What is repo-task-proof-loop?

A repository workflow for large coding tasks such as features, refactors, migrations, and bug fixes. It keeps task files in the repository and guides work through planning, implementation, evidence gathering, fresh checking, and fixes.

Use it to organize and audit non-trivial coding work and leave proof of its verification in the repository.

It gives a repeatable record of what was planned, built, and verified, including checks from a fresh agent session.

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 skillmds/skillmd --skill repo-task-proof-loop

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	$0.00069	$0.03317
Opus 5.5	$0.00028	$0.01327
Sonnet 5.5	$0.00014	$0.00663

Security

Grade A, and why

repo-task-proof-loop scanned grade A with 0 findings 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 1mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to repo-task-proof-loop — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 257 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Repo Task Proof Loop

Use this skill when the user wants a repeatable, auditable implementation workflow for a non-trivial coding task, especially a feature, refactor, migration, or bug fix that should leave repo-local proof in .agent/tasks/<TASK_ID>/.

All task artifacts created by this workflow must stay inside the repository.

When the examples below mention scripts/task_loop.py, that path is relative to this skill root. Run it while your shell working directory is inside the target repository.

What this skill does

Initializes a strict repo-local task folder under .agent/tasks/<TASK_ID>/
Seeds or updates the required artifact files
Installs project-scoped Codex and Claude subagent templates into .codex/agents/ and .claude/agents/
Updates the repo-root AGENTS.md Codex baseline plus the repo's Claude guide file (CLAUDE.md or .claude/CLAUDE.md) with a managed block that explains the workflow
Guides the agent through a strict loop:
- spec freeze
- builder implementation
- evidence packing
- fresh verification
- minimal fix
- fresh verification again until PASS

Commands this skill supports

Treat the following words as commands when the user invokes this skill:

init <TASK_ID>: create .agent/tasks/<TASK_ID>/, install or refresh subagent templates, and update AGENTS.md plus the repo's Claude guide file
freeze <TASK_ID>: create or refine spec.md from the user task, task file, and repo guidance
build <TASK_ID>: implement the task against the frozen spec
evidence <TASK_ID>: create or refresh evidence.md, evidence.json, and raw artifacts without changing production code
verify <TASK_ID>: run a fresh verifier pass and write verdict.json, plus problems.md when needed
fix <TASK_ID>: apply the smallest safe fix set from problems.md, then refresh the evidence bundle
run <TASK_ID>: execute the full loop from spec freeze through verification
status <TASK_ID>: summarize current artifact status

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.
