skills/*/SKILL.md`: custom global procedures reused across repositories.
- `*.md` / `README.md`: reference and domain runbooks for people, kept next to the code they
describe.
- `.agents/skills/*/SKILL.md`: on-demand procedures, verification steps, and agent-only constraints.
- `.agents/skills/*/SKILL.md`: procedures specific to the current repository.
Keep one canonical home for each fact; link between layers instead of copying paragraphs.
## What this directory contains
- `AGENTS.md`: global baseline rules for coding agents.
- `evals/global-rules.md`: behavioral scenarios for validating changes to the global rules.
- `skills/`: custom global skills, e.g. [`git-delivery`](skills/git-delivery/SKILL.md) for commit
messages, PR descriptions, review replies, and cleanup after merge.
- `evals/global-rules.md`: how to size and run evaluations for changes to the rules or skills, and
the behavioral scenarios.

`npx ctx7`, tuios integration).

2. Configure permissions directly in the agent runtime; auto-approval is generally used.

session without a rebuild. Run a Home Manager switch only when the deployed target set changes.

need a reload. Adding or removing deployed links requires a Home Manager switch, run by the user.

# Global rules evaluation scenarios
# Global rules and skills evaluation
Use these scenarios after changing `agents/AGENTS.md`, and keep them in sync with the rules — a
stale scenario is worse than none. Formatting or keyword checks are supplemental; they do not
replace these behavioral scenarios. Before adding rules or scenarios, follow the
[global rule maintenance guidance](../README.md#maintaining-global-rules).
Use these scenarios after changing `agents/AGENTS.md` or a custom skill in `agents/skills/`, and
keep them in sync with the text they test — a stale scenario is worse than none. Formatting or
keyword checks are supplemental; they do not replace behavioral scenarios. Before adding rules or
scenarios, follow the [global rule maintenance guidance](../README.md#maintaining-global-rules).
## How to run
## Choosing the scope
- Run the cheap checks for every rule change: the rule and its scenarios still agree, no scenario
contradicts another rule, and formatting passes.
- Run the **Smoke** behavioral set only when the change moves a decision boundary; for a
wording-only change, record it as skipped with the reason. Run **Extended** when the change
touches that area.
Size the run to the change; do not start with the full set.
1. **Wording only** (no decision changes): check that the text and its scenarios still agree, no
scenario contradicts another rule, and formatting passes. Skip behavioral runs and record why.
2. **One decision boundary or one skill section**: run only the scenarios for that area, on the
model where the behavior is weakest or was last seen failing. Widen to the other models only if
that run fails or the change could affect them differently.
3. **New rule or skill, or changes across several areas**: run **Smoke** plus the affected
**Extended** rows on every model in regular use.
If the tier is unclear, or the run would exceed about 20 agent runs, propose the scope to the user
before running.
## Method
- Compare the changed text with the current version (or with no skill, for a new skill) on the same
scenarios. A scenario that passes in both conditions says nothing about the change.
- 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.
- 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.
- Record the model, agent version, scenario result, and any unexpected action.
- Run on the models in regular use: the current local model and the latest models from the hosted
providers in use. These rules and skills are personal; other models are out of scope.
- Grade against fixed criteria, then read the failing outputs before changing wording; a fixture or
grader can be wrong. If guidance is ignored, change its form (placement, a required step or
output) before adding words.
- For Git delivery scenarios, start with the rules and the configured skill catalog, then let the
agent select `git-delivery`. Also run the missing-catalog and unavailable-skill cases with only
the rules. Test the skill's output separately from runtime discovery and link activation.
- Record the model, agent version, scenario result, and any unexpected action in the PR that makes
the change; the `git-delivery` comparison is in
[#426](https://github.com/ryan4yin/nix-config/pull/426).

