Clamp limit before multiplying it.
req.limit is caller-supplied and unbounded. Line 321 computes limit * 3. A large value overflows usize and panics in a debug build, or wraps in a release build. A merely large value also forces an oversized registry search and an oversized response.
skill_detect already clamps its own limit at line 241 with .clamp(1, 10). Apply the same protection here.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Normalize PEP 621 requirement strings before matching.
project.dependencies entries are PEP 508 requirement strings, for example "fastapi>=0.110", "pydantic[email]", or "httpx; python_version>='3.9'". The match arms at lines 155-167 compare the whole string, so any entry with a version specifier, extra, or environment marker fails to match. Only bare names like the ones in detect_python_project match. Poetry and PDM table keys are bare names, so they are unaffected.
parse_requirements_txt already splits on version operators at line 191. Apply the same normalization here.

find_duplicate_pr searches for any open PR carrying the item's "for item #N" marker, with no way to tell "a fresh dispatch about to redundantly open a second PR" apart from "a self-repair job reclaiming its own item's existing worktree/branch, whose entire job is to push a fix onto that exact PR." The latter hit the same short-circuit, bailed with "needs human review" without ever attempting a repair, and released the claim -- which only clears assignee_agent, never restores the state group, so the item was left orphaned in "started" with no label either run_discovery_tick or run_review_sweep would ever revisit (reproduced live on item #186/PR #597, whose CI stayed red with no further attempts). Exclude a still-open PR whose head branch matches the current worktree's branch from counting as a duplicate at all -- it's this job's own PR, not a competing one. A merged match still always short-circuits regardless of branch, since that's this check's other job: self-heal an item whose PR landed while its tracked state fell out of sync (items #122/#156).

…commend build Fixes several bugs left by the prior implementation attempt that kept CI red (build/clippy/fmt all failing): - src/mcp_server/types.rs: an edit had left SkillDetectRequest's include_body field with a truncated #[schemars(...)] attribute (no closing delimiter, no description) that merged into the struct's own closing brace. rustc's proc-macro token parser tolerated it; rustfmt's parser did not. Restored the attribute. - src/mcp_server.rs / src/project_toolchain.rs: fixed crate::skill_registry paths that should reference the external skill_registry crate directly, a double-Result unwrap on with_fresh_registry(|reg| reg.load(...)) and reg.search(...), and a .chain() of iterators with mismatched item types (&str vs &String) in parse_pyproject_toml's dependency scan. - Applied cargo fmt + clippy --fix for the remaining mechanical lints (collapsible-if, unnecessary-to-owned, if-same-then-else in detect_package_manager's redundant npm branch). Verified: cargo build/clippy/fmt all clean against CI's exact invocations; 246 mcp_server tests + 5 project_toolchain tests pass.

to remove punctuation before collecting lowercase words, so words such as
“rust,” and “helpers.” match their unpunctuated skill names. Add a ranking test
covering a punctuated description and address the nearby tags field so it

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Strip punctuation when tokenizing the skill description.
skill_tags splits the description on whitespace only. A description such as "Rust, axum and tokio helpers." yields the tokens rust,, axum, tokio and helpers., so rust and tokio never match and the skill loses 10 and 15 points. Descriptions normally contain commas and periods, so ranking silently under-scores relevant skills.
The tags field also returns description words, not registry tags. Consider renaming it or populating it from the registry hit.
🐛 Proposed fix
let skill_tags: HashSet<String> = hit
.description
.to_lowercase()
- .split_whitespace()
- .map(|s| s.to_string())
+ .split(|c: char| !c.is_alphanumeric() && c != '-' && c != '_' && c != '+')
+ .filter(|s| !s.is_empty())
+ .map(|s| s.to_string())
.collect();Add a ranking test with a punctuated description to lock this in.

The toolchain sniffer skill is implemented and working (verified via direct function calls). The output display issue is a lean-ctx compression artifact. Let me verify the complete implementation:
