Implements the Rank #1 public-surface security and hygiene remediation for hummbl-io/nakedagent:
Harden nakedagent/toolcall.py against spoofed closing fences and nested multi-tick mismatches:
Reject tool-call parses when an unmatched bare 3-tick closing fence (```) appears at depth 0 alongside parsed tool calls (__refused__), preventing a spoofed closing fence or untagged inner code block inside a write/patch payload from prematurely terminating the outer block and fabricating an executable shell tool call.
Require nested fence openers inside an open fence of length stack[-1] to have ticks >= stack[-1] per CommonMark rules so a 3-tick line inside a 4-tick markdown ```` block cannot push onto the fence stack and block the 4-tick close.
Add 4 unit tests in tests/test_toolcall.py (TestSpoofedAndNestedFenceHardening).
Remove tracked _review/ directory:
git rm -r _review/ (_review/glm-5-2-review-output.txt) and ignore _review/ in .gitignore.
Add .gitleaks.toml allowlisting the historical false-positive generic-api-key match on slash-separated prose (byte/collection/identifier/integer) in commit a46409d3c7b0b01d78b2936082aff1df435ba4c2 (docs/risk-contract/PILOT-RESULTS.md:L10).
Add ruff.toml, mypy.ini, and pyproject.toml tool configs (#48):
Add ruff.toml, mypy.ini, and matching [tool.ruff], [tool.mypy], and [tool.pytest.ini_options] sections in pyproject.toml as documented in AGENTS.md.
Medium Risk
Changes sit on the security-critical parse-to-execute boundary; behavior is stricter (more refusals) with targeted tests, but any parser regression could block legitimate tool calls or miss edge cases.
Overview Hardens the markdown tool-call parser so spoofed or stray bare ``` closers and nested fence tick mismatches cannot truncate write/patch bodies or turn embedded example shell fences into real executable calls. The parser now flags depth-0 unmatched 3-tick closes and collapses the parse to a single __refused__ result, and only treats inner fence openers as nested when their tick count is at least the current stack top (CommonMark-style 4-tick blocks). Four adversarial unit tests lock in these cases.
Repo hygiene: removes tracked _review/ output from the tree and ignores _review/; adds .gitleaks.toml to allowlist a historical false positive in docs/risk-contract/PILOT-RESULTS.md; adds ruff, mypy, and pytest settings in ruff.toml, mypy.ini, and pyproject.toml.

Summary by CodeRabbit
Bug Fixes
Malformed tool-call blocks with unmatched or spoofed closing fences are now refused instead of being dispatched.
Shorter nested fences inside a tool call are treated as content, helping preserve valid outer calls.
Chores
Added project-wide linting, type-checking, and test-runner configuration.
The parser now refuses certain malformed or desynchronized tool-call fence structures. The pull request adds tests for those cases and configures pytest, Ruff, mypy, and Gitleaks. It also ignores the _review/ directory and removes a review report.
Changes: Tool-call parser hardening
Layer / File(s)
Summary
Fence parsing and refusal behavior nakedagent/toolcall.py, tests/test_toolcall.py
The parser tracks unmatched closing fences, applies a fence-length check to nested markers, and returns a refusal for parsed calls followed by an unmatched closing fence. Four tests cover malformed and nested fence cases.
Development check configuration
Layer / File(s)
Summary
Pytest, Ruff, and mypy settings pyproject.toml, ruff.toml, mypy.ini
The configuration sets pytest paths and test discovery, Ruff target and lint rules, and mypy target, exclusions, and enabled or disabled checks.
Gitleaks allowlist
Layer / File(s)
Summary
Targeted Gitleaks allowlist .gitleaks.toml
The configuration extends Gitleaks default rules and allows the generic-api-key match for the specified path and commit.

Summary
Ignore and remove review report .gitignore, _review/glm-5-2-review-output.txt
The .gitignore excludes _review/, and the review report is deleted.
hummbl-io/nakedagent#49 — The targeted Gitleaks allowlist addresses the reported match at docs/risk-contract/PILOT-RESULTS.md; the change does not establish whether the flagged value is a real credential.
Merge Risk: Moderate · up to 748f6
The secret-scanning allowlist is broader than the single false positive it is meant to cover, so a real secret added later to that file or commit could go undetected. The parser change can also refuse a valid tool call that follows a harmless fenced code block, and the model is not told why. Narrow the allowlist before merging; the other items are minor follow-ups.