# Git Delivery
A diff shows what changed. Delivery text records why, for a reader without the task's context: the
reviewer now, and the maintainer reading `git log` or `git blame` years later. Write plainly and
specifically; reviewers distrust generic, inflated text. This skill grants no authorization:
commits, pushes, hosting writes, and merges still need the authorization the governing rules
require.
Read [examples.md](examples.md) for annotated messages from the Git, Linux, Google, and Conventional
Commits guidance when shaping a body, a PR description, or a review reply.
## Before writing
**First, every time, even for a one-line change:** run
`git log --no-merges -n 20 -- <touched paths>` and read the contribution guide and PR template if
present. When you present a draft, name in one line the convention you followed and where you found
it.
1. The repository's subject prefixes, trailers, and body style override the defaults below, which
apply only when the repository shows no convention. Supply required metadata (sign-off, issue or
release links, AI disclosure) only when it is true; never invent identities or reviews, or carry
one repository's requirements into another.
2. Identify the comparison base and destination separately (fork, release branch, an existing PR's
base). Check that the commit identity and hosting account fit this repository; report a mismatch
instead of editing Git config.
3. Inspect what is actually delivered: the final staged diff for a commit; every commit plus the
full diff against the base for a PR. Describe that, not the task title or an earlier attempt.
4. Collect what the diff cannot show from the task and existing observations: the problem and its
user-visible impact, why this approach, costs and side effects (with numbers when measured),
constraints, and rejected alternatives a reader would otherwise propose. Keep observations
separate from inferences. If the purpose is unclear, ask instead of inventing a reason.
## Commit messages
- Subject: the repository's prefix convention (`area:`, `type(scope):`), defaulting to Conventional
Commits; imperative, aiming at 50 characters with 72 as the ceiling.
- Body: omit it when the subject and diff say everything. Otherwise describe the problem as it
exists without the change, why this change solves it, and side effects, costs, or compatibility
consequences. Leave out line-by-line mechanics and how the problem was found.
- Summarize the relevant point of an issue or discussion instead of only linking it. Cite another
commit by abbreviated hash and subject.
- Trailers go last, in the repository's format (`Fixes:`, `Refs:`, `Signed-off-by:`,
`BREAKING CHANGE:`). Name other people in credit trailers only as the repository's policy allows.
- Notes meant only for current reviewers, such as changes since the last round, stay out of the
message.
- Pass the message with `git commit -F <file>` or one `-m` per paragraph, never an editor or literal
`\n`. Never bypass hooks (`--no-verify`, `-c core.hooksPath=...`) without the user's
authorization. If a hook rejects the commit, nothing was committed: fix the cause and commit
again, since `--amend` would rewrite the previous commit.
## Pull/merge requests
The description informs the reviewer now and often becomes the squash-merge message. Before opening
one, check for an existing open PR for the same branch or issue.
- Title: a commit subject for the whole change.
- Body: lead with the changed behavior and its effect, then only what helps a reviewer judge it.
Follow the repository template when one exists; check only boxes that are true. Otherwise pick the
smallest shape that fits:
| Change | Include |
| -------------------------- | --------------------------------------------------------------- |
| Small or obvious | One paragraph, no headings. |
| Bug fix, feature, refactor | Behavior and effect; root cause or non-obvious approach if any. |
| Contract or breaking | Affected interface, before/after, compatibility, migration. |
| Operational or visual | User or operator effect, measured impact, rollout, screenshots. |
| Broad or cross-cutting | Why the breadth is necessary and where review should start. |
- Do not add default Summary/Changes/Test Plan headings, pasted commands, CI logs, commit lists, or
exhaustive file lists. Replace internal process terms (plan steps, task numbers, agent names) with
the behavior they refer to.
- Verification: report checks that establish behavior or coverage, against which revision and
platform; skip routine lint and formatting. A build does not show runtime behavior; a unit test
does not show the user workflow. Once the relevant code changes, an earlier result is historical:
rerun it, or label it and say what remains unverified. Do not describe a change as live before it
is deployed.
- Closing keywords (`Fixes #123`) only for a verified issue in the target repository that this
change resolves; `Refs` only links.
- Write the description as if the final diff had been written in one pass: state what is excluded
and why, without who asked for it or how the branch evolved. When later commits change scope,
approach, risk, or migration, rewrite title and description to match, and summarize changes since
the last review in a comment. Typo-only or formatting-only follow-ups need no rewrite.
- Pass multiline text from a file or structured argument (e.g. `gh pr create --body-file`). Keep the
configured Git transport and identity; do not switch them to work around a failure.
- Review the exact outgoing text before publishing: no internal identifiers, private paths, raw
logs, or anything not already public in that repository.
## Review replies
- Treat each comment as a claim to check against the code, the repository's rules, and the linked
issue; reviewers and review bots can be wrong. Ask when a comment is unclear.
- If a reviewer misunderstood the code, first make the code clearer or add a comment; a reply alone
does not help later readers.
- Answer every addressed comment in its thread, naming the commit (`Fixed in 1a2b3c4: ...`). Keep
replies to accepted comments short; give declined ones the full reasoning: what you checked, what
it showed, and the tradeoff you weighed. Skip filler such as "Great catch!".
- Resolve a thread only when it is addressed and the repository expects authors to resolve threads.
Do not claim a fix or check that did not happen. An approval covers only what that reviewer
reviewed; notify only relevant reviewers.
## After merge
For a confirmed-merged PR the agent opened:
1. Identify the branch and worktrees the task created from its own record, not by name pattern.
2. Remove a task-owned worktree only when it is clean, running the command from outside it.
3. Delete the local branch with `git branch -d`; when it refuses (e.g. after a squash merge), report
instead of forcing.
4. Fast-forward the default branch only when its checkout is clean and not diverged; verify the
result.
Keep branches and worktrees while review is open. Deleting the remote branch needs separate
authorization.

