Distrust Found Checkouts and Private-Repo Raw Fetches by ptr727 · Pull Request #1036 · ptr727/ProjectTemplate

ptr727 · 2026-08-27T02:46:11Z

Summary

Two Verification Discipline gaps, both surfaced by the same incident transcript (an agent
reading a pre-existing ~/repos/HomeAutomation-Config checkout, then failing to fetch its
content via raw.githubusercontent.com because the repo is private):

Never use local copies you did not install yourself #784: no rule said a checkout already sitting on disk, one this session did not clone
or install itself, is untrusted. It may belong to another concurrent session, sit on a stale
fetch or unexpected branch, or hold unreviewed uncommitted edits. Added a GOVERNANCE.md
"Verification Discipline" bullet distinguishing this from the existing local-clone-staleness
rule, plus a mirrored summary bullet in the agent-conduct skill's "Before Claiming Done".
Update GitHub skill to use gh cli to access private repo content #777: raw.githubusercontent.com 404s identically for a private repository and a
genuinely missing file, so that response cannot answer whether content exists. Added a
bullet documenting gh api repos/<owner>/<repo>/contents/<path>?ref=<ref> as the correct
route when a repo's visibility is not confirmed public, naming the 2>&1-into-base64 -d
decode corruption from the issue's own transcript and calling out verifying the ref before
trusting a 404.

Both are doc-only changes to the hub's own canonical text. scripts/build_dist.py regenerated
the two generated skill distributions (.claude-plugin/fleet-skills/, .github/skills/) from
the single edited source at .agents/skills/agent-conduct/SKILL.md.

Verification

Ran the full local gate set from OPERATIONS.md "Local Verification" (ruff, mypy, the
scripts/tests + spec/audit.py --selftest + gh-write-guard.py --selftest +
test_install.py unittest run, build_dist.py --check, repo_gate.py, prose_lint.py's
full check list, spec/validate.py, docker_lint.py) — all passed.

Summary by CodeRabbit

Documentation
- Updated verification guidance to require fresh repository data or live API reads rather than relying on existing local checkouts.
- Added branch-specific checks before reporting content as unavailable.
- Clarified handling of file retrieval errors, including API-based verification when repository visibility is uncertain.
- Synchronized these updates across the relevant guidance and refreshed the associated source digest.
- Improved the reliability and accuracy of repository content verification.

Verification Discipline had no rule for a checkout already on disk that this session did not create (issue #784): it may belong to another concurrent session, sit on a stale fetch or unexpected branch, or hold unreviewed uncommitted edits, none of which is visible from finding it. Add a bullet distinguishing it from the existing local-clone-staleness rule and requiring a fresh clone or a live API read instead. Also document that raw.githubusercontent.com 404s identically for a private repository and a genuinely missing file, so that response cannot answer whether content exists (issue #777). Point at gh api's contents endpoint for a repo whose visibility is not confirmed public, name the 2>&1-corrupts- base64-decode failure mode from the issue's own transcript, and call out verifying the ref before trusting a 404. Both bullets are mirrored into the agent-conduct skill's Before Claiming Done summary, which surfaces Verification Discipline at its decision moment; scripts/build_dist.py regenerates the two skill distributions.

Harden Checkout and Private Repository Verification

📝 Documentation🕐 10-20 Minutes

AI Description

• Treat pre-existing checkouts as untrusted and require fresh clones or live API reads.
• Use authenticated GitHub contents requests when raw private-repository fetches return ambiguous
404s.
• Regenerate agent-conduct distributions so verification guidance reaches every supported agent.

High-Level Assessment

The current approach is appropriate: keep detailed policy in GOVERNANCE.md, surface concise guidance at the decision point in the canonical agent-conduct skill, and regenerate both distributions through the existing single-source build process. Editing generated copies directly or documenting the rules only in governance would either introduce drift or reduce discoverability.

📝 Walkthrough

Walkthrough

The pull request updates repository verification guidance across governance and agent-conduct skill copies. It requires fresh or live repository state, branch checks before absence claims, and authenticated GitHub Contents API retrieval when raw-content responses are ambiguous. The source digest is updated.

Code Review by Qodo

🐞 Bugs (0)📘 Rule violations (0)📜 Skill insights (0)

1. ~~API pipeline fails open~~✓ Resolved🐞 Bug☼ Reliability

Description

The prescribed gh api ... | base64 -d pipeline reports the decoder's status, so an
API/auth/ref/404 failure can feed empty stdin to a successful decoder and appear as empty content.
This defeats the new rule's purpose by allowing an agent to mistake a failed probe for a valid
content read even though 2>&1 is omitted.