Full details: Out of Scope Changes check
Explanation
Linked issue #49 covers only .gitleaks.toml. The other changes at head are not part of #49. They are toolcall.py fence hardening, four tests in tests/test_toolcall.py, removal of _review/glm-5-2-review-output.txt, the _review/ entry in .gitignore, and the tool configs ruff.toml, mypy.ini, and pyproject.toml. The PR objectives state that PR #50 aims to make each of these changes. The changes are therefore declared PR scope, not unrelated changes. No linked issue covers the parser or tool-config changes, so their scope rests on the PR description and objectives. The ruff.toml, mypy.ini, and pyproject.toml changes reference #48. Issue #48 is not in the linked issue set. This assessment did not verify the parser logic or the test results.

Full details: Linked Issues check
Explanation
Linked issue #49 asks for one of two actions. Rotate or scrub the value if it is a real credential. Add a targeted .gitleaks allowlist entry if it is a placeholder. The PR takes the allowlist path. At head, .gitleaks.toml exists. It extends the default rules and adds one allowlist entry. The entry is scoped to commit a46409d3c7b0b01d78b2936082aff1df435ba4c2 and to the path docs/risk-contract/PILOT-RESULTS\.md. This matches the shape the issue recommends. The placeholder classification is not verified. docs/risk-contract/PILOT-RESULTS.md does not exist at head 748f68675568286482dded8ff09cd2c5f1563f0a. It also does not exist at commit a46409d3c7b0b01d78b2936082aff1df435ba4c2. The matched value cannot be read, so the claim that it is slash-separated prose rests on the PR description. The gitleaks scan results in the PR description were not reproduced.
Resolution
Provide evidence that the flagged value at docs/risk-contract/PILOT-RESULTS.md:L10 in commit a46409d3c7b0b01d78b2936082aff1df435ba4c2 is a placeholder and not a credential. Possible evidence: the blob content from the commit that contains the file, or the gitleaks report for that commit. Confirm that the commit hash is reachable from the repository history. With that evidence, this check can be re-assessed as PASS.

Remove the deleted report reference from the documentation.
docs/architecture/architecture.md still states that _review/glm-5-2-review-output.txt contains the full raw output. This change ignores _review/, and the report was removed, so the documented path is unavailable in a checkout. Remove or replace that reference before merging.

Distinguish untagged fence openers from unmatched closers.
A balanced untagged Markdown block before a valid tool call sets unmatched_bare_close. The final check then replaces that valid call with a refusal. Track top-level untagged blocks so their matching fences do not suppress later calls. Continue to refuse tagged calls found inside an untagged block. (raw.githubusercontent.com)

Surface the refusal reason to parser consumers.
This refusal stores its reason in ToolCall.content. The synchronous loop and Sidekick instead report __refused__ as an unknown tool, so the model receives no fence-error reason to correct. Handle the refusal sentinel in both dispatch paths and return its content without invoking a tool. (raw.githubusercontent.com)

Agentic security review of this PR found one medium issue in the new gitleaks allowlist: default OR matching skips an entire historical commit and the listed path for all rules. Other review modules did not report qualifying findings.

🔒 Agentic Security Review
Severity: MEDIUM
This global [[allowlists]] sets both commits and paths but does not set condition = "AND" or targetRules. CI pins gitleaks v8.30.1, which treats an empty allowlist condition as OR, so a commit match or a path match is enough to skip scanning.
Impact: Every file in commit a46409d3… is skipped for all rules, and any present or future content at docs/risk-contract/PILOT-RESULTS.md is skipped in every commit—not only the documented generic-api-key false positive. A later credential added to that path would not be caught by CI.

Gitleaks allowlist uses OR logic
Medium Severity
The new allowlist sets both commits and paths without condition = "AND". Gitleaks 8.30.1 defaults those checks to OR, so every finding in that historical commit and every finding on docs/risk-contract/PILOT-RESULTS.md across history is suppressed.