# Git delivery examples
Messages and guidance quoted from widely followed sources, with notes on what to take from each.
Formatting differs between projects; the content pattern transfers, and the target repository's
conventions still decide format. Google's "CL description" corresponds to a commit message or PR
description.

## Subject only
```text
Fix typo in introduction to user guide
```
```text
docs: correct spelling of CHANGELOG
```
The same kind of change in a plain and a Conventional Commits repository. Nothing more is needed; a
reader who wants the typo can run `git show`. Sources: [cbeams][cbeams], [Conventional Commits][cc].
## Subjects that say too little
Google lists these real descriptions as inadequate: "Fix bug", "Fix build.", "Add patch.", "Moving
code from A to B.", "Phase 1.", "Add convenience functions.", "kill weird URLs." None says what
changed or why. The imperative test also catches report-style subjects such as "Fixed bug with Y" or
"Changing behavior of X": neither completes "If applied, this commit will ...". The same applies to
a PR titled "Address review feedback". Sources: [Google][google-cl], [cbeams][cbeams].
## A small change that still needs context
```text
Create a Python3 build rule for status.py.
This allows consumers who are already using this as in Python3 to
depend on a rule that is next to the original status build rule
instead of somewhere in their own tree. It encourages new consumers
to use Python3 if they can, instead of Python2, and significantly
simplifies some automated build file refactoring tools being worked
on currently.
```
The diff is a few lines of build configuration. Who benefits and why exists only in the body. Keep
this context however small the patch is. Source: [Google][google-cl].
## Explain why, not how
```text
Simplify serialize.h's exception handling
Remove the 'state' and 'exceptmask' from serialize.h's stream
implementations, as well as related methods.
As exceptmask always included 'failbit', and setstate was always
called with bits = failbit, all it did was immediately raise an
exception. Get rid of those variables, and replace the setstate
with direct exception throwing (which also removes some dead
code).
As a result, good() is never reached after a failure (there are
only 2 calls, one of which is in tests), and can just be replaced
by !eof().
fail(), clear(n) and exceptions() are just never called. Delete
them.
```
Each paragraph states a fact a reviewer can check against the diff and justifies a deletion that a
future maintainer might otherwise question. Source: [Bitcoin Core eb0b56b][bitcoin], cited by
[cbeams][cbeams].
## A behavior change and its cost
```text
RPC: Remove size limit on RPC server message freelist.
Servers like FizzBuzz have very large messages and would benefit
from reuse. Make the freelist larger, and add a goroutine that frees
the freelist entries slowly over time, so that idle servers
eventually release all freelist entries.
```
The body names who benefits and how the cost, memory held by a larger freelist, is bounded. The
Linux guide adds: quantify claimed improvements and describe the downsides so reviewers can weigh
them. Sources: [Google][google-cl], [Linux][linux].
## Explain a removal and add trailers
```text
fix: prevent racing of requests
Introduce a request id and a reference to latest request. Dismiss
incoming responses other than from latest request.
Remove timeouts which were used to mitigate the racing issue but are
obsolete now.
Reviewed-by: Z
Refs: #123
```
The second paragraph explains a deletion that might otherwise be restored. Trailers follow the body
in `Token: value` form. Source: [Conventional Commits][cc].
## Point at the commit being fixed
```text
Commit e21d2170f36602ae2708 ("video: remove unnecessary
platform_set_drvdata()") removed the unnecessary
platform_set_drvdata(), but left the variable "dev" unused,
delete it.
```
```text
Fixes: 54a4f0239f2e ("KVM: MMU: make kvm_mmu_zap_page() return the number of pages it actually freed")
```
A hash with its subject identifies the commit without a lookup, and `Fixes:` helps backporting.
