## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - The Legacy OpenCode adapter runs an agent and its shell tools in the same sandbox. > - A large build can exceed the sandbox memory limit and trigger a kernel OOM kill. > - The kernel can kill OpenCode before its tool, which loses the active turn. > - OpenCode provides a shell environment hook that can change only the tool subprocess. > - This pull request uses that hook to prefer Bash tool processes as OOM victims. > - The benefit is that OpenCode can report a failed tool and continue the task. ## Linked Issues or Issue Description **What happened?** An OpenCode sandbox run ended with exit 137 after a TypeScript process had also been killed. Its cgroup limit was 4 GiB. It had completed useful tool work and had not reached its execution deadline. The original sandbox was deleted, so its historical OOM counters are unavailable. Memory pressure is the leading explanation, not a proven historical kernel diagnosis. **Expected behavior** When a shell tool exhausts sandbox memory, the kernel should prefer that tool over OpenCode where possible. The adapter must preserve configured shell startup, model, permissions and resource limits. **Steps to reproduce** Use a disposable 4 GiB Linux sandbox with OpenCode. Retain a 1,200 MiB buffer in the agent and run a Bash tool with fourteen 250 MiB workers. Compare the same workload before and after installing the generated hook. Record the cgroup memory events, agent exit and final response. Refs: #16844. That PR covers the same protection for Claude. This PR adds the OpenCode-owned hook. Refs: #17254 for the separate shutdown recovery path. This PR does not change retry policy. ## What Changed - Generate a dependency-free OpenCode `shell.env` plugin and a Bash startup file in the isolated runtime config. - Stage those assets only for sandbox execution. Resolve the startup file relative to the copied plugin. - Set child `oom_score_adj` to `1000` on Linux. Keep the parent environment unchanged and honor existing `BASH_ENV` values, including an empty value. - Keep command execution available if the optional plugin cannot be installed or the process priority cannot be changed. - Materialize linked plugin directories inside the isolated config before writing. Keep the operator directory and its plugins unchanged. - Cover relocation, shell output and exit status, operator settings, local execution, remote staging and failed installation. Update the adapter documentation and verification recipe. ## Verification - Red before the fix: the new runtime regression failed because the sandbox shell plugin was absent. The existing 15 runtime config tests passed. The same regression passes with the fix. - Apex first found a host-write risk through linked plugins directories (4/5). A new regression reproduced the host directory modification, then passed after the installer materialized the copied link. The finding is resolved. Apex reviewed current head `df82a8f51725a197c0ea3ebeb942488509f32b34` at 5/5 with no actionable issues remaining. - The full OpenCode adapter suite passes: 87 source tests. The adapter typecheck and map checks pass. - Real sandbox acceptance used the plugin generated from `df82a8f51725a197c0ea3ebeb942488509f32b34` and OpenCode 1.18.34 in a disposable 4 GiB Daytona sandbox. A controlled local model endpoint issued an actual Bash tool call; no real model credentials were used. The tool reported priority `1000`; the parent reported `0`. - Controlled OOM comparison: without the guard, OpenCode was killed by SIGKILL after 8.95 seconds and the cgroup recorded one OOM kill. With the guard, five workers were killed, OpenCode exited `0` after 21.87 seconds, and its final response was `fixture-complete`. The cgroup counter increased by five. Both attempts used the same allocation and workload. The fixture started with a linked operator plugins directory. The installer preserved that directory, staged a real plugins directory, and passed both the process-priority probe and OOM comparison. The fixture allocation was deleted afterward. - The first live probe was not accepted because the harness could not parse the provider response framing. After correcting the decoder, the unchanged plugin passed the probe and the controlled OOM comparison. Both initial disposable allocations were deleted. After the review fix, a third allocation repeated the probe and OOM comparison with a linked plugins directory. That allocation was also deleted. The initial comparison had the same agent-killed/agent-survived result (8.42 seconds without the guard; 19.42 seconds with it). - Repository `pnpm -r typecheck` and `pnpm build` pass. The full CI matrix passes on `df82a8f51725a197c0ea3ebeb942488509f32b34`, including tests, browser shards, Runner checks, build, policy and Apex. [CI run](https://github.com/paperclipai/paperclip/actions/runs/40043947375). - The first full local test attempt had 15 embedded PostgreSQL startup failures. Direct `initdb --version` and `postgres --version` probes showed missing bundled library symlinks and SIGABRT. Running the bundled symlink hydration script restored both executables. All 15 affected cases pass after that setup repair. No product code changed for it. - Two existing workspace tests assumed that new Git repositories have no `main` branch. They failed under the host default branch setting of `main`, then passed with a per-command `init.defaultBranch=master` setting. The global setting was preserved. The full local test command was restarted with hydrated libraries and that controlled fixture default. It had no reported assertion failures when it was stopped after the complete CI matrix passed. It did not complete locally; full-suite verification comes from CI. The first failed invocation was also stopped. - The original tenant task has not been retried or recovered by this PR. Its board API credential is expired. The original hosted workflow and the separate shutdown recovery remain outside this acceptance result. ## Risks - This is a preference, not a memory reservation. It cannot guarantee that OpenCode survives every OOM condition, including memory growth inside OpenCode itself. - The guard applies to non-interactive Bash tools. Other shells ignore `BASH_ENV`. Existing operator startup settings take precedence. - Older OpenCode releases without the shell environment hook will not apply the preference. No model, permission, deadline, memory quota or retry limit changes. - No schema change or migration. ## Model Used OpenAI GPT-6 through Codex, with repository tools and code execution. The exact deployment variant and context window are not exposed by this session. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes: #` / `Refs: #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Paperclip <noreply@paperclip.ing>
Paperclip feature map
Start here when reproducing a user-facing bug, verifying a change, or deciding which surfaces a fix must cover. Each recipe describes what a person can do, where they can do it, the expected result, and the evidence needed to verify it. Product behavior is still governed by the implementation spec.
The sibling agent access map records APIs, agent entry points and permission boundaries for the same capability IDs. Follow the shared map contract when maintaining either map.
IDs and references
Use the existing IDs in issues, PRs, Storybook annotations, tests, and verification evidence:
| Reference | Example | Defined by |
|---|---|---|
| Feature ID | onboarding |
The recipe filename without .md. |
| Capability ID | onboarding/company |
The feature ID plus a key from its Sub-features list, separated by /. |
| Entry-point reference | onboarding.md#web-wizard | The recipe filename plus its entry-point heading. The local entry-point ID is web-wizard. |
For example, report verifying onboarding/company through web-wizard.
Capabilities describe behavior; entry points identify the surface used to exercise
it. Entry-point IDs are separate from generated capability IDs. Both maps and
Storybook use the same full capability IDs. Each child page states its feature
ID; recipe bullets show the full capability ID beside the local key, and access
companions show it beneath the local heading. Local keys remain unchanged for
parsing and existing anchors.
Keep recipe filenames, sub-feature keys, and entry-point keys stable when changing display titles or navigation. Renaming a filename or key changes its references. The section headings below are navigation labels, not additional IDs.

Open the published Storybook guide for the assembled feature and capability index. The Markdown recipes in this directory are the authored source. Each has a same-named agent-access companion.
Run node scripts/storybook-catalog.mjs to generate local navigation in
maps/generated/feature-map.md, maps/generated/agent-access-map.md, and the
Storybook guide. Recipes are discovered automatically from their navigation
metadata; generation does not depend on this high-level index.
Before driving a journey
- Use this checkout's isolated test drive for manual product checks. It creates a temporary instance and prints its URL and data directory. Do not guess that a server on port 3100 belongs to you.
- Record the commit, URL, company, login role, relevant experimental settings, adapter, runtime mode, and live versus simulated dependencies. Use disposable tasks and provider resources. A fresh test drive creates a company and CEO, but no task or first run.
- Use the current navigation and company prefix. Paths in recipes omit that prefix. Record whether the streamlined or production shell is selected; Agent Chat, chat connectors, and the combined Inbox/Tasks view have separate gates. A hidden surface is an unmet prerequisite, not a successful test.
