- Added a new `scrubProcessEnv` helper in `procmgr` to remove macOS malloc logging variables from `process.env` before spawning.
- Invoked the helper at coding-agent CLI startup so bun sub-processes no longer inherit the problematic environment.
- This prevented the recurring `MallocStackLogging` warning from appearing in child process stderr output.
- Added `readSseEvents` and `ServerSentEvent` exports in utils for reusable SSE stream parsing.
- Replaced Anthropic's local SSE parser with shared `readSseEvents(response.body, signal)` decoding.

- Expanded stream tests for `readSseEvents` parsing of CRLF, comments, split UTF-8 chunks, and trailing events.
listClaudePluginRoots accepts a home parameter so callers (and tests)
can override the base directory, but the OMP registry path was constructed
via getPluginsDir() which always reads the global dirs resolver anchored
to os.homedir(). This caused every test that passed a temp dir as home to
receive the real user registry alongside the test fixture, producing
length mismatches (+1 root in every assertion).
Fix: add an optional home override to getPluginsDir(). The override only
short-circuits the resolver when home differs from RESOLVER_HOME (the
os.homedir() value captured at module load, i.e. what dirs is anchored
to). Production callers that pass os.homedir() match RESOLVER_HOME and
still go through the XDG-aware resolver, preserving read/write coherence
with the marketplace writer and the cache invalidator. Tests passing a
temp HOME mismatch and short-circuit to <home>/<configDir>/plugins for
deterministic isolation.

- Standardized tool prompt example formatting by replacing `<example>` blocks with unified `<examples>` sections.
Codex code review flagged that external templates copied from pre-rename
versions of the repo still reference the misspelled SECTION_SEPERATOR
helper. Despite pi-utils compiling with `strict: false`, Handlebars
still throws "Missing helper" on unknown helpers in that mode
(verified: `strict: false` only silences missing context variables,
not missing helpers), so renaming alone would break live user configs
at render time.
Registers the legacy `SECTION_SEPERATOR` name as a second alias to the
same implementation so both spellings render identically. The canonical
spelling `SECTION_SEPARATOR` is used in all in-tree templates; the
alias exists purely for backward compatibility with external templates.
Further compresses packages/coding-agent/src/prompts/system/system-prompt.md
from 21,530 B to 16,545 B (−23% on top of the prior compression;
−9,060 B / ~−2,265 tok per turn vs origin/main) while restoring
RFC 2119 weight on every inviolable rule and reorganizing the
pre-yield discipline.
system-prompt.md
RFC 2119 keyword restoration
All rules under `# Contract`, Procedure §§2/6, and the tail `<critical>`
block use `**MUST**` / `**MUST NOT**` keywords that the file's preamble
pins to RFC 2119. The previous draft had downgraded 29 of these to
`Do **NOT**`, which reads as below-MUST-NOT against the same preamble.
Restored sites:
- `# Contract` — all 7 inviolable bullets
- `<critical>` tail block — all 4 safety rules
- `## 6. Verification` — mock ban and no-proof yield rule
- Procedure §2 — "search for existing examples" rule regains the
PROHIBITED parallel-convention clause it lost
- `<dir-context>` — AGENTS.md read requirement regains MUST
Structural dedup
- `<source-of-truth>` and `<instruction-priority>` were two priority
lists with overlapping scope. Merged into a single
`<instruction-priority>` covering all 5 conflict-resolution levels.
- `<self-check>` and `<scope-check>` were two pre-yield checklists;
`## 6. Verification` also had a third numbered "Before yielding,
verify..." list with overlapping checks. Collapsed all three into
one `<pre-yield-check>` section (incl. "output format matches the
ask" from the old verification list). `## 6. Verification` now
focuses on verification discipline (test rigor, mocks, run-scope).
Signal restoration
Added four anchors to `<design-checklist>` that were dropped from the
earlier `<code-integrity>` block and had no home in the new structure:
- Adversarial-caller / tired-maintainer self-questioning
- Cost-of-easy-path framing
- Inhabit-the-call-site self-review
- Persistence on hard problems (do not punt half-solved work)
Handlebars fix
The `### Tool priority` header was emitted unconditionally but its
body was wrapped in `{{#ifAny python|bash}}`, producing a bare heading
with no content when neither tool was available. Header now sits
inside the conditional.
SECTION_SEPARATOR helper relocation
The `SECTION_SEPARATOR` Handlebars helper is a generic section-header
formatter that was registered in coding-agent's
`config/prompt-templates.ts`. This coupled every template consumer to
a side-effect import of that module; a prior fix added
`import "./config/prompt-templates"` to `system-prompt.ts` so the
`/system-prompt` sub-path export would register the helper, but
sibling consumers (`task/executor.ts`, `task/template.ts`) worked only
by accident because the parent agent happened to load
`system-prompt.ts` first.
- Moved `sectionSeparator` function and helper registration to
`packages/utils/src/prompt.ts` next to the other generic helpers
(`xml`, `codeblock`, `ifAny`, `includes`, `not`, `jsonStringify`).
- `packages/coding-agent/src/config/prompt-templates.ts` now
re-exports `sectionSeparator` from `@oh-my-pi/pi-utils/prompt` for
the test that imports it via the coding-agent path.
- Removed the side-effect import from
`packages/coding-agent/src/system-prompt.ts`.
Template typo fix
Also fixes a latent `SECTION_SEPERATOR` spelling (→ `SECTION_SEPARATOR`)
in the two subagent templates (`subagent-system-prompt.md`,
`subagent-user-prompt.md`). Before the move the typo was masked
because every call site and the helper shared the wrong spelling.
Post-move, the helper is canonical `SECTION_SEPARATOR` in pi-utils
and all templates match.

* feat(utils): full XDG Base Directory support for all path helpers
Implement XDG-first resolution across all omp path helpers, extend the
migration command to cover every data/state/cache location, and fix
five data-safety issues found in review.
dirs.ts:
- Add getXdgCachePath() helper ($XDG_CACHE_HOME/omp/<subpath>)
- Add isDefaultAgentDir() helper: XDG lookup is only valid when the
resolved agentDir equals the process default (~/.omp/agent); custom
profiles set via PI_CODING_AGENT_DIR or setAgentDir() are never
silently redirected to the global XDG database
- Update 15 functions to XDG-first resolution:
data: getPluginsDir, getRemoteDir, getRemoteHostDir, getPythonEnvDir,
getWorktreeBaseDir
state: getReportsDir, getSshControlDir, getCrashLogPath, getDebugLogPath
cache: getPuppeteerDir, getGpuCachePath, getNativesDir
- Guard XDG lookup with isDefaultAgentDir(agentDir ?? getAgentDir()) in
all 9 agent-subdir helpers so that callers passing the global default
agentDir still resolve to the migrated XDG location, while callers
passing a non-default agentDir or running under a custom profile via
setAgentDir() bypass XDG entirely
- Plugin-derived helpers delegate to getPluginsDir() and follow XDG
resolution automatically
migrate-xdg.ts:
- Add getXdgCacheHome() helper
- Extend MigrationItem.category to include 'cache'
- Add 12 new migration entries: reports, plugins, remote, ssh-control,
remote-host, python-env, puppeteer, wt, gpu_cache.json, natives,
omp-crash.log, omp-debug.log
- Refuse to run when PI_CODING_AGENT_DIR points to a non-default
profile: migration only makes sense for the default ~/.omp/agent tree
- copyDirectory returns skipped source paths (target existed, non-force)
- verifyIntegrity: remove size-mismatch early-return that masked stale
targets as successful copies
- executeMigration: delete only entries that were actually copied;
use rmdir on source dir so it is removed only when empty, preserving
any skipped files for a subsequent --force run
- executeMigration: rename partial target to <target>.bak on integrity
failure instead of deleting; preserves pre-existing user data while
preventing getXdgDataPath from treating the partial tree as
authoritative; source remains intact for re-copy on next run
test isolation:
- Set XDG_DATA_HOME/XDG_STATE_HOME to non-existent paths in
memories-runtime.test.ts beforeEach/afterEach to prevent
getXdgDataPath/getXdgStatePath from resolving to real user data
* fix(utils,coding-agent): fix XDG support issues
dirs.ts:
- Refactor path resolution into DirResolver class. XDG base dirs are
resolved once at construction from env vars (Linux only, no
existsSync). setAgentDir creates a fresh instance, naturally
invalidating all cached paths and recomputing isDefaultProfile.
- getRootSubdir/agentSubdir accept optional XdgCategory parameter;
when set, the XDG base replaces the config root. Every accessor
is a one-liner delegate.
- Non-Linux platforms: XDG fields are null, zero overhead. No
filesystem probing, no string comparisons on the hot path.
- Config-only subdirs (themes, tools, commands, prompts, modules)
have no XDG category — they stay under the config root.
- Remove `import { env } from 'bun'`, use process.env consistently.
- Restore JSDoc comments to document actual defaults (~/.omp/...).
migrate-xdg.ts:
- Gate migrateToXdg on Linux — exits with clear error on other
platforms.
- Fix data loss bug: verifyIntegrity now accepts a Set of skipped
paths and skips verification for files that were intentionally not
copied (pre-existing at target in non-force mode).
- Fix nested directory source deletion: recursive removeSourceEntries
walks the tree and only deletes files not in the skipped set.
- Remove dead _sourcePath variable and unused force parameter from
verifyIntegrity.
- Remove `import { env } from 'bun'`, use process.env consistently.
logger.ts:
- Revert JSDoc to document ~/.omp/logs/ as default.
oauth.ts:
- Replace direct getAgentSubdir call with getTestAuthPath().
CHANGELOG.md:
- Merge duplicate section headers under [Unreleased].
- Add missing blank line before [13.11.1].