Code

GOVERNANCE.md[173]

+- **A raw-file fetch 404s the same way for a private repository as for a genuinely missing file.** `curl`ing `raw.githubusercontent.com/<owner>/<repo>/<ref>/<path>` returns an indistinguishable 404 whether the repository is private, the ref does not exist, or the path is wrong, so an agent that treats that response as "the content does not exist" has made the same unstated-branch mistake the bullet above names, only over visibility instead of branch. Where a repository's visibility is not confirmed public, read its content through `gh api "repos/<owner>/<repo>/contents/<path>?ref=<ref>"` instead, decoding with `--jq '.content' | base64 -d`. Never merge the error stream into that pipeline with `2>&1`: a failed call's error text flows into `base64 -d` in place of content and corrupts the decode with no clue why. Verify the ref resolves (a commit SHA is unambiguous where a branch name may have moved, been deleted, or never existed on the remote) before reading the 404 as an answer about the content itself.

The documented `gh api ... | base64 -d` pipeline can succeed overall when `gh api` fails because ordinary pipeline status comes from `base64 -d`. Update the guidance so both the API request and decoding failure are checked explicitly.
## Issue Context
The warning against `2>&1` prevents error text from being decoded, but it does not propagate `gh api` failures. Mirror the corrected summary into the canonical skill source and regenerate both distributions and the source digest.

2. ~~Skill duplicates governance rules~~✗ Dismissed📘 Rule violation⚙ Maintainability

Description

GOVERNANCE.md instead of only directing readers there. The generated skill distributions mirror
the same duplication from this source file.

Code

.agents/skills/agent-conduct/SKILL.md[R22-24]

+- **A checkout this session did not create is not ground truth.** One found already sitting on disk may belong to another concurrent session, sit on a stale fetch or an unexpected branch, or hold unreviewed uncommitted edits. Clone fresh or read the live API instead of trusting `git status`/`git remote -v` run against a pre-existing checkout.- **A "does not exist" claim names the branch it was checked against.** A worktree's default branch is not necessarily the one the content lives on: in-flight content on a `release`-model repo lands on `develop` before `main`, per `GOVERNANCE.md` "Branching Model," so check that branch before reporting anything absent repo-wide.+- **A `raw.githubusercontent.com` 404 does not distinguish a private repository from a missing file.** Where visibility is not confirmed public, read content via `gh api "repos/<owner>/<repo>/contents/<path>?ref=<ref>"` and decode with `--jq '.content' | base64 -d`, never `2>&1`'d into that pipe, which corrupts the decode with the error text instead of the payload.

qodo and CodeRabbit both independently caught the same real bug in the gh api content-fetch pipeline this PR just documented: piping straight from gh api into base64 -d reports only the decoder's own exit status, so a failed gh api call (a bad ref, an auth gap, a network error) hands base64 -d nothing to decode, which it does successfully, exit 0. The rule meant to stop an agent from misreading a failed content read now demonstrated the exact failure mode it was written to prevent. Fixed by capturing the API call's own result before decoding it (content=$(gh api ... --jq '.content') && printf '%s' "$content" | base64 -d) so the fetch's exit status gates the decode instead of being discarded, verified with a fake-gh repro (exit 0 on the old direct pipe, exit 1 on the fixed captured form, against a gh that fails outright). Applied to GOVERNANCE.md and the agent-conduct skill source, rebuilt via scripts/build_dist.py. Addresses review findings on #1036 (PRRT_kwDOQ5caqM6crgTj, PRRT_kwDOQ5caqM6crglK)

CodeRabbit's next round caught a real gap the previous fix left behind: the agent-conduct skill's condensed raw.githubusercontent.com bullet dropped the GOVERNANCE.md rule's ref-verification requirement, so an agent reading only the skill summary (not GOVERNANCE.md itself) could still misread a 404 from an invalid or moved ref as proof the content does not exist. Added the missing clause and rebuilt the two generated distributions via scripts/build_dist.py. Addresses a review finding on #1036 (PRRT_kwDOQ5caqM6crl-3)

## Summary Promotes `develop` to `main`, carrying: - #1036 (fixes#784, #777): documents that a checkout already sitting on disk, one this session did not create, is untrusted (may belong to another concurrent session, sit on a stale fetch or unexpected branch, or hold unreviewed uncommitted edits), and that `raw.githubusercontent.com` 404s identically for a private repository and a genuinely missing file, so `gh api repos/<owner>/<repo>/contents/<path>?ref=<ref>` is the correct route when a repo's visibility is not confirmed public. Both `GOVERNANCE.md` "Verification Discipline" and the mirrored `agent-conduct` skill summary were updated; review (qodo + CodeRabbit, Copilot repo-wide quota-exhausted throughout) caught two real bugs in the fix itself along the way (a `gh api | base64 -d` pipe that decodes a failed fetch as an empty success, and a skill-summary bullet that dropped the ref-verification clause), both fixed and verified before merge. 🤖 Generated with [Claude Code](https://claude.com/claude-code)  ## Summary by CodeRabbit * **Documentation** * Strengthened verification guidance for repository-based tasks. * Added checks to ensure existing checkouts and branches are trustworthy before drawing conclusions. * Clarified that missing content must be verified against the correct branch rather than inferred from an unavailable result. * Added guidance for authenticated content retrieval and clearer handling of fetch, access, and decoding failures. * Updated related skill references to keep verification practices consistent across supported environments.