- Run the smallest relevant test first. Vitest commands below run from the repository root after installing dependencies. Playwright recipes use their named configuration and its isolated environment, not an unrelated running instance. Reserve expensive runner/provider tests for the behavior at issue.
- Exercise the actual user action, inspect its result, reload, and verify the persisted state or continuation. Use read-only API checks to corroborate UI evidence; creating state through the API does not prove the creation UI.
For agent-driven acceptance work, start with the Paperclip verification skill for an isolated launch, ownership/readiness checks, browser driving, evidence, and cleanup. It uses this directory as its feature map. The existing dev-workspace run/verify skill and evaluation skill describe runtime ownership and evidence handling. Reuse them; this map introduces no environment launcher, credentials, scheduled job, or second test framework.
Evidence contract
Report each entry point as passed, failed, blocked (with its missing
prerequisite), or not run. Include the feature ID, full capability IDs and
entry-point ID (for example, onboarding/company through web-wizard), plus the
recipe link, commit/environment, user action, expected and observed result,
command/exit code, and evidence links. Screenshots or traces should show both the
action and the discriminating result. Include task/run/request IDs when relevant,
without secrets.
A fix is verified across its affected surfaces only when each has evidence or an explicit reason it does not apply. Shared code alone does not prove parity. Keep product regressions visible; do not change the recipe to bless a failure. For Paperclip-assigned work, attach evidence through the artifact workflow.
Inventory and remaining depth
The generated maps/generated/coverage.json lists the current non-test TSX page
modules and the recipes that directly reference each one. An unreferenced module
is a documentation candidate, not proof that its feature is absent or untested.
Remaining workflow limits live in each recipe. Inventory and example associations
describe documentation scope, not runtime health.
Maintaining the reference
The map documents user journeys. It does not execute them automatically; generated inventories record documentation scope rather than live test health. Product E2E reports reuse these capability IDs through the journey associations. Their coverage view shows which scenarios in a campaign are linked to each capability and the associated test results. An association or passing scenario does not certify the whole capability; unselected and unmapped journeys remain distinct.
When maintaining a recipe, compare its entry points and expected results with
the current source. Check that linked tests still exercise the stated behavior
and that local references still exist. Keep the same-named agent access companion
and stable sub-feature IDs aligned when behavior or access changes. Source-only
access inventory remains distinct from live verification. Run
node scripts/check-maps.mjs after map edits for structural/reference checks;
follow the shared contract for the source and behavioral checks it cannot perform.
Each recipe starts with a small frontmatter navigation record, then an H1:
---
navigation: {"section":"Tasks and conversations","sectionOrder":20,"order":10}
---
The H1 supplies the feature title, and the first paragraph supplies its summary. Orders are local to the section; leave gaps for additions. Equal orders use the stable filename as a tie-breaker. Keep a section's name/order consistent across its recipes. Discovery uses the recipe and companion; keep the readable ID index above aligned when features or capability IDs change.
Optional ### Storybook verification guidance lives inside the recipe's Gotchas
section. Each level-four heading contains a backtick-quoted capability key and
has Scope (ui, cli, or browser),
Storybook, Production, and Sources fields. These are verification instructions
and intentional scope limits, not run results or a required story for every API.
The generated gap report combines this guidance with current story associations.
After frontmatter, each recipe starts with an H1 and a user-visible description, then exactly:
- Sub-features — stable backticked local keys, full capability IDs, and observable behavior/states,
such as
- `company`: `onboarding/company` — create a company. - How to get to it (user POV) — one H3 backticked entry-point ID per surface.
- Driving it with — starts with
Preconditions:; repeat each entry-point H3, withAutomated:andManual:paragraphs. Name test scope and gaps honestly. - Gotchas — misleading look-alikes, feature gates, and invalid evidence.
New or updated entries follow
Poteto's feature-map examples.
Existing entries with a Driving it heading can adopt the named harness when
their recipes are updated. The original format was inspired by
Omnigent's feature map.
Paperclip's recipes and checks follow its own task model and test infrastructure.
