## Thinking Path
> - Paperclip manages AI agents and their work.
> - The new runner gives agents dedicated tools for common tasks.
> - Some API operations and parameters have no dedicated tool.
> - Agents need a controlled way to find and use those operations.
> - This pull request adds API search and calls through the real server
routes.
> - Existing tools remain the preferred path. The new tools are disabled
by default.
> - Paired tests measure correctness, tool choice, cost and time.
## Linked Issues or Issue Description
**Subsystem affected**
Paperclip Runner contracts, production tool authority and the server API
catalog.
**Problem or motivation**
The runner cannot use much of the API described by the old Paperclip
skill. A generic HTTP client would also let agents bypass runner control
rules.
**Proposed solution**
Add `search_api` and `call_api`. Resolve calls from the mounted API
catalog. Use server-held, run-bound credentials. Preserve route checks
and runner lifecycle rules. Keep the tools disabled until an operator
enables selected companies.
**Alternatives considered**
A dedicated tool for every endpoint would add a large initial prompt. An
unrestricted HTTP tool would weaken authorization and replay controls.
**Roadmap alignment**
This extends the native runner tooling. The repository owner requested
this design and implementation. The roadmap and related open PRs were
checked. No duplicate API escape-hatch PR was found.
## What Changed
- Register two compact fallback tools in canonical contracts and
provider projections.
- Build deterministic API discovery from OpenAPI, mounted experimental
routes and the old skill reference.
- Execute bounded JSON, text, file and download requests through
authenticated HTTP routes.
- Recheck active runs, company access and work modes. Block runner
lifecycle, scheduling, credential and approval bypasses. Keep routine
annotation collaboration available.
- Retain mutation receipts. Report uncertain outcomes without blindly
repeating writes.
- Add a company rollout gate and a durable eval worker with complete
cost accounting checks.
- Record child-task creation in the activity log with the agent and run.
- Add contract, authorization, file, replay and real runnerd/PRP/HTTP
tests.
- Document rollout gates and paid coverage limits. The companion eval
repository retains immutable attempts and reports.
## Verification
- Final app commit `da58370524c3626a744eec20164397c5fb6ba9ef`: all 32
checks passed; the unrelated Storybook visual check was skipped.
Greptile 5/5; no unresolved review threads.
- Full Linux build and recursive typecheck passed. Repository tests were
run by project and serialized shard; all 143 serialized server suites
passed.
- Runner TypeScript: 1,599 passed, two skipped. Rust release: 451
passing test reports. Conformance and replay parity passed. The required
API check passed 837 tests, including runnerd → PRP → authority → real
HTTP.
- Bindings cannot enable API tools without the explicit deployment flag.
Unit and real-authority tests prove the default-off boundary.
- The standalone API check builds and stages its own binary. It passed
after existing staged and debug binaries were removed from the test
container.
- UI and CLI tests passed. Initial environment failures (missing jq,
Docker overlay file identity, and parallel linker memory pressure) and
focused passing reruns are retained. The macOS full runner suite has
platform-specific failures; Linux is the qualified full-check platform.
- Eval harness: 27 tests passed; existing CI discovery ran 86 tests with
two unrelated skips. Credential export rejection is tested against the
actual report command.
- Luna and OpenRouter Sonnet each passed 60 common-workflow runs: ten
workflows, three repetitions per arm, zero unnecessary API fallback.
- Sonnet passed 11 selected capability/contract cases after fixes.
Gemini passed three smoke cases. DeepSeek exceeded the 120-second limit
and remains unqualified.
- Luna's two cost flags received focused follow-up. The original flags
and a later n=1 latency flag remain visible. Sonnet had no cost or
latency increase above 20%.
- The catalog contains 785 entries; 58 were exercised across all stages.
Most operation probes remain unrun and some need additional fixtures.
Authored probes do not establish successful coverage.
- Total conservative accounted cost: $9.875960. Active paid-campaign
time: 88.16/90 minutes. No missing accounting. Later security and
harness fixes have provider-free verification; no paid validation is
claimed for those revisions.

## Risks
- This is a broad authenticated API surface. Keep the default-off gate
until an operator selects initial rollout companies.
- Paid coverage is incomplete. Small regression samples do not prove all
workflows are unchanged.
- A timeout or server failure can follow a committed mutation. The
result reports an unknown outcome and requires state inspection.
- The new definitions add prompt tokens. The report retains cost flags
and cache variation.
- No database migration is required.
- Repository rules require code-owner approval before merge. Technical
CI and automated review are complete.
## Model Used
OpenAI Codex based on GPT-6 assisted with code, tests and review. The
exact serving model ID and context window are not exposed in this
session. It used reasoning, tool calls and code execution.
Eval models: `gpt-5.6-luna` with low reasoning,
`openrouter/anthropic/claude-sonnet-5`,
`openrouter/google/gemini-3.8-flash`, and
`openrouter/deepseek/deepseek-v4-flash-0731`. Attempts retain runtime
versions, model identity, usage and source provenance.