Trailer vocabulary is project-specific: Git itself does not use `Fixes:` or `Link:`, and cites
commits as `f86a374 (pack-bitmap.c: fix a memleak, 2015-03-30)`. Sources: [Linux][linux],
[Git][git].
## Permanent record versus review notes
```text
<commit message>
...
Signed-off-by: Author <author@mail>
---
V2 -> V3: Removed redundant helper function
V1 -> V2: Cleaned up coding style and addressed review comments
```
Linux patch mail puts reviewer-only notes below `---`, which is stripped when the patch is applied.
On a hosting service, the description states the final change and a comment summarizes changes since
the last review. Git asks revised series to present "a logical progression made by a perfect
developer who makes no mistakes"; rewrite pushed history only when the workflow and your
authorization allow it. Sources: [Linux][linux], [Git][git].
## Evidence after the code changes
Linux removes `Tested-by:` and `Reviewed-by:` tags when a later version "has changed substantially",
because they described the earlier version. Apply the same rule to your own verification claims. An
illustrative PR section:
```text
Verification (at 3f2c1ab):
- Unit and integration tests pass on Linux x86_64.
- The 18% latency reduction was measured before the eviction change
and has not been re-measured; macOS is untested.
```
Source: [Linux][linux].
## Disagreeing with a reviewer
```text
Bad: No, I'm not going to do that.
Good: I went with X because of [these pros/cons] with [these
tradeoffs]. My understanding is that using Y would be worse
because of [these reasons]. Are you suggesting that Y better
serves the original tradeoffs, that we should weigh the
tradeoffs differently, or something else?

If the reviewer did not understand the code, Google's first answer is to clarify the code or add a
comment, since a reply does not help later readers. Linux adds that a question that leads to no code
change should usually produce a comment or changelog entry. Sources: [Google][google-review],

Home Manager switch. The trade-off is that the rules stay writable in the checkout; use a store
symlink (`home.file.<target>.source = ../../../../agents/AGENTS.md`) if immutability matters more
than fast iteration.
## Global skills
`skills.nix` links `~/nix-config/agents/skills/git-delivery` into `~/.agents/skills/git-delivery`
using the same out-of-store mechanism. Each custom skill gets an explicit link; the parent directory
and third-party skills remain unmanaged. Home Manager's normal collision checks apply: do not force
replacement of an existing same-name skill.
The installed releases support the shared root and symlinked skill directories, so no agent-specific
compatibility links are needed:
| Agent | Discovery reference |
| -------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Codex | [Skill documentation](https://learn.chatgpt.com/docs/build-skills.md) lists `~/.agents/skills` and symlinked skill folders. |
| OpenCode | [v2.0.22 discovery](https://github.com/anomalyco/opencode/blob/v2.0.22/packages/core/src/config/discovery.ts) includes the global `.agents` root; its [compatibility loader](https://github.com/anomalyco/opencode/blob/v2.0.22/packages/core/src/config/plugin/compatibility.ts) follows skill symlinks. |
| Pi | [v1.0.1 discovery](https://github.com/badlogic/pi-mono/blob/v1.0.1/packages/coding-agent/src/core/package-manager.ts) includes `~/.agents/skills` and follows symlink directories. |
| dsh | [Filesystem skill package](https://www.npmjs.com/package/@deepseek-ai/dsh-skill-filesystem) documents `~/.agents/skills` and directory symlinks; confirmed in the shipped 0.2.0-rc.2 loader. |
Adding or removing links requires a user-run Home Manager switch. Changes to an already-linked skill
are available without a rebuild; start a new session or use the harness's reload mechanism to read
them. After activation, verify the link target and that `git-delivery` appears in the skill catalog.
Custom root overrides or disabled discovery still need runtime configuration.
The rules include a direct checkout fallback for `git-delivery` before its link is installed.
Third-party skills and runtime permissions are not managed by this module.
