* fix(plugin): consolidate system prompt injections into single array element
The plugin previously pushes planning prompts and improvement contexts as
separate elements in the output.system array. This change appends them to
output.system[0] with newline separators instead. This keeps all system
instructions within a single message block to prevent potential parsing or
formatting issues when the agent processes the context.
* refactor(opencode-plugin): extract composeSystemPrompt helper to centralize system prompt assembly and add unit tests
* style(opencode-plugin): remove extra newline before plan submission reminder heading
* fix(opencode-plugin): store composed prompt result before clearing system array to prevent data loss
Previously, `output.system` was cleared with `length = 0` before being passed into `composeSystemPrompt`, causing the function to compose from an empty array instead of the original system content. The fix stores the composition result in a variable first, then pushes it after clearing. Additionally, add `.trim()` in `stripConflictingPlanModeRules` to normalize whitespace before filtering empty entries, and include a test case for empty string collapse behavior.
* refactor(plan-mode.ts): move string trimming from stripConflictingPlanModeRules to composeSystemPrompt for centralized whitespace handling
* test(plan-mode): add test case for trimming trailing newlines in composeSystemPrompt
* feat(submit-plan): replace text/file-path mode with edit-based interface
Switches the OpenCode submit_plan tool from a dual-mode interface
(inline text or file path) to an edit-based one. The plugin now owns a
backing file at .opencode/plans/_active-plan.md; the agent never reads
or writes it directly. On denial, the response includes the current plan
with line numbers so the agent can apply surgical edits instead of
resubmitting the entire document, reducing token waste on iterative
revisions.
- Add applyEdits, validateEdits, formatWithLineNumbers, and
getPlanBackingPath helpers to the plugin
- Validate edit ranges (bounds, overlap, size limit) before mutating the
backing file
- Return line-numbered plan in denial responses to anchor targeted edits
- Remove getPlanDirectory, validatePlanPath, and file-path auto-
detection from plan-mode.ts
- Replace plan-mode.test.ts path-validation coverage with submit-
plan.test.ts for the edit engine
- Update custom-feedback.md and opencode.md docs for edit-based
semantics

* chore(opencode): drop unused buildPlanFileRule import
Removed in PR #730 deny path along with the only call site, but the
import was left behind.

* fix: OpenCode plan mode permissions and prompt conflicts
- Add per-agent edit permission (*.md allow) for the plan agent via
opencodeConfig.agent.plan.permission.edit, fixing the path.relative
worktree mismatch that caused PermissionDeniedError on plan writes
- Strip OpenCode's "STRICTLY FORBIDDEN" plan mode prompt from synthetic
user message parts via experimental.chat.messages.transform
- Replace conflicting TodoWrite/planning instructions in the base prompt
when plan agent is active (surgical replacements + global sweep)
- Override todowrite tool description to redirect to submit_plan
- Enhance submit_plan tool description with planning workflow guidance
- Add system-reminder reinforcing plan mode behavior on every turn
- Disable validatePlanPath directory restriction (plans can be written
anywhere)
- Strengthen planning prompt with explicit anti-TodoWrite language,
required workflow summary, and mkdir instruction

* feat: extract checklist utilities to shared package
Move ChecklistItem, parseChecklist, extractDoneSteps, and
markCompletedSteps from Pi extension to @plannotator/shared

* feat: Pi-style iterative planning for OpenCode plugin
Rewrite the OpenCode plugin to match Pi's planning methodology:
- Inject rich iterative planning prompt when agent is "plan"
(explore → update plan → ask user loop, structured plan format)
- File-based submit_plan: reads plan from disk instead of requiring
it as a string arg. Resolves path from OpenCode's system prompt,
falls back to PLAN.md
- Suppress plan_exit via tool.definition hook (directs to submit_plan)
- Add PLANNOTATOR_ALLOW_SUBAGENTS env var for #289
- Pass planFilePath to denial feedback template
- Keep existing subagent/build/title guards intact

* fix: address review findings in OpenCode plugin
- Cache agents list (static per session, was fetched every LLM call)
- Remove TOCTOU: drop redundant file.exists() before file.text()
- Eliminate duplicate system.join() by reusing joined string
- Resolve getSharingEnabled() once in submit_plan instead of twice
- Use path.join() instead of string concatenation for file paths

* feat: session-scoped plan files and tool-neutral prompt
Replace plugin-global resolvedPlanFilePath and prompt-path parsing with
per-session plan files at ~/.plannotator/session-plans/opencode/{id}/plan.md.
Remove resolvePlanFilePath() regex (fixes spaces-in-path and cross-session
race). Make planning prompt tool-neutral (no write/edit references) so it
works with apply_patch models. Strip OpenCode's native read-only and
experimental-mode prompt lines before injecting Plannotator's planning prompt.

* feat: directory-based plan storage with path validation
Replace session-scoped plan files with a shared plan directory at
~/.plannotator/session-plans/opencode/. Agent picks the filename,
submit_plan takes a path arg and validates it (absolute, inside plan
dir, exists, readable, non-empty) with canonical path checks to
defeat traversal and symlink escapes. Remove summary and plan string
args. Planning prompt is now tool-neutral and directs the agent to
reuse the same file on feedback, not create new ones.

* fix: use OpenCode's native plans directory for permission compatibility
OpenCode's plan mode permission ruleset only allows edits to
.opencode/plans/*.md and $XDG_DATA_HOME/opencode/plans/*.md.
Our custom ~/.plannotator/session-plans/opencode/ path was blocked
by PermissionDeniedError at the tool level regardless of prompt
stripping. Switch to the XDG path that OpenCode already allows.

* feat: exploration-first planning prompt
Restructure the planning prompt as a phased workflow:
Explore → Ask → Write → Submit. The agent now explores the
codebase before creating a plan file or asking questions,
producing better-researched plans for existing codebases.
Greenfield tasks can skip straight to questions.
