parcha-skills
Our collection of portable Agent Skills for Claude Code, Codex, and pi.
| Skill | What it does | Cross-harness note |
|---|
hands-free | Calls your phone when the coding agent needs an answer or approval. | Same Python/Vapi contract in all three harnesses. |
parable | Plans implementation batches, routes work to cheaper executors, verifies, and reviews. | Claude/native subagents are used only when available; stock pi needs a configured CLI-backed executor. |
cascade | Carries large projects through verifiable tasks and parallel work. | Keeps a living task graph; executes serially when parallel tools are unavailable. |
recall | Indexed local search over prior Claude Code and Codex sessions. | Runs from pi, but does not index pi's own transcripts yet. |
recap | Reconstructs everything observable that happened in one exact coding-agent session. | Uses Recall's Claude/Codex evidence; pi can run it but is not yet an indexed source. |
tether | Keeps Slack threads attached to the exact agents that created them. | Codex and Claude Code resume natively; stock pi publishes as a headless run. Requires a separately installed private runtime. |
desloppify | Turns whole-codebase slop into evidence-backed cleanup with Peter O'Malley's official engine. | One canonical workflow selects honest native or prepared-packet review routes per harness. |
autoqa | Points at any repo, discovers how it runs, QAs the live app end-to-end with a witnessed report, and pairs its UI witnesses with base-instance captures as the PR's Before / After. | Uses whatever browser tooling the harness has; API/CLI checks work everywhere. |
precap | Recaps a task before doing it: a grounded, past-tense account of the finished work that long-running agents check themselves against for drift. | Pure markdown plus a stdlib Python checker; identical in all three harnesses. |
tdd | Red before green at pre-agreed seams, one vertical slice per cycle, regression-first bug fixes. | Pure markdown; identical in all three harnesses. |
blast-radius | Finds what a diff breaks beyond the diff and proves the one safety fact by running real code. | Invocation only (disable-model-invocation: true); parallel reviewer subagents are used where the harness has them. |
review-loop | Drives every reviewer thread on a GitHub PR (Greptile, Devin, humans) to zero unresolved in bounded iterations. | GitHub only, through the caller's authenticated gh; identical in all three harnesses. |
verify-release | Confirms the intended candidate is live in the target environment and the changed path works there, with live evidence. | Uses whatever deployment tooling and observability the repo already has; calls autoqa for matrix coverage. |
blast-radius | cursor/plugins, pstack/skills/blast-radius | Lauren Tan |
tdd | cursor/plugins, pstack/skills/tdd, adapted from a bug-fix-only workflow into a general red-green reference | Lauren Tan |
unslop | Cuts AI tells from anything a human will read. | Pure markdown; identical in all three harnesses. |
The skill payloads are canonical skills/<name>/SKILL.md directories. Harness-specific
manifests package those same files; there are no Claude/Codex/pi forks to drift apart.
Skill roles in the PR lifecycle
Each shared skill has one job in the lifecycle of a pull request. A repo-specific orchestrator
calls the skill by name and never copies its body.
| Stage | Skill | Job, in one line |
|---|
| Start | precap | Write the finished-task recap first; detect drift against it. |
| Build | tdd | Red-green at pre-agreed seams. |
| Prove | blast-radius | Find what the diff breaks beyond the diff; prove the one safety fact by running code. |
| Prove | autoqa | Does the running app behave? Witnessed feature-by-modality matrix, baseline plus diff cases. |
| Describe | autoqa | The same run's UI witnesses, paired with base-instance captures, become the PR's Before / After section. |
| Review | review-loop | Drive every reviewer thread (bots and humans) to zero, bounded. |
| Release | verify-release | Is the intended candidate live in the target environment and does the changed path work there? |
| Everywhere | unslop | Cut AI tells from anything a human reads. |
evidence is a rule, not a skill. It stays the always-on snippets/evidence
block, and autoqa owns the witness contract (no witness, no verdict; PASS, FAIL, UNTESTED
with reason, SKIPPED, BLOCKED). blast-radius proves a single fact by running code; autoqa
exercises the app through its entry points and, from the same browser session, produces the
paired before/after captures the PR body shows. The two do not overlap: analysis and execution.
Sources and credits
Some skills in this collection are vendored or adapted from other people's work. Each such
package keeps the upstream license file in its directory and a Provenance section in its README
listing every change made here.
verify-release was written for this collection and carries the repository's MIT license.
Instruction snippets
snippets/ contains harness-neutral blocks for always-loaded agent
instruction files (AGENTS.md, CLAUDE.md). Skills load on demand through
discovery or invocation; a snippet applies to every session unconditionally.
Use a snippet when a rule must hold even in sessions where no skill is loaded.
| Snippet | Purpose |
|---|
effective-comms | Makes responses answer-first, concrete, structured, and brief by default, and bans marketing rhetoric in technical writing, while preserving safety and completeness exceptions. |
evidence | Ties claims to witnessed evidence and keeps sensitive evidence out of public repositories. |
control | Preserves user control over consequential actions and gives errors a bounded recovery path. |
systems-thinking | Prevents local fixes from making the larger system worse without blocking bounded work. |
The install commands below cover skills only. To install a snippet, paste its
AGENTS.md block near the top of your root instruction file and keep the
<!-- name:start/end --> markers so tooling can update the block in place.
Install with skills.sh

npx skills add Parcha-ai/parcha-skills --skill review-loop
npx skills add Parcha-ai/parcha-skills --skill verify-release
npx skills add Parcha-ai/parcha-skills --skill unslop
Add --global for a user-level install or --agent claude-code, --agent codex, or
--agent pi to choose a destination explicitly. The skills.sh CLI discovers the same canonical
payloads used by the native installs below; npm publication of the individual packages is not
required.
Recall and Tether are instruction-only packages here. Their engines, runtimes,
installers, and deployment configuration are maintained separately. Install the
systems through your organization's private distribution before using the skills.

with /skill:<name>, for example /skill:hands-free, /skill:autoqa, or /skill:review-loop.
Compatibility checks
The local gate runs all fifteen skills across the three harnesses for native installation,
discovery, and credential-free smoke checks. Raw test output stays local and is not committed.
Run the local gate with:
npm test
for package in hands-free parable cascade recall recap tether desloppify autoqa precap tdd blast-radius review-loop verify-release unslop; do (cd "$package" && npm test); done
python3 scripts/prove_portability.py --output /tmp/unc-skills-portability
