A coding-agent workflow for fixing one reported software defect by reproducing it, adding a failing test, and making the smallest fix.

Use it to investigate a specific bug in a Git worktree, verify the reported failure, fix it, and prove the test catches the old behavior.

It reduces guesswork and leaves a test that can detect the same defect if it returns.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add IncomeStreamSurfer/paperclip-surfers --skill paperclip

Clone the repo

git clone --depth 1 https://github.com/IncomeStreamSurfer/paperclip-surfers

Made for: Claude Code, Codex.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00075	$0.05174
Opus 5	$0.00037	$0.02587
Sonnet 5	$0.00015	$0.01035
Haiku 4.5	$0.00007	$0.00517

Measured 11d ago against content hash c1a3fd20338e, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-11, from the pricing page.

Security

Grade A, and why

paperclip scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

If you use direct `curl` during these tests, include `X-Paperclip-Run-Id` on all mutating issue requests whenever running inside a heartbeat.

How it starts

The opening of the file, as written. The whole thing — 366 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Paperclip Skill

You run in heartbeats — short execution windows triggered by Paperclip. Each heartbeat, you wake up, check your work, do something useful, and exit. You do not run continuously.

Authentication

Env vars auto-injected: PAPERCLIP_AGENT_ID, PAPERCLIP_COMPANY_ID, PAPERCLIP_API_URL, PAPERCLIP_RUN_ID. Optional wake-context vars may also be present: PAPERCLIP_TASK_ID (issue/task that triggered this wake), PAPERCLIP_WAKE_REASON (why this run was triggered), PAPERCLIP_WAKE_COMMENT_ID (specific comment that triggered this wake), PAPERCLIP_APPROVAL_ID, PAPERCLIP_APPROVAL_STATUS, and PAPERCLIP_LINKED_ISSUE_IDS (comma-separated). For local adapters, PAPERCLIP_API_KEY is auto-injected as a short-lived run JWT. For non-local adapters, your operator should set PAPERCLIP_API_KEY in adapter config. All requests use Authorization: Bearer $PAPERCLIP_API_KEY. All endpoints under /api, all JSON. Never hard-code the API URL.

Manual local CLI mode (outside heartbeat runs): use paperclipai agent local-cli <agent-id-or-shortname> --company-id <company-id> to install Paperclip skills for Claude/Codex and print/export the required PAPERCLIP_* environment variables for that agent identity.

Run audit trail: You MUST include -H 'X-Paperclip-Run-Id: $PAPERCLIP_RUN_ID' on ALL API requests that modify issues (checkout, update, comment, create subtask, release). This links your actions to the current heartbeat run for traceability.

The Heartbeat Procedure

Follow these steps every time you wake up:

Step 1 — Identity. If not already in context, GET /api/agents/me to get your id, companyId, role, chainOfCommand, and budget.

Step 2 — Approval follow-up (when triggered). If PAPERCLIP_APPROVAL_ID is set (or wake reason indicates approval resolution), review the approval first:

GET /api/approvals/{approvalId}
GET /api/approvals/{approvalId}/issues
For each linked issue:
- close it (PATCH status to done) if the approval fully resolves requested work, or
- add a markdown comment explaining why it remains open and what happens next. Always include links to the approval and issue in that comment.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

paperclip is a skill published in the GitHub repository IncomeStreamSurfer/paperclip-surfers (74 stars, last pushed 5mo ago), licensed MIT. It adds 75 tokens to every session and 5,174 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

Debugging Testing Unit testing

testing

Skill validation framework PLUS daily test-suite health and regression intelligence. Validates skill conformance (frontmatter, manifest coverage, resolver coverage). Runs the project test suite in tiered phases (unit / evals / integration / system health), classifies failures, and produces a regression-aware report.
