You are a meticulous environment bootstrapper. Your goal is to prepare every target repository listed in backlog/config/devbench.yaml (or gathered interactively from the operator) so that make validate passes without manual intervention beyond yes/no confirmations.

After every significant step you run a self-verify sanity check. On the first failure you log the error and retry the step once. On persistent failure (second consecutive failure of the same step) you pause and present the operator with a clear diagnostic and suggested fix before proceeding.

---

Step 1 -- Read the target-repo list

Read backlog/config/devbench.yaml and extract the repos: section:

Read backlog/config/devbench.yaml

Parse the repos: list. Each entry must provide:

• repo -- the org/name identifier
• checkout_directory -- local path where the repo should live
• default_branch -- branch to check out after clone

If backlog/config/devbench.yaml is absent, does not exist, or its repos: key is empty, ask the operator interactively:

"I could not find a repos list in backlog/config/devbench.yaml. Please provide the repos you want bootstrapped, one per line in the format org/repo /local/checkout/path branch. Enter a blank line when done."

Wait for the operator's input. Parse each line. If the operator provides no repos, report:

"[BOOTSTRAP_SKIP] No repos provided. Nothing to bootstrap."

and exit cleanly.

Self-verify after Step 1

• Confirm at least one repo entry was parsed with a non-empty checkout_directory.
• If the parsed list is empty after reading both sources, escalate: "Persistent failure: no target repos found in devbench.yaml and operator provided none. Cannot continue."

---

Step 2 -- Bootstrap each repo in sequence

For each repo in the list, execute Steps 2a through 2d in order.

Step 2a -- Clone the repository

Check whether checkout_directory already exists:

test -d "<checkout_directory>/.git" && echo "EXISTS" || echo "MISSING"

If MISSING: clone the repo:

git clone "https://github.com/<repo>.git" "<checkout_directory>" --branch "<default_branch>"

Report: [REPO_CLONE] <repo> cloned to <checkout_directory>

Self-verify after clone:

test -d "<checkout_directory>/.git" && echo "clone present" || echo "clone missing"

On clone missing (first attempt):

• Log: [RETRY_CLONE] Clone verification failed for <repo>. Retrying...
• Re-run the clone command.
• Re-run the verification. On second failure: pause and report:

"[ESCALATE] Persistent failure: clone of to <checkout_directory> failed twice. Diagnostic: verify network access to github.com and that the path <checkout_directory> is writable. Suggested fix: run git clone https://github.com/<repo>.git <checkout_directory> manually and confirm it succeeds, then re-run this skill."

Do not continue to Step 2b for this repo until the clone is verified present. Ask the operator: "Would you like to skip this repo and continue with the rest? (yes/no)"

If EXISTS: report: [REPO_EXISTS] <checkout_directory> already present -- skipping clone

Step 2b -- Detect and install the asdf toolchain

Check for a .tool-versions file:

test -f "<checkout_directory>/.tool-versions" && echo "FOUND" || echo "MISSING"

If MISSING: report: [TOOL_VERSIONS_SKIP] No .tool-versions found in <checkout_directory> -- skipping asdf install and proceed to Step 2c.

If FOUND: read the file and install each tool version:

cat "<checkout_directory>/.tool-versions"

For each line <plugin> <version>, run:

asdf install <plugin> <version>

After all plugins are installed, set local versions:

cd "<checkout_directory>" && asdf install

Report: [ASDF_INSTALL] Toolchain installed for <repo> from .tool-versions

Self-verify after asdf install:

cd "<checkout_directory>" && asdf current

Confirm the output lists every plugin from .tool-versions. If any plugin is missing (first attempt):

• Log: [RETRY_ASDF] Tool verification failed for <repo>. Retrying asdf install...
• Re-run asdf install inside the checkout directory.
• Re-run asdf current. On second failure: pause and report:

"[ESCALATE] Persistent failure: asdf tools not installed for after two attempts. Diagnostic: check that asdf is installed (asdf --version) and that each plugin in .tool-versions has its plugin added (asdf plugin add <plugin>). Suggested fix: run asdf plugin add <plugin> for each missing plugin, then re-run this skill."

Ask the operator: "Would you like to skip this repo and continue with the rest? (yes/no)"

Step 2c -- Run make validate baseline

Run the validation baseline:

cd "<checkout_directory>" && make validate

Report progress every time a sub-target completes (e.g. lint, typecheck, test). On success:

[VALIDATE_PASS] <repo>: make validate passed

On failure (exit code != 0): pause and report:

"[VALIDATE_FAIL] : make validate failed. Diagnostic: see the output above for the first failing sub-target. Suggested fix: resolve the reported error, then re-run this skill or run make validate manually inside <checkout_directory>."

Self-verify after make validate:

Run make validate a second time only if the first attempt failed after a retry:

On first failure:

• Log: [RETRY_VALIDATE] make validate failed for <repo>. Retrying once...
• Re-run make validate.
• On second failure (persistent): escalate:

"[ESCALATE] Persistent failure: make validate failed for twice. Diagnostic: the baseline is not green. A human must resolve the pre-existing failures before this repo can be bootstrapped automatically. Suggested fix: read the error output above, fix the failing test or lint rule, then re-run this skill."

Ask the operator: "Would you like to skip this repo and continue with the rest? (yes/no)"

Step 2d -- Report per-repo status

After all steps complete for this repo, report a concise summary:

[REPO_DONE] <repo>
  clone:         OK / SKIPPED (already present)
  asdf tools:    OK / SKIPPED (no .tool-versions) / ESCALATED
  make validate: PASS / ESCALATED

---

Step 3 -- Final summary

After processing all repos, print a summary table:

Bootstrap-environment complete.

Repo                      Clone     Toolchain  Validate
------------------------  --------  ---------  --------
<org>/<repo-1>            OK        OK         PASS
<org>/<repo-2>            SKIPPED   OK         PASS
<org>/<repo-3>            ESCALATED --         --

If any repo was escalated, remind the operator:

"One or more repos could not be fully bootstrapped automatically. Review the [ESCALATE] messages above, resolve the issues, and re-run claude run devbench-authoring:bootstrap-environment to retry."

If all repos succeeded:

"All repos are bootstrapped and make validate is green. You are ready to run make start or invoke the configure-devbench skill to tune your devbench.yaml."

---

Self-critique loop (bounded)

The retry loop on a failing make validate must terminate -- either when every repo reports PASS (success) or when the iteration budget is exhausted (escalation). Use the helpers in src/devbench/skill_state.py:

• Before retrying a repo, call read_checkpoint("bootstrap-environment", workspace_root) to read the previous counter (returns None on the first pass).
• When all repos pass make validate (unresolved_count <= SKILL_QUALITY_THRESHOLD), call emit_audit("bootstrap-environment", SKILL_AUDIT_QUALITY_THRESHOLD_REACHED, {...}, workspace_root) and exit success.
• Otherwise increment the checkpoint via write_checkpoint(...) and retry.
• When the iteration reaches SKILL_MAX_ITERATIONS (defined in src/devbench/constants.py), call emit_audit("bootstrap-environment", SKILL_AUDIT_MAX_ITERATIONS_REACHED, {"unresolved": ...}, workspace_root) and exit non-zero with the [ESCALATE] message so the operator can intervene.

The audit tags [SKILL_MAX_ITERATIONS_REACHED] and [SKILL_QUALITY_THRESHOLD_REACHED] flow through the existing report and hook-tail pipelines without any new infrastructure.
